Fang Gu, MengYing Gao, XueFeng Wang, MeiQi Lv, JinLong Zuo, Chong Tan, Zhi Xia, JunSheng Li

Czech J. Food Sci., 2026, 44(1):71-81 | DOI: 10.17221/20/2025-CJFS

Northeast China boasts abundant resources of cold mountain grapes. This study focused on three varieties of cold mountain grape brandy, Beibing Hong (BBH), Shuanghong (SH), and Zuoshanyi (ZSY), with varying ageing periods to investigate changes in their physicochemical properties, nutrients, and aroma compounds. Results showed that alcohol content and pH gradually decreased with ageing, while total acidity (including inorganic acids) increased. Specific organic acids declined over time, whereas polyphenolic compounds increased with longer ageing. Furthermore, the total quantity of aroma substances in all three brandies was positively correlated with ageing duration, with 18-month-aged BBH brandy exhibiting the highest content and the richest aromatic variety. Clustering analysis via heat maps revealed that brandies aged 12 and 18 months grouped together, showing that ageing time correlated positively with most esters and alcohols and negatively with acids. No significant variations were observed in the contents of terpenes, aldehydes and ketones among the three brandy varieties.

This study aimed to evaluate the effects of dietary administration of peppermint (Mentha piperita) alone and in combination with southernwood (Artemisia abrotanum) on performance, body and carcass composition, physicochemical characteristics, and amino acid composition of breast meat in broilers under Eimeria challenge. A total of 160 14-day-old male broilers (Ross 308) were randomly assigned to four dietary groups: the control (C) group was fed a basal diet; the CC group received a grower diet containing the coccidiostat robenidine; the M group was fed the diets with the addition of 20 g peppermint/kg of diet; the MS group was fed the diets with the addition of 10 g peppermint + 10 g of southernwood/kg of diet. The addition of peppermint to the diet increased final live weight compared to the CC group (P < 0.05). The highest value of dressing percentage was found in the M group as compared to the CC group (P < 0.01) and C group (P < 0.05). Compared with the C group, a higher intramuscular fat content was found in the breast meat of broilers in both the M and MS groups (P < 0.01; P < 0.05, resp.). Concerning the colour of meat, lower values for yellowness b* and chroma C* characteristics were observed in the C group compared to the MS group (P < 0.05) and mainly to the M group (P < 0.01). In spite of the lower crude protein content (P < 0.05) in the meat of the MS group, the highest content of all essential amino acids (P < 0.05) as well as the total content of all assessed amino acids (P < 0.01) were found in the meat of the MS group, resulting in a considerable increase in the nutritional value of the breast meat proteins of these broilers.

Anthracnose is one of the most destructive diseases that limits pepper production and quality worldwide. In this study, the causal agent of anthracnose in red chilli pepper in Southern Vietnam was collected and identified based on morphological characteristics and multilocus sequence regions (ITS, β-tubulin, GPDH, ACT). The antifungal activity of Bacillus amyloliquefaciens and Pseudomonas fluorescens was evaluated in vitro and in vivo under greenhouse conditions. The results revealed that the morphological analysis categorised the Colletotrichum isolates into three species: C. acutatum, C. gloeosporioides, and C. scovillei. Sequence analysis of the four genes confirmed that C. scovillei was the causal agent of anthracnose in chilli pepper in Southern Vietnam. B. amyloliquefaciens and P. fluorescens bacteria demonstrated antifungal activity against C. scovillei in vitro, with mycelial growth inhibition rates ranging from 20.79% to 78.69%. The consortium of B. amyloliquefaciens CC-LD2.4, P. fluorescens CC-FN1.1, and P. fluorescens O-BT1.2 achieved 84.4% control efficacy at 7 days after inoculation (DAI), which declined to 68.5% at 14 DAI and 41.7% at 21 DAI, at the flowering stage, and achieved 100% control efficacy at the fruiting stage. B. amyloliquefaciens CC-LD2.4 showed very high chitinase, protease, and cellulase activities (halo diameter of 26.7 mm, 22.7 mm, 21.5 mm), whereas P. fluorescens CC-FN1.1 was very high in protease and cellulase (14.3 mm, 12.4 mm) but weak in chitinase (5.1 mm), and P. fluorescens O-BT1.2 exhibited overall lower activities (3.4–9.9 mm). There is still considerable room to optimise bacterial consortia to develop bio-fungicides that meet the requirements for an alternative or advanced solution for controlling anthracnose in red chilli peppers in sustainable agriculture.

