Water content in soil afforested with a mixture of broadleaves or Scots pineOriginal PaperJan Vopravil, Pavel Formánek, Tomá¹ Khel, Karel JackoJ. For. Sci., 2024, 70(2):91-101 | DOI: 10.17221/114/2023-JFS Afforestation of agriculturally used land has many benefits which are described in different publications. As stated in these publications, afforestation of agricultural land can influence soil water content because of rainfall interception and concentration, transpiration, and properties of forest floor layer and soil; also, hydraulic lift may occur. In this study, we attempted to find changes in volumetric soil water content values (at depths of 20 cm, 40 cm, and 60 cm) on agriculturally used land afforested with a mixture of forest tree species (Quercus robur L., Quercus rubra L., and Acer platanoides L.) or Pinus sylvestris L. in the year 2011 (and on agriculturally used land = control). This study was performed in the period from the end of March 2021 to the beginning of April 2022. In this study, we proved our hypothesis on the reduction of volumetric soil water content after afforestation; it is probably because of higher rainfall interception and evapotranspiration as described in different studies. Concerning the afforestation, the average volumetric water content was higher on the plot afforested with broadleaves compared with Scots pine. It was especially in the period after defoliation when the proportion of throughfall (and stemflow) increased on the plot with broadleaves. Our results indicate a higher water-storage capacity of forests compared with agriculturally used land. During the leafless period, this capacity was found to be higher after afforestation with Scots pine. |
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. |
The effects of biochar grain size on radish plants under low water availabilityOriginal PaperLenka Botyanszká, Justína Vitková, Natália Botková, Lucia Toková, Ján Gadu¹Plant Soil Environ., 2024, 70(4):203-209 | DOI: 10.17221/414/2023-PSE Low water availability is a significant constraint on global crop production. Exploration is needed regarding plant responses to drought in interaction with biochar, encompassing optimised water use and carbon allocation strategies. The size of the biochar particles also plays an important role, especially in influencing the dynamics of water and plant growth. This study explored the potential impact of biochar treatment on radish growth and drought tolerance. Finer biochar particles lead to the most substantial available water content for plants, increasing at around 30%, while medium and larger fractions increase by about 22% and 16%, respectively, compared to control soil. The chlorophyll fluorescence technique showed improved water management of drought stress at larger fractions of biochar. Our research underscores the potential of biochar treatments for environmental stresses and water scarcity in modern agriculture. |
Evaluation of the total phenolic content, sugar, organic acid, volatile compounds and antioxidant capacities of fig (Ficus carica L.) genotypes selected from the Mediterranean region of TürkiyeOriginal PaperMuhammet Ali Gündeºli, Remzi Ugur, Ipek Urün, Sezai Ercisli, Nesibe Ebru Kafkas, Gulce Ilhan, Velibor Spalevic, Riaz Ullah, Ahmed BariHort. Sci. (Prague), 2024, 51(2):111-126 | DOI: 10.17221/84/2023-HORTSCI Nowadays, the interest in research to determine the healthy compounds in fig fruits has increased, as many of them have been found to be beneficial to human health. This study aimed to determine the sugars, organic acids, total phenolic content, antioxidant capacity and volatile compounds in the fruits of 19 fig (Ficus carica L.) genotypes sampled from the Kahramanmaras province in Türkiye in 2018 and 2019. In the fruit of the fig genotypes, the total phenolic content was determined by the Folin-Ciocalteu method, the total antioxidant capacity was determined by the DPPH (2,2-diphenyl-1-picrylhidrazil) method, the sugars, organic acids and volatile aroma compounds were determined chromatographically (HPLC/RID detector), (HPLC/UV detector) and headspace gas chromatography-mass spectrophotometry (HS-GC/MS), respectively. The results showed that most of the biochemical contents and antioxidant capacities of the genotypes significantly differed from each other (P < 0.05). The total phenolic content and antioxidant properties of the fruits ranged from 50.29 to 580.59 mg gallic acid equivalent per 100 g fresh weight base (and 15.98 to 36.77% DPPH, respectively. Regarding the sugar content of the fig genotypes, the main sugar is fructose ranging from 3.35 to 7.37 g per 100 g. The highest fructose content of 7.37 g per 100 g was found in the genotype KMF12. A total of 58 volatile compounds were detected in the fruits of the 19 fig genotypes, including 18 aldehydes, 3 ketones, 6 esters, 2 terpenes, 17 alcohols, 1 acid and 11 other compounds. According to the obtained results, aldehydes, esters and ketones were found to be the major volatile compounds in the fig fruits. The genotypes with the highest values of the phytochemical and antioxidant properties among the genotypes were selected as candidates as a source of variation for breeders who want to develop new commercial varieties beneficial to human health. |
