Immobilised Aspergillus niger lipase synthesises sn-1,3-dioleoyl-2-palmitoylglycerolOriginal PaperShanhui Chen, Renbin Liu, Dong Wang, Shiyou Li, Zhirong YangCzech J. Food Sci., 2025, 43(4):291-299 | DOI: 10.17221/143/2024-CJFS sn-1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a structural triglyceride with a specific distribution of fatty acids, which is an important component of breast milk fat and which can better promote the absorption of minerals and energy in infants. In this study, a lab-made immobilised Aspergillus niger lipase (IM-ANL), which is more economical than a commercial lipase, was used for hydrolysis to produce free fatty acids (FFA) and acidolysis interesterification to produce OPO. The enzyme was used for multiple purposes, reducing the cost of enzymatic production. The optimum conditions for hydrolysis were determined by experiments: the amount of IM-ANL enzyme dosage was 3%, the reaction temperature was 45 °C, and the reaction time was 48 h. The optimum conditions for acidolysis interesterification were as follows: the amount of IM-ANL enzyme dosage was 4%, the molar ratio of tripalmitin to oleic acid was 1 : 8, the reaction temperature was 55 °C, and the reaction time was 3 h. In this study, economical palm stearin and high oleic acid sunflower seed oil were selected as reaction raw materials, and the reaction temperature was moderate, the safety risk was low, the energy consumption was reduced, the process was more economical, and the economic value of high oleic acid vegetable oil was improved, which was conducive to the further promotion of OPO production. |
Combined application of biochar and phosphorus influenced maize production and soil properties in the Yellow River Delta: a comparison between contrasting weather conditionsOriginal PaperXiaoqi Tang, Chunming Jiang, Hongjie Li, Jing Tian, Dawei Li, Xuan Zhang, Xiuli Ge, Xia Liu, Wenjun Gao, Guoli Liu, Wenjuan LiPlant Soil Environ., 2025, 71(8):581-594 | DOI: 10.17221/268/2025-PSE The Yellow River Delta, an important area of reserved arable land resources in China, is faced with the problem of crop productivity being typically limited by low soil quality. Developing techniques that raised crop yield without environmental damage was critically needed. To date, the knowledge about the joint impacts of biochar (C) and phosphorus (P) addition on soil properties and maize production under different weather conditions in this area is seriously lacking. Consequently, a full factorial field experiment including three biochar intensities (0 (C0), 5 000 (C1), and 10 000 (C2) kg/ha), three phosphorus fertilisation levels (0 (P0), 60 (P1), and 120 (P2) kg P/ha), and their combinations was conducted in Binzhou, Shandong province of China from 2021 to 2022. Compared to 2022, the maize yield was dramatically reduced in 2021 (with a 35% mean decrease) due to excessive rainfall in the maize reproductive growth stage (P < 0.01). C addition caused greater proportions and contributions of dry matter and nutrient remobilisation from pre-anthesis vegetation organs to grain. Subsequently, maize yield was much more promoted in 2021 (23%) than in 2022 (5%) by adding C, in which the discrepancies between C1 and C2 were relatively small and insignificant. On the other hand, these corresponding effects of P and C × P were relatively modest. From the soil perspective, soil physical (hydraulic conductivity (Ks) and bulk density) and chemical properties (soil organic carbon, total N, and soil available N) were significantly improved by C addition (P < 0.01). More importantly, we detected negative interactions of C × P on soil available P and phosphorus activation coefficient (P < 0.01), as soil available P was lowered with more input of C and P together (particularly under P2 series). The two-year outcomes suggested that C addition could enhance maize growth and ensure crop yield stability. Still, the combined incorporation of this kind of C and P (especially for C2P2) was not recommended in the saline-alkali land. The present study delivered useful insight into the rational utilisation of C and P fertilisers in the Yellow River Delta. |
Rural e-commerce and agricultural total factor productivity: Evidence from ChinaOriginal PaperJialong Zheng, Xintong Liang, Junkai Ma, Guangsi LiAgric. Econ. - Czech, 2025, 71(10):550-563 | DOI: 10.17221/289/2024-AGRICECON Employing the Comprehensive Demonstration of E-commerce in Rural Areas (CDERA) policy as a quasi-natural experiment, this paper explores the impact of rural e-commerce development on agricultural total factor productivity (ATFP) and its underlying mechanisms, using a difference-in-differences model. The analysis utilises panel data from 1 495 counties in China from 2001 to 2021. The findings indicate that the CDERA policy implementation enhanced ATFP in treated counties by approximately 1.6 percentage points compared to control counties, other factors being equal. Mechanism analysis further reveals that the CDERA policy enhances ATFP by improving agricultural technological efficiency and fostering agricultural industrial development. This study highlights the significant role of CDERA policy in enhancing agricultural productivity in China and offers policy insights for advancing rural e-commerce and promoting sustainable agricultural development. |
