Effect of the pumpkin seed flour and pumpkin seed oil cake flour addition on quality of wheat breadOriginal PaperNatasa Lakic-Karalić, Ladislav Vasilišin, Staniša Latinović, Goran Vučić, Slavica Grujić, Božana Odžaković, Anastasija Tegeltija, Ivana ČolićCzech J. Food Sci., 2026, 44(1):35-44 | DOI: 10.17221/190/2024-CJFS Pumpkin seeds and their oil cake are often treated as by-products, but their composition and high nutritive and biological value makes them a promising material for nutritional enrichment of bakery products. The purpose of this study was to characterise pumpkin seed flour (PSF) and pumpkin seed oil cake flour (PSOCF), and evaluate the effects of their addition on the chemical composition including the fatty acid composition, textural parameters, sensorial characteristics and antioxidant activity of the wheat bread. Six experimental bread samples with 5, 10 and 15% of PSF or PSOCF added to wheat basic formulation, and a control wheat sample, were produced. Results indicated that addition of PSF and PSOCF led to higher ash, cellulose, protein, fat, total carotene and unsaturated fats content, which means that the experimental bread samples had a higher nutritional value. PSF addition had more positive effect on the textural characteristics and antioxidant activity of bread, than PSOCF addition. All bread samples (evaluated by 5-point scale multiplied with the coefficient of importance) had very high sensory quality (89.88–96.59% of maximal possible quality). The results confirmed that PSF and PSOCF are suitable for use in food industry for nutritional enrichment of wheat bread and related products. |

Performance of different banana varieties (Musa spp. AAA) under protected cultivation in terms of morphological, yield and quality characteristicssOriginal PaperSabriye Atmaca, Halil İbrahim Yolcu, Gökhan Erdoğan, Hakan Sert, Hamide GübbükHort. Sci. (Prague), 2026, 53(1):27-37 | DOI: 10.17221/51/2024-HORTSCI Recently, protected cultivation of bananas under subtropical conditions has gained popularity due to the impact of global climate change. Several factors influence the yield and quality of banana cultivation. Among these factors, variety plays an important role along with cultural practices. This study aimed to determine the performance of ‘Azman’, ‘Bango’, ‘Bonus’, ‘Grand Nain’, ‘Lider’, and ‘Paşa’ banana varieties in terms of morphological and yield characteristics under protected cultivation, as well as to elucidate the relationship between yield and factors affecting yield. The research was conducted between 2020 and 2022 in the Manavgat district of Antalya. The research findings showed that each morphological parameter examined varied significantly. However, the ‘Bango’ variety exhibited superior results in terms of finger circumference (13.23 cm), finger length (21.08 cm), bunch weight (39.33 kg), and yield per hectare (72 t/ha). Moderate to high-level phenotypic correlations were found between bunch weight and pseudo stem girth, pseudo stem height, number of fingers, finger weight, finger circumference, and finger length, with values of 0.544, 0.478, 0.326, 0.669, 0.581, and 0.543, respectively. Positive and significant phenotypic correlations were determined between finger length affecting export quality, bunch weight, finger weight, and finger circumference, with values of 0.543, 0.799, and 0.625, respectively. It can be concluded that the ‘Bango’ variety exhibited better results as compared to other varieties in terms of both yield and quality criteria. Additionally, positive phenotypic correlations were observed between bunch weight (which directly influences yield) and finger length (which affects export quality), as well as various morphological and pomological characteristics. |