Overgrazing strongly impedes the natural regeneration of the endemic Boswellia species on Socotra IslandOriginal PaperSalem Hamdiah, Klemen Eler, Kay Van Damme, Fabio Attorre, Dario La Montagna, Michele De Sanctis, Mohammed Shaneyehen, Mohammed Amar, Theodore Danso Marfo, Petr MadìraJ. For. Sci., 2024, 70(5):249-263 | DOI: 10.17221/3/2024-JFS Frankincense trees (Boswellia spp.) worldwide are affected by a number of threats, including global warming and changing land management practices. On the Socotra Archipelago (Yemen), which harbours eleven endemic Boswellia species, grazing is generally assumed to be one of the main threats preventing natural regeneration. To test the impact of overgrazing on natural regeneration, we established an in situ experiment on four different Boswellia taxa in different areas of Socotra Island. Mortality and the height increment of seedlings were measured for a period of two/three years in five plots excluded from grazing (fenced) and in five paired control (unfenced) plots. Each plot was 50 m × 50 m in size and contained several adult trees as a source of viable seeds. Our results show that seedling mortality was significantly higher, and seedling height increment generally (4 out of 5 sites) lower in open compared to fenced plots. In the fenced plots, the number of seedlings for all species reached up to 772, with 560 surviving seedlings. In comparison, the control plots reached up to 296 seedlings, with 176 seedlings surviving after 2–3 years. The results of our experimental study indicate that grazing directly threatens the natural regeneration of the endemic Boswellia on Socotra Island. However, seedling mortality remained relatively high inside the exclosures as well, which indicates that even without the pressure of livestock grazing, other impacts remain a challenge for the future conservation of the archipelago's unique frankincense trees. |
Comparison of the blossom and shoot susceptibility of European and Asian pear cultivars to Pseudomonas syringae pv. syringaeOriginal PaperIveta Pánková, Václav Krejzar, Radka KrejzarováHort. Sci. (Prague), 2024, 51(2):85-97 | DOI: 10.17221/18/2023-HORTSCI The susceptibility of 14 pear cultivars to the bacterium Pseudomonas syringae pv. syringae, the causal agent of bacterial blast, was evaluated using three different methods of in vivo inoculation detached shoots inoculation in a growth chamber, and terminal shoot and blossom inoculation of potted trees in a net house in the period 2020–2022. The 20-week assessment of infection symptoms in the net house showed different dynamics of disease development depending on the inoculation method, the weather during the growing season and the susceptibility of the pear cultivars. Most of the cultivars were during the study low susceptible to pathogen and were classified in blossom, terminal as well as detached shoot susceptibility class 2. The European cultivar Kiefer was the least susceptible (susceptibility class 1) to blossom infection, the Asian cultivars Chojuro and Ya Li to terminal shoot infection, and Ya Li to detached shoot infection. The European cultivar William’s was the most susceptible to all types of infection, being classified in class 3, moderately susceptible cultivars to infection of terminal shoots, and class 4, highly susceptible cultivars to infection of blossoms and detached shoots. The assessment of susceptibility of pear cultivars to Pseudomonas syringae pv. syringae in the net house approximated conditions as close as possible to the condition in orchards and should thus be consistent in plantings with similar environmental and weather conditions. |