Ginger essential oil-infused pectin-alginate films for extending sliced bread shelf lifeOriginal PaperNguyen Hong Khoi Nguyen, Nam Quoc Tran, Thuan Huynh Dinh Nguyen, Quyen Phuong HuynhCzech J. Food Sci., 2025, 43(6):438-449 | DOI: 10.17221/24/2025-CJFS This study examines composite films made from pectin and alginate, enhanced with ginger essential oil (GEO) at 0, 0.5, 1, and 1.5% concentration. The films were analysed for their structure, physical properties, antioxidant and antibacterial activities, and effectiveness in preserving sliced bread over 0, 2, 4, 6, and 8 days. The outcomes presented that incorporating GEO upgraded pectin-alginate films' properties. SEM images revealed increased essential oil distribution on the film surface with higher GEO concentrations, indicating good compatibility. Higher GEO concentrations enhanced the films' abilities to scavenge free radicals DPPH, 2,2-diphenyl-1-picrylhydrazyl; and ABTS, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and inhibit bacteria (Listeria monocytogenes and Escherichia coli). Furthermore, increasing GEO concentrations in the films helped maintain key quality attributes of sliced bread, such as moisture content, water activity, microbial counts, and firmness. Films with 1.0 and 1.5% GEO concentrations were the most effective in preserving bread, potentially inhibiting mould formation and maintaining sensory properties over the 8-day storage period. This study demonstrates that pectin-alginate films supplemented with GEO at 1 and 1.5% concentration are suitable for storing sliced bread. |
Decision tree analysis of the prospects of organic food: Evidence from China and HungaryOriginal PaperYue Wu, Andrea Tick, Katalin Takács-GyörgyCzech J. Food Sci., 2025, 43(6):450-461 | DOI: 10.17221/205/2024-CJFS With the growing population, increasing income, and high-speed lifestyle, people pay more attention to a healthy diet and nutritional food. Organic food, also regarded as healthy, sustainable, or eco-friendly eating, has gained global popularity. This trend has been particularly amplified by the COVID-19 pandemic, leading to a surge in demand for nutritious foods worldwide. Organic food originated in Europe, with the highest development globally. Its progress varies by country. China's organic food industry began decades ago, growing rapidly. As globalisation advances and China's economy accelerates, it is valuable to examine the organic food industries in Hungary and China. In order to understand the willingness of consumers to buy organic food, we conducted a survey for a month in 2021 from 581 respondents in Hungary (185), China (374), and other countries, compared the respondents' demographic data, organic food consumption and their buying willingness and attitude to recommend organic food to other consumers. The decision tree analysis was deployed to analyse the statistical data via SPSS software. It showed that organic food has a positive demand in both Hungary and China, but some purchase habits are different in these two countries. |

Impact of microencapsulation and milk matrix on Lactobacillus acidophilus survivalin yoghurt-based icecreamsOriginal PaperFeray İnci Maden, Salih ÖzdemirCzech J. Food Sci., 2026, 44(3):181-191 | DOI: 10.17221/107/2025-CJFS This study examined the effects of milk origin (cow versus buffalo), probiotic delivery form (free cells versus alginate-encapsulated Lactobacillus acidophilus ATCC 4356), and inulin supplementation on microbial viability, physicochemical properties, and melting behaviour of yoghurt ice cream over a 60 day storage period. Ten formulations were evaluated on days 1, 15, 30, and 60 for total and probiotic counts, yeast and mould levels, pH, titratable acidity, drip time, viscosity (measured at 30 and 50 rpm), and overrun. Buffalo milk samples containing encapsulated probiotics and inulin showed the highest Lactobacillus acidophilus counts (reaching 5.97 log CFU·g–1), the greatest resistance to melting (first drip: 97.14 min), the highest viscosity (20.166 Pa.s at 30 rpm), and the highest overrun (34.77%), whereas cow milk controls exhibited the lowest microbial survival and melting performance. Encapsulation markedly improved probiotic stability; in most encapsulated samples, yeast and mould counts remained below 2.00 log CFU·g–1 after 30 days, and this was accompanied by higher pH values (maximum 4.99 ± 0.04) and more controlled titratable acidity levels (0.57–0.87%). These findings indicate that alginate microencapsulation, particularly within buffalo milk matrices, effectively enhances probiotic viability and the functional quality of frozen dairy products. |