Sustainable medicinal plant production – responses of Lamiaceae plants to organic acid elicitors spraying during environmental stress: A reviewReviewIsmail Mahmoud Ali Shahhat, Arbi Guetat, Salma Yousif Sidahmed Elsheik, Medhat Ahmed Abu-Tahon, Abdelrahman Talha Abdelwahab, Marwa Abdelfattah AwadPlant Protect. Sci., 2025, 61(2):110-151 | DOI: 10.17221/83/2024-PPS This article provides a review of recent studies on the extent to which the use of organic acid elicitors such as salicylic, jasmonic, humic and ascorbic acids has been successful in alleviating the exposure of Lamiaceae plants to unfavourable environmental conditions such as drought and salinity. Overall, the results concluded all organic acid elicitors enhanced the morphological and physiological characteristics of biochemical and secondary metabolite contents. These improvements have enabled plants of the Lamiaceae family to adapt to environmental stress conditions to some extent and survive, thus achieving sustainability in the production of plants of this family. It can be recommended to use salicylic acid in concentrations 0.5–2.5 mM, and it should not exceed it so as not to cause poisoning and disruption of the vital and physiological processes within the plant. In contrast, these plants have limited studies on the relationship between jasmonic acid/ascorbic acid and ascorbic acid. Since vitamins such as ascorbic acid are essential for plant metabolism and growth regulation, their effect on these plants remains unstudied at concentrations 2–10 mM under different abiotic stresses. Further research is needed to understand the impact of Nano-SA, JA, HA, ASA, and citric acid on Lamiaceae plants under various environmental stress conditions. Limited studies exist on the relationship between jasmonate/humic acid and Lamiaceae plants under abiotic stress. The Lamiaceae family needs more studies on adaptation to various environmental conditions and the toxicity of stimulants used to confront these conditions. This research contributes to improving agricultural practices in challenging environmental regions. |
Meta-analysis of fluorochrome concentrations to assess bull sperm quality by flow cytometry in 2021–2023ReviewFilipp Georgijevič Savvulidi, Martin Ptáček, Szabolcs Nagy, Luděk StádníkCzech J. Anim. Sci., 2023, 68(12):469-485 | DOI: 10.17221/152/2023-CJAS Flow cytometry (FC) is a very powerful method for the assessment of spermatozoa quality in multiple livestock species, including bulls. Nowadays, many flow cytometric tests are available for quality detection of bull sperm. These tests are based on fluorochromes (fluorescent tags or dyes) and the use of correct concentrations of fluorochromes is an essential aspect of the successful optimization of experimental methodology. Modern flow cytometers are much more affordable, such that spermatologists are now able to use FC methodology (and even image cytometry) in their studies. The present review aims to give a summary of current flow cytometric methodologies used to assess bull sperm quality by flow cytometry. Namely, we give here the concentrations of fluorochromes used in the studies related to bull sperm quality evaluation by flow cytometry published in the last three years (from 2021 to 2023). Importantly, in the present review, the concentration of fluorochromes is unified and presented using comparable molarity units. Furthermore, the rationale of each flow cytometric methodology for particular fluorescent tests, and the citation for the corresponding original methodology, are given. This review will help spermatologists shorten the time needed for the optimization of their flow cytometry methodology for the assessment of bull sperm quality. |

Decoupling of stomatal and mesophyll recovery drives photosynthetic resilience to water deficit in sugar beet: evidence from multiscale structural and functional traitsOriginal PaperYangyang Li, Zengyuan Tian, Jixia Su, Kaiyong Wang, Pengpeng Zhang, Hua FanPlant Soil Environ., 2026, 72(1):49-65 | DOI: 10.17221/564/2025-PSE Water deficit severely constrains sugar beet productivity by impairing photosynthetic capacity. However, the underlying structure-function mechanisms conferring photosynthetic resilience remain poorly characterised. This study investigates the temporal dynamics of photosynthetic limitations and structural adaptations in sugar beet during water deficit and subsequent rehydration. We found that water deficit significantly reduced the maximum net CO2 assimilation rate (ANmax) and the Rubisco carboxylation rate (Vcmax) by impairing CO2 diffusion and biochemical processes. The reduction in photosynthetic capacity is primarily and stably attributed to mesophyll limitation, while contributions from stomatal