J. For. Sci., 2011, 57(11):483-490 | DOI: 10.17221/119/2010-JFS

The seed production area (SPA) is an improved plantation managed for production of quality seeds for a large-scale plantation programme. The soil nutrient is one of several factors affecting seed production among SPAs. The status of soil nutrients and their effect on seed production are poorly understood. Hence, the present study was undertaken in 20 seed production areas located in different seed zones of Karnataka, South India. Results showed that there was a greater variation among SPAs in various soil properties like soil pH, organic carbon, available NPK (nitrogen, phosphorus and potassium). Some of the studied parameters recorded significant variations among three different depths: 0-20 (top), 20-40 (middle) and 40-60 cm (bottom). For instance, organic carbon and available potassium showed significant variations at different depths, where the highest content was recorded in the top layer, followed by middle and bottom layers. Considering associations between soil properties and tree growth, organic carbon was positively associated with dbh (diameter at breast height; r = 0.500), stem roundness (r = 0.351) and stem volume (r = 0.250). Similarly, available nitrogen positively influenced the stem volume (r = 0.250). Though the fruit yield varied among SPAs, none of the studied soil parameters showed a significant influence on fruit yield indicating that some other factors like genetic ones, phenology, rainfall overlapping with peak flowering might control it. Data on site quality showed that all existing SPAs studied were growing in poor site conditions, however, this could be one of the factors affecting overall seed yield among SPAs. Hence, it is recommended to undertake a few important silvicultural interventions like application of fertilizer/organic manure, soil working, spraying of floral hormone and others to improve the existing seed production level.

Nitrogen management and irrigation methods play crucial roles in determining rice’s grain yield and quality (Oryza sativa L.). However, limited knowledge exists on how interactions between nitrogen forms and irrigation regimes regulate starch-metabolising enzyme activity to influence rice yield and quality. A soil-growth experiment was conducted using a high-lodging-resistance rice cultivar under three irrigation methods, namely, submerged irrigation (0 kPa), alternate wetting and moderate drying (−20 kPa), and alternate wetting and severe drying (−40 kPa), as well as three nitrogen forms, namely, ammonium nitrogen (NH4+-N), mixed ammonium + nitrate (50 : 50), hereafter denoted as 50 : 50, and nitrate nitrogen (NO3-N). Results indicated that compared with the other treatments, alternate wetting and moderate drying interacted with 50 : 50 treatment, resulting in the following: improved grain yield by 11.7–21.0%, milling, appearance, eating and cooking, and nutritional qualities including milled-rice and gel consistency; and decreased chalky rice, chalky size, chalky degree, amylose content, and protein content by 20.0–23.1, 29.6–33.3, 44.1–48.5, 6.2–9.6 and 10.1–13.9%, respectively. The activities of adenosine phosphate glucose pyrophosphorylase (AGPase), starch synthase (SS), starch-branching enzyme (SBE), and adenosine triphosphate (ATP) enzyme in the grains also improved, with an increase of 20.0–35.0, 11.8–20.0, 13.6–26.3 and 21.2–39.6%, respectively. Conversely, severe drying and NO3-N treatment negatively impacted grain yield and quality due primarily to decreased SS activity in grains under each irrigation method. Correlation analysis showed that starch-metabolising enzyme (AGPase, SS and SBE) activity at 14 days after anthesis (DAA) and 28 DAA exhibited a positive correlation with grain yield, milling quality and gel consistency, whereas negatively correlated with appearance and nutritional qualities. In summary, the adoption of alternate wetting and moderate drying and 50 : 50 interaction treatment can synergistically boost grain yield by increasing the filled-grain rate and 1 000-grain weight and enhance grain quality of rice by upregulating the activities of starch-metabolising enzyme activity.

Plant Soil Environ., 2025, 71(2):109-122 | DOI: 10.17221/197/2024-PSE

Covering hop waste composting piles with semipermeable membrane after the thermophilic phase until spring, when the compost was ready to use, reduced the volume of leachate and leached nutrients amounts significantly; there was a negligible amount of leachate and low amount of leached nutrients during winter and spring at all treatments. At treatments with additives (biochar, preparation effective microorganisms) and larger percent of particles of 2–5 cm, it was indicated that composting pile should probably also be covered in the first months of composting and be opened only when turning/mixing it; on the other hand, the amount of leachate was much lower in a pile without additives and particles of 2–10 cm by the time of covering (2.2- and 2.5-fold less respectively) and the amount of leached nutrients as well. All treatments produced compost without a bad smell, had a total nitrogen content greater than 2%, could be considered as mature (the C : N ratio was below 20) and stable, and the biomass hygienisation threshold was reached. However, there were some significant differences among them. The compost of the pile with added biochar and starting hop waste biomass particles of 2–5 cm was considered phytotoxic (germination index of radish was 31%); also, its other results were less promising in comparison to other treatments. The pile with no additive and the starting particles of waste hop biomass 2 to 10 cm, mixed properly related to regular temperature measurements in the thermophilic phase, reached the best results; the leachate amount and leaked nutrients amount were significantly the lowest, while the final compost contained significantly higher amount of nutrients and had the highest germination index.

Overgrazing affects typical steppe community in ways similar to grasslands in other areas. Exclusion of livestock grazing is one of the main management practices used to protect grasslands. However, it is not known if long-term exclusion of livestock grazing has positive effect on above- and belowground community properties in typical steppe of the Loess Plateau. We studied the long-term (20-year) cumulative effects of exclusion of livestock grazing on above- and belowground community properties compared with that before exclusion of livestock grazing in a typical steppe of the Loess Plateau, NW China. Our results show that twenty-year exclusion of livestock grazing significantly increased above- and belowground biomass, species richness, cover and height for five different communities. Most of belowground biomass was in the 0-20 cm horizon and grazing exclusion increased biomass especially at the depth of 0-10 cm. Our study suggests that long-term exclusion of livestock grazing can greatly improve community properties of typical steppe in the Loess Plateau.

