Boris Rilak, Ivan Glišić, Milan Lukić, Tomo Milošević, Jelena Tomić, Mira Milinković

Hort. Sci. (Prague), 2023, 50(4):262-274 | DOI: 10.17221/127/2022-HORTSCI

Effect of pre-harvest calcium chloride (CaCl2) treatment on fruit quality attributes of three apple cultivars (‘Golden Delicious Reinders®’, ‘Granny Smith’ and ‘Red Chief’) at harvest and after two and four months of cold storage during two consecutive years was studied. Trees were sprayed four times starting from the beginning of June at 20-day intervals. After harvest, fruits were stored in a regular atmosphere (RA) for further analysis. Measurements included fruit weight, weight loss, firmness, total soluble solids (TSS), titrable acidity (TA), total sugars (TS), TS/TA, total phenolic content (TPC) and antioxidant activity (AA). CaCl2 had a positive impact on fruit firmness of all cultivars in both years. Higher values of TSS and TS of ‘Golden Delicious Reinders®’ were determined in CaCl2 treatment in both years. TSS, TS and TS/TA were increased by prolonging storage in ‘Red Chief’ in CaCl2 treatment and control, in both years. TSS and TS proved similarly stable in ‘Granny Smith’ during storage in CaCl2 treatment and control in the second year of examination, but a decrease of TA and TS/TA has been detected in both years of storage. The AA of cultivars ‘Golden Delicious Reinders®’ and ‘Red Chief’ was stronger affected by the storage compared to CaCl2 treatment. Through a comprehensive analysis of apple cultivars it can be concluded that pre-harvest application of CaCl2 in cultivars ‘Golden Delicious Reinders®’ and ‘Red Chief’ can be used to improve fruit quality during storage.

Sevtap Doksöz Boncukçu, Naif Geboloğlu, Funda Şahin

Hort. Sci. (Prague), 2023, 50(2):152-158 | DOI: 10.17221/62/2022-HORTSCI

This study was conducted to investigate the resistance of 4 wild eggplant species (Solanum aethiopium group Aculeatum, S. incanum, S. macrocarpon, S. linnaeanum), 3 cultivated eggplant varieties (‘Anamur F1’, ‘Pala’, ‘Yamula’), 1 eggplant rootstock (Köksal F1) and 34 interspecific hybrids to Verticillium dahliae Kleb. and Fusarium oxysporum f.sp. melongenae. Disease resistance of eggplant genotypes was determined by the pathogenicity test. The disease severity values varied between 0–80% for Verticillium and between 0–100% for Fusarium. Among the 42 genotypes, 18 genotypes were found to be moderately resistant and 1 genotype was found to be highly resistant to Verticillium. At the same time, 2 of the 42 genotypes were found to be moderately resistant and 22 of the 42 genotypes were found to be highly resistant to Fusarium. All hybrids with S. integrifollium, Solanum aethiopicum group Gilo as father were found to be highly resistant to Fusarium oxysporum f.sp. melongenae. Solanum linnaeanum did not exhibit any disease symptoms and was found to be highly resistant to both disease agents. Present interspecific hybrid eggplant genotypes with known resistance to Verticillium and Fusarium wilt are expected to have significant contributions in developing new eggplant rootstocks and hybrid eggplant cultivars in the future.

Vegetation dynamics, soil properties, and the correlation between them following a wildfire are crucial to understanding the recovery of forest (natural or planted forest) ecosystems. We compared species composition and soil properties in two burned (Br) and unburned (UBr) sites of loblolly pine (Pinus taeda L.) stand in Northern Iran. We detected 39 plant species including 22 (56.4%) species that were common in both sites, 13 (33.3%) species specifically in the Br site, and 4 (10.3%) species specifically in the UBr site. Although species abundance was significantly higher in the UBr site, species richness was significantly higher in the Br site. Species composition was significantly different (F = 16.25, P-value = 0.001) between Br and UBr sites. Rarefaction-extrapolation revealed consistently and significantly higher species diversity in Br site compared to UBr site for all three Hill numbers. Only sand (t = 2.23, P-value = 0.030), pH (t = 2.44, P-value = 0.018) and electrical coductivity (t = 2.98, P-value = 0.004) were significantly higher (P-value ≤ 0.05) in the Br site due to the demobilization of base cations in burnt vegetation. In the Br site, the wildfire did not cause any marked changes in C and N stocks.

Factors influencing the global agricultural trade: A network analysisOriginal Paper

Tingting Zhang, Ju Yang

Agric. Econ. - Czech, 2023, 69(9):343-357 | DOI: 10.17221/124/2023-AGRICECON


In this study, a global agricultural trade network was constructed, and its topological characteristics from 1991 to 2021 were analysed. The influences of nine variables were empirically tested, including factor endowments and economic, geographical, and institutional factors. The research results show that the scale of trade networks is constantly expanding, and trade relations are becoming increasingly concentrated. Further, global agricultural trade patterns are gradually being reshaped. However, European economies and the United States still dominate the power of network control, with a clear ‘core-edge’ hierarchy. Among the factors influencing the global agricultural trade network, differences in arable land areas, agricultural product prices, geographical distances, and financial institutions have proven important. However, their influence varies. Compared to the differences in the endowments of other factors, the comparative advantage of agricultural trade in various nodes worldwide comes more from the arable land areas. The greater the difference in agricultural prices, the closer are the trade ties between nodes. Differences in geographical distance have proven conducive to establishing agricultural trade relations. Finally, the greater the difference in financial systems, the greater the likelihood that agricultural trade links will occur.

