Cytospora tristicha (De Not.) Mlèoch comb. nov., a lesser-known pathogen of wild rosesOriginal PaperPatrik Mlèoch, Michaela SedláøováPlant Protect. Sci., 2025, 61(1):56-65 | DOI: 10.17221/122/2024-PPS Stem canker of Rosa pendulina, collected in south-eastern Switzerland (canton of Graubünden) in August 2022, was studied in details. The causal agent of the disease was first identified as Valseutypella tristicha (Valsaceae, Diaporthales, Ascomycota) based on microscopic characteristics. The subsequent molecular analysis classified it into the genus Cytospora and indicated that it is identical with C. rosicola, described from China in 2020 based on the molecular data, however, V. tristicha is an older name than C. rosicola, so this has priority. Thus, a new combination of the name is proposed for this fungus. |
Study on the geographical origin and characteristic differential components of Qianbei Ma lamb based on rapid evaporative ionization mass spectrometryOriginal PaperJi Zhang, Rui Hou, Yuhang Luo, Xiaohong Zhang, Hong Luo, Lei Ling, Liping XiangCzech J. Food Sci., 2025, 43(1):59-70 | DOI: 10.17221/159/2024-CJFS A rapid evaporative ionization mass spectrometry (REIMS) method combined with intelligent knife (iKnife) method was developed to explore the geographical origin and characteristic differential components of Qianbei Ma lamb. The REIMS conditions were initially refined, with the cauterization duration of 3 seconds, and the auxiliary solvent flow rate set to 100 μL·min–1 to prevent duplication. A database model was created from raw data through the proposed principal component analysis-linear discriminate analysis (PCA-LDA) in Live ID software, successfully applied to identify samples from 5 provinces in China and the real-time reliable identification rate with confidence higher than 99%. The obtained data by REIMS were used to establish the multivariate statistical models which using orthogonal projection to latent structures discriminant analysis (OPLS-DA), provided strong the discrimination power between composition and content changes of 16 specific ions such as m/z 726.3952 and m/z 744.4050, etc., including fatty alcohols, fatty acids and phosphatidylserines in mutton of different origin and the model displayed validation [R2(Y) = 0.968, Q2 = 0.924]. |
Growth and yield responses of maize, beetroot, and quinoa to salinity and straw mulchingOriginal PaperChau Thi Nhien, Cao Dinh An Giang, Brooke Kaveney, Jason Condon, Tran Duy Khanh, Dang Duy Minh, Nguyen Viet Long, Nguyen Van Loc, Chau Minh KhoiPlant Soil Environ., 2025, 71(10):681-694 | DOI: 10.17221/317/2025-PSE Vietnam’s Mekong River Delta (MRD), where rice is the dominant crop, is increasingly impacted by salinity intrusion, highlighting the need for alternative cropping options. This study evaluated the growth and yield performance of quinoa, beetroot, and maize under three irrigation salinity levels (0, 2 and 4 g/L), with and without rice straw mulch (7 t/ha), in greenhouse conditions representative of the MRD dry season. Agronomic traits, physiological parameters, and changes in soil, including electrical conductivity (ECe), soluble sodium (Sol-Na+), and exchangeable sodium percentage (ESP), were assessed. Results showed that quinoa demonstrated the greatest salinity tolerance, maintaining stable growth and yield under 4 g/L saline irrigation and soil ECe exceeding 15 dS/m. Beetroot’s yield was not significantly different under 2 g/L saline irrigation with straw mulching. Maize was highly sensitive to salinity and environmental stress, failing to complete its growth cycle under high heat and humidity, even in non-saline conditions. Across treatments, rice straw mulching significantly reduced soil ECe, Sol-Na+, and ESP, and improved crop performance under saline irrigation. Overall, quinoa and beetroot, especially when combined with mulching, offer promising alternatives for dry-season cropping in saline-prone areas of the MRD. In contrast, maize cultivation requires improved soil and environmental management under such conditions. |