Essential oils of indigenous citrus varieties of Northeast India as potential antibiofilm agents against foodborne pathogens: An in vitro and in silico studyOriginal PaperSurjya Loying, Rajeev Sarmah, Manash Pratim Sarma, Abdul Malik, Suhail Akhtar, Azmat Ali Khan, Rahul Nayak, Devabrata SaikiaCzech J. Food Sci., 2024, 42(3):153-162 | DOI: 10.17221/179/2023-CJFS The unique structural and biological diversity found in plants renders them a distinctive and sustainable source for discovering new antibacterial, antifungal and antiparasitic compounds. In the present study, antimicrobial and antibiofilm properties of essential oils of citrus varieties of Northeast India were studied against selected foodborne pathogens using both in vitro and in silico approaches. These essential oils showed significant antimicrobial and antibiofilm activities against foodborne pathogens. i.e. Bacillus cereus MTCC430 and Yersinia enterocolitica MTCC859. It was observed that the treatment with essential oil disturbed the membrane integrity of the pathogens, thereby causing the release of nucleic acids. This study also postulated that active compounds of the essential oils interact with different target proteins of the pathogens and provide an explanation for the mechanisms of antimicrobial and antibiofilm action of the essential oils of citrus varieties against foodborne pathogens. |
Can income growth and environmental improvements go hand in hand? An empirical study of Chinese agricultureOriginal PaperChenchen Su, Jinchuan Shen, Fei WangAgric. Econ. - Czech, 2024, 70(7):321-333 | DOI: 10.17221/438/2023-AGRICECON Advancing agricultural carbon emission efficiency and farmers’ income simultaneously is crucial for the sustainable progress of agriculture. Our study centered on 31 provinces and cities in China and investigated regional variances and the dynamic evolution aspects of coordinated development in farmers’ income and agricultural carbon emission efficiency, utilising panel data from 2005 to 2021. The analysis revealed the following trends: Firstly, China’s overall agricultural carbon emission efficiency was steadily increasing, mainly because of technological advancements. Secondly, the correlation between farmers’ income and agricultural carbon emission efficiency in China had notably improved from 0.318 to 0.775. Throughout the observation period, disparities in the levels of coordinated development were observed in various provinces with a diminishing fluctuation, indicating regional disparities as the primary instigator. Thirdly, the level of coordinated development highlighted positive clustering attributes, demonstrating an ‘east high, west low’ pattern; the evolution of coordinated development levels exhibited stability in maintaining the current status. This study holds significant value for developing countries in enhancing farmers’ income and agricultural carbon emission efficiency in a coordinated manner. |

Unravelling risk factors in Turkish wheat in a changing global landscapeOriginal PaperHuseyin Tayyar Guldal, Ozdal Koksal, Osman Orkan Ozer, Onur Terzi, Erdogan Gunes, Aysegul SelisikAgric. Econ. - Czech, 2024, 70(11):527-540 | DOI: 10.17221/173/2024-AGRICECON This study comprehensively examines multifaceted risk factors influencing wheat production among Turkish farmers, aiming to deepen understanding of how these factors shape farmers’ perceptions and decision-making processes. Utilising Structural Equation Modeling (SEM), we analysed the interplay of climate-related issues (F1), market dynamics (F2), and external events (F3), like COVID-19 and wars, alongside socio-demographic factors such as education, income, and land ownership. Findings revealed that higher education and increased agricultural income reduced price-related risks while expanding wheat cultivation areas heightened risk perceptions. Farmers in irrigated regions prioritised cyclical risks, whereas those in dry areas perceived climatic risks as more severe. Capital-intensive practices and storage facilities mitigate climate change and market variability risks, with committed wheat producers showing lower climate change risk perceptions. External factors like the Russian-Ukrainian war and the COVID-19 pandemic disproportionately impact irrigated area farmers. This study contributes to the existing literature by using empirical evidence from Turkish wheat farming to explore diverse risk perceptions, employing SEM to unravel complex risk factors and decision-making processes, thereby offering new insights for future agricultural risk management research. |
