Anti-diabetic effect of rice extract constituents through the molecular inhibition of α-amylase and α-glucosidase activityOriginal PaperSubhashini Ramakrishnan, Thomas Jebastin, Sumathy Raj, Ariyamuthu Ramathilaga, Rithik Selvaraj, Najat A. Bukhari A., Ashraf Atef Hatamleh, Anis AhamedPlant Soil Environ., 2024, 70(11):683-694 | DOI: 10.17221/150/2024-PSE 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. |
Serendipita indica improve seed germination and seedling growth of Lolium multiflorum Lam. through amelioration of osmotic adjustment, nutrient accumulation and Na+/K+ homoeostasis under salinity conditionsOriginal PaperBinghua Liu, Xinghong Liu, Lianjia Yu, Xingjian Dun, Hailin Ma, Fangchun Liu, Lin PengPlant Soil Environ., 2024, 70(10):644-655 | DOI: 10.17221/244/2024-PSE A pot experiment was carried out to determine the effect of Serendipita indica on the salt response of Lolium multiflorum Lam. Although the salinity decreased the root colonisation of S. indica by 28.34%, successful colonisation of S. indica increased the seed germination rate, fresh weight, leaf relative water content and chlorophyll content by 28.09, 59.01, 38.78 and 28.80%, respectively, compared with uncolonised seedlings. Under salinity, leaf malondialdehyde content, leaf relative electrical conductivity, as well as Na+ content and Na+/K+ ratio in leaves and roots of S. indica-colonised seedlings were decreased by 33.99, 33.31, 63.40% and 47.42, 85.66 and 55.88%, respectively, compared with uncolonised seedlings. Meanwhile, compared with uncolonised seedlings under salinity, the contents of proline in leaves, N, P and K+ in leaves and roots of the S. indica-colonised seedlings were increased by 47.47, 45.69 and 30.05%, and 41.77, 19.51, 19.18 and 155.00%, respectively. These results indicate that S. indica colonisation confers salt tolerance in L. multiflorum seedlings by enhancing osmotic adjustment via actively accumulating proline and K+, increasing the uptake of nutrients such as N and P, and improving Na+/K+ homoeostasis. The study would provide a new idea for the combined application of salt-tolerant plants and symbiotic microorganisms in the ecological restoration of saline-alkali lands. |
Effect of thermal management on vitellogenesis and maturation in indoor-reared pikeperch (Sander lucioperca)Original PaperUro¹ Ljubobratoviæ, László Ardó, Georgina Fazekas, Zoltán Horváth, Jovanka LukiæCzech J. Anim. Sci., 2024, 69(1):18-28 | DOI: 10.17221/136/2023-CJAS The present study aimed to assess the effects of thermal manipulation on the vitellogenesis and final oocyte maturation (FOM) in pikeperch. Two groups of fish were stocked in two separate tanks of the climate chamber. One group was stocked at 10-month age (THERMAL), while the other was continually kept under stable photothermal conditions until 19-month-age (CONTROL) and then transferred to a climate chamber. The progress of vitellogenesis was assessed via evaluation of the oocyte diameter at the mid- and late-autumn phases, and the gonadosomatic index (GSI) at the late-autumn phase. Finally, females from the CONTROL group were hormonally stimulated before (WARMING) and after (STABLE) increase of the temperature from wintering to spawning, and the FOM progress, ovulation and plasma levels of 17 α, 20β dihydroxy progesterone (DHP) were assessed. Significantly larger oocytes at the mid-autumn phase (878.8 ± 40.1 μm vs 836.5 ± 46.5 μm) as well as the GSI at the end of the autumn phase (10.5 ± 1.7% vs 7.6 ± 1.1%) were noticed in THERMAL fish. Significantly faster FOM was seen in fish under the WARMING post-stimulation regime, and these fish had higher DHP levels at the moment of hormonal stimulation (5.4 ± 1.4 ng/ml vs 3.8 ± 1.2 ng/ml). According to the obtained results, it appears that photothermal induction of fish at a younger stage might have a positive impact on the first spawning, while the WARMING thermal regime seems to be more efficient in stimulating the FOM in fish upon first wintering. |