Study of the genetic potential of autochthonous populations of perennial ryegrass (Lolium perenne L.) for use in breeding purposesOriginal PaperMarina Antic, ®eljko Lakiæ, Branislav Raduloviæ, Vera PopoviæCzech J. Genet. Plant Breed., 2025, 61(3):128-137 | DOI: 10.17221/21/2025-CJGPB The testing and evaluation of native populations of perennial ryegrasses (Lolium perenne L.) collected from the Republic of Srpska, Bosnia and Herzegovina were conducted from 2020 to 2022 at experimental fields and laboratories of the Institute for Genetic Resources and the Agricultural Institute of the Republic of Srpska in Banja Luka. Six native populations (labelled G1–G6) and two cultivars, Esquire and Tivoli (labelled G7 and G8), were analysed in this study. The following traits were examined: the plant height (cm), number of generative stems per plant, inflorescence length (cm), number of spikes per inflorescence, seed mass per inflorescence (g), and seed yield per plant (g). The results showed that all the native populations exhibited higher average plant heights compared to the Esquire standard (G7). Population G2 had the highest average number of spikes per inflorescence (26.8), while population G4 achieved the greatest average inflorescence length (27.7 cm). Statistically significant differences in the inflorescence length were observed between populations G2, G3, G4, and G6, compared to the standards G7 and G8 (Esquire and Tivoli). The genotype and year had a significant impact on the seed yield per plant. The average yield ranged from 32.4 g (G7) to 53.4 g (G4). The seed yield per plant showed a strong positive correlation with the number of generative stems per plant, the inflorescence length, and the number of spikes per inflorescence. The native populations G4 and G5 achieved significantly higher seed yields per plant compared to the other populations and may serve as highly valuable material for breeding programmes. |
Comprehensive protection of tomato photosystem under cold stress by Streptomyces sp. TOR3209Original PaperJia Ma, Jieli Peng, Nan Jia, Xu Wang, Yuxi He, Entao Wang, Dong Hu, Zhanwu WangHort. Sci. (Prague), 2025, 52(3):261-271 | DOI: 10.17221/90/2024-HORTSCI The plant growth-promoting rhizobacterium Streptomyces sp. TOR3209 induces plant tolerance in a wide range of stress conditions. However, the protection of photosystem under cold stress has not been fully understood. Here we reported that the photochemistry activity of photosystem II (PSII) was increased in tomato plants receiving TOR3209 treatment, including the maximum quantum efficiency of PSII photochemistry (Fv/Fm), PSII operating efficiency (ΦPSII), PSII maximum efficiency (Fv’/Fm’), and non-photochemical quenching (NPQ). Microscopic study revealed that the integrity of chloroplast structure was greatly improved by TOR3209, which was damaged at low temperature. Moreover, TOR3209 treatment resulted in good protection on leaf stomatal and guard cell size. In response to TOR3209 treatment, the intercellular CO2 concentration (Ci) and stomatal limitation values (Ls) were decreased while the mesophyll conductance (gm) and chloroplast CO2 concentration (Cc) were increased. The carotenoid content in TOR3209-treated tomato was accumulated at a higher level, which was involved in photoprotection and biosynthesis of abscisic acid (ABA), as well as the increased amounts of ABA in the leaves were subsequently verified in the plants treated with TOR3209. These results demonstrated that TOR3209 treatment comprehensively protected tomato photosynthesis at low temperatures. |
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. |
Mechanized tree planting in Nordic forestry: simulating a machine concept for continuously advancing site preparation and plantingShort CommunicationJussi Manner, Back Tomas ErssonJ. For. Sci., 2021, 67(5):242-246 | DOI: 10.17221/203/2020-JFS As labour for manual tree planting becomes scarcer, regeneration costs are steadily increasing in Nordic forestry. Today's intermittently advancing tree planting machines provide excellent silvicultural results, but are expensive to operate because of poor productivity. In contrast, continuously advancing planting machines, thanks to high productivities, are increasingly being regarded as a solution to these runaway regeneration costs. The Silva Nova was a historical, continuously advancing tree planting machine with high productivity. However, Silva Nova's weaknesses included high labour costs (it required two