Molecular identification of yellow rust resistance genes in some wheat and triticale cultivars and their resistance to Puccinia striiformis f.sp. triticiOriginal PaperEmad Mahmood Al-Maaroof*, Sarkawt Hama Salih AliCzech J. Genet. Plant Breed., 2024, 60(4):223-236 | DOI: 10.17221/39/2024-CJGPB Yellow rust (YR), caused by Puccinia striiformis f.sp. tritici (Pst), is a global threat to wheat production. In this study the response of 46 wheat and triticale cultivars to Pst at the adult plant stage (APS) was evaluated during two successive growing seasons at Sulaimania, Iraq. Also, we used a molecular analysis to find the yellow rust resistance (Yr) genes present in the individual cultivars. The results revealed large differences in the response to Pst between the cultivars. Most of the cultivars were susceptible to YR; the mean coefficients of infection (CI) varied from 0.23 in cv. Sarah to 83.33 in Hsad. High resistance levels were found in Al-Wand, Kalar 1, Rezan, and Sarahat APS, while Al-Rashid, Charmo, Faris 1, Maaroof, Rabiea, and Iratom displayed moderate resistance. The level of Yellow rust infection was higher in 2023 than in 2022 in most tested cultivars. Molecular analysis revealed the highest number of Yr genes (Yr2, Yr5, Yr7, Yr9, Yrvav, Yr15, Yr24, Yr26, and Yr32) in the cv. Al-Wand, followed by Sulaimani 2 with eight Yr genes (Yr2, Yr5, Yr7, Yr9, Yr15, Yr24, Yr26, and Yr32). Only one Yr gene was found in Iratom and Tamuz 3. Yr2 was the most frequently identified gene, present in the majority of tested cultivars (87%), followed by Yr7 (76%) and Yr9 (74%), respectively. |
Critique on the dipteran pests of commercial flower crops: An obligate threat to the floral industryReviewBabu Babu Sreelatha Anand, Kanna Selvaraj Suganya, Chinnaiah Muthiah, Jacob Rajangam, Subramanian Rajesh, Ramayya Nalini, Angappan SuganthiPlant Protect. Sci., 2024, 60(4):328-353 | DOI: 10.17221/29/2024-PPS The floral industry grapples with challenges like changing climatic scenarios, differences in market trends, rising costs, and severe losses posed by insect pests. The management of dipteran pests encompassing diverse species, such as leaf miners, midges, flies, and mosquitoes, has emerged as an obligate adversary, inflicting substantial economic losses in the cut and loose flower industry. Through a comprehensive analysis of existing literature, this paper delves into the diverse array of dipteran species of leaf miners and midges, their life cycles, distribution, host range, damaging symptoms, insecticide resistance, and the management strategies practised to date. Furthermore, this critique underscores the urgent need for innovative approaches and integrated pest management techniques to mitigate the escalating menace of dipteran pests. By elucidating the multifaceted challenges and proposing strategic interventions, this critique aims to foster dialogue and inspire concerted action among researchers, stakeholders, and scholars to safeguard the sustainability and profitability of the floral industry. |
Will cultural and regulatory forest services provide enough balance to provisioning services in forest enterprise portfolios in future? Marketing case studies of selected forest enterprises in SlovakiaOriginal PaperAlex Bumbera, Daniel Halaj, Iveta HajdúchováJ. For. Sci., 2025, 71(2):59-71 | DOI: 10.17221/68/2024-JFS 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 Ko¹ice, Banská ©tiavnica, 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 Ko¹ice, Kremnica, and Banská ©tiavnica 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. |
Combined lactase and trehalase deficiency as a cause of blood lose in young manShort CommunicationNatalie Friedova, Diana Chrpova, Jana Tajtlova, Martina Kollerova, Pavel KohoutCzech J. Food Sci., 2025, 43(1):71-74 | DOI: 10.17221/14/2024-CJFS Trehalose is a disaccharide composed of two glucose that can be found in various plant and animal species. Mammals are not able to synthesize trehalose but it is usually easily enzymatically broken down into 2 molecules of glucose. As a structural additive, trehalose can be used in food mainly for stabilizing proteins. Low trehalase activity (primary trehalase deficiency) leading to intolerance is rare but may appear manifest as a complication of enteropathy from other causes (celiac disease, Crohn's disease, etc.). We present the case of a young 27-year-old male with repeated tenesmus followed by enterorrhagia, weight loss, and elevated markers of inflammation caused by combined lactase and trehalase deficiency. Unique exome sequencing analysis of gene TREH was performed to distinguish between primary and secondary trehalase deficiency. |