Effect of physical energy on germination and seedling vigor of alfalfa seeds (Medicago sativa L.)Short CommunicationAli Hajizadeh Namin, Abbas Akbarnia, Rouzbeh Abbaszadeh, Ali Zenouzi, Majid MasoumianRes. Agr. Eng., 2024, 70(3):174-180 | DOI: 10.17221/114/2023-RAE Recently, non-thermal technologies have emerged as a means to ensure the safety of agricultural products while also promoting plant growth and reducing pathogenic and chemical contamination of seeds. An experiment was conducted to investigate the effect of various treatments on the germination characteristics of alfalfa seeds. The experiment utilised a completely randomised design with five treatments and three replications, including cold plasma exposure, direct current (DC) electromagnetic field, magnetic field, and a combination of plasma exposure with magnetic and electromagnetic fields. The treated seeds were compared to the control seeds (without exposure) in terms of seedling length, germination rate index (GRI), vigor index, and seed germination. The results indicated that cold plasma treatment and a combination of plasma and magnetic field treatment significantly increased the germination rate compared to the control and other treatments. Furthermore, the combined treatment of plasma and electromagnetic fields, as well as the individual treatment with magnetic fields, resulted in a significant increase in root length and, consequently, the allometric coefficient. Non-thermal technologies are a promising approach to enhancing seed performance, particularly in terms of the rate of germination and seedling length. |
The sex ratio of spruce bark beetles – Ips typographus (Coleoptera: Curculionidae: Scolytinae) captured in different types of trapsOriginal PaperMarie Zahradníková, Jaroslav Dostál, Petr ZahradníkJ. For. Sci., 2024, 70(12):603-609 | DOI: 10.17221/55/2024-JFS In forest protection, various types of trap systems are used against spruce bark beetles to treat the foci of infested areas. Traditionally, these include pheromone traps, treated trap trees, and recently also the application of Storanet insecticide nets used for the sanitation of infested wood (trees), which also serve as treated trap trees when pheromones are applied, and the Trinet P system, a variation to a treated trap tree – a tripod. On an aluminium tripod, there is a Storanet insecticide net baited with a pheromone dispenser similar to other types of trap systems. The sex ratio proves to be a significant aspect in the assessment of individual types of trap systems. It is more favourable to catch a larger number of female individuals given that they bear the future development of the population. With a higher number of captured male individuals, the number of females per one male in the insect gallery increases, and the population cannot be reduced sufficiently. The results show that all three types of measures can be characterised by a lower ratio of captured males (approximately 40%) and a higher representation of females (around 60%). Differences in individual types of trap systems are insignificant. |
A GLMER-based pedotransfer function expressing the relationship between total organic carbon and bulk density in forest soilsOriginal PaperVáclav Zouhar, Ale¹ Kuèera, Karel DrápelaJ. For. Sci., 2024, 70(12):619-633 | DOI: 10.17221/48/2024-JFS Owing to its role in mitigating CO2 in the atmosphere, the total organic carbon (TOC) stock of soil, a key component of the terrestrial carbon cycle, is of significant interest as regards climate change. To determine TOC stock, it is first necessary to determine the soil's bulk density (BD), determined through intact soil sampling; however, in forest soils, it can be difficult to determine BD in soils with high levels of stoniness and/or tree root coverage. Furthermore, the method is time-consuming and labour-intensive, making it impractical for studies over large areas. In such cases, BD can be determined using a pedotransfer function (PTF) expressing the relationship between forest soil TOC and BD. The aim of this study was to determine a forest soil PTF using actual data obtained from 777 soil pits dug as part of the Czech Republic's National Forest Inventory (NFI). Within the NFI, BD is assessed from undisturbed core samples, while TOC is assessed from mixed samples from the same soil genetic horizons. Both generalised linear (GLM) and generalised linear mixed-effects (GLMER) models were used, with the final GLMER model best expressing the relationship for individual natural forest areas within the NFI dataset. The GLMER-based PTF described in this study can be widely applied to accurately estimate soil BD via TOC concentration at temperate forest sites where stoniness and/or root cover previously made it technically impossible to take undisturbed samples using standard methods. |