operators) and the random nature of how it chose planting spots. In contrast, SuperSilva, a purely conceptual modernisation of Silva Nova, involves both automation and microsite identification to make the machine more efficient. We used discrete-event simulation to analyse the stocking rate and spatial distribution of tree planting with SuperSilva. The simulation results showed that introducing sensors for identifying suitable microsites will allow continuously advancing planting machines (like SuperSilva) to plant seedlings in a numerically and spatially adequate manner on moraine soils. Hence, these sensors will increase the competitiveness and versatility of tree planting machines. Unfortunately, such reliable and robust sensor technology (unaffected by a wide variety of operating conditions) is not yet commercially available. |
Characterization of carotenoid profiles and presence of functional markers in sub-tropical maize (Zea mays L.) inbred linesOriginal PaperPeter Amoah, Victor O. Adetimirin, Bismark Anokye, Oluyinka J. llesanmi, Nnanna Unachukwu, Elisabeth Ivania AporvaCzech J. Genet. Plant Breed., 2025, 61(2):86-99 | DOI: 10.17221/143/2024-CJGPB Biofortification provides a sustainable, pragmatic strategy to address the lack of vitamin A and the associated health complications. The objectives of the study encompassed the quantification of the carotenoid content of 147 maize inbred lines, the identification of variable regions within the ZEP1 gene, the correlation of these observed variances in the presence of this gene with carotenoid content, and the identification of lines harbouring the favourable alleles of the crtRB1 gene. The observed correlations among the carotenoids synthesised by distinct branches of the biosynthetic process were both significant and positive. Utilising gel-based genotyping, 24 lines with contrasting carotenoid profiles were selected, evaluated and sequenced. Analysis of the variation in the sequence classified these lines based on their similarities to give 8 allele groups. The findings highlight that inbred lines both group 1 and group 8 exhibited significant associations with the carotenoid content of the lines. Specifically, ZEP1_7852, a discernible variation belonging to group 8, was found to be significantly associated with zeaxanthin content and total carotenoid content. Furthermore, 25 lines were found to have provitamin A content above 15 μg/g, harbouring the favourable alleles of the crtRB1 gene using KASP SNP zm0016. These lines can serve as parents for source populations and hybrids, leading to the further enhancement of provitamin A in maize. |
Monitoring surface water pollution in Algeria using database indicesOriginal PaperOuahiba Bouchama, Lounes AmarSoil & Water Res., 2025, 20(1):43-51 | DOI: 10.17221/83/2024-SWR This study investigated how remote sensing techniques can pinpoint pollution in surface water areas. Researchers focused on the municipalities of Boumerdes, Corso, and Tidjalabine in Algeria’s Boumerdes province. The team used geographic information systems (GIS) to analyse pollution levels and their spatial distribution. Specifically, they employed the Normalised Difference Vegetation Index (NDVI) to identify areas teeming with biodiversity and healthy vegetation. Furthermore, the compactness index provided insights into the overall evolution of the drainage network. This data proved invaluable in identifying areas likely impacted by pollution. Our study is part of a scientific approach to detecting, monitoring, and intervening in water pollution. The core objective was to develop an alternate approach to protecting productive farmland and populated areas by mitigating pollution in these susceptible zones. The NDVI and compactness index, along with their associated database, hold significant promise for environmental preservation efforts. This spatial procedure effectively maps the spatial temporal distribution of pollutants, providing targeted management strategies. The method’s user-friendly nature makes it easily applicable in other African countries. |