and biochemical limitations flexibly change with deficit degree and rehydration. Severe water deficit caused irreversible structural damage that hinders recovery even after rehydration, while moderate water deficit allows partial restoration of leaf and chloroplast function. Partial least squares structural equation modelling (PLS-SEM) demonstrated that CO2 diffusion was governed by the volume fraction of intercellular air space (fias, β = 0.28) and surface areas of the chloroplasts exposed to leaf intercellular air spaces (Sc/S, β = 0.35), with Sc/S indirectly influencing mesophyll conductance (gm) through fias mediation (β = 0.53). Severe water deficit caused irreversible fias reduction and chloroplast interface damage (59% cell volume loss). These findings establish that resilience to water deficit in sugar beet depends on mesophyll structural integrity, with fias and Sc/S as key modulators of gm recovery. The study advances understanding of stress recovery mechanisms in sugar beet and provides a framework for multiscale crop improvement in the context of climate change. |
Transcriptome analysis reveals differential gene expression in tomato under high-temperature stressYun Li, Xin Ye, Lingzeng Lv, Na ChenCzech J. Genet. Plant Breed., 2025, 61(3):160-179 | DOI: 10.17221/45/2025-CJGPB Tomato is a major global crop, extensively cultivated in China. However, the molecular mechanisms underlying its responses to high-temperature stress remain poorly understood. This study investigates these mechanisms by examining a heat-resistant tomato variety, Hm 2-2 (R), and a heat-sensitive variety, BY 1-2 (S), under high temperature (40 °C). Total RNA was extracted from samples taken at 0 and 24 h post-treatment, followed by RNA-sequencing (RNA-seq). Differentially expressed genes (DEGs) were screened based on the criteria of |log2 fold change| ≥ 2 and false discovery rate ≤ 0.05. Gene ontology (GO) function annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathway enrichment analysis were performed to explore the biological significance of these DEGs. The results revealed 6 038 upregulated and 2 866 downregulated DEGs in the R-0 (Hm 2-2 plants treated at 40 °C for 0 h) vs. R-24 (Hm 2-2 plants treated at 40 °C for 24 h) group and 5 297 upregulated and 3 920 downregulated DEGs in the S-0 (BY 1-2 plants treated at 40 °C for 0 h) vs. S-24 (BY 1-2 plants treated at 40 °C for 24 h) group, respectively. GO enrichment analysis indicated that the majority of DEGs were associated with biological processes, followed by cellular components and molecular functions. KEGG pathway analysis identified 130, 131, 89, and 115 regulatory (or altered) pathways in the R-0 vs. R-24, S-0 vs. S-24, S-0 vs. R-0, and S-24 vs. R-24 group comparisons, respectively. Notably, pathways related to protein processing in the endoplasmic reticulum and plant hormone signal transduction were significantly enriched, suggesting their critical roles in the tomato’s response to heat stress. Moreover, 156 transcription factors (TFs) implicated in heat stress response were identified, spanning various TF families such as MYB, AP2-EREBP, b-ZIP, bHLH, NAC, and WRKY. Quantitative RT-PCR analysis of 14 randomly selected DEGs validated the RNA-seq results confirming the reliability of the data. In summary, this study provides valuable insights into the molecular mechanisms of tomato’s responses to high-temperature stress, laying a crucial foundation for future research in this area. |
Interaction of seaweed metabolites with plants to enhance protection against biotic and abiotic stressesReviewBibi Aida, Deepak Kasote, Jisun Hyunsook Lee[Ahead of Print]CAAS Agricultural Journals, X:X | DOI: 10.17221/5/2025-PPS Biotic and abiotic stresses severely compromise economically important food crops' nutritional quality, growth, and yield. Conversely, the conventional reliance on chemical fertilisers and pesticides has generated substantial environmental and health risks, necessitating the development of sustainable alternatives. Seaweeds are rich sources of bioactive primary and secondary metabolites, and also promising natural biostimulants for enhancing plant resilience and productivity. Specific seaweed-derived metabolites function as molecular