Impacts of management and changed hydrology on soil microbial communities in a floodplain forestOriginal PaperJiøí Volánek, Martin Valtera, Ladislav Holík, Martin Kománek, Hana Burdová, Josef Trögl, Diana Polanská Nebeská, Jitka Novotná, Pavel Samec, David JuøièkaJ. For. Sci., 2024, 70(11):574-592 | DOI: 10.17221/44/2024-JFS Long-term human activities substantially altered floodplain regions of temperate Europe. Forest management and extensive changes in hydrology greatly affected natural floodplain soil properties, in which microbes play key roles. This study aims to assess the effects of human activities through a gradient of forest management intensity on soil microbial community (SMC), its biomass, activity, and structure. Soil chemical and physical-chemical properties were used to explain the general associations and within-site variation using principal component analysis (PCA), linear regression (LR) and linear mixed-effect regression (LMER) models. It was found that forest management application, regardless of its intensity, led to significant microbial biomass reduction. PCA revealed that microbial biomass, expressed as a sum of phospholipid fatty acids along with recalcitrant carbon fraction (ROC) best explained the variability in data. LR and LMER highlighted that bacteria are affected by floodplain forest management more than fungi, and that bacterial response to pH was highly diversified. Also, pH was identified as the best predictor of SMC structure and activity but not of its size. The study calls for further investigation in SMC interactions with ROC, soil-available Fe and Mn, and the role of redox-active metals in soil organic carbon degradation. |
Effects of elevated CO2 and cadmium stress on vegetable quality and cadmium accumulationOriginal PaperXiao Wang, Deyan Li, Xiaohui SongHort. Sci. (Prague), 2024, 51(4):270-277 | DOI: 10.17221/131/2023-HORTSCI The aim of this study was to determine the effects of elevated CO₂ (eCO2) on the quality and cadmium (Cd) accumulation of vegetables grown in soil with a background Cd level or in Cd-contaminated soil. We used four types of vegetable: pak choi (Brassica rapa L.), water spinach (Ipomoea aquatica Forssk.), cherry radish (Raphanus raphanistrum subsp. sativus (L.) Domin) and pepper (Capsicum annuum L.). Cd stress significantly reduced vegetable vitamin C and reducing sugar content; however, under eCO2, vitamin C and reducing sugar content levels were significantly higher than they were under ambient CO2 (aCO2) levels. The nitrate content of pak choi, cherry radish and pepper was reduced under eCO2, and the effect was more pronounced among plants grown under Cd stress. The Cd content of cherry radish and pepper roots grown under eCO2 and Cd stress was significantly reduced (29.2% and 18.5%, respectively) compared with plants grown under aCO2 conditions and Cd stress. The Cd transfer coefficient of pak choi and water spinach grown under eCO2 and Cd stress was significantly lower (22.7% and 25.2%, respectively) than under aCO2 conditions. Our data suggest that growing vegetables under eCO2 is beneficial, especially when grown in Cd-contaminated soil, because Cd accumulation is reduced and vegetable quality is improved. |
Identification and functional analysis of the HvWRKY1 gene associated with Qingke (Hordeum vulgare L. var. nudum Hook. f.) leaf stripe diseaseOriginal PaperGang Jing, Youhua Yao, Likun An, Yongmei Cui, Yixiong Bai, Xin Li, Xiaohua Yao, Kunlun WuCzech J. Genet. Plant Breed., 2023, 59(4):263-277 | DOI: 10.17221/14/2023-CJGPB To explore the role of WRKY transcription factors (TFs) in the resistance process of Qingke (Hordeum vulgare L. var. nudum Hook. f.), leaves of the leaf stripe disease-resistant variety Kunlun 14 and the susceptible variety Z1141 were sequenced by transcriptome sequencing (RNA-seq). A differentially expressed gene HvnWKRY1 was identified, and its disease-resistance function was preliminarily analysed. The result showed that the open reading frame (ORF) of the gene was 1 062 bp and encoded 354 amino acids. It contained the conserved WRKY domain (273–351) and belonged to the WRKY protein family. The phylogenetic tree results showed that HvWRKY1 was most closely related to Hordeum vulgare L. The WRKY family of Qingke, barley, maize and rice were divided into categories I, II, and III, among which HvWRKY1 was located in group III. Results of the quantitative real-time fluorescence PCR (qRT-PCR) showed that the expression of HvWRKY1 was significantly (P < 0.01) higher in leaf stripe infected leaves of Kunlun 14 than that of Z1141. In Arabidopsis thaliana transformed with HvWRKY1, resistance to Botrytis cinerea was enhanced. The RNA-seq analysis showed there were 824 differentially expressed genes (DEGs). Data of the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment indicated, that a plant-pathogen interaction pathway was enriched. This study is expected to provide a theoretical basis for further studies of functioning of the Qingke gene HvWRKY1 in resistance to the leaf stripe disease. |