Effect of low expression level of acetyl coenzyme A synthetase gene on secondary metabolite in MonascusOriginal Paper

Lin Lin, Chundan Zhang, Xinman Shao, Pupin Liu, Zhangfei Wu, Yanxia Lu, Hongzhen Guo

Czech J. Food Sci., 2022, 40(6):414-421 | DOI: 10.17221/4/2022-CJFS

Acetyl-coenzyme A (CoA) is a key metabolite produced by the acetyl-CoA synthetase (ACS) gene in energy metabolism and biosynthetic pathways. ACS is speculated to be the branching site of monacolin K (MK) and citrinin production and related to the metabolite production of Monascus. In this study, the ACS expression was inhibited by ribonucleic acid interference (RNAi). T7 was selected for a follow-up analysis of the lowest ACS expression, which was 0.401 times higher than that of the wild-type strain. The effects on the colony morphology of Monascus were determined. The morphological characteristics of mycelia and spores were observed under a scanning electron microscope. The contents of secondary metabolites, namely, MK and citrinin, were determined through high performance liquid chromatography (HPLC). Colour values were measured with a spectrophotometer. Results showed that the low ACS expression could inhibit the growth of Monascus colonies and the hypha and affect the formation and morphology of Monascus M1 spores. It could also inhibit the production of the main secondary metabolites, namely, MK, citrinin, and pigment.

Hui-Jie Li, Da-Long Guo, Jia-Bing Jiao, Yi-Man Fang, Yang-Yang Zhang

Hort. Sci. (Prague), 2023, 50(3):199-207 | DOI: 10.17221/73/2022-HORTSCI

Boric acid (BA) is commercially acceptable and economically feasible material to enhance the shelf life of pears, oranges and other horticultural plants. Here, we investigated the effect of BA on the shelf life and post-harvest quality of table grapes (cv. ‘Kyoho’). The grapes were immersed in a BA solution with different concentrations [0 (as the control), 10, 30, 50 mM] for 10 min and stored at 25 ± 1 °C for 10 days. Compared to the control, the BA treatments maintained higher berry firmness by inhibiting the activity of polygalacturonase (PG) and cellulase. In addition, the BA-treated grapes maintained higher antioxidant enzyme activities, such as catalase (CAT) and superoxide dismutase (SOD), and lower metabolic toxic products, like the superoxide anion (O2-) production rate, malondialdehyde (MDA) and hydrogen peroxide (H2O2) content than the control. The experimental results showed that the post-harvest application of BA effectively delays the senescence of grapes compared with the control, and the 10 mM BA treatment had the most obvious effect.

Impact of political and security stability on food security in developing countries: Case of Africa, Asia, Latin America and the CaribbeanCase Study

Jangkung Handoyo Mulyo, Imade Yoga Prasada, Agus Dwi Nugroho

Agric. Econ. - Czech, 2023, 69(9):375-384 | DOI: 10.17221/142/2023-AGRICECON


Political and security stability have the potential to support developing countries‘ efforts to achieve Sustainable Development Goals, as this region is home to the majority of the global population. This study examines the impact of political and security stability and other factors on food security [as measured by the prevalence of undernourishment (PUN)] in developing countries. We analysed 2002–2020 data from 83 developing countries across Africa, Asia, and Latin America and the Caribbean, using the system General Method of Moment (sys-GMM). Our study indicates that political and security stability and the use of the internet can increase food security or reduce PUN in developing countries. Other factors contributed to an increase in PUN: the previous year’s PUN, the cereal import dependency ratio and the unemployment to total population ratio. Meanwhile, other factors have varying effects on the PUN in developing countries.

Md Babul Akter, Azad Mosab-Bin, Mohammad Kamruzzaman, Reflinur Reflinur, Nazmun Nahar, Md Sohel Rana, Md Imdadul Hoque, Md Shahidul Islam

Czech J. Genet. Plant Breed., 2022, 58(2):64-72 | DOI: 10.17221/69/2021-CJGPB

Rice is one of the frontline cereals in the world and the major cultivated crop in Bangladesh. A total of eleven simple sequence repeats (SSRs) and thirteen sequence-tagged site (STS) markers were used to characterize twenty-four rice cultivars in Bangladesh. Twenty-four markers generated 60 alleles with 2.5 alleles per locus. The average polymorphism information content (PIC) value was 0.40, while the mean value of heterozygosity, gene diversity, and major allele frequency were recorded as 0.10, 0.48 and 0.62, respectively. However, the SSR markers showed more specificity and a higher discrimination power than the STS markers. The cluster analysis displayed four major clusters with a genetic similarity coefficient value of 0.73. The morphological analyses of the grain identified that Binadhan-20 and BRRI dhan34 had the longest and the shortest seed size, respectively, with a variable correlation between the seed length, width and length/width ratio. The phenol reaction test distinguished seven cultivars as japonica and seventeen cultivars as indica or an intermediate type. All these results regarding the phenotypic data and marker information will be useful for parental selection in modern rice breeding programmes.