Association analysis of the molecular characteristics and floral traits of Iris × germanicaOriginal PaperFeng Tian, Ya Tian, Fang Yu, Jinsen Qian, Feijian Wang, Xue Li, Tongyin Li, Xiaofei Zhang, Dazhuang Huang, Xiaojie ZhaoCzech J. Genet. Plant Breed., 2025, 61(2):55-66 | DOI: 10.17221/93/2024-CJGPB Iris × germanica L. (bearded iris) is a popular ornamental plant with numerous commercially important cultivars; however, little is known about the genetic diversity and population structure of the species, as limited DNA markers have been explored. In this study, 34 722 expressed sequence tag (EST)-simple sequence repeat (SSR) loci were identified from RNA sequencing data. The most abundant SSR motifs belonged to the tri-nucleotide type, of which the most common were AGG/CCT followed by AAG/CTT. Overall, 50 primer pairs derived from these EST-SSRs were randomly selected and synthesized, and 22 primer pairs with good polymorphism effects were used for the following experiment. Correlation analysis of nine floral traits showed that most floral traits had significant correlations with each other. Association analysis between SSR molecular markers and nine floral traits showed that 11 EST-SSR markers were associated with 3–6 floral traits. The cluster tree constructed by using the unweighted pair group method demonstrated that the cultivars that had the same parents or similar colour were clustered together. The genotypic relations of most cultivars were consistent with their pedigree-based relationships. The EST-SSR loci identified in this study will facilitate the exploitation of genetic resources and molecular breeding of I. × germanica. |
Effect of genotype and leader type on benzyladenine induced sylleptic branching in apple nursery treesOriginal PaperKishan Lal Kumawat, Wasim Hassan Raja, Javid Iqbal Mir, Susheel Kumar RainaHort. Sci. (Prague), 2025, 52(1):33-41 | DOI: 10.17221/139/2023-HORTSCI The planting of branched nursery trees is an essential component of most high-density orchard planting systems to induce precocity. However, in apples, most cultivars do not produce the desired numbers of sylleptic shoots naturally due to the presence of apical dominance. Benzyladenine (BA) applications alter the apical dominance and consequently encourage sylleptic shoot formation in nursery trees. However, the response to an exogenous BA application can vary with the genotype. Currently, most nurseries produce branched apple nursery trees using the renewal leader method. However, apart from the renewal leader method, branched nursery trees can also be produced using the central leader method. A comparative study of these two methods had not been conducted previously, and this investigation aimed to determine the effects of both the central and renewal leader methods, as well as the genotype, on sylleptic branching in apple nursery trees in response to repeated BA sprays. The genotype showed significant variation in the sylleptic shoot numbers (5.25–9.41), their average length (26.86–33.34 cm), and crotch angle (48.95˚–54.27˚) in response to the BA application. Among the genotypes, ‘Shireen’ produced the highest number of sylleptic shoots, whereas the opposite results were obtained in ‘Top Red’. Furthermore, irrespective of the genotype, the central leader method was found to be more effective than the renewal leader for the development of high-quality branched nursery trees. The central leader method not only significantly increased the number of sylleptic shoots on the tree but also positively affected their length, final tree height, and diameter. |

Assessing genetic variability and heritability in the F4 population of mutant Bioguma and Gando Keta local Indonesian sorghum [Sorghum bicolor (L.) Moench]Original PaperEndang Lestari, Karlina Syahruddin, Heny Herawati, Suarni Suarni, Moch Subechan, Suwarti Suwarti, Slamet Priyanto, Herniwati Herniwati, Diana WidiastutiCzech J. Genet. Plant Breed., 2025, 61(3):151-159 | DOI: 10.17221/15/2025-CJGPB This study examined the genetic variability, heritability, and genetic advance in the F4 generation of sorghum to enhance grain productivity. The study was conducted at Citayam Research Station, Depok Indonesia (March–September 2023), and evaluated 102 progenies of the F4 population from a Bioguma (a mutant line) × Gando Keta (a local variety) cross using an Augmented block design with four replications. The results of this experiment indicated that the F4 generation outperformed the Gando Keta grain yield components, but remained inferior to Bioguma. The yield traits were influenced by the non-additive gene action, with genetic factors playing a significant role in grain weight variation. The top 20% of F4 progenies exhibited improved yield characteristics, including thicker stems, larger panicles, and increased grain weight. |