Genomic SSR marker development in lentil (Lens culinaris Medik.) and assessment of cross-species/genera transferability to related legumesOriginal PaperMelike Bakır, ªehriban Demir, Cebrail Yıldırım, Abdullah KahramanCzech J. Genet. Plant Breed., 2024, 60(1):42-49 | DOI: 10.17221/57/2023-CJGPB Simple sequence repeat (SSR) markers are valuable genetic and genomic research tools and are extensively used in major crops. However, a paucity of available molecular markers in lentils (Lens culinaris Medik.) has significantly hindered genomic studies in this vital legume crop. In this study, we developed 33 new SSR markers for lentils using an enriched genomic library and tested their polymorphism in 10 lentil cultivars. We found that 16 (48.5%) SSR markers were polymorphic. The expected heterozygosity values of the polymorphic SSR markers ranged from 0.095 to 0.820, while observed heterozygosity values varied between 0.100 and 1.00. In addition, we tested the transferability of 86 SSR markers, including the 33 newly developed ones, to other legume species. Transferability rates of lentil SSR markers to other species varied between 13.76% (Vicia sativa L.) and 2.58% (Phaseolus vulgaris L. and Trifolium pratense L.). These new SSR markers could be used in further molecular breeding, population genetics, and genetic mapping studies in lentils and other legume species. |
Detecting land use/land cover changes and forest degradation: A case study of the lower Soummam valley, northern AlgeriaOriginal PaperMegdouda Smail, Zoubir Boubaker, Mohamed Sbabdji, Habib Mouaissa, Bimare KombateJ. For. Sci., 2024, 70(3):122-134 | DOI: 10.17221/86/2023-JFS The environment is characterised by subtle and major mutations that cause changes in land use/land cover. Analysis of its dynamics and identification of vulnerable areas are critical to maintaining ecosystem services. The aim of this research is to quantify and qualify land cover dynamics over a 30-year period. It will also highlight forest degradation from a supervised classification of Landsat satellite imagery (L5 TM1987, L7 ETM+ 2000, and L8 OLI/TIRS 2019). The dynamics of land use/land cover were investigated by a maximum likelihood approach using geographic information system (GIS) and remote sensing (RS). Six major land use and land cover (LULC) types were mapped (build-up, agriculture, forest, clearing, matorral and olive cultivation). The classification reports made it possible to assess a reduction in forest cover (from 14 470.11 ha to 5 203.26 ha) and an increase in buildings (from 6 033.69 ha to 9 515.61 ha), and agricultural land (from 9 517.59 ha to 12 338.19 ha). The results were validated by a kappa coefficient of 0.93, 0.91, and 0.96, which showed that the model had successfully predicted LULC changes. We anticipate that the results will provide a basis for decision-making as well as a starting point for further in-depth studies in sustainable management and development of natural resources in the study region. |
The effects of diverse microbial community structures, driven by arbuscular mycorrhizal fungi inoculation, on carbon release from a paddy fieldOriginal PaperXue Zhang, Xiaodong Yu, Yunxiao Cao, Jiani Yue, Shan Wang, Yunxia LiuPlant Soil Environ., 2024, 70(1):48-59 | DOI: 10.17221/340/2023-PSE Arbuscular mycorrhizal fungi (AMF) play a key role in regulating the carbon cycle in terrestrial ecosystems. However, there is little information on how AMF inoculation affects the carbon fluxes of paddy fields, which are major sources of global carbon emissions. We, therefore, designed an experiment to study the effects of AMF inoculation on methane and carbon dioxide emissions from a paddy field. Results showed that: (1) Among the tested factors, the C/N ratio was the main environmental determinant of microbial community structure in the investigated soil; (2) compared with traditional fertilisation (control), the soil C/N ratio increased by 2.1~15.2% and 1.4~10.5% as a result of AMF application alone (M) or in combination with mineral fertiliser (FM) throughout the growing season, respectively. This change shifted microbial community composition to higher G+/G− bacterial and fungal/bacterial ratios; (3) the microbial community change favoured soil carbon retention. Methane (CH4) emission peaks were reduced by 59.4% and 76.0% versus control in the M treatment and by 52.5% and 29.4% in the FM treatment in the midseason and end-of-season drainage periods, and CO2 emission peaks were reduced by 70.1% and 52.3% in the M plots and by 55.4% and 66.4% in the FM plots. |