Intensive initial care of silver fir using improving compounds: A way to support diverse forests?Original Paper

Channa Suraweera, Martin Baláš, Josef Gallo, Giuseppe D'Andrea, Stanislav Vacek, Jiří Remeš

J. For. Sci., 2023, 69(5):179-192 | DOI: 10.17221/178/2022-JFS


In some cases, it is difficult to promote climax tree species in the forest stand composition. In the Czech Republic, silver fir (Abies alba Mill.) is a typical example. This study offers an evaluation of the use of two improving compounds for tree plantations in the initial stage of growth in Central Bohemia. In the experiment, we measured the initial growth performance of a young fir plantation treated with a brassinolide compound (concentration 1 : 100 and 1 : 200) and Bio-Algeen® prior to planting and compared it with control treatment: we assessed height, root collar diameter, vitality and mortality rate during the period 2014–2019. Cumulative mortality rate of the plantation reached 25% at the end of the monitoring period, without any significant differences between variants. Height increment of the variant treated with Bio-Algeen® was significantly (P < 0.05) lower than the growth of brassinolide-treated variants, all treated variants were comparable with the control variant. The plantation underwent a drought-stress period in 2014 and 2015, which resulted in worsened vitality and colour across variants. As a result of the simple economic analysis, the most expensive inputs are planting stock and labour, therefore the price and application of additional substances should not affect decision-making.

The potential of Leersia hexandra grass in phytoremediation and natural attenuation of three groups of bacteria in soil contaminated with crude oil was evaluated for 180 days. The quantities of new shoots, root and aerial biomass were evaluated; changes in antioxidant concentrations in leaf and root caused by abiotic stress; population densities of Azotobacter, Azospirillum and Pseudomonas; and microbial respiration. The experimental data showed oil-induced increases of 315% and 196% in new shoots and root phytomass, respectively, and a 44% decrease in leaf + stem phytomass. The enzymatic defence in the grass leaf was manifested by higher concentrations of hydrogen peroxide, phenylalanine ammonium lyase and total flavonoids; the increases fluctuated from 35% to 52%. The response in the root was positive in catalase (16%), and in ammonium phenylalanine lyase, it increased 275% due to the effect of crude oil. The group of indigenous Azotobacter bacteria were tolerant to crude oil exposure, both in the phytoremediation process and in natural attenuation; the population densities varied from 212 to 438 × 103 colony-forming units (CFUs); they are greater than 49% to 106% compared to densities in control soil. Azospirillum spp. and Pseudomonas spp. recorded population abiotic stress. The grass activates enzymatic and plant defence, complementing microbial respiration in response to adaptation to crude oil.

Gabriela Tomášová, Tomáš Vichta, Nikola Žižlavská, Jan Deutscher, Ondřej Hemr, Martina Brychtová, Lenka Pavlů, Aleš Bajer

J. For. Sci., 2024, 70(4):185-201 | DOI: 10.17221/117/2023-JFS

This paper examines changes in soil physical and chemical properties in relation to tree proximity on different slopes. Topsoil and subsoil were sampled at 12 research plots on four slope types, the soil pits being placed at the base of a tree (near tree, NT) and between the test tree and an adjacent tree (between trees, BT). We observed a significant decrease in vertical topsoil response to slope on lower, middle and upper slopes, and a decrease in fine roots (R < 2mm) on flat ground. Overall, middle and lower slopes showed the highest similarity, and upper slopes and flat ground the least, with the greatest subsoil changes observed mainly on middle slopes and least on lower slopes. There was clear topographic dependence between subsoil water stable aggregates (WSA) and C dynamics, with BT total carbon (Ctot) higher on flat ground and lower on middle slopes; unlike topsoil, where the strongest WSA correlation was with distance from the tree. The highest N:OM (organic matter) ratios occurred on middle slopes facing north-west, and lowest on lower slopes facing north and flat ground. Our findings confirm the influence of slope type on soil characteristics, with NT soil supporting soil formation by transporting water to deeper layers, especially on slopes > 5°. These observations contribute to a better understanding of the dependence of soil properties on slope type and tree position when planning sustainable forest management.