Granular organic hydrosorbents increase water retention and resistance of boxwood seedlings during droughtOriginal PaperMarkéta Mayerová, Martin Stehlík, Tomá¹ ©imon, Petr Hutla, Ilona GerndtováHort. Sci. (Prague), 2025, 52(2):162-172 | DOI: 10.17221/72/2024-HORTSCI Sufficient available water in the soil is critical for plant growth, especially soon after planting. Water absorbed by organic hydrosorbents has the potential to reduce drought stress after planting and improve seedling survival. This research evaluates the effectiveness of granular organic hydrosorbents (GOH) in increasing soil-water retention in a pot experiment with boxwood (Buxus sempervirens L.) seedlings. The leaf chlorophyll content was also evaluated to determine plant growth. The following fertilisers were used: GOH 1 comprised 50% biogas products and 50% wheat straw, and GOH 2 combined post-harvest grain, legume and oilseed residues. The fertilisers were applied to the bottom of the pot or mixed with the soil. Both types doubled the initial water retention compared to the control. While the control water retention dropped below zero after 18 days without watering, retention in the fertilised treatments ranged from 0.5 to 0.76 L. Re-watering part of the trial after the 18 days then induced increased retention to the initial levels in all treatments and the control. However, the fertilised plant’s water retention was up to half a litre greater than in the control when the 62-day experiment ended. The effect of GOH application was also manifested in the chlorophyll content. In the no watering mode, the chlorophyll content was, on average, 20% and 13% higher in the treatments with GOH 1 and GOH 2 than in the control. In the watering regime, the application of GOH 1 and GOH 2 increased the chlorophyll content by an average of 31% and 26%, respectively. Finally, these trials established that the GOH applications significantly delayed boxwood-seedling drying and increased their water retention and chlorophyll content in unwatered and re-watered plants. |
Corn poppy (Papaver rhoeas L.) resistance to ALS inhibiting and 2,4-D herbicides in Moroccan and Tunisian rainfed wheat fieldsOriginal PaperZakia El-Mastouri, Pavlína Ko¹narová, Kateøina Hamouzová, Ezzedine Alimi, Josef SoukupPlant Soil Environ., 2025, 71(7):480-486 | DOI: 10.17221/45/2025-PSE Corn poppy (Papaver rhoeas L.) is one of the most problematic weed species, mainly in rainfed Moroccan and Tunisian cereal crops. The overuse of acetolactate synthase (ALS) inhibiting and/or auxinic herbicides led to the spread of corn poppies resistant to both chemical families in this region. In order to identify and understand the selection drivers of resistance, appropriate characterisation of the resistance profile is necessary. Two experiments were carried out: biological sensitivity tests with ALS inhibiting herbicides (tribenuron-methyl and florasulam) and auxinic herbicides (2,4-d) were carried out with populations sampled in the field where the herbicide failure was observed. Bioassay tests confirmed resistance in all studied populations with an average frequency of 75.13, 30.81, 33.17 and 11.52% with tribenuron, florasulam, 2,4-d and florasulam + 2,4-d, respectively. Corn poppy sampled from both countries exhibited similar frequencies within populations for each tested herbicide. The molecular analysis was conducted with next-generation sequencing (Illumina), allowing massive, precise and rapid sequencing regions of the ALS gene carrying resistance codons. Using this technology, ALS mutant alleles were found in all populations at frequencies ranging from 1.4% to 63.3%, with an average of 16.7%. This study highlights the need to elucidate resistance mechanisms to understand herbicide responses and develop effective strategies for managing resistant corn poppy in rainfed cereals as an essential step to maintain the effectiveness of these molecules as long as possible. |
Effect of Trichoderma harzianum against Fusarium oxysporum in resistant and susceptible tomato cultivarsOriginal PaperPatcharaporn Suwor, Manthana Mueangkhong, Praphat Kawicha, Thanwanit Thanyasiriwat, Suchila Techawongstien, Sanjeet Kumar, Wen-Shi Tsai, Somsak KramchoteHort. Sci. (Prague), 2025, 52(2):173-181 | DOI: 10.17221/126/2023-HORTSCI Fusarium wilt disease presents a substantial challenge to tomato production, especially in an open field environment. The peroxidase (POD) activity and total phenolic compounds (TPCs) play a crucial role in measuring the antioxidant capacity of plants. Understanding the variations in the POD and TPC levels during disease-induced stress becomes important for effectively managing Fusarium wilt and enhancing tomato production. This study investigates the impacts of Trichoderma harzianum inoculation through the root drip method on five tomato cultivars. It compares these cultivars to their non-treated counterparts when they are subjected to infection by Fusarium oxysporum f. sp. lycopersici (Fol). The results showed that the level of resistance to Fol is based on the specific tomato cultivar. Notably, ‘MT26’ exhibited the lowest disease severity index (DSI), indicating a strong response, whereas ‘CLN3682F’ showed notable susceptibility. Regarding the POD and TPC activity, its exhibition differed in compatibility with the response of each tomato cultivar to Fusarium wilt disease. The resistant cultivars increased the POD activity after the Trichoderma induction before the Fol inoculation, and this activity was further boosted when exposed to disease conditions. Consequently, enhancing the POD and TPC levels during the initial stages could potentially serve as a systemic defence mechanism of tomatoes against the Fusarium wilt disease. |