Effects of selenomethionine on the growth and physiological characteristics of Scrophularia ningpoensis seedlingsOriginal PaperXiaoqing Zhang, Yi Luo, Changjuan ShanPlant Soil Environ., 2024, 70(3):176-187 | DOI: 10.17221/381/2023-PSE In order to provide a theoretical basis for the application of organic selenium (Se) in the production and cultivation of Scrophularia ningpoensis Hemsl. We investigated the effects of selenomethionine (SeMet) on the growth and physiological characteristics of S. ningpoensis seedlings. The results showed that SeMet significantly improved the antioxidant capacity by enhancing the activities of antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) in the leaves of S. ningpoensis, which significantly reduced the content of malondialdehyde (MDA) and hydrogen peroxide (H2O2), as compared to the control. SeMet also significantly improved the water metabolism by increasing the transpiration rate, stomatal conductance, water use efficiency (WUE), relative water content, and water saturation deficit of S. ningpoensis leaves. Moreover, SeMet significantly enhanced photosynthetic performance by decreasing non-photochemical quenching (NPQ) and increasing the soil and plant analyser development (SPAD) value, net photosynthetic rate, PSII actual photochemical efficiency Y(II), photochemical quenching (qP), PSII photochemical effective quantum yield (Fv'/Fm') and apparent electron transport rate (ETR). Meanwhile, SeMet significantly improved the plant’s height, basal diameter, root/shoot ratio and dry weight of shoots and roots in S. ningpoensis. Various SeMet 30 and 60 mg/L SeMet concentrations demonstrated better effects on the growth and physiological characteristics of S. ningpoensis. The above results indicate that appropriate concentrations of SeMet can enhance the growth of S. ningpoensis and can be improved by increasing its antioxidant capacity, water metabolism, and photosynthetic performance. This provides a theoretical foundation for using organic selenium in growing and producing S. ningpoensis. |
Medlar (Mespilus germanica), a novel natural host for Hop stunt viroid (HSVd)Original PaperHatice Diğdem OksalPlant Protect. Sci., 2024, 60(1):31-40 | DOI: 10.17221/93/2023-PPS Hop stunt viroid (HSVd) infects various plants such as citrus, hop, almond, grapevine, pear, plum, peach, mulberry, fig, and pistachio. Medlar trees in an orchard in Malatya province of Türkiye were surveyed for the presence of HSVd in 2021. Twenty leaf and flower samples were collected and tested by RT-PCR methods using pathogen-specific primers. HSVd was found in five of the twenty medlar samples showing novel sequence variations. Two of the five HSVd variations were chosen at random and registered in GenBank. Both Turkish HSVd isolates had genomes that were 300 nucleotides long. The complete genome sequence of these variations was compared to isolates in GenBank. The nucleotide sequences of HSVd isolates exhibited 89.7–100% similarity with HSVd isolates found in various crops worldwide. Analysing the alignment of multiple sequences and conducting phylogenetic analyses revealed that identified HSVd variants clustered with citrus Türkiye (MZ995256), citrus Italy (KC584022), citrus Iran (GQ260203) and citrus Japan (X06719) isolates with 100% similarity rate and citrus China (FJ716172) and citrus Spain (AF213503) isolates with 99.5% and 98.0% similarity rates, respectively. To our knowledge, this is the first report of medlar serving as a natural host for HSVd. HSVd infection in medlar could be a problem in the future, and additional study is needed. The infection appears to be latent, but it might be a source of infection for susceptible plants. |