elicitors, mimicking pathogen-associated molecular patterns (PAMPs) and activating multi-layered plant defence mechanisms. This review aims to capture recent literature on the biological efficacy of seaweed extracts and their constituent metabolites, such as polysaccharides, phenolic compounds, and fatty acids, against diverse biotic stressors (e.g., bacteria, viruses, oomycetes, fungi (ascomycetes and basidiomycetes), nematodes, and herbivorous insect pests) and abiotic stressors (such as salinity, drought, extreme temperatures, and heavy metals). The biochemical, physiological, and molecular mechanisms by which seaweed-derived bioactive compounds modulate plant defence responses and stress tolerance pathways are also discussed in detail. In conclusion, seaweed extracts and derived metabolites show promising stress-type-specific effects against biotic and abiotic stresses through diverse mechanisms. However, field validation, dosage optimisation, and the discovery of novel bioactives are essential to harnessing their potential fully in sustainable agriculture |
Secondary antibody therapy outperforms corticosteroids in an ameliorating lipopolysaccharide-induced rat model of premature ovarian failureOriginal PaperAA Zaki, SM AlbarrakVet Med - Czech, 2026, 71(3):117-128 | DOI: 10.17221/66/2025-VETMED Premature ovarian failure (POF) is a significant cause of infertility and is often linked to autoimmune aetiologies. Lipopolysaccharide (LPS)-induced inflammation is a well-established model of autoimmune POF in rodents. Immunomodulatory treatments involving corticosteroids, frankincense, and targeted secondary antibodies have been hypothesised to mitigate the autoimmune response, reduce anti-ovarian antibody (AOA) levels, and restore ovarian function in an LPS-induced POF rat model. A POF model was established in female albino rats via the intraperitoneal injection of LPS. The rats were then divided into groups that received no treatment (LPS control), dexamethasone (DEX-treated LPS-treated rats), methylprednisolone (MP-treated LPS-treated rats), frankincense (Frankincense-treated LPS-treated rats), or secondary anti-ovarian antibodies (secondary Ab-treated LPS-treated rats) for 3 to 4 weeks. The serum levels of AOA, 17β-oestradiol, follicle-stimulating hormone (FSH), and luteinising hormone (LH) were assayed via commercial enzyme-linked immunosorbent assay (ELISA) kits. Ovarian tissues were examined histopathologically to assess structural damage and recovery. LPS induction successfully created a POF phenotype, as evidenced by significantly elevated AOA levels (P < 0.001), reduced 17β-oestradiol (P < 0.001), elevated FSH/LH (P < 0.001 and P < 0.05, respectively), and severe histopathological damage, including follicular atresia. All the treatments restored 17β-oestradiol levels. Secondary antibody therapy was most effective, normalising all hormonal parameters, significantly reducing AOA levels, and demonstrating complete histological recovery with healthy follicles and corpora lutea. MP potently suppressed AOA but paradoxically elevated FSH, without improving ovarian histology. DEX and frankincense showed intermediate efficacy, improving some hormonal and serological markers but failing to achieve full histological restoration. These findings demonstrate that targeted immunotherapy using secondary antibodies is superior to broad immunosuppression or anti-inflammatory treatment for restoring ovarian function in patients with autoimmune POF. While corticosteroids effectively reduce AOA titres, they may not reverse ovarian damage and can disrupt the hormonal balance. This underscores the need for precise, biomarker-guided therapies over nonspecific immunosuppression in patients with autoimmune ovarian insufficiency. |