Effects of exogenous 2, 4-epibrassinolide and its inhibitors on the seed setting and yield of Tartary buckwheatOriginal PaperPeiuyn He, Huangdanni Ran, Kaifeng HuangPlant Soil Environ., 2025, 71(3):161-170 | DOI: 10.17221/669/2024-PSE The aim of this study was to evaluate the effects of exogenous 2, 4-epibrassinolide (EBR) on the yield of Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.). A 2-year field experiment was conducted on Tartary buckwheat (cv. Jinqiao 2) with different concentrations (0, 0.1, 0.5, 1.0, and 2.0 mg/L) of EBR and brassinolide (BRZ, inhibitor of brassinolide synthesis). The seed setting rate, agronomic traits, and yield initially increased and then decreased with an increase in the EBR application rate. The seed setting rate, agronomic traits, and yield decreased gradually with an increase in BRZ concentration, and yield was the lowest at 2.0 mg/L. The appropriate application of exogenous EBR could promote the increase of Tartary buckwheat yield. Compared with 0 mg/L (control), the 0.1, 0.5, and 1.0 mg/L treatments increased yield by 13.53, 32.73, and 7.08%, respectively, while the high-concentration treatment (2.0 mg/L) decreased by 4.13%. In conclusion, the appropriate concentration of EBR treatment (0.5 mg/L) delayed the senescence of Tartary buckwheat by increasing its root activity and the activity of antioxidant enzymes in leaves. Simultaneously, it increased the chlorophyll content of Tartary buckwheat leaves, enhanced photosynthesis, increased nonstructural carbohydrate content, and augmented the "source," increasing the seed setting rate and yield of Tartary buckwheat. This concentration is recommended for use in the production of Tartary buckwheat. |
Particle motion in mixed flow dryers: The effect of the wall inclination angle and frictionOriginal PaperAdrienn Bablena, János Beke, István KepplerRes. Agr. Eng., 2025, 71(1):50-59 | DOI: 10.17221/51/2024-RAE In Europe, the weather patterns require harvested grain crops to be dried before storage to prevent significant quality loss. The uneven movement of grains inside the drying equipment is a key issue affecting the drying process, causing under- or over drying the harvested crops and thus leading to quality degradation and ultimately to financial losses. To characterise the unevenness of material flow, we introduced a dimensionless displacement ratio. This dimensionless parameter was suitable for comparing the uniformity of the material movement processes within the dryer. Using experimental investigations and numerical simulations, we determined the effect of the lamella inclination angle, the friction between the grain-wall and grain-grain on the uniformity of the flow. The linear functions approximating the quantitative relationships were determined in all the cases. Our findings indicate a significant variation in the displacement ratio ξ corresponding to different lamella inclination angles and friction values demonstrating that the discrete element modelling approach provides further opportunities for determining the optimal operating parameters of mixed flow dryers. |
The path to smart farming: Profiling farmers' adoption of technologies in TürkiyeOriginal PaperHuseyin Tayyar Guldal, Hasan Sanli, Metin TurkerAgric. Econ. - Czech, 2025, 71(5):229-241 | DOI: 10.17221/401/2023-AGRICECON This study investigates the characteristics associated with the adoption of smart farming technologies in Turkish agriculture. By surveying 325 farmers across six regions in Türkiye, the research identifies key attributes influencing adoption patterns. Four distinct profiles emerge: technology users, non-users, young educated female farmers, and traditionalists. Exploratory findings from Multiple Correspondence Analysis (MCA) indicate that attributes such as agricultural insurance, credit utilisation, knowledge of smart farming systems, and tractor ownership are commonly observed among technology users. Ordinal logistic regression further quantifies these associations, highlighting the significant role of financial accessibility and knowledge dissemination in shaping adoption likelihoods. Non-users, on the other hand, are characterised by smaller landholdings, lack of credit use, limited awareness, and absence of tractor ownership, reflecting structural barriers to adoption. Tailored financial solutions and shared machinery parks could help address these challenges. Empowering young, educated women farmers, identified as a key demographic for innovation, offers an opportunity to catalyse broader technology adoption. By addressing knowledge gaps and fostering inclusive policies, this study provides actionable insights to accelerate the technological transformation and sustainability of Türkiye's agricultural sector. |