Enhancing cattle production and management through convolutional neural networks. A reviewReviewJean de Dieu Marcel Ufitikirezi, Roman Bumbálek, Tomá¹ Zoubek, Petr Barto¹, Zbynìk Havelka, Jan Kresan, Radim Stehlík, Radim Kune¹, Pavel Ol¹an, Miroslav Strob, Sandra Nicole Umurungi, Pavel Èerný, Marek Otáhal, Lubo¹ SmutnýCzech J. Anim. Sci., 2024, 69(3):75-88 | DOI: 10.17221/124/2023-CJAS The rise in demand for animal products associated with global population growth has driven the world toward precision livestock farming, where convolutional neural networks (CNN) have gained increasing attention due to their potential to enhance animal health, productivity, and welfare. However, the effectiveness and generalizability of CNN applications in cattle production are limited by several challenges and limitations, which require further research and development to address. This systematic literature review aims to provide a comprehensive overview of the applications of CNN in cattle production. It identified some potential applications of CNN in this field and highlighted the challenges and limitations that need to be addressed to improve the effectiveness and efficiency of CNN applications in cattle production. It also provides valuable insights for researchers, practitioners, and policymakers interested in the use of CNN to enhance cattle production practices, animal welfare, and sustainability. Additionally, it also provides the reader with a summary of the literature on the fundamental concepts of convolutional neural networks and their commonly used model architectures in cattle production. This is because agriculture digitalisation is going more multidisciplinary and people from different areas of expertise may find it helpful to learn more from a combined source. |
Characteristic of soil moisture utilisation with different water-sensitive cultivars of summer maize in the North China PlainOriginal PaperHaoze Zhang, Mingliang Gao, Fuying Liu, Huabin Yuan, Zhendong Liu, Mingming Zhang, Quanqi Li, Rui ZongPlant Soil Environ., 2024, 70(4):210-219 | DOI: 10.17221/401/2023-PSE Summer maize cultivars are differently sensitive to soil moisture. To better understand the differences in water productivity of summer maize cultivars with different water sensitivity, a field experiment was conducted from 2020 to 2022. Three different water-sensitive summer maize cultivars were selected, including TY808 (high water-sensitive cultivar), DH605 (medium water-sensitive cultivar), and ZD958 (low water-sensitive cultivar). Soil water content (SWC), soil water storage (SWS), water consumption, water use efficiency, and grain yield were determined. The results showed that under rainfed conditions, the SWC of the medium water-sensitive cultivar DH605 in the deep soil layer was 2.1–18.2% lower than TY808 and ZD958, respectively, and the differences were significant in the 12th leaf stage (V12) and vegetative tassel stage (VT). The SWS of the high-water-sensitive cultivar TY808 was 0.7% to 6.4% higher than the other two water-sensitive cultivars from 2020 to 2022. The changes in SWS are related to the spatiotemporal distribution of precipitation. The water consumption of DH605 was higher than TY808 and ZD958 by 5.3% and 7.09% in 2020 and 2.9% and 2.8% in 2021; in 2022, DH605 is 2% higher than ZD958 and 2.8% lower than TY808, respectively. The yield of DH605 was 4.3–10.78% higher than the other two cultivars in the three-year experiment. Additionally, the 1 000-kernel weight of DH605 was the highest in TY808 and ZD958. DH605 has the highest water use efficiency, which was increased by 4.8–14.6% compared to TY808 and ZD958. Through path analysis, we found that the direct path coefficient of SWS in the VT stage on yield reached 0.999, indicating that soil moisture in the VT stage has the greatest impact on yield, followed by the blister stage (R2). In conclusion, our results suggest that the water consumption of summer maize during the VT stage is the highest, and the soil moisture condition in VT significantly affects the grain yield of summer. Planting DH605 in the North China Plain would harvest the maximum grain yield and water productivity. |