Khojiakbar Khasanov, Masharif Bakiev, Oqil Rasulov, Nodira Babajanova, Ilhom Abdurahmanov

Res. Agr. Eng., 2025, 71(3):143-154 | DOI: 10.17221/20/2025-RAE

This study explores the construction of small reservoirs (SRs) as a strategic solution to address water scarcity in Kashkadarya Province, Uzbekistan, where agricultural productivity is heavily dependent on irrigation. By utilising geographic information system (GIS) and remote sensing (RS) technologies, optimal locations for reservoirs were identified, focusing on improving the water availability for irrigation during critical periods. The research highlights the socio-economic and environmental benefits of SRs, including enhanced agricultural yields, increased employment opportunities, and reduced reliance on energy-intensive pumping stations. The findings indicate that the construction of an 18 Mm3 reservoir in the Ayakchisoy River could supply water to 26.5 thousand hectares, thereby improving the region’s resilience to climate variability. This approach offers a sustainable framework for managing water resources in arid regions, contributing to food security and economic stability.

Plant Soil Environ., 2024, 70(3):125-141 | DOI: 10.17221/199/2023-PSE

In the present study, a field establishment was initiated in 2018 with eight treatment conditions using biochar application rates of 0, 10, 20, or 30 t/ha and nitrogen application rates of 0 or 150 kg/ha. After two years, the impact of biochar on carbon-nitrogen distributions, soil aggregate stability, and wheat yields was then assessed. The predominant mechanical aggregates after two years were > 5 mm and 2–5 mm granular aggregates, with notable increases in the amounts of these aggregates following the application of biochar with or without nitrogen that coincided with an increase in soil aggregate mechanical stability. Relative to control conditions, aggregate mean weight diameter (MWD) and geometric weight diameter (GMD) values rose by 17.6% and 24.3% for biochar with nitrogen treatment (N: 150 kg/ha; biochar: 20 t/ha), respectively. Biochar application alone and the application of both biochar and nitrogen fertiliser were associated with 6.4–20.2% and 20.7–42.7% increases in spring wheat yields, respectively. Overall, the results of these analyses highlight the value of applying biochar to improve soil quality and boost crop yields proximal to the study site. This study provided the scientific basis for the rational fertilisation and scientific management of biochar combined with nitrogen fertiliser in the irrigation area of Northern Xinjiang, China.

Drip irrigation is a highly efficient method for watering crops, as  it delivers water directly to the roots and minimises wastage due to evaporation or runoff. This paper presents the development and implementation of  a low-cost drip irrigation control system that uses both time- and soil sensor-based approaches. The system’s efficiency was compared through a field experiment of melon growing, divided into three categories and four replications using a completely randomised design. The treatments include: T1 [time-based irrigation (TBI)], T2 [soil moisture-based irrigation (SMI)], and T3 [hand watering irrigation system (HWI)]. Results indicated that the TBI technique resulted in faster plant growth compared to the other treatments, as evidenced by increased leaf widths, lengths, numbers, and stem diameter. All irrigation techniques showed significant differences in yield characteristics, with TBI and SMI producing no differences in the first flowering day of female fruit widths, lengths, and weight of melon. However, the HWI treatment resulted in lower fruit length and weight yields. Cost analysis showed that the system is beneficial as  a very low-cost device that is affordable, precise, and useful for measuring and controlling irrigation-related parameters for melon cultivation.

Olivia Peters, Samuel I. Haruna

Soil & Water Res., 2024, 19(3):154-167 | DOI: 10.17221/27/2024-SWR

Soil water energy determines soil water balance, plant water uptake, and soil thermal properties, but the effects of cover crops (CCs) on in situ measured soil water energy and temperature are not well understood. This study investigated how CCs affect in situ measured soil water potential (SWP), temperature, and saturated hydraulic conductivity (Kfs) during 2 years, with the hypothesis that CC-induced water transpiration can lower SWP. The CCs used included crimson clover (Trifolium incarnatum L.), winter wheat (Triticum aestavum L.), hairy vetch (Vicia villosa), oats (Avena sativa), triticale (Titicale haxaploide Lart.), barley (Hordeum vulgare L.), flax (Linum usitatissimum L.), and winter peas (Lathyrus hirsutus L.). Soil water potential and temperature sensors were installed at 0–10, 10–20, and 20–30 cm depths. Additionally, Kfs was measured in situ using a Guelph permeameter. Results showed that actively growing CCs can lower SWP, leading to increased water transpiration from the field compared with no cover crop (NC) management. Also, by lowering soil temperature, CCs can increase evapotranspirational efficiency compared to NC management. Further, by increasing evapotranspirational efficiency, CC, management resulted in increased subsurface water infiltration and storage as shown by higher Kfs values compared to NC management. In general, CCs have the potential to reduce SWP and temperature during their growth stages and this can be beneficial to seed germination and microbial activities.