Geographical forest zonation: Perspectives, history and useReview

Petr Dujka, Antonín Kusbach

J. For. Sci., 2024, 70(7):335-352 | DOI: 10.17221/5/2024-JFS

The rate of climate change advancement and its predicted impact are valid reasons for intense discourse on the topic of choosing the most suitable silvicultural and adaptation measures for the longevity and sustainability of forest communities. Changes in growth conditions of plants can be expected in both vertical (altitudinal) and horizontal (geographical) directions. The anticipated occurrence rate of these changes should, according to climate models, be higher than the natural adaptability rate of longevous tree species. This study focuses on the possibility of utilising regional geographical units of the Czech Republic (Central Europe) – Natural Forest Areas (NFAs) – for introducing the principles of assisted forest migration to national silviculture policies in order to find solutions for the predicted climate change scenarios. The primary objectives are (i) to review the history of the NFA concept, (ii) to discuss the perspectives of NFAs with regard to climate change, and (iii) to propose possible solutions for further development in comparison with alternative approaches to horizontal classification of the Czech Republic. This study is the first of its kind that provides a complete textual and graphic overview of the NFAs' history from 1959 to 2018, highlighting the purpose of NFAs as both frameworks for the maintenance of the genetic potential of forest tree species' populations and frameworks for long-term strategic management planning. Further development of the concept is discussed in connection with the main principles of assisted forest migration and the possibility of employing geospatial modellation analyses for a more precise definition of current NFA borders. An assessment of the areas' potential is also debated, mainly with an emphasis on the zonality of forest sites.

J. For. Sci., 2024, 70(10):512-528 | DOI: 10.17221/34/2024-JFS

Eucalyptus plantations are an important source of raw materials for the Thai forest products industry. Despite its economic value, only a few noncomprehensive papers have been published about the wood properties and fungal susceptibility of eucalyptus. Our study covered the most commonly used commercial eucalyptus clones with a wide variety of sizes from eastern Thailand. We assumed that the properties of the clones would differ based on the tree sizes. The objectives of this study were to determine the effects of diameter at breast height (DBH), size, and clone type on wood properties and mould susceptibility. The optimal usage of each log characteristic based on the log quality and properties could be used to determine the maximum payoff. The wood properties and log characteristics of five eucalyptus log classes with three clones were investigated. In general, the levels of means and standard deviations were as follows: the modulus of rupture (MOR) was between 39 ± 4.9 MPa and 66 ± 5.4 MPa, and the modulus of elasticity (MOE) was between 14.5 ± 9.7 GPa and 24.0 ± 2.7 GPa. In addition, the compression parallel to the grain was between 28 ± 3.2 MPa and 43 ± 2.4 MPa, and the compression perpendicular to the grain was between 13 ± 0.7 MPa and 19 ± 1.1 MPa. The shear strength parallel to the grain was between 10 ± 0.3 MPa and 14 ± 0.6 MPa. The cleavage and hardness were from 4.7 ± 1.6 N to 7.4 ± 0.9 N and from 3.6 ± 0.3 kN to 6.2 ± 0.6 kN, respectively. The toughness and nail withdrawal were from 27.3 ± 3.5 kN·mm–1 to 50.5 ± 1.0 kN·mm–1 and from 28.56 ± 4.1 N·mm–1 to 34.52 ± 2.8 N·mm–1, respectively. Eucalyptus clone K7 had lower MOR and other mechanical properties than clones K58 and K62 except MOE. When DBH increased, the mechanical and physical property values increased as well. This happened for all clones, and especially when DBH was over 200 mm. The results of this study showed that log characteristics, such as taper, slenderness, and crookedness, should be used for log grading standards and that each fast-growing eucalyptus clone could be applied to different product classes.

Dental health has historically received little attention in veterinary medicine, but is becoming more common. This study aimed to report the prevalence of dental extractions in dogs in Seoul, Republic of Korea, describe the current status of dental health and determine any preventive methods. In total, 166 dogs participated in the study, presented to the veterinary hospital with an oral disorder or for a routine check-up were included in the study. Teeth were extracted from 130 dogs (78.32%). A single tooth was extracted from 18 dogs (13.85%), whereas multiple teeth (2–29 teeth) were extracted from 112 dogs (86.15%). Ten teeth were extracted in 31 dogs (27.67%). In descending order, the most extracted teeth were PM2, PM3, PM4, and PM1. The age at the first dental check-up, the average interval between dental check-ups, and the average interval between the previous two dental check-ups in the extraction group were significantly greater than those in the non-extraction group. In contrast, the number of dental check-ups was significantly lower. In conclusion, this study suggests regular dental check-ups to prevent dental extractions. The data provide useful information for veterinary dental health management and the prevention of tooth extractions.

Effects of silicon on the transport, subcellular distribution, and chemical forms of lead in Salix viminalis L.Original Paper

Feifei Zhai, Menglong Yin, Jinmei Mao, Junxiang Liu, Haidong Li, Yunxing Zhang, Shaowei Zhang, Zhenyuan Sun

Plant Soil Environ., 2025, 71(4):249-258 | DOI: 10.17221/8/2025-PSE

Lead (Pb) is a harmful heavy metal that threatens ecosystems and plant growth. Silicon (Si) plays a crucial role in plant responses to heavy metal stress. In this study, the effects of Si on Pb2+ content and transport, subcellular distribution, and chemical forms in Salix viminalis L. under Pb stress were analysed, aiming to elucidate the detoxification mechanism of Si in S. viminalis under such conditions. Results showed that Si reduced Pb2+ in aboveground parts and increased it in roots, lowering its movement to leaves and stems. Analysis of the subcellular distribution of Pb2+ revealed that Si application promoted the transfer of Pb2+ to vacuole-dominated soluble components (F4) and cell wall components (F1), which increased the binding capacity of the cell wall and the vacuolar storage compartmentalisation for Pb2+. Changes in the chemical forms of Pb2+ indicated that Si significantly decreased the proportion of more mobile, ethanol-extractable Pb2+ (FE) and deionised water-extractable Pb2+ (FW) while increasing the proportion of less mobile Pb2+ forms, such as NaCl-extractable (FNaCl), HCl-extractable (FHCl), and acetic acid-extractable (FHAc) Pb2+, thereby reducing its mobility. This study provides empirical support for the application of Si in the phytoremediation of heavy metal-contaminated soils.