Gastric survival of lactic acid bacteria in probiotic-labelled products from the Turkish market: An in vitro studyOriginal PaperGizem Özlük, Gabriela KrausováCzech J. Food Sci., 2025, 43(5):344-351 | DOI: 10.17221/36/2025-CJFS The resilience of lactic acid bacteria (LAB) in commercial probiotic products remains a critical area of investigation, particularly regarding their capacity to survive the harsh gastric environment. Scientific guidelines indicate that at least 6 log CFU·g–1 of viable probiotics must reach the intestines to achieve therapeutic benefits, which often requires an initial concentration of 8–9 log CFU·g–1 in the product. However, national regulations may specify lower thresholds; for example, Turkish Food Legislation requires 6 log CFU·g–1 for probiotic products and 7 log CFU·g–1 for kefir products. This study evaluates the in vitro gastric survival of LAB in 20 probiotic-labelled foods and 5 supplements available in the Turkish market using a simulated gastric model. Results reveal that 75% of the marketed probiotic-labelled foods comply with their label claims. Additionally, 55% of the samples demonstrate LAB strains fully resistant to gastric acidity. Dairy-based products exhibit significantly better survival rates under simulated gastric conditions compared to supplements, highlighting their potential for enhanced therapeutic efficacy. |
Detection of heat-stressed chickens in poultry house based on deep network and optical flow vectors in the Fourier domainOriginal PaperNgo Quoc Viet, Thai YenRes. Agr. Eng., 2025, 71(4):189-199 | DOI: 10.17221/46/2025-RAE The productivity and quality of the entire flock are negatively impacted by heat stress in chickens, which can have major repercussions, particularly in crowded farming settings where diseases are easy to spread and hard to control. This study uses deep networks and optical flow to identify heat stress in chickens. The technique focuses on identifying obvious signs of heat stress, such as panting and open-mouth breathing in chickens. There are two phases to the suggested approach: (1) using a deep network to detect open-mouth breathing in chickens; (2) using the Gunnar Farnebäck algorithm to compute the optical flow vectors of the wattle, the breathing frequency is estimated in the Fourier domain for the detection of panting chickens. The proposed method was tested on the obtained dataset and demonstrated its ability to recognise heat-stressed chickens in crowded conditions, achieving an overall performance metric of 0.90 by integrating the results of both phases. The two-phase approach, which incorporates the open-mouth breathing behaviour and panting frequency, improves the efficiency and assures robust, reliable heat stress detection. |
A comparative applied analysis of six robotic-assisted weeding systems in sugar beetsOriginal PaperSonja I. Kimmel, Matthias Schumacher, Michael Spaeth, Markus Sökefeld, Oyebanji O. Alagbo, Alicia Allmendinger, Dionisio Andujar, Therese W. Berge (ORCID: 0000-0002-8780-Plant Soil Environ., 2025, 71(11):782-792 | DOI: 10.17221/335/2025-PSE Effective weed management is crucial in the critical period of sugar beet production, but often lacks sustainability and environmental protection. Recent advancements in sensor-based weed control systems have rendered the latter a realistic prospect, which demands detailed analyses, especially under suboptimal field conditions. The present study analysed six robotic-assisted weed control systems (RAWS) in three experiments on sugar beets in 2024, conducted under dry soil and high weed pressure. The experiments included sensor-based inter-row and intra-row hoeing, spot- and band-spraying and were compared to a broadcast herbicide treatment and an untreated control. Weed control efficacy (WCE) in the intra- and inter-row areas, as well as weed species composition and crop plant damage, were assessed after treatment. The data show that intra-row WCE of two hoeing robots (Farming GT® and Robovator®) equipped with selective intra-row blades achieved up to 80%, which was higher than the broadcast herbicide control with 67% WCE. In the inter-row area, Farming GT® robotic hoeing and ARA® spot-spraying resulted in more than 90% WCE, which was equal to the broadcast herbicide application. Weed species composition was not affected by the different RAWS. Crop plants were affected by all hoeing treatments with maximum non-lethal burial rates of 33%. The highest lethal uprooting of crop plants occurred after Farming GT® robotic hoeing, at 5.5% overall. The results demonstrate the great potential of robotic weeding to replace broadcast herbicide applications. |