Evaluation of three-phase centrifugal separator machine (Tricanter) for olive oil extractionOriginal PaperAshkan Shokrian, Qiaorui Si, Peng WangCzech J. Food Sci., 2022, 40(3):221-228 | DOI: 10.17221/278/2021-CJFS One of the most important machines in the olive oil extraction line is the horizontal three-phase centrifugal separator machine or Tricanter. The purpose of this paper is to evaluate the machine designed on the basis of Tricanter and to evaluate the quality of extracted olive oil. For this purpose, four different olive cultivars from Gilan Province in Iran were used. In this research the rotational speed of the Tricanter machine was tested at three levels of 2 500, 3 000, and 3 500 rpm and the content of water added to olive paste was used at three levels of 10, 20, and 30% of the paste mass. Peroxide value (PV) and percentage of acidity were measured for oil extracted from all four olive cultivars. The results of the analysis of variance (ANOVA) test showed that rotational speed and the content of added water had an effect on the acidity and PV for all samples of olive cultivars. The measured values showed that the best speed for the Tricanter machine is 3 500 rpm. At this rotational speed, the peroxide and acidity values are lower than the standard values. |
Effects of ozonation on water quality and pikeperch (Sander lucioperca) performance in a recirculating aquaculture systemOriginal PaperJitka Kolářová, Jiří Křišťan, Oleksandr Malinovskyi, Josef Velíšek, Alžběta Stará, Samad Rahimnejad, Tomáš PolicarCzech J. Anim. Sci., 2021, 66(9):381-390 | DOI: 10.17221/54/2021-CJAS The aim of this study was to examine the effects of ozonation on the water quality, and growth, blood biochemistry, antioxidant capacity and survival of pikeperch (Sander lucioperca) reared in a recirculation aquaculture system for 30 weeks. A group without ozone treatment was used as a control. The ozone application led to a significant reduction of the water chemical oxygen demand, biological oxygen demand and unsuspended solids concentration. The results revealed that an ozone treatment as a water treatment method has a positive influence on the intensive culture of pikeperch ensuring a higher survival rate (77%) compared to the non-treated control group (67.2%). Moreover, the ozonation prevented fin damage to a large extent and reduced the prevalence of an Ichthyophthirius multifiliis infection. Furthermore, the ozone application led to a reduction in the thiobarbituric acid reactive substance level and enhanced the superoxide dismutase activity in the fish gills. However, the effect of ozonation was null on the plasma biochemical parameters. Overall, these findings suggest that an ozone treatment, using adequate technological equipment to destroy the residual ozone, improves the water quality and protects pikeperch against any possible infection and fin damage in a recirculation aquaculture system. |
Prenatal effects of red and blue light on physiological and behavioural parameters of broiler chickensOriginal PaperAngelika Drozdová, Zuzana Kaňková, Boris Bilčík, Michal ZemanCzech J. Anim. Sci., 2021, 66(10):412-419 | DOI: 10.17221/80/2021-CJAS Light during incubation can influence embryonic and postembryonic development of chickens, but the underlying mechanisms are poorly understood. Previous studies have demonstrated that red and blue lights during incubation had opposite effects on the development of embryonic melatonin biosynthesis; red light results in the highest and blue light in the lowest amplitude of the daily rhythm. Therefore, in this study, we investigated if exposure to monochromatic red (632 nm) and blue (463 nm) light during incubation can differently influence growth, selected biochemical (glucose, cholesterol, triacylglycerols) and endocrine (corticosterone and thyroid hormones) traits and behavioural parameters during postembryonic development in broiler chickens. For analysis, we used 10 and 11 hatchlings incubated in red and blue light, respectively and 10 birds per each group (six males and four females) in 3-weeks-old broilers. During the rapid growth phase (days 18, 20 and 21 of age), higher body weight was recorded in broilers incubated under red compared to blue light, whereas endocrine and metabolic traits did not differ between the treatments. The improved growth rate was related to behavioural traits, mainly because chickens incubated in red light exhibited more passive (resting, standing, preening, dust bathing) and less active behaviours (walking, foraging, fighting, wing-flapping) than the blue-light incubated birds. The time spent for eating and drinking and the results of the tonic immobility test did not differ between both groups. Our results suggest that red and blue monochromatic light during incubation can differently program the postembryonic development of broilers, with possible consequences for their growth and welfare. |