J. For. Sci., 2014, 60(9):394-399 | DOI: 10.17221/14/2014-JFS

The purpose of this study is to facilitate the detection of provenances relevant to the reforestation practice in Bulgaria. Studies were carried out in a Douglas-fir provenance trial plantation established at an altitude of 800 m a.s.l. on the northern slopes of Rila Mountain. To establish the productivity, assess the stands and rank provenances biometric procedures, methods of descriptive statistics and ANOVA were used. The diameter at breast height, average height, dominant height, total growing stock volume, assortment timber structure and survival of trees were analyzed in the stands of 55 Douglas-fir provenances. The provenances were characterized in terms of productivity of forest stands at 20 years of age and their ability to produce high quality timber was evaluated. Provenances: Newhalem No. 4 (Seed zone 402), Darrington No. 7 (Seed zone 403), Parkdale No. 19 (Seed zone 661) and Idanha No. 29 (Seed zone 452) have been recommended. Among the recommended provenances are those with growing stock volume with branches from 296 to 354 m3.ha-1, mean annual increment from 14.8 to 17.7 m3.ha-1 and dominant heights of up to 17.9 m.

Vet Med - Czech, 2021, 66(6):257-265 | DOI: 10.17221/5/2020-VETMED

The aim of this study is to evaluate the outcome of the treatment on twenty wild birds presenting with fractures that were stabilised with modified Meynard external fixators. The study material consisted of a total of twenty birds of eight different species, six white storks (Ciconia ciconia), one eastern imperial eagle (Aquila heliaca), one European honey buzzard (Pernis apivorus), one long-legged buzzard (Buteo rufinus), three common buzzard (Buteo buteo), one northern goshawk (Accipiter gentilis), one Armenian gull (Larus armenicus), and six yellow-legged gulls (Larus michahellis), which were diagnosed with fractures in their extremity bones following clinical and radiological examinations. The lesions of the twenty cases evaluated in the study were diagnosed as humerus fractures in nine cases, ulna fractures in three cases, tibiotarsus fractures in seven cases and a femur fracture in one case. The external fixators were removed between weeks five and nine postoperatively. While healing was seen in twelve of the twenty evaluated cases, the complete functional recovery occurred in six of these and they were released into nature. It was concluded that modified Meynard external fixator, which was made applicable for fractures in birds, could be an alternative method for fracture treatments in wild birds.

Czech J. Anim. Sci., 2013, 58(8):375-380 | DOI: 10.17221/6904-CJAS

The effects of Aroclor 1254 on the secretion of luteinizing hormone (LH) and 17,20β-dihydroxy-4-pregnen-3-one (17,20β-P) in female Prussian carp (Carassius gibelio Bloch) at the time of their natural spawning were determined. Aroclor 1254 at doses of 0.01, 0.1, and 1 mg/kg body weight was dissolved in 500 ml of oil and was administered three times intraperitoneally or rectally to female Prussian carp every 24 h for three days. Blood samples were collected after 3 days of Aroclor 1254 administration to determine the LH and 17,20β-P concentrations using ELISA. At 6, 12, and 24 h after injection of gonadotropin-releasing hormone analogue (GnRH-A) blood samples were collected for stimulated LH secretion determination. Aroclor 1254 administered intraperitoneally (0.1 and 1 mg/kg)and rectally (0.01 and 1 mg/kg) significantly increased spontaneous LH secretion. In the case of GnRH-A-stimulated LH release, Aroclor 1254 (administered intraperitoneally only) at concentrations of 0.1 and 1 mg/kg significantly decreased gonadotropin release. The intraperitoneal injections of the lowest tested concentration of Aroclor 1254 also significantly decreased 17,20β-P secretion. The results show that Aroclor 1254 can affect the reproductive system of Prussian carp by changing the secretion of two very important hormones, LH and 17,20β-P, at the time of natural spawning.

Anna Kusumawati, Amir Noviyanto

Plant Soil Environ., 2025, 71(3):213-231 | DOI: 10.17221/648/2024-PSE

This study investigates the impact of prolonged sugarcane cultivation on the pedo-morphological characteristics and physicochemical properties of three soil types: Entisols, Inceptisols, and Vertisols, as a basis for determining the improvement step ensuring the sustainability of sugarcane production in Indonesia. Soil samples were collected from fields of sugarcane cultivated for 10, 20, and 30 years to analyse pedo-morphological and physicochemical properties. The results indicate that while Entisols and Inceptisols exhibited significant changes in soil properties with increasing cultivation duration, the pedo-morphology of Vertisols remained relatively stable. All soil types developed Ap horizons due to sugarcane cultivation, with anthropogenic practices leading to more dynamic changes in surface horizons. Extended cultivation reduced soil organic matter, N-total, and available nitrogen, while phosphorus and exchangeable cation availability were influenced by mineral composition. Notably, cation exchange capacity (CEC) decreased in Entisols and Inceptisols but increased in Vertisols. For productivity, Vertisols demonstrated the most stable and highest sugarcane productivity with long-term monoculture cultivation. There is a need for tailored sustainable soil management across different soil types and practices to mitigate soil degradation and maintain nutrient availability to ensure the sustainability of sugarcane production in Indonesia.