Cleanup goals for petroleum-contaminated pastures according to oil density, concentration, and soil typeOriginal PaperJuan Pablo Montero-Vélez, Verónica Isidra Domínguez-Rodríguez, Randy H. AdamsPlant Soil Environ., 2025, 71(11):759-769 | DOI: 10.17221/339/2025-PSE The common 1% oil cleanup criterion was tested for pasture production according to oil type and concentration, in soil types frequently contaminated in southeastern Mexico. Reductions in aerial biomass of Brachiaria humidicola were measured over six months in soils contaminated with crude oils of varying grades (light, medium, heavy, and extra-heavy). Dose-response curves for heavy crude-contaminated soils showed acceptable criteria (90% pasture) of 0.71, 0.56, 1.23, ~0.20 and < 0.10% oil for an Arenosol, Vertisol, Gleysol, Fluvisol and an Acrisol, respectively. Generally, for all crude oils, the 1% level resulted in pasture reductions of ~20–70, ~25–60, ~50–65, and ~35–65% in the Arenosol, Vertisol, Fluvisol, and Acrisol, respectively. Still, in the Gleysol it was variable (reduction of ~10% to an increase of ~15%). Thus, the 1% oil cleanup criterion may be suitable for some soils with large amounts of smectite clays and organic matter (such as Gleysols). Still, for most soils, it may not be strict enough to prevent soil fertility deterioration, and soils with large amounts of non-smectite fines may be particularly impacted. Therefore, lower cleanup levels need to be considered, as well as low-cost regenerative agricultural practices to recover soil fertility in contaminated soils, when these cleanup levels are not achievable. |

Evaluation of changes in dry matter and nutrient content during the growth dynamics of silage maizeOriginal PaperAndrej Mitrík, Tomáš Mitrík, Iveta MaskaľováCzech J. Anim. Sci., 2026, 71(3):129-139 | DOI: 10.17221/172/2025-CJAS The aim of this study was to identify and quantify the relationships between the nutrient content and the DM (dry matter) content of various maize hybrids (Zea mays L.) in the dynamics of vegetative maturity and various soil-climatic growing conditions. Over the course of 7 growing seasons (years), a set of 1 972 samples of whole silage maize plants consisting of 206 different hybrids grown in two contrasting regions (lowland and foothill areas) was analysed. The focus was on DM content and the content of key energy nutrients (WSC – water soluble carbohydrates, starch, NDF – neutral detergent fibre) and their interactions. Results show that the transformation of WSC into starch has four key points: (i) it begins at a DM content of 150 g/kg; (ii) it peaks at a DM content of approximately 235 g/kg; (iii) it begins to decrease significantly from a DM content of 300 g/kg; and (iv) it practically stops rapidly after exceeding a DM content of 350 g/kg. In the dynamics of vegetative development of maize plants, the DM content is very closely related to the WSC content (R2 = 0.728) and the starch content (R2 = 0.873). With the gradual increase in vegetative maturity and DM content in maize plants, the transformation of WSC into starch dynamically increases. These characteristics, with small deviations, were also confirmed at different levels of evaluation (all analyses, regions, seasons and individual hybrids). These results show that a DM content of 300 g/kg to 350 g/kg can be considered the optimal harvesting window for maize ensiling and the optimal phase of silage maturity for whole maize plants, because once the DM content exceeds 350 g/kg; the transformation of WSC into starch stops and the drying phase of plants begins. |

Exogenous proline enhances salt tolerance in wheat: regulating osmolytes, hormonal balance, antioxidant defence, and yield performanceOriginal PaperAbeer Hamdy ElhakemPlant Soil Environ., 2025, 71(4):278-292 | DOI: 10.17221/97/2025-PSE This study investigates the impacts of exogenously applied proline (Pro, 10 mmol/L) on the growth and productivity of wheat plants in saline environments. The findings indicated that increased NaCl concentrations, 60 and 120 mmol/L, further depressed the shoot and root growth parameters and flag leaf area. However, the Pro treatment ameliorated salt stress and improved all growth parameters, reducing the magnitude of such growth inhibitions compared to nontreated plants. It also enhanced the organic osmolyte accumulation, including Pro, total soluble sugars, and total soluble protein, implicated in osmotic balance and cell protection under stress. Furthermore, supplementing Pro improved ionic balance through a reduction in Na accumulation and an enhancement in the uptake of K, Ca, and Mg, thus mitigating the negative effects of salinity on nutrient availability. Pro treatment affected phytohormone levels, especially