Comparison of starch digestibility methods for extruded wheat grains (Triticum aestivum L.)Original PaperDana Homolková, Vladimír Plachý, Anna Maňourová, Michal Kaválek, Václav Dvořáček, Boris Hučko, Milan Marounek, Ivo DoskočilCzech J. Anim. Sci., 2021, 66(10):420-427 | DOI: 10.17221/56/2021-CJAS This study compared different methods of determining starch digestibility (in vivo vs in vitro) in wheat grains and evaluated the influence of extrusion on digestibility. In vivo starch digestibility was determined in broiler chickens by calculating the residual starch content in their ilea and the digestibility using a chromium oxide indicator. In vitro digestibility was examined using pepsin and pancreatin. During in vivo testing, the highest digestibility coefficient (DC) was achieved by the Bonanza variety in its extruded form (91.19 ± 0.40%). In contrast, the lowest DC was achieved by the Tobak variety in its non-extruded form (81.45 ± 1.92%). Generally, a higher DC was observed in vivo for extruded forms of wheat. During in vitro testing, the highest DC was achieved by the Stefii variety in its non-extruded form (96.10 ± 0.55%), whereas the lowest DC was observed in the Yetti variety in its extruded form (49.72 ± 0.41%). Overall, the in vitro experiments did not exhibit significant differences between extruded and non-extruded forms of wheat. Linear regression analysis showed a strong relationship (r2 = 0.860; 85.98%) between in vivo- and in vitro-derived DC values in all wheat varieties, both in extruded and non-extruded forms. The study showed that in vivo testing is a suitable method for the determination and control of starch levels in extruded materials. However, despite the accuracy of this technique, it is also very demanding in terms of time, space, equipment, and methodological knowledge. Therefore, based on the strong correlation between the in vivo and in vitro assays, we recommend in vitro digestibility testing as a preferable alternative. |
Responses of soil-inhabiting mesostigmatid mites to deforestation and disturbance in oak (Quercus brontii) forests of southwestern IranOriginal PaperAli Bagheri-Kordeshami, Jahangir Khajehali, Farshid Nourbakhsh, Masoud M. ArdestaniJ. For. Sci., 2021, 67(12):562-569 | DOI: 10.17221/54/2021-JFS The impacts of deforestation on edaphic mesostigmatid mites were investigated in oak forests of Lordegan, southwestern Iran, from April to October. A total of twenty-one species belonging to eighteen genera and ten families were collected and identified. The Shannon-Wiener, Simpson, Jaccard's and Margalef biodiversity indices were used for data analyses. Among the collected species, Antennoseius bacatus with 29% and Sessilunchus hungaricus with 16% relative abundance were the most abundant and dominant species in human-disturbed and natural forests, respectively. The estimated values were higher in natural oak forest than in disturbed and cultivated habitat. Significant differences were observed in soil nitrogen content and soil organic carbon between the two habitats, but not in pH values. Significant effects of sampling time and habitat were found on all four indices, but the effect of their interactions on these indices was not significant. It can be concluded that the changes in soil quality that resulted from deforestation may have a major role in reducing the soil mite density and related diversity indices in disturbed forests. |
Comparison of soil organic matter composition under different land uses by DRIFT spectroscopyOriginal PaperSaven Thai, Lenka Pavlů, Václav Tejnecký, Petra Vokurková, Shahin Nozari, Luboš BorůvkaPlant Soil Environ., 2021, 67(5):255-263 | DOI: 10.17221/11/2021-PSE The study aimed to estimate and characterise soil organic matter under different land uses (cropland, grassland, and forest) and soil depths. The soil organic matter composition of the soil was assessed by diffuse reflectance infrared spectroscopy (DRIFT). Humic and fulvic acids (HAs, FAs) were extracted from soils and their compositions were evaluated by DRIFT. Low molecular mass organic acids content was also measured. Our result revealed that the largest differences of the spectra in the composition of organic matter were observed in the upper parts of the soil profile. The forest soil spectra had more intense aliphatic bands, carboxylic, and CH bands than spectra of grassland and cropland soils. The difference of HAs spectra was at 3 010 to 2 800/cm where the most intensive aliphatic bands were in forest soil HAs, followed by grassland and cropland soil HAs. The grassland topsoil FAs spectrum differs most from the other land uses. It has lower peaks around 1 660-1 600/cm and 1 200/cm than cropland and forest. The concentration of low molecular mass organic acid (LMMOA) was the highest in the forest soil and the most abundant acid was citrate. |