Plant Protect. Sci., 2025, 61(2):110-151 | DOI: 10.17221/83/2024-PPS

This article provides a review of recent studies on the extent to which the use of organic acid elicitors such as salicylic, jasmonic, humic and ascorbic acids has been successful in alleviating the exposure of Lamiaceae plants to unfavourable environmental conditions such as drought and salinity. Overall, the results concluded all organic acid elicitors enhanced the morphological and physiological characteristics of biochemical and secondary metabolite contents. These improvements have enabled plants of the Lamiaceae family to adapt to environmental stress conditions to some extent and survive, thus achieving sustainability in the production of plants of this family. It can be recommended to use salicylic acid in concentrations 0.5–2.5 mM, and it should not exceed it so as not to cause poisoning and disruption of the vital and physiological processes within the plant. In contrast, these plants have limited studies on the relationship between jasmonic acid/ascorbic acid and ascorbic acid. Since vitamins such as ascorbic acid are essential for plant metabolism and growth regulation, their effect on these plants remains unstudied at concentrations 2–10 mM under different abiotic stresses. Further research is needed to understand the impact of Nano-SA, JA, HA, ASA, and citric acid on Lamiaceae plants under various environmental stress conditions. Limited studies exist on the relationship between jasmonate/humic acid and Lamiaceae plants under abiotic stress. The Lamiaceae family needs more studies on adaptation to various environmental conditions and the toxicity of stimulants used to confront these conditions. This research contributes to improving agricultural practices in challenging environmental regions.

Modelling the hydration process of wheat grain  with layer-dependent diffusion coefficientsOriginal Paper

Bakhtiyar Ismailov, Abdushukur Urinboev, Khairulla Ismailov, Akmaljon Kuchkarov

Res. Agr. Eng., 2026, 72(1):25-40 | DOI: 10.17221/101/2025-RAE

This study develops and validates a multilayer diffusion model of wheat grain hydration that incorporates layer-dependent diffusion coefficients for bran, endosperm, and germ. The moisture transport is formulated using Fick’s law with two interface formulations: (i) classical continuity of the concentration and flux and (ii) an interlayer resistance formulation that permits concentration discontinuities. Diffusion coefficients and geometric parameters were determined experimentally; A 3D grain model (structured-light scanning, COMSOL Multiphysics) informed the computational domain. Numerical solutions combined eigenfunction expansions with finite-difference discretisation near the interfaces. Across eight winter wheat varieties, the diffusion coefficients spanned 11.6 – 20.5 × 10–12m2·s–1 (mean 16.27 ± 3.08 × 10–12m2·s–1 ). Relative to the continuity model, the resistance model reduced the early-stage endosperm over-prediction by ~ 0.6–1.0 % (absolute) and lowered the whole-grain RMSE by ~ 20–30% over 0–240 min. These results support the role of thin moisture-retaining films as active barriers and yield smooth, real-time-ready outputs suitable for the automated control of pre-milling hydration; the framework is extensible to full 3D transient simulations.

Hort. Sci. (Prague), 2026, 53(1):15-26 | DOI: 10.17221/163/2023-HORTSCI


Natural plants are abundant in their native habitats and are traditionally used to treat a variety of health conditions. The Rosa genus stands out as an important species rich in bioactive compounds. This study, conducted in Türkiye, aimed to analyse the antioxidant and phenolic profiles of methanolic extracts obtained from different parts of Rosa canina (R.c.) and Rosa pimpinelifolia (R.p.) collected in 2021 and 2022. The antioxidant activity values of R.c. collected in 2021 and 2022 were found to be between 5 102.31–46 396.36 mmol Fe(II)/100 g in ferric reducing antioxidant power (FRAP), 141.92–377.54 mg ascorbic acid equivalents (AA)/kg in total antioxidant capacity (TAC), 2.18–24.68 µg/g in 2,2-diphenyl-1-picrylhydrazyl [DPPH (EC50)] and 34.31–75.77 % in DPPH (% inhibition). Antioxidant activity of R.p. collected in 2021 and 2022 ranged from 17 258.44–71 903.20 mmol Fe(II)/100 g, 271.69–479.19 mg AA/kg, 1.02–8.32 µg/g and 50.98–85.57% for FRAP, TAC, DPPH (EC50) and DPPH (% inhibition), respectively. The R.p. extracts generally exhibited higher antioxidant activity than those of R.c. Considering the total identified phenolic compounds achieved from different plant parts of rosehip for both years, the highest values of total phenolic compounds were determined in R.c. leaves (222.08 mg/100 g) in 2021, and R.p. leaves (5 465.95 mg/100 g) in 2021.

Mango (Mangifera indica) is extremely perishable with a short shelf life that limits its marketability. Chitosan may extend mango storage by preventing moisture loss and gaseous exchange while preserving the nutritional quality. Therefore, the current study was designed to assess the effect of chitosan on the shelf life and quality of fresh-cut mangoes. Manually cubed mango was dipped into 0 (control), 10, 15, 20, 30, and 50 ppm chitosan solution in airtight jar and stored at ambient (25–28 °C) and refrigeration (4 °C) condition. Changes in various microbial, physical, and chemical characteristics were documented to evaluate the effectiveness of treatments in prolonging and sustaining the freshness and quality of mango. Treated mangoes significantly retarded growth of total mold and bacterial counts compared to the control sample in both storage conditions and found it lower under refrigeration. Likewise, chitosan also preserved various fruit quality attributes to a significant extent by retaining vitamin C, fat, titratable acidity, soluble sugar, and protein. However, the refrigerator stored mangoes have better ability to retard moisture loss and drop in sensory quality. Among the other solutions, 10 ppm chitosan solution exhibited better performance in reducing perishability of mango while maintaining prolonged shelf life and quality attributes. Overall, the findings revealed that chitosan solution at low temperature effectively preserves mango quality during storage and offers promising approach for the successful commercialisation of chitosan as a natural preserver for mango sellers and consumers to prolong shelf life.