Plant Soil Environ., 2025, 71(6):387-397 | DOI: 10.17221/160/2025-PSE

The aim of this study was to investigate the physiological characteristics and quality of hypocotyls in the production of selenium-enriched sprouts from peanut seeds soaked in selenium (Se) solution. Peanut seeds were soaked with 0, 2.5, 5.0, 7.5, and 10 μmol/L Na2SeO3 for 12 h and then germinated. The results showed that the selenium concentration in peanut shoots increased with increasing levels of selenite soaking, and there existed a crossroads of selenite soaking concentration (5.0 μmol/L) when selenium concentrations in cotyledons and hypocotyls were equal. Below and above this concentration, Se concentrations in shoots were radicle > cotyledon > hypocotyl or cotyledon > radicle > hypocotyl, respectively. In addition, Se significantly promoted the elongation of hypocotyls and radicles, increased shoot biomass, increased the activity of antioxidant enzymes and the concentration of antioxidants in hypocotyls, and decreased malondialdehyde levels. Moreover, Se significantly increased the concentrations of soluble sugars, proteins, free amino acids and resveratrol in hypocotyls. These results indicate that soaking peanut seeds with selenite significantly increased Se concentration, biomass, antioxidant capacity and quality of peanut shoots. This study provides a theoretical basis for the rapid and standardised production of Se-enriched peanut shoots from selenite-soaked seeds.

The common vole (Microtus arvalis) is the main pest in agricultural areas of Central Europe. It is particularly important to monitor its numbers during spring, and if high numbers are detected, some form of pest management should be considered. In the Czech Republic, the number of active burrows is monitored using the burrow index, BI, which allows estimation of the total number of rodents, saves time and is easy to use. We aimed to assess the relationship between the burrow index and the relative abundance of the rodent species examined by snap trapping in crop fields. Bayesian MCMC algorithms with a zero-inflation model were used for this analysis. The positive relationship between BI and vole abundance occurred in the total sample of all fields and in alfalfa, winter wheat and barley crop fields. A positive relationship between BI and the abundance of the wood mouse (Apodemus sylvaticus), the second most common pest in the area, was only confirmed in barley, and this relationship was negative in winter rape. The positive influence of the degree of weed cover on BI was confirmed in the total sample and in winter rape and alfalfa, but weed cover has a negative effect on BI in barley and winter wheat. In contrast, weed cover did not affect the relative abundance of both rodent species in any of the sampled crops. The presence of shrubs and forests around the fields reduced BI in the whole sample, especially in alfalfa. The relative abundance of the voles was not affected by the presence of shrubs and forests around the crop. Still, a positive influence was confirmed for the abundances of mice in the whole sample and alfalfa. BI can be a reliable indicator of vole abundance in crops with high densities, but it is not very accurate at low densities and in crop fields rarely used by voles, such as sunflower and maize. 

Increasing Boro rice productivity through credit: Evidence from BangladeshOriginal Paper

Shah Johir Rayhan, Md. Sadique Rahman, Kaiyu Lyu

Agric. Econ. - Czech, 2024, 70(2):49-59 | DOI: 10.17221/341/2023-AGRICECON


Rice productivity needs to be increased to feed Bangladesh’s growing population. Productivity can be increased by adopting improved varieties and management practices, which require additional capital inputs. In this article, we aim to estimate the effect of formal and semiformal credit on rice productivity in Bangladesh. We surveyed 500 rice farmers to achieve these objectives. We used descriptive statistics, propensity score matching and Heckman’s endogenous treatment effect model to analyse the data. The findings indicate that literacy, television ownership and training positively influenced access to formal credit. In general, credit recipients achieved higher productivity than did non-recipients. In the situation of credit source-specific effect, we found mixed results. Given the estimated difference of 438 kg/ha to 495 kg/ha, the results indicated that formal credit recipients had significantly higher productivity than did formal credit non-recipients. In contrast, endogenous treatment effect model results suggested that both formal and semiformal sources of credit had a significant effect on rice productivity. Increased agricultural loan disbursement through formal and semiformal credit institutions is strongly advocated. Farmers’ decision-making abilities regarding the most effective source of credit can be improved through training in financial literacy. The central bank of Bangladesh, along with the credit regulatory authorities of non-governmental organisations, can implement appropriate agricultural credit programmes for farmers.