Soil physical properties and crop status under cattle manure and Z'Fix in Haplic ChernozemOriginal PaperVáclav Novák, Petr Šařec, Kateřina Křížová, Petr Novák, Oldřich LátalPlant Soil Environ., 2021, 67(7):390-398 | DOI: 10.17221/159/2021-PSE A three-year experiment was conducted to investigate the effect of Z'Fix on soil physical properties and crop status. Z'Fix is an agent recommended as an addition to animal bedding to prolong its function and to lower ammonia emissions in stables. Concurrently, a positive effect on organic matter transformation in resulting manure is claimed. The experiment involved control, farmyard manure (FYM), and farmyard manure with Z'Fix (FYM_ZF) as variants. In-field sampling was conducted for cone index, water infiltration and implement a unit draft, where the latter two showed significant differences in favour of FYM_ZF. Also, concerning crop yields, FYM_ZF consistently attained the highest values, followed by FYM throughout all three seasons. Furthermore, remotely sensed data were analysed to describe crop status via normalised difference vegetation index where significant differences were found across all variants. Based on the study, FYM_ZF demonstrated positive effects both on soil properties and crop conditions. |
Lead immobilisation in mining contaminated soil using biochar and ash from sugarcaneOriginal PaperDaojarus Ketrot, Worachart WisawapipatPlant Soil Environ., 2021, 67(8):474-481 | DOI: 10.17221/57/2021-PSE Immobilisation of lead (Pb) and toxic elements in contaminated soils is of importance due to their persistence in the environment. Herein, we investigated the effects of sugarcane filter cake biochar (SFCB) and sugarcane bagasse ash (SBA) on the extractability of Pb and some toxic and potentially toxic elements (As, Cd, Cu, and Zn) in polluted mine soil samples from Lower Klity Creek, Thailand. The soil was equilibrated with the SFCB and SBA at the respective rates of 0, 1, and 5% (w/w) for 120 days at field capacity. The results revealed that both SFCB and SBA materials significantly (P < 0.05) decreased Pb extractability in the studied soil, and it stabilised after 56 days of incubation. At 120 days, the SFCB and SBA application at the rates of 5% SFCB, 5% SBA, 1% SFCB, and 1% SBA decreased the extractable Pb contents by 50.35, 40.81, 29.42, and 19.27%, respectively, compared to unamended soil. The SFCB and SBA materials also improved soil chemical properties by increasing the soil pH, available phosphorus, and extractable sulfur. At 5%, SFCB decreased As extractability and increased organic carbon in the studied soil. The Zn availability in the studied soil was also improved by SFCB and SBA addition. This study highlights the potential use of biochar and ash from the sugarcane industry to stabilise Pb and As in contaminated soils. |
Phytoaccumulation of heavy metals in native plants growing on soils in the Spreča river valley, Bosnia and HerzegovinaOriginal PaperSenad Murtić, Ćerima Zahirović, Hamdija Čivić, Emina Sijahović, Josip Jurković, Jasna Avdić, Emir Šahinović, Adnana PodrugPlant Soil Environ., 2021, 67(9):533-540 | DOI: 10.17221/253/2021-PSE This study evaluated the phytoremediation potential of eight native plant species on heavy metal polluted soils along the Spreča river valley (the northeast region of Bosnia and Herzegovina). Plants selected for screening were: ryegrass (Lolium perenne L.), common nettle (Urtica dioica L.), mugwort (Artemisia vulgaris L.), wild mint (Mentha arvensis L.), white clover (Trifolium repens L.), alfalfa (Medicago sativa L.), dwarf nettle (Urtica urens L.) and yarrow (Achillea millefolium L.). All aboveground parts of selected native plants and their associated soil samples were collected and analysed for total concentration of Ni, Cr, Cd, Pb, Zn and Cu. The bioaccumulation factor for each element was also calculated. The levels of Cr (90.9-171.1 mg/kg) and Ni (80.1-390.5 mg/kg) in the studied soil plots were generally higher than limits prescribed by European standards, indicating that the soils in the Spreča river valley are polluted by Cr and Ni. Among the eight screened plant species, no hyperaccumulators for toxic heavy metals Ni, Cr, Cd and Pb were identified. However, the concentrations of toxic heavy metals in the above-ground parts of Artemisia vulgaris L. and Trifolium repens L. were significantly higher than in the other studied plants, indicating that both plant species are useful for heavy metal removal. |