Toxicity of oxalic acid and its toxic effect on antioxidative enzymes in honey bee larvaeOriginal PaperT Majchrak, M Ratvaj, L Sabova, J Toporcak, L MolnarVet Med - Czech, 2025, 70(7):261-271 | DOI: 10.17221/18/2025-VETMED The production of food of plant origin is critically dependent on the pollination ability of honey bees, whose health has been deteriorating for a long time, and whose population is declining. In our in vivo experiment on a honey bee brood at the 4-day larval stage, we tested the following concentrations of oxalic acid: 0% (control – applied distilled water), 0.87%, 1.75%, 3.5% and 7%, corresponding to doses of 0 mg, 2.61 mg, 5.25 mg, 10.5 mg, and 21 mg of oxalic acid per dm2 of honeycomb with the brood. The LC50 values (72 h) ranged between 3.17% and 3.33%. The different LC50 values obtained resulted from three different methods used to calculate this indicator. The therapeutic index (TI) of oxalic acid was set to be 1.1, indicating a high risk to the honey bee brood. We observed an increased gene expression for the detoxifying enzyme glutathione-S-transferase (GST), but did not detect an increased gene expression for superoxide dismutase (SOD1 and SOD2), which protects the organism from oxidative stress. A decrease in gene expression was observed for prophenoloxidase and hymenoptaecin, while defensin and lysozyme did not show significant changes. These results emphasise the need for the accurate dosage and application of oxalic acid in the treatment of varroosis. |
Himalayan fir growth in central Bhutan reflects variability in temperature and precipitationOriginal PaperJiøí Lehejèek, Gabriel Vávrù, Sangay Wangchuk, Miroslav Svoboda, Katrien BoonenJ. For. Sci., 2025, 71(10):516-524 | DOI: 10.17221/58/2025-JFS Mountain ecosystems, especially those at the highest altitudes, are sensitive to current climate change. Proxy archives may provide an insightful tool to better understand ongoing changes and evaluate future scenarios. Trees have traditionally been used as such archives, as they often respond sensitively to environmental change. Thus, we studied tree-ring records of forest-line species Abies densa Griff. growing in the Eastern Himalayas, central Bhutan, to evaluate the effect of climate on the growth of this species. The annual chronologies were generated using standard dendrochronological methods and then compared with climatic data from the CRU TS database. The results demonstrate a negative effect of summer temperatures on the width of the annual rings, suggesting possible stress caused by higher temperatures during the monsoon season. On the other hand, a positive effect of temperatures on tree growth was observed during late winter months. The response to rainfall was mixed, with a positive effect on growth in November and a negative effect in May and January, suggesting a later onset of the vegetation season. To our knowledge, we present the first dendroclimatological study on this long-lived species in central Bhutan, portraying its potential for future climate and environmental research and applications. |
Insights into panicle trait variation and DUF-640 gene conservation in Indonesian foxtail millets (Setaria italica)Original PaperMarisa Vidya Luthfiani, M. Reza Pahlevi, Bambang Sapta Purwoko, Sintho Wahyuning ArdieCzech J. Genet. Plant Breed., 2025, 61(4):235-246 | DOI: 10.17221/86/2025-CJGPB Foxtail millet (Setaria italica) is a resilient yet underutilised C4 cereal valued for its adaptability to abiotic stress and high nutritional content. While panicle traits have been linked to yield in many cereals, the spatial arrangement of foxtail millet panicles remained unexplored, especially among locally adapted genotypes. This study aimed to characterise spatial panicle architecture traits and to analyse the DUF-640, a gene controlling primary branch number, among Indonesian foxtail millet genotypes. Results revealed substantial variation in panicle architecture, including primary branch number, grain