Application of biostimulation and bioventing system as bioremediation strategy for the treatment of crude oil contaminated soilsOriginal Paper

Ifeanyi Michael Smarte Anekwe, Yusuf Makarfi Isa*

Soil & Water Res., 2024, 19(2):100-110 | DOI: 10.17221/66/2023-SWR

The purpose of this study was to evaluate the application of biostimulation and bioventing for the treatment of crude oil-contaminated soils. The research needed to check how various industrial biostimulants will perform in the treatment of contaminated soils and whether or not there is a synergetic effect that has to do with the stimulant composition. Soil samples used for this study were collected from South Africa. The soil samples were air-dried for 24 h and subsequently passed through a standard sieve of 2 mm screen. The soil consists of 79.32% sand (2.00–0.02 mm), 14.71% silt (0.02–0.002 mm) and 5.97% clay (< 0.002 mm). A microcosm system containing 1 kg of soil contaminated with crude oil (5% w/w) for biostimulation (BSTc) treatment was amended with varying ratios of municipal wastewater (MWW) and brewery wastewater (BWW) to investigate the possible synergy. The bioventing (BVTc) treatment involves the supply of atmospheric air to the bioreactors through the vadose zone for 30mins flow duration every 48 h intervals at ambient condition for 28 days. The BSTc and BVTc treatments recorded 48–58% and 54–75% total petroleum hydrocarbon (TPH) removal efficiencies, respectively, as the BWW amendment noted appreciable removal compared to MWW, while the control treatment recorded 35%. The result showed that the attempt to boost the TPH removal efficiency using the bioventing with the wastewater amendment was effective, as the presence of enough oxygen in the system resuscitated the activities of the microbial community for enhanced TPH biodegradation. This study inferred that combined bioventing and biostimulation techniques proved to be an effective bioremediation strategy for the treatment of crude oil contaminated soils and could serve as a vital tool towards the mitigation of pollution aftermath faced by communities involved in oil production and/or processing activities.

Despite all the complications that arise with root research, such as slow, laborious, and unclear genetics, roots are a promising object of interest for breeders because many root traits are compatible with high yield potential. It is a great challenge for further research that there is a wide demand for information on the “hidden half of plant metabolism” from many research fields. We have summarized the main obstacles in root system research and sketched a solution for breeding in field conditions so that the result was more meaningful to the farmer. (i) The most important challenge in root research is linking the functional identification of root system properties with the aboveground parts. (ii) Field breeding is irreplaceable, and methods allowing the evaluation of roots under field conditions are indispensable. (iii) Low heritability of root system trait discourages breeders. However, root properties show broad genotypic variability, allowing the efficient use of these traits as selection criteria. (iv) The root traits are variable, and many fluctuate under the influence of environmental factors, which complicates efforts to define ideotypes and explains the different conclusions obtained by researchers from different environments. The breeding programs targeting the root system are sporadic even in a global context. This is a great reserve for breeding progress in the era of climate change, water scarcity, a possible shift to extensive farming systems, and in the era of environmental programs.

Pattern recognition receptors (PRRs) play multiple roles in plants. As a kind of PRRs, chitin elicitor receptor kinase 1 (CERK1) proteins were reported to function in plant resistance to fungal and bacterial pathogens, and tolerance to salt stress. In this study, a predicted cowpea CERK1 homologous gene, designated as VuCERK1, was identified by database search. VuCERK1 protein contains 618 amino acid residues, with a predicted molecular mass of 67.5 kDa and a predicted isoelectric point of 5.04. VuCERK1 shows 58% and 60% sequence identity with AtCERK1 and OsCERK1, respectively. VuCERK1 also shows similar subcellular pattern with AtCERK1 and OsCERK1, suggesting VuCERK1 may function in cowpea immune responses. Gene expression assay indicated, that VuCERK1 was expressed in four different seedling tissues tested, comprising first leave, epicotyl, hypocotyl and root, and it could be induced by salt stress. Furthermore, transient expression of VuCERK1 in Nicotiana benthamiana induced obvious cell death. In addition, heterologous overexpression of VuCERK1 in Arabidopsis thaliana conferred enhanced disease resistance to Pseudomonas syringae pv. tomato strain DC3000 hrcC- (Pto DC3000 hrcC-).

The study aims to identify the difference between the current and future strategic management of forest ecosystem services (FES) portfolios in public enterprises of Slovakia. The case studies focus on forest enterprises in Košice, Banská Štiavnica, Kremnica, and Bratislava, representing the best practice examples of providing cultural services in the country. A marketing decision-making model, Boston Consulting Group (BCG) matrix, was used to analyse each company's current FES portfolio. Content analysis assessed the data collected from interviews with managers of the public forest enterprises. Duncker's forest management approaches classification was applied to evaluate the future strategic management of the FES portfolio, and a horizon of 10 years was set. According to the results, the urban forest enterprise in Bratislava is an example of receiving a subsidy from the capital for building and reconstructing recreational facilities. Therefore, this FES portfolio is and will be the most balanced. The portfolio of the forest enterprises in Košice, Kremnica, and Banská Štiavnica will remain unchanged for the next decade, and they plan to use a combination management approach that caters to economic, ecological, and social needs and objectives. Urban forests in Bratislava will focus even more on close-to-nature forestry.