Agronomic bio-fortification of iron, zinc and selenium enhance growth, quality and uptake of different sorghum accessionsOriginal PaperMuhammad Tamoor Qureshi, Muhammad Faizan Ahmad, Nasir Iqbal, Hasnain Waheed, Sajad Hussain, Marián Brestič, Adeel Anjum, Ijaz Rasool NoorkaPlant Soil Environ., 2021, 67(10):549-557 | DOI: 10.17221/137/2021-PSE Agronomic bio-fortification is one of the main approaches for mitigation of micronutrient shortage in human populations and endorses sustainable production of food and feed. Studies related to agronomic bio-fortification of crops are mainly focused on single or rarely two micronutrients application, and no attempt has made to study the combined effect of zinc (Zn), iron (Fe) and selenium (Se) on forage sorghum. Therefore, this research was accomplished to evaluate the effect of Zn, Fe and Se bio-fortification on diverse sorghum accessions. The field experiments were conducted in a randomised complete block design with a split-plot arrangement. The treatments comprised of Zn (10 mg/L as ZnSO4∙5H2O), Fe (7 mg/L as FeSO4∙7H2O), Se (3 mg/L as SeSO4) and CK (control) were applied to five sorghum accessions: G1 (Y-16), G2 (YSH-166), G3 (YSH-134), G4 (YSS-98) and G5 (YSH-132). According to our results, the sorghum accession G5 showed superiority over all other accessions and produced maximum values of all growth and quality traits except grains number per panicle and 1 000-grain weight. All applied micronutrients (Zn, Fe and Se) enhanced the growth, quality and uptake of nutrients in sorghum accessions. However, Se recorded the highest plant height, stem diameter, 1 000-grain weight and Zn produced the maximum protein, oil and starch contents. Conclusively, it can be concluded that G5 with Se must be used to achieve the optimum values of agronomic traits, while G5 with Zn found more effective to improve the quality traits of sorghum. |
Clinical and immunohistochemical findings of splenic mast cell tumour in a cat: A case reportCase ReportS Lee, MS Kang, Y Jeong, Y Kim, HH Kwak, EW Choi, S Choi, I Park, JY Chung, JH Choi, JO AhnVet Med - Czech, 2021, 66(11):498-502 | DOI: 10.17221/11/2021-VETMED A 6-year-old, spayed, female, domestic shorthair cat presented with a 4-month history of chronic intermittent vomiting and anorexia. The haematologic results indicated moderate anaemia and a circulating mast cell population. The abdominal radiography revealed a markedly enlarged spleen. The cytological analysis of the spleen showed a uniform population of mast cells, and a diagnosis of systemic mastocytosis (splenic mast cell tumour with mastocytaemia) was made. This diagnosis was subsequently confirmed by the histopathological examination of the spleen. The immunohistochemistry for KIT showed KIT pattern II (focal cytoplasmic expression). A splenectomy and chemotherapy with vinblastine and prednisolone resulted in remission of the anaemia and other clinical signs. This case report highlights the importance of cytological evaluations of peripheral blood smears and/or aspirates of enlarged spleens for diagnosing splenic mast cell tumours and for quickly initiating the appropriate treatment. |
Eco-friendly synthesis of ZnO nanoparticles for improved pectin/chitosan hydrogels with antibacterial activityOriginal PaperShirin Gull, Huma Umbreen, Mahr Un Nisa, Abid Rashid[Ahead of Print]CAAS Agricultural Journals, X:X | DOI: 10.17221/159/2025-CJFS The core objective of the present study was to develop a novel nanocomposite pectin/chitosan hydrogel based on green-synthesised zinc oxide nanoparticles (ZnO NPs-L). For this purpose, zinc oxide nanoparticles were prepared by the solution casting method, using extract from aloe vera leaves, and were incorporated into pectin/chitosan hydrogels (0, 10, and 20%). The nanoparticles were analysed using scanning electron microscopy, X-ray diffraction, UV-Vis, and FTIR (Fourier transform infrared) spectroscopy. Moreover, the hydrogels were evaluated through FTIR, scanning electronic microscopy, atomic force microscopy, gel fraction, contact angle measurements, swelling ratio, investigations of thermal stability, mechanical strength and antibacterial activity. The structural heterogeneity and surface roughness of the hydrogel were evidenced by SEM analysis. The results showed that incorporation of ZnO NPs-L into hydrogel enhanced gel fraction to > 65%, surface wettability to > 64°, tensile strength to > 5.8 MPa, and swelling ratio to > 4 140 in a dose-dependent manner. Further, ZnO NPs-L (20 mg) loaded hydrogels exhibited the highest zone of inhibition against Escherichia coli (> 13 mm) and Staphylococcus aureus (> 12 mm). The findings suggested that pectin/chitosan/ZnO NPs-L hydrogels have appropriate mechanical flexibility, swelling behaviour and antibacterial activities, which are required for their effective use in the biomedical and agricultural sectors. |