Effect of harvest time on total phenolic and flavonoid contents and antioxidant capacities of two grape varieties from Trebinje vineyard areaOriginal PaperMersija Deliæ, Milenko Blesiæ, Fikreta Behmen, Anstasija Anðu¹iæ, Fahrudin Topèiæ, Senad MurtiæHort. Sci. (Prague), 2025, 52(4):304-312 | DOI: 10.17221/52/2025-HORTSCI The aim of this study was to analyse the effects of harvest timing on the total phenolic and flavonoid contents, in addition to the total antioxidant capacity in the berries of ‘®ilavka’ and ‘Vranac’ varieties grown in the Trebinje vineyard area. Grape samples for both varieties were collected at three distinct points during their ripening. The chosen harvest dates were set 10 days apart, and the optimal date for grape harvesting was determined by assessing the sugar content and titratable acidity present in the grapes. Total phenolics, total flavonoids and total antioxidant activity of grape samples were determined by the Folin-Ciocalteu method, aluminium chloride method, and ferric reducing antioxidant power assay, respectively. The total phenolic and flavonoid contents, along with the total antioxidant capacity in the ‘Vranac’ grape, increased from the first to the second harvest date, but a decline was noted at the third harvest. ‘®ilavka’ grape exhibited an increase in total phenolic and flavonoid contents, as well as total antioxidant capacity from the first to the second harvest date, with no decrease recorded by the third harvest. As expected, the red grape variety ‘Vranac’ contained higher levels of phenolics and flavonoids than the light-skinned grape variety ‘®ilavka’. |
The new EU Timber Regulation 2023/1115 and its legal implications for the Czech forestry and timber sectorReviewPetra Hlaváèková, Martin Cempírek, David BøezinaJ. For. Sci., 2025, 71(12):575-588 | DOI: 10.17221/82/2025-JFS Regulation (EU) 2023/1115 on deforestation-free products (EUDR) establishes a substantially revised legal framework that extends beyond the previous EU Timber Regulation (EUTR 995/2010) by integrating legality, sustainability, and traceability obligations. This article provides a legal and comparative assessment of the implications of the EUDR for the Czech forestry and timber sector. The methodological approach combines doctrinal interpretation of EU legislation, comparative analysis of national implementation models, and an examination of relevant case law. Experiences from selected EU Member States are used to illustrate institutional, technological, and administrative challenges linked to EUDR implementation. The results indicate that, although the Czech Republic has an established regulatory framework under Act No. 251/2025 Coll., effective compliance with the EUDR will require improved coordination among supervisory authorities and the development of a unified digital platform for submitting and verifying due diligence declarations. Evidence from other European countries shows that integrated monitoring systems and the use of third-party certification can enhance both efficiency and transparency. The study concludes that the successful implementation of the EUDR in the Czech context will depend on institutional capacity, digital readiness, and the ability of forest managers and traders to adapt to more stringent environmental and traceability requirements. |
Market entry strategy and export destination in the Spanish wine industryOriginal PaperRaul Serrano, Juan Ramón Ferrer, Silvia Abella, Vicente PinillaAgric. Econ. - Czech, 2024, 70(12):621-632 | DOI: 10.17221/107/2024-AGRICECON This paper analyses the market entry strategy of the Spanish wineries and their destination markets. For this purpose, channel adjustment was analysed. The novel aspect of this research is the use of exports on a winery level, basing the explanation of their export performance on a combination of internal decisions of the companies, and characteristics of the wine destination markets, in accordance with the purchasing patterns of their consumers. The results revealed the importance of strategic adjustment between winery and market destination, even though the importance of adjustment depends on the level of exports. Thus, channel adjustment is important for the probability of export and export intensity. |
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. |