The teak bee-hole borer [Xyleutes ceramica (Walker, 1865)] is considered one of the most serious pests of teak (Tectona grandis) in Thailand. The present study investigates climatic and topographic variables affecting the infestation of teak trees by X. ceramica in 10 plantations and predicts the risk of infestation by the species under current and future climatic conditions in Thailand. At each plantation, 48 plots evenly distributed among twelve teak stands were sampled. The infested teak trees in the plots were assessed, and the coordinates of the tree positions were recorded. The maximum entropy (MaxEnt) model was used to assess the effects of environmental factors and predict the occurrence probability of the species using current and projected (2050) climate data based on the Shared Socioeconomic Pathways SSP1-2.6 and SSP5-8.5 scenarios from multiple global climate models. According to our results, high accuracy values [AUC (area under the curve) = 0.852, TSS (true skill statistics) = 0.775] of the model prediction were obtained, and the infestation was found to be driven much more by climate than by topographic characteristics. Above all, X. ceramica was found to prefer moderate temperatures in a highly distinct seasonal climate. Additionally, relatively low amounts of premonsoon rainfall are also found to be favoured by the species. The predicted risk map revealed that the northern region is the core area of X. ceramica infestation in Thailand under current and future climatic conditions, but the severity of infestation is predicted to gradually decrease under the predicted future climatic conditions. Recommendations for management to minimise tree damage caused by X. ceramica are also presented in this study.

Peptides play regulatory roles in various plant development and defence processes. They function as molecular messengers that detect threats and trigger defence responses. This study aimed to identify the genes encoding endogenous plant elicitor peptide precursors (PROPEPs) in bananas and their role in inducing resistance to Ralstonia syzygii subsp. celebesensis (Rsc). Two precursor genes, MaPROPEP1 and MbPROPEP1, were discovered and predicted to encode the precursor proteins of elicitor peptides, namely, MaPep1 and MbPep1. Both elicitor peptides contained 23 amino acids of the active elicitor peptide, which activated innate immune responses in banana resistance to Rsc. The disease assessment was conducted by inoculating banana plants with Rsc isolate MY4101 using the root-stabbing method. The results demonstrated that MaPep1 and MbPep1 pretreatment enhanced resistance to banana blood disease, as indicated by reduced disease severity and the absence of wilting for 7 days after infection. The expression of the MaPROPEP1, MbPROPEP1, MaLOX7, and Pr-10 genes was evaluated using qPCR and found to be upregulated by MaPep1 and MbPep1 injection followed by Rsc infection in aboveground banana tissues within 7 days. These findings prove that MaPep1 and MbPep1 are members of the Pep family and exhibit conserved functions across various plant species. This approach may be used to develop strategies for enhancing disease resistance in banana cultivation.

Crop production faces increased climate change and land degradation stresses, compromising global food security with the growing population. Maize (Zea mays L.) is a versatile crop used for food, feed, and raw materials, contributing significantly to global food systems. Abiotic stresses like drought and soil fertility limit its production. Fertilisation is an amelioration technique that optimises maize growth and yield by maintaining optimum nutrition and leveraging nutrient deficiency conditions. Precision agricultural tools like chlorophyll meters are essential for non-destructive chlorophyll assessment and nitrogen status. An experiment conducted at the University of Debrecen evaluated the impact of nitrogen (N) fertilisation (0, 90, and 150 kg/ha) and three maize cultivars (P9610-FAO 340, DKC4590-FAO360, and GKT376-FAO360) on physiological parameters, namely: relative chlorophyll content (SPAD), normalised differences vegetation index (NDVI) and grain quality. Results showed that SPAD and NDVI positively correlated (P < 0.05) with grain quality and yield. Nitrogen application significantly influenced SPAD. Maize cultivars and N rates with higher chlorophyll content had maximum yield. Cultivar responses to nitrogen rates significantly (P < 0.05) varied by crop year. Higher SPAD and NDVI values were associated with higher protein content. Therefore, SPAD and NDVI values could be used to analyse the nutrient requirements of maize under field conditions to estimate grain yield.

Oligopeptides constitute an important yet understudied component of soil’s dissolved organic nitrogen (DON) pool, representing a primary breakdown product of proteins. However, the mechanisms of oligopeptide uptake and utilisation by crop roots remain poorly understood in a plant nutrition context. We investigated the rate and spatial uptake pattern of 14C-labelled alanine and di- to pentapeptides of alanine in wheat and rice under sterile hydroponic conditions. Both species demonstrated the capacity to absorb N through amino acids and oligopeptides, with rice roots showing higher peptide uptake than wheat. Specifically, alanine absorption exceeded peptide uptake by 3–7-fold in rice and 6–9-fold in wheat. Using phosphor imaging, we demonstrated that alanine and oligopeptide uptake occurred throughout the root system, with the highest accumulation in the root tip and root hair regions. Further, spatial analysis revealed that peptide absorption rates in rice were 2–5 times higher in the 0–1 cm root section and 1.5–4 times higher in the 1–2 cm section compared to corresponding wheat root segments. We conclude that plants can directly take up amino acids and oligopeptides to acquire exogenous N, with marked differences occurring among species in both uptake efficiency and spatial uptake patterns.