Mexico ranks among the countries with the highest deforestation rates, increasing the demand for high-quality forest seedlings of valuable species such as Pinus pseudostrobus Lindl., which face germination limitations due to seed dormancy and low viability. Ionising radiation has emerged as an alternative pregermination treatment capable of inducing adaptive responses in plants through hormesis. This study evaluated the effects of different doses of gamma radiation (60Co) and high-energy X-rays (linear accelerator, 6 MeV) on the germination, growth, and quality of P. pseudostrobus seedlings. A total of 1 440 seeds were irradiated per radiation source with 12 doses (0–25 Gy) and sown under nursery conditions in a completely randomised design. Germination parameters, morphological traits, photosynthetic pigment content, and quality indices were analysed. With both radiation sources, low doses (0.5–1.5 Gy) significantly enhanced germination, chlorophyll content, and seedling height and diameter, while doses above 15 Gy inhibited these responses. The LD50 (median lethal dose) was estimated at 20 Gy for gamma rays and 12 Gy for X-rays, whereas GR50 (median growth reduction dose) exceeded 45 Gy in both treatments. These findings demonstrate that low radiation doses elicit a beneficial hormetic effect in P. pseudostrobus, representing a viable biotechnological approach to improve seedling production and ecological reforestation efficiency.

In the contemporary era, organisations have embraced the internet as a platform through which they disseminate information about their economic activities and their corporate social responsibility, including their environmental responsibility. Consequently, the extent to which an organisation's actions are visible on its website can be taken as an indicator of its commitment to environmental issues. The present article proposes a model for evaluating the environmental commitment of agri-food companies through the visibility of objective information on their environmental actions on their websites. The information is presented in tabular form, consisting of 33 items, and the combination of these with a predetermined weight gives an index called the Environmental Commitment Web Index (ECWI). The model was applied to all large and medium-sized Spanish wineries in 2018 and 2024. The findings indicate an improvement in the environmental commitment of these wineries, as reflected by the doubling of the ECWI during this period from 9.8 points in 2018 to 20.2 points in 2024. Nonetheless, the overwhelming majority of these wineries were regarded as exhibiting a 'very poor' environmental commitment: 94.2% in 2018 and 81.4% in 2024. It is concluded that all large and medium-sized Spanish wineries should undertake sustained endeavours to disseminate environmental initiatives on their websites.

To enhance the biomechanical database of plant root systems for soil reinforcement and erosion control in arid and semi-arid regions, and to provide a scientific basis for selecting superior native shrub and herb species in forestry and grassland measures for desertification control in central and western Inner Mongolia, this study investigated the root-soil interfacial friction characteristics of five typical native plant species – Caragana korshinskii and Hippophae rhamnoides, the semi-shrub Hedysarum mongolicum, and the perennial herbs Medicago sativa and Astragalus adsurgens – in two widely distributed non-zonal soils: loessial soil and aeolian sandy soil. Single-root pull-out tests were conducted on indoor-prepared root-soil composite samples to examine their responses to varying soil moisture levels. The results showed that within a soil moisture range of 4.6% to 20.6%, the single-root pull-out resistance and shear strength of all five species in both soil types followed a quadratic model Yax2 + bx + c (with all multiple correlation coefficients > 0.5), initially increasing and then decreasing with rising moisture content. Peak values occurred at 8.6% moisture, with consistently higher values observed in loessial soil than in aeolian sandy soil. This indicates an optimal soil moisture level for maximising root-soil interfacial friction resistance. Among the species, Hippophae rhamnoides and Medicago sativa exhibited superior pull-out performance in both soils, with Hippophae rhamnoides showing greater sensitivity to environmental variations in loessial soil. Redundancy analysis identified soil type and moisture content as key factors explaining variations in root pull-out shear strength. These findings demonstrate that mixed-species plantations, leveraging complementary root traits, can form more complex and stable root-soil structures, thereby enhancing surface soil mechanical stability. Further research is needed to elucidate the adaptive mechanisms linking plant traits, environmental conditions, and biomechanical characteristics.

Octopus (Octopus sp.) is highly perishable marine species for which efficient drying is essential to extend shelf life in tropical climates. The anatomical heterogeneity of the octopus complicates consistent drying. This study systematically evaluated the performance of a mixed solar dryer (MSD) and open solar drying (OSD) across distinct anatomical regions (head, mantle, and tentacles), with emphasis on drying kinetics and quality attributes. Five thin-layer models were applied to characterize moisture reduction, and product quality was assessed by measuring browning, protein, fat, and ash content. The MSD achieved a 20% higher temperature and 29% lower humidity, resulting in a 74% increase in drying rate relative to OSD. The Hasibuan and Daud model exhibited the highest predictive accuracy (coefficient of determination (R2) = 0.9965; root mean square error (RMSE) = 0.0168; sum of squared errors (SSE) = 0.0058). Significant interaction effects between anatomical region and drying method were observed for browning and ash content (P < 0.05), whereas protein and fat content were primarily influenced by anatomical characteristics. Overall, the MSD produced products with reduced browning and enhanced nutrient retention. These results support the implementation of MSD technology by small-scale processors to improve both drying efficiency and product quality in octopus preservation.