Net blotch (Pyrenophora teres Drechsler): An increasingly significant threat to barley productionReviewAndrija Tomić, Vojislav Trkulja, Slavica Matić, Nenad Trkulja, Renata Iličić, Marco Scortichini, Tatjana Popović MilovanovićPlant Protect. Sci., 2024, 60(1):1-30 | DOI: 10.17221/122/2023-PPS Pyrenophora teres is a pathogen causing a net blotch disease in cultivated barley, which is present worldwide and can thus significantly reduce barley yields. This fungus also infects wild barley and other plants of the Hordeum genus, as well as barley grass, wheat, oats and plants from various genera, including Agropyron, Bromus, Elymus, Hordelymus and Stipa. Based on the symptoms it causes on the infected barley plants, the pathogen can be divided into two forms: P. teres f. teres, which causes net-like symptoms, and P. teres f. maculata, which causes blotchy symptoms. Infected seeds, stubble and plant debris, and volunteer and weed plants represent primary sources of pathogen inoculum. During the growing season, the pathogen enters a sexual stage, developing pseudothecia with asci and ascospores. This is followed by an asexual stage, during which conidiophores with conidia are formed. The conidial (anamorphic) stage is much more common, whereby conidia is a source of inoculum for secondary infection during the barley growing season. The first symptoms appear at the end of winter and the beginning of spring, often during the tilling phase. The most characteristic symptoms form on barley leaves. Frequently, symptoms of the net form can be mistaken for other diseases occurring on barley, making molecular analysis essential for accurate detection of P. teres, its forms, mating types and hybrids. Current net blotch control measures are based on the combined application of cultural, chemical and biological control methods and the selection of resistant varieties. |

Chemical forest amelioration: Experience from the Czech Republic and other selected countries – A reviewReviewMartin Baláš, Ivan Kuneš, Vilém Podrázský, Josef Gallo, František LopotJ. For. Sci., 2024, 70(3):103-121 | DOI: 10.17221/72/2023-JFS This review article summarises the results of research on forest liming, fertilisation, nutrition flows and cycles in selected European and other countries. The presented studies mostly deal with assessing the effect of liming and fertilisation applied during planting or shortly after planting. The sporadic studies on fertilisation in older stands are also presented. The application of crushed limestone, dolomite or other alkaline rocks or their mixtures is usually used to improve the soil conditions on a large area through the adjustment of soil acidity and to supply any deficient elements, especially calcium and magnesium. These amendments are typically used on naturally nutrient-poor soils or as a curative technique to neutralise the soil chemistry affected by anthropogenic acidification. Artificial fertilisers are usually applied on small spots to individual trees on the surface of the soil shortly after planting or into a planting hole during planting. The purpose is to give some initial support to young trees to better overcome the post-planting shock and to accelerate the height growth. Less frequently, artificial fertilisers are used on large areas of forest stands for the purpose of increasing stem growth. The methods and the extent of forest fertilisation substantially vary in individual countries and different time periods. |
An overview and current progress of gibberellic acid-mediated abiotic stress alleviation in plantsReviewMd. Asif Mahamud, Shahin Imran, Newton Chandra Paul, Rakibul Hasan Md. Rabbi, Noushin Jahan, Prosenjit Sarker, Md. Najmol Hoque, Mousumi Jahan SumiPlant Soil Environ., 2025, 71(7):453-479 | DOI: 10.17221/137/2025-PSE Abiotic stressors are the main barriers to successful crop production in this era. The balance of redox and metabolic activities in plants is negatively impacted by abiotic stresses, which ultimately limit the plants’ capacity to grow and develop. The phytohormones are tiny molecules that control how plants grow and develop, as well as how they react to alterations in their environment. Phytohormone, gibberellic acid (GA) has been