increasing auxin and gibberellins while decreasing abscisic acid under salt stress. Antioxidant enzymes such as catalase, superoxide dismutase, ascorbate peroxidase, and glutathione reductase, as well as nonenzymatic antioxidants like ascorbic acid and glutathione, were also enhanced by Pro, thereby protecting the plants against oxidative damage. Moreover, it was noticed that Pro treatment substantially improved all yield attributes of wheat plants, such as plant height, spike length, no. of spikelets/main spike, grain no./main spike, grain fresh and dry weights, and grain yield/plant through attenuation of the negative impact of NaCl. In this regard, Pro application appears to be a very promising approach toward mitigating the adversities of salinity in agriculture, especially in crop productivity in saline environments. |

The effect of artificial reduction of the somatic cell count, as a violation of authenticity, on milk quality indicatorsOriginal PaperOto Hanuš, Hana Nejeschlebová, Veronika Legarová, Lucie Kejdová-Rysová, Jan Říha Jr., Eva Samková, Gavin Thompson, Irena Němečková, Marcela Klimešová (email: marcela.vyleteCzech J. Anim. Sci., 2025, 70(8):319-334 | DOI: 10.17221/90/2025-CJAS The somatic cell count (SCC) in raw milk is an important indicator of health and hygienic quality. Artificial reduction of the SCC (ARSCC) in milk, for the apparent improvement of milk quality for commercial reasons, is an undesirable phenomenon and a violation of authenticity both in the factual sense and legislatively. Analytical methods need to be developed to identify ARSCC as well as to assess the effects that ARSCC may have on milk. The aim of the work was to quantify the effects of ARSCC on cow’s milk as a food raw material. The results presented are some of the first on the given problem. Raw bulk tank cow milk was sampled in two experiments, each time for the whole year (2021–2022 and 2023–2024, n = 66 and n = 53, respectively) from herds of Czech Fleckvieh and Holstein cows, 1 : 1. ARSCC in experiment 1 (n = 66) slightly reduced the fat content, in experiment 2 (n = 53) it did not, otherwise the milk indicators with the exception of SCC were almost (1) and completely (2) identical. All samples were negative for the presence of inhibitory substance residues. ARSCC under the specified technological conditions reduced SCC (1) from 772 ± 906 103/ml to 376 ± 630 103/ml, by –51.3% (P < 0.001) and (2) from 592 ± 798 103/ml to 304 ± 468 103/ml, by –48.5% (P < 0.001). Under these circumstances, the milk fermentation ability improved (1) from 28.52 ± 4.72 °SH to 31.0 ± 4.65 °SH, by 8.66% (P < 0.001) and (2) from 32.51 ± 2.61 °SH to 33.80 ± 2.88 °SH, by 3.97% (P < 0.001). Curd firmness was better for SCC ≤ 400 103/ml compared to higher SCC by 5.26% (P < 0.001). Nevertheless, it is not possible, for hygienic and health reasons, to allow such milk for human consumption and it is necessary to find effective identification analytical methods for ARSCC. |

The impact of periodic waterlogging on biochemical characteristics and mineralization of soil organic carbon in straw-return farmlandOriginal PaperYunxi Peng, Wenyu Shi, Ningning Zhao*Soil & Water Res., 2025, 20(2):131-141 | DOI: 10.17221/149/2024-SWR Periodic waterlogging is more common due to more frequent extreme precipitation but its impact on soil organic carbon (SOC) loss is obscure in straw-return farmland. We compared soil properties and biochemical characteristics of SOC (compositions of non-cellulosic and amino polysaccharides) in adjacent periodic waterlogged farmland (PWF) and non-waterlogged farmland (NWF) in a semi-humid warm temperate region. SOC mineralization was also measured at 60% (aerobic) or 100% (anaerobic) of field capacity at 25 °C for 82 days. The negative effect of periodic waterlogging on SOC contents and soil aggregate stability were observed in the 20–80 cm depth but were offset in topsoil (0–20 cm) due to straw-return. Periodic waterlogging increased the non-cellulosic sugar content and amino sugar content in SOC and the mass ratio of (galactose plus mannose) to (arabinose plus xylose) at 40–80 cm depth except at 0–40 cm depth. By the end of 82 days’ incubation, when aeration status changed from anaerobic to aerobic conditions, total C loss as CO2 increased similarly (123.9%) in PWF and NWF soils in the top 40 cm, but more C loss occurred under PWF than under NWF (78.9% vs. 46.9%) in the 40–80 cm depth, which was probably ascribed to its higher non-cellulosic sugar and amino sugar content. Our result emphasized the importance of straw-return for maintaining soil quality under periodic waterlogged farmland. |