This study was conducted to evaluate the effects of three nutrient solutions (Hoagland, Knop, and Hydro Umat F) on the growth, yield, and fruit quality of hydroponically cultivated yardlong bean (Vigna unguiculata subsp. sesquipedalis L.). Results showed that Hydro Umat F extended the plant lifespan (105.4 days) and flowering time (58.65 days), increased the number of branches per plant, and enhanced leaf SPAD values. Plants grown in Hydro Umat F also exhibited the highest yield, as indicated by the number of flowers per plant (46.12), number of pods per plant (20.81), pod length (54.15 cm), pod weight (20.06 g), and total pod weight per plant (417.45 g). The Hoagland solution also promoted plant growth and yield, with a growth duration of 96.74 days, an average of 17.63 pods per plant, a pod length of 47.34 cm, a pod weight of 17.14 g, and a total yield of 302.17 g per plant. In contrast, the Knop solution, containing only six essential nutrients, shortened the plant’s growth duration (76.37 days) and significantly reduced the growth and yield of the hydroponic yardlong bean. Regarding pod quality, the pods from plants grown in Hydro Umat F had higher vitamin C content (4.12 mg/g), total protein content (3.21 mg/100 g), and reducing sugar content (13.06 mg/g) compared to those grown in Hoagland and Knop solutions. The findings suggest that Hydro Umat F is a suitable nutrient solution for hydroponic cultivation of yardlong bean, contributing to increased plant yield and fruit quality. These results suggest that Hydro Umat F is a promising nutrient solution for enhancing yield and pod quality in hydroponic yardlong bean cultivation, particularly in the context of the decline in available agricultural land and the rise of urban agriculture in Vietnam.

Quantification of soil health dynamics relative to grazing can inform both agriculture and conservation. We conducted an experiment near Lingle, Wyoming, USA, on a semi-arid northern mixed-grass prairie from 2017–2019. Three grazing density treatments (NG – not grazed; MRG – moderate rotationally grazed a herd of 4 Angus heifers, and UHD – ultra-high density rotationally grazed a herd of 33 Angus cow-calf pairs) were replicated four times in a randomised complete block design across twelve – 0.405 ha paddocks. Soil sampling was conducted prior to grazing in June 2017, one-week post grazing in July 2019, and six weeks post grazing in August 2019 and included a suite of forage, ground cover, soil chemical, soil physical, and soil microbiological measurements. Grazing treatment did result in lower vegetation structure but had no effect on any soil variables (P > 0.05). Conversely, the sampling interval was more influential for predicting fluctuations in chemical (15 variables significantly different within at least one treatment) or microbiological (13 variables significantly different within at least one treatment) variables than grazing treatment. The study was conducted in an intact native prairie with initial and final values indicating "Very Good" soil health, including the saturated : unsaturated fatty acid ratio, an indicator of stress.

Comprehensive comparative study of Chiari-like malformation in veterinary and human medicineReview

This review aims to enrich our understanding of Chiari-like malformation (CLM) by combining human and veterinary insights, and providing a detailed cross-species overview. CLM is a developmental abnormality characterised by caudal displacement of the hindbrain into the foramen magnum due to an entire brain parenchymal shift caused by insufficient skull volume. This malformation leads to a progressive obstruction at the craniocervical junction, which disrupts the normal cerebrospinal fluid flow, leading to secondary syringomyelia. The clinical signs of CLM and syringomyelia include phantom scratching, head tilt, head tremor, ataxia, tetraparesis, pain, muscle atrophy, and scoliosis or torticollis. Magnetic resonance imaging remains the gold standard for diagnosing CLM, since it allows the visualisation of abnormal findings such as the caudal cerebellar herniation, caudal cerebellar compression from occipital dysplasia, and attenuated cerebrospinal fluid cisternae. Although various medical and surgical interventions, including foramen magnum decompression, can provide temporary symptomatic/clinical sign relief, current literature shows a lack of sustained long-term efficacy. Therefore, additional research is needed to evaluate the long-term effects of existing treatment strategies and to compare different techniques utilised in conjunction with foramen magnum decompression.

Anti-diabetic effect of rice extract constituents through the molecular inhibition of α-amylase and α-glucosidase activityOriginal Paper

Carbohydrate digestive enzymes like α-amylase and α-glucosidase can be used to treat and manage diabetes. By inhibiting these enzymes, carbohydrate digestion slowed down, lowering the level of glucose entry into the bloodstream and preventing postprandial hyperglycemia. However, the effectiveness of current antidiabetic agents is limited due to their adverse effects. Therefore, the current study explored natural inhibitors from the methanol extract of rice to combat this issue. Through an integrated approach, four different rice cultivars were analysed and found that red rice methanol extract compounds stigmasterol and 1,2-benzenedicarboxylic acid interacted with α-amylase and α-glucosidase. Additionally, further research on stigmasterol directs the structure-activity relationship studies that aid in managing diabetic conditions.