In the context of the modern EU bioeconomy, the use of industrial crops, particularly castor beans (Ricinus communis L.), is relevant for the production of industrial and energy products without competing with food crops. Castor oil is used for the production of biodiesel, lubricants, paints and coatings, cosmetics, and pharmaceuticals. In Ukraine, castor beans can be cultivated on low-yield soils, with seed yields ranging from 1.5 t/ha to 2.1 t/ha depending on the variety. However, the morphological features of the fruits and uneven ripening complicate the mechanisation of harvesting and seed cleaning processes. Existing equipment designed for other crops cannot be applied due to the risk of damaging the castor seeds. A design of a castor seed cleaning machine has been proposed, combining mechanical fruit shelling with the aerodynamic separation of the mixture. The machine is equipped with an eccentric crushing cone, rubber linings, a pneumatic separation channel, a cyclone, and an automated control unit. As a result of numerical modelling and experimental studies of the process of separating and cleaning castor seeds, dependencies were obtained for the productivity of the developed machine Q, power consumption P, specific energy consumption E, fraction of unshelled fruits (segments) ξf, content of the clean seed in the seed collector ψs-s depending on the distance between the reverse and crushing cones δ, rotation frequency of the crushing cone n, diameter of the feed opening Din, inclination angle of the crushing cone axis γ, and airflow velocity V. A multi-criteria optimisation method was applied to find the optimal operating modes: δ = 10.8 mm; n = 282 rpm; V = 3.6 m/s; Din = 98 mm; γ = 3.6°; β = 20.3°. The following results were achieved: E = 0.0394 MJ/kg; Q = 163.4 kg/h; P = 1 861 W; ξf = 0.099; ψs-s = 0.958. The obtained results confirm the efficiency of the proposed design for industrial implementation.

The avocado (Persea americana Mill.) is a high value fruit crop in Indonesia. This exotic commodity is affected by dieback disease, an unrecorded disease in the country that threatens the production. The objectives of the present study were to characterise the pathogen and culturable non-pathogenic fungi associated with the dieback disease of avocado plants. Fungal isolates were collected from branches of avocados showing dieback symptom in the Standard and Instrument Tropical Fruit Applied Institute (SITFAI) experimental orchards during 2022–2023. A total of 17 fungal isolates selected from 73 fungal isolates isolated from three location were characterised morphologically, molecularly, phylogenetically, and by pathogenicity tests. The fungal isolates were tested for their pathogenicity to the local variety of avocado with two stages and three replications. The identification of the fungal species was conducted on the morphological characteristics and molecular analysis obtained from the internal transcribed spacer (ITS), the 28S region of the ribosomal DNA, and translation elongation factor 1 (TEF1). The results revealed that the artificial inoculation of Avo7 and Avo3.2 isolates, identified as Lasiodiplodia theobromae, caused necrosis and wilt symptoms on the avocado seedlings. Several fungal species from the Botryosphaeriaceae, Eurotiomycetes, and Sordariomycetes groups were found alongside the pathogen responsible for causing the dieback symptoms in the avocados. The most frequently isolated genera were fast growing, Botryosphaeriaceae (58.9%), followed by Penicillium spp. (20.5%), Pestalotiopsis spp. (15.1%) and Colletotrichum spp. (5.4%). The information in this article should be used as new insights about the incidence of dieback disease caused by L. theobromae and proper management strategies against dieback disease on avocado need to be developed.

Coppice is the oldest form of systematic and sustainable use of forests, and is currently applied on about 29 million ha (about 14% of total forest land area) in Europe. It had its maximum spread in the 16th century, when an estimated 36% of all forested land in Europe was managed for coppice. Coppice forests were the most important source of fuelwood until the mid-19th century, when firewood and charcoal were substituted by alternative fuels, and the demand for construction wood increased. Consequently, coppices (both low and coppice-with-standards) started to be converted to high forests, and the process was driven by national policies and/or subsidies, which is still the situation in some European countries. During the 20th century, coppicing was abandoned in many places across Europe due to the abandonment of the countryside and population migration into cities, as well as changes in socio-economic conditions, technical advances and political restrictions. However, coppicing is still important in many European countries as the main source of firewood for the rural population, who has limited access to other sources of energy. In this context, this paper presents the most important characteristics of this complex abandonment/management/conversion picture, emphasising the pros and cons for the future of coppices across Europe.