Efficacy of a new ready-to-use PCV2 and Mycoplasma hyopneumoniae vaccine under field conditionsOriginal PaperP Trampus, A Csagola, T Szalai, N Palmai, A Toth, N Terenyi, Z Nagy, NA Szeplaki, G Somogyi, E Rausch, Z Penzes, R KrejciVet Med - Czech, 2025, 70(11):401-407 | DOI: 10.17221/25/2025-VETMED Coinfection of porcine circovirus type 2 (PCV2) with Mycoplasma hyopneumoniae (M. hyo) causes major worldwide economic losses within the swine industry. This study aimed to assess the safety and efficacy of a single dose of a bivalent vaccine containing PCV2d and M. hyo antigen (Cirbloc® M Hyo) under field conditions. Two studies were performed under the GCP (Good Clinical Practice) requirements on farrow-to-finish farms in Hungary and Cyprus. On both farms, the presence of both PCV2 and M. hyo infection was demonstrated. For both studies, safety parameters were observed and measured from inclusion at 21 (±3) days of age until 14 days after vaccination. Efficacy parameters were observed and measured from inclusion until slaughter. Administration of the vaccine was safe in both studies, as no general, immediate, or local reactions were observed. The efficacy of the vaccine was confirmed in both studies as the following parameters were significantly reduced in the vaccinated groups compared to the control groups: viraemia, faecal shedding, viral load in lungs and in all collected lymphoid tissues, M. hyo-specific lung lesions, and average daily body weight gain. These results collectively support the vaccine’s potential as an effective tool for disease control. |

Effect of vatinoxan co-administered with medetomidine on intraocular pressure and pupil diameter in healthy dogsOriginal PaperP Rauser, M Mrazova, A Sabatova, K JiraskovaVet Med - Czech, 2025, 70(12):427-431 | DOI: 10.17221/47/2025-VETMED Medetomidine, an alpha-2 adrenoreceptor agonist, is used for sedation. This study aimed to determine the influence of the alpha-2 adrenoreceptor antagonist vatinoxan, co-administered with medetomidine, on healthy dogs’ intraocular pressure (IOP) and pupil diameter (PD). A prospective, randomised, masked clinical study was performed. A total of 40 conscious dogs were allocated to one of two groups: medetomidine 0.01 mg/kg with vatinoxan 0.2 mg/kg intravenously (MV-group, n = 20) or medetomidine 0.01 mg/kg intravenously (M-group, n = 20). The IOP, PD, heart rate, and mean arterial pressure were measured prior to baseline and 5, 10, and 20 min after drug administration. Data were analysed using one- and two-way repeated measures ANOVA or their non-parametric equivalents (P < 0.05). No significant differences in IOP within or between groups were recorded. In the MV-group, PD remained unchanged compared to baseline. In the M-group, PD significantly (P = 0.007, P < 0.001, P < 0.001) decreased compared to baseline at all observation times. PD was significantly (P = 0.010, P < 0.001, P < 0.001) smaller in the M-group at all observation times compared to the MV-group. Vatinoxan co-administered with medetomidine, as well as medetomidine alone, did not significantly influence IOP. Vatinoxan with medetomidine did not affect PD, while medetomidine alone significantly reduced it. |

Genotypic variation in physiological, biochemical, and transcriptional responses to drought stress in spring barley at an early growth stageOriginal PaperŠarlota Kaňuková, Marcela Gubišová, Martina Hudcovicová, Jozef Gubiš, Katarína OndreičkováPlant Soil Environ., 2025, 71(12):905-922 | DOI: 10.17221/406/2025-PSE Drought is a major abiotic stress limiting barley (Hordeum vulgare L.) productivity. We evaluated 17 spring barley genotypes at the early leaf development stage under controlled laboratory conditions with optimal and drought treatments, integrating physiological, biochemical, and molecular traits. Drought reduced relative water content (–1.3% to –3.2%), plant height (–14.7% to –29.6%), and dry biomass (–2.3% to –24.9%), while inducing strong proline accumulation (+23.6% to +454%) and pigment loss (chlorophyll a –10.1% to –79.5%; carotenoids –6.2% to –70.9%). Principal component and discriminant analyses identified plant height and chlorophyll a as the most reliable discriminators, whereas relative water content was less predictive of the species. Multivariate stratification separated tolerant (Argument, Exalis, Slaven, Malz, Valis), intermediate (Laudis 550, Tango, Kompakt, LG Belcanto, SK Levitus), and sensitive (Kangoo, LG Tosca, LG Flamenco, Karmel, Bojos, Nitran, Tadmor) groups of genotypes. Gene expression profiling of 12 genotypes revealed a modest induction of HvABF2 (1.77-fold), moderate upregulation of HvSOD1 (1.82-fold) and HvAPX1 (2.28-fold), and the strongest response in HvP5CS (3.29-fold), which did not consistently correlate with tolerance. Tolerant genotypes combined growth stability, pigment retention, and moderate osmotic adjustment, whereas sensitive genotypes relied on excessive proline accumulation, resulting in severe pigment and growth penalties. Overall, drought tolerance in barley at the early growth stage emerged from the coordinated regulation of growth, photoprotection, and stress-gene activation, providing a foundation that can guide the selection of genotypes for subsequent validation under field conditions and future breeding programmes. |
Optimising plastic-film mulching under drip irrigation to boost maize productivity through enhanced water and fertiliser efficiency in sub-humid regionsOriginal PaperXiaodong Bo, Fuqi YaoPlant Soil Environ., 2025, 71(7):509-523 | DOI: 10.17221/213/2025-PSE Global food security is increasingly threatened by the vulnerability of agricultural systems to climate variability, especially in sub-humid regions. Northeast China, a major maize-producing region, experiences low spring temperatures and erratic rainfall, which have prompted the widespread adoption of plastic-film mulching (PFM) combined with drip irrigation. However, systematic evaluations of how different PFM patterns affect crop productivity and resource use efficiency remain limited. This study systematically evaluated three PFM strategies – full ridge-furrow mulching (FM), ridge mulching (RM), and no mulching (NM) – in combination with 240 kg N/ha and a zero-nitrogen control under drip irrigation to determine their effects on maize (Zea mays L.) yield, water use efficiency (WUE), and nitrogen utilisation. Field experiments over two consecutive growing seasons assessed crop growth, dry matter (DM) accumulation, nitrogen dynamics, grain yield, and related efficiency parameters. Both FM and RM significantly enhanced early maize growth. At the seedling stage, FM and RM increased plant height by 43.0% and 40.1%, and leaf area index (LAI) by 141.4% and 120.4% over NM, respectively. During the same stage, DM accumulation increased by 228.9% (FM) and 224.9% (RM). These improvements reflected favourable soil hydrothermal conditions under PFM. Before heading, PFM treatments increased pre-anthesis DM accumulation by up to 19.6%, and at maturity, FM and RM raised DM by 6.1% and 5.1% over NM. PFM significantly improved grain nitrogen accumulation, with FM and RM increasing it by 31.0% and 26.9% over NM, respectively, and nitrogen harvest index (NHI), with FM and RM increasing it by 6.8% and 6.1% over NM, indicating enhanced nutrient translocation to grain. PFM also improved grain yield, with FM and RM increasing it by 15.0% and 13.5%, WUE by 17.2% and 15.7%, and nitrogen partial productivity by 16.8% and 14.1%. No significant differences in yield or WUE were observed between FM and RM. Fertilisation consistently enhanced these benefits without changing the relative efficiency ranking of treatments. Notably, the advantages of mulching diminished after the heading stage as temperature and rainfall increased. PFM (both FM and RM) under drip irrigation improves maize yield, water use, and nitrogen efficiency in sub-humid regions. This integrated practice offers a scalable and sustainable strategy to increase maize productivity and resource efficiency, supporting food security in regions facing similar climatic challenges. |