proven in a number of recent research to increase plants’ ability to withstand abiotic stress. By regulating numerous physio-biochemical and molecular processes, GA plays a crucial part in reducing the perturbations caused by abiotic stresses in plants. Recent findings have shown that GA controls the activity of antioxidant enzymes, stress-responsive genes, photosynthetic machinery, and reduced oxidative damage. Besides, GA has been involved in cross-talk with other phytohormones to regulate abiotic stress in plants. This review summarises the current research on the application of GA and discusses how GA might support crop growth and production in adverse conditions. The interaction of GA with other phytohormones, potential mechanisms for reducing abiotic stress in plants, the disadvantages of employing GA, and its promise for the future are also covered in this review. |
Mammary neoplasms in female dogs: Clinical, diagnostic and therapeutic aspectsReviewJR Rueda, CD Porto, RP Franco, IB da Costa, LMC Bueno, RJS Girio, FFR Manhoso, PCS Bueno, CSF RepettiVet Med - Czech, 2024, 69(4):99-114 | DOI: 10.17221/4/2024-VETMED With the increase in the life expectancy of domestic animals and their increasingly affectionate relationship with their owners, it is possible to observe an increase in cases of neoplasms in these animals. Mammary neoplasia mainly affects older females who have not been castrated, due to hormonal dependence for the development of the tumour. The main form of treatment is surgery. This study aims to carry out an updated review on mammary neoplasms in female dogs covering the anatomy, physiology, prevalence, causes, diagnoses, treatments, prevention and prognosis, based on scientific articles by renowned researchers. |

Unravelling population structure and marker trait association using SSR markers among the identified drought tolerant rice landraces (Oryza sativa L.)Original PaperShanmugam Manju Devi, John Amalraj Joel, Muthurajan Raveendran, Ramamoorthy Pushpam, Sengalan Muthuramu, Raman Pushpa, N. Sritharan, Periyasamy Prasanna, Ramalingam SureshCzech J. Genet. Plant Breed., 2025, 61(1):1-22 | DOI: 10.17221/12/2024-CJGPB With climate change, plants face numerous stresses, notably drought for rice cultivation. Improving rice drought tolerance is vital for sustainable production in water-scarce regions. Identification of drought tolerant genotypes at the seedling stage of the crop contributes to build a climate resilient genotype during the period of water scarcity and under challenging environmental conditions. Hence, polyethylene glycol-6000 (PEG-6000) induced drought conditions could be used for testing the drought tolerance in rice at an earlier stage of the crop. Optimization of PEG-6000 concentration for screening index at -6 bar was done using three drought-tolerant and two drought-susceptible check varieties based on probit analysis. Subsequently, 100 rice landraces underwent PEG-6000 induced drought screening at –6 bar and a total of 32 genotypes were selected as tolerant. After 14 days of treatment, the nine observations viz. germination %, root length (cm), shoot length (cm), number of secondary roots, fresh weight (g), dry weight (g), shoot/root ratio, root/shoot ratio and vigour index were recorded. Variance analysis, revealing significant genetic variation among genotypes for all studied traits, indicating genetic variability. Post hoc analysis confirmed notable variation among treatments. Principal component analysis revealed three components, with the first three accounting for 88.89% of total variability. With respect to the biplot, the ten genotypes viz., IRGC109, IRGC403, IRGC448, IRGC461, IRGC466, IRGC486, IRGC508, IRGC518, IRGC527 and IRGC535 are the seedling stage drought tolerant genotypes based on shoot length, number of secondary roots and vigour index. Population structure classified the accessions into two subpopulations, reflecting diversity. The allele frequency divergence is 0.095 which is a measure of fixation index revealing that the moderate divergence is not extremely pronounced. Genetic diversity, assessed through 26 SSR markers selected from drought tolerant QTLs and markers related to vigour index, exhibited 100% polymorphism with 115 alleles and an average PIC value of 0.61 per primer. Shannon index varied between 0.34 (RM212) and 1.96 (RM252), averaging 1.18. Six SSR markers viz., RM246, RM302, RM252, RM219, RM251, and RM486 were associated with the six key traits viz., shoot length, root length, number of secondary roots, dry weight, shoot/root ratio, and root/shoot ratio respectively offering valuable resources for selecting drought-tolerant accessions as it provides the first step in the selection of genotypes based on the key traits. |