Use of the threshold segmentation method as an alternative for estimating the volume of forest industry residuesOriginal PaperCarlos Borrego-Núñez, Pablito Marcelo López-Serrano, Pedro Antonio Domínguez-Calleros, Jorge Luis Compeán-Aguirre, Artemio Carrillo-ParraJ. For. Sci., 2024, 70(3):135-143 | DOI: 10.17221/105/2023-JFS In recent decades, the interest in searching for procedures and strategies to make energetic and economic use of residues from different industries has been an important part of the political agenda. There are several methods to determine the volume of residues from the forestry industry, but they are too time-consuming to apply. The objective of the present study was to establish a simpler and more efficient method to quantify the volume of residues from the forest industry. Ten controlled piles were made with residues from a private sawmill in the city of Durango, Mexico. To calculate the volume, two manual methods and one automatic method were used to calculate the stacking coefficient of the piles, while the water immersion method was used to calculate the real volume. A completely random experimental design was used for the analysis, where an analysis of variance and mean comparisons were performed at a significance level of P ≤ 0.05. The results of the study show that the threshold segmentation method is faster, more practical and efficient than the other methods used. The estimation of the volume of these residues will contribute to generating sustainable alternatives for the development and use of forest industry resources. |

The use of enzyme assays to assess soil biodiversity of diverse land use systems integrating trees – Preliminary researchOriginal PaperMagdalena Myszura-Dymek, Barbara Futa, Gra¿yna ¯ukowska, Klaudia Ró¿owicz, Norbert B³oñskiSoil & Water Res., 2024, 19(2):122-131 | DOI: 10.17221/16/2024-SWR Most studies of agroforestry system biodiversity focus on assessing visible, aboveground biodiversity, largely ignoring soil biodiversity. To fill this gap, a preliminary assessment of soil biodiversity in an agroforestry system was undertaken based on changes in soil enzyme activity. The study was conducted in the village of Maziarnia, Lubelskie Voivodeship, Poland, Europe. Arable fields with spring wheat, mid-field trees and perennial mixed forest were selected for the study. Soil material for physicochemical analyses (pHH2O, pHKCl, sorption properties, total carbon and total nitrogen) and biochemical analyses (activity of acid phosphatase, alkaline phosphatase, urease and dehydrogenases) was collected in the spring and autumn of 2022. The present study showed that the biochemical properties of the soils of the selected study sites varied depending on the type of ecosystem determining habitat conditions. Each ecosystem that makes up the agroforestry system studied is characterised by a distinctive microbiome composition and its own level of enzymatic activity. The obtained results support the thesis that agroforestry systems significantly increase the functional diversity and overall biodiversity of agricultural landscapes. However, a full, objective characterisation of the processes taking place in agroforestry systems requires long-term monitoring. |
The impact of efficiency on the profitability of large farms in the Visegrad FourCase StudyZuzana Fuksová, David Mare¹, Milan KøápekAgric. Econ. - Czech, 2024, 70(9):457-464 | DOI: 10.17221/120/2024-AGRICECON The issue of productivity and performance in agriculture is significant because it affects a country’s competitiveness, sustainability, and self-sufficiency in agricultural production and is reflected in European policy. This study aims to determine which country had the most efficient large farms compared to other V4 countries and whether efficiency in each country translates into the performance of large farms. The data were obtained from the EU FADN (Farm Accountancy Data Network) database from 2005 to 2019. These data were then evaluated using the statistical methods DEA: CCR-O (Data Envelopment Analysis: constant returns to scale), DEA: BCC-O (Data Envelopment Analysis: variable returns to scale), and Pearson correlation coefficient. Regarding international comparisons in achieving efficiency as measured by DEA, Hungary is the best performer among the countries compared, followed by Czechia, Poland, and Slovakia. The correlation between efficiency and performance measured by Farm Net Value Added was demonstrated only for Hungary. The international comparison provided information about which country had the most efficient large farms, what the ranking of countries was in terms of efficiency, and for which countries efficiency had / did not have a potential impact on performance. At the same time, the relationships regarding the efficiency and performance of farms with an economic size above EUR 500 000 of standard output were clarified. |