Panax japonicus (T. Nees) C.A. Mey is a rare plant that is used in Chinese herbal medicine. Two-year-old Panax japonicus seedlings were grown in open-top chambers under ambient CO2 (aCO2), moderately (e1CO2: 550 ± 15 μmol/mol) or substantially (e2CO2: 750 ± 15 μmol/mol) elevated CO2 to study their effects on plant growth and nitrogen (N) content. After 27 days, the net photosynthetic rate (Pn) of e2CO2-treated seedlings was significantly higher (20.09%) than that of seedlings grown under aCO2. However, by day 51, the Pn of e1CO2- and e2CO2-treated seedlings was 12.87% higher and 9.57% lower, respectively, than that of seedlings grown under aCO2. On day 27, chlorophyll + b content, Rubisco activity, soluble protein and starch content of e1CO2- and e2CO2-treated seedlings showed no significant change and significant increase compared to aCO2-treated. By contrast, at 51 days, chlorophyll content, Rubisco activity, starch and N content of P. japonicus was significantly increased by moderately eCO2 condition but was significantly decreased by substantially eCO2 condition. The results suggest that exposure to moderately eCO2 was beneficial for P. japonicus growth, whereas under substantially eCO2, growth were promoted in short-term but inhibited in long-term. Owing to the temporal effect of eCO2 on P. japonicus growth, there was no significant correlation between N content and Pn of P. japonicus under eCO2.

This study investigated the effectiveness of ohmic heating (OH) for the inactivation of pectin methylesterase (PME) in passion fruit juice. PME is a heat-resistant enzyme responsible for juice cloud loss and quality deterioration during storage and is therefore commonly used as an indicator of pasteurisation efficiency. Juice samples were initially heated from 20 to 70 °C and subsequently held at 70 °C for 10 s while being subjected to different electric field strengths (20–40 V·cm–1) and frequencies ranging from 50 to 10 000 Hz. The highest PME inactivation was observed at 60 Hz, and increasing electric field strength further enhanced the inactivation effect. Based on these results, a frequency of 60 Hz and an electric field strength of 30 V·cm–1 were selected for subsequent experiments. The effects of temperature (60–90 °C) and holding time (0–90 s) on PME inactivation during OH treatment were then evaluated and compared with conventional heating (CH). OH treatment at 90 °C for 70 s resulted in approximately 90% PME inactivation, which was 10.2% higher than that achieved by CH. In addition, OH treatment caused no significant additional degradation of ascorbic acid, total polyphenols, or antioxidant activity, indicating that the applied electric field did not adversely affect these bioactive compounds. These findings demonstrate that ohmic heating is a promising and mild pasteurisation technology for fruit juice processing.

Soil salinity is a major environmental constraint that limits the growth and productivity of peanut (Arachis hypogaea L.), a legume adapted to mildly acidic soils but highly sensitive to saline–alkaline conditions. Dehydration-Responsive Element Binding (DREB) transcription factors are key regulators of plant responses to abiotic stresses. In this study, the AhDREB gene from peanut was introduced into tobacco (Nicotiana tabacum) to examine its functional role under salt stress. The transgenic lines (L32.2 and L37.2) exhibited strong induction of AhDREB expression upon exposure to 150 and 250 mM NaCl, with transcript levels increasing up to 2.34-fold compared with untreated controls (< 0.001). Quantitative RT-PCR analysis revealed that AhDREB enhanced the transcription of two osmolyte-related genes, NtP5CS and NtSUSY. Under saline conditions, the expression of these genes was 1.20–1.89-fold higher in transgenic lines than in wild-type (WT) plants and 4.74–7.66-fold higher than in non-stress conditions (P < 0.001). Consistently, both lines accumulated greater amounts of proline and soluble sugars, showing 2.09–2.30-fold and 2.40–4.70-fold increases, respectively, compared with the WT. Relative to non-stress conditions, proline and sugar contents increased by 3.59–5.47 fold and 3.75–7.65-fold, respectively. Line L37.2 accumulated higher proline levels, whereas L32.2 exhibited greater sugar content, indicating distinct osmolyte regulation patterns. Overall, the AhDREB gene enhances salt tolerance in tobacco by transcriptionally activating osmolyte biosynthetic pathways and improving cellular osmotic adjustment, providing molecular evidence for its potential application in developing stress-tolerant peanut cultivars.

Czech J. Food Sci., 2026, 44(1):52-61 | DOI: 10.17221/48/2025-CJFS

Dioscorea species possess valuable properties that make them suitable for use in food production. This study characterised doughs made with flours from two species of Dioscorea by evaluating their nutritional, rheological and textural properties for use in baking. Dioscorea composita flour had a higher crude fibre content (1.5% ± 0.11), while Dioscorea bulbifera flour exhibited higher antioxidant content [930.5mg GAE · (100g)–1 dry matter] and better protein digestibility (89.06% ± 0.7%). Wheat flour was substituted with Dioscorea flour (0–30%) to make composite doughs. Doughs containing D. composita exhibited superior biaxial extensibility (41.22 ± 11.9mm at 20% substitution), compared to the control (21.4 ± 2.7mm), indicating their potential for use in bread production. Meanwhile, doughs containing 20% or more D. bulbifera flour were more suitable for products such as biscuits or pitta bread. However, all composite doughs were harder to handle, likely due to gluten dilution and component interactions, regardless of the Dioscorea species used. Therefore, the Dioscorea species used in this study could be considered promising candidates for inclusion in suitable bakery products.