First report of Colletotrichum nigrum causing tomato anthracnose in SerbiaShort CommunicationRenata Ilièiæ, Jovana Blagojeviæ, Ferenc Bagi, Ðina Konstantin, Vojislav Trkulja, Nenad Trkulja, Tatjana Popoviæ MilovanoviæPlant Protect. Sci., 2024, 60(3):305-309 | DOI: 10.17221/14/2024-PPS During the survey of open tomato fields in Vojvodina (Serbia), characteristic anthracnose disease symptoms, including black, circular, sunken, and watery lesions, were observed in about 20% of fruits in September 2018. Subsequent pathogen isolations formed white aerial mycelia and numerous spherical, black conidiomata on the Potato Dextrose Agar. Ten representative isolates produced hyaline, smooth-walled, cylindrical, and aseptate conidia. The presence of initially brownish necrotic lesions on the tomato, which later expanded into large rotted areas, ultimately leading to complete fruit rot, confirmed the pathogenicity of the tested isolates. Molecular identification was performed using Bayesian analysis of concatenated ITS, TUB2, CHS-1, and ACT loci. Based on the combination of the morphological and molecular features, the fungus Colletotrichum nigrum was identified as the causal pathogen. As this is the first report on this fungal pathogen on tomatoes in Serbia, it highlights the importance of early and accurate detection for effective disease prevention, thus reducing crop damage and market losses. |
Comprehensive comparative study of Chiari-like malformation in veterinary and human medicineReviewJH Jung, H Park, WS Kim, HY YoonVet Med - Czech, 2024, 69(7):217-233 | DOI: 10.17221/125/2023-VETMED 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. |

Transcriptome analyses reveal the toxicity of graphene oxide with different diameters on buckwheat root growthOriginal PaperChangying Liu, Hanlin Wang, Han Li, Qingcheng Qiu, Dabing Xiang, Yanxia LiuCzech J. Genet. Plant Breed., 2024, 60(4):237-248 | DOI: 10.17221/69/2024-CJGPB Graphene-based materials (GBMs) have become potential soil pollutants due to their wide applications in agricultural environments. Although physiological mechanisms of plant responses to GBMs have been previously explored, the underlying molecular mechanisms remain unclear. In this paper, we analysed the physiological and transcriptomic changes of buckwheat (Fagopyrum spp.) roots exposed to 100 mg/L graphene oxide (GO) with different diameter. GO negatively affected root growth and higher diameters of GO caused more adverse effects on the root. In total 3 724 GO-responsive genes were identified in root by transcriptome analysis. 70 differentially expressed genes (DEGs) were involved in ROS detoxification, and 37 transporter-encoding genes were found to be involved in GO response. These transporters may regulate the uptake and transport of GO in buckwheat. The gene expression of 84 transcription factors (TFs) showed a response to GO stress in the root, which may regulate the transporters and reactive oxygen species (ROS) detoxification-related genes. Finally, the difference in the transcriptomic response of the root to the three GO materials with different diameters was investigated. 49 GO-responsive genes may be involved in the difference in the toxicity of GO with different diameters. This study provides new insights into the molecular mechanisms of plant roots to GBMs. |
The effect of parameter adjustment in sago palm classification-based convolutional neural network (CNN) modelOriginal PaperSri Murniani Angelina Letsoin, David HerákRes. Agr. Eng., 2024, 70(3):123-133 | DOI: 10.17221/65/2023-RAE In our study location, Merauke Regency, the easternmost city in Indonesia, the sago palm is associated with different types of ecosystems and other non-sago vegetation. During the harvesting season, the white flowers blossoming between the leaves on the tops of palm trees may be distinguished manually. Four classes were determined to address the visual inspections involving different parameters that were examined through the metric evaluation and then analysed statistically. The computed Kruskal-Wallis test found that the parameters vary in each network with a P-value of 0.00341, with at least one class being higher than the others, i.e., non-sago with a P-value of 0.044 with respect to precision, recall, and F1-score. Thus, the general linear model (GLM) was tested specifically in trained Network-15 and Network-17, which have similar parameters except for the batch size. It indicated the two networks' differences based on their prediction results, classes, and actual images. Accordingly, a combination of learning rate (Lr) and batch size improved the reliability of the training and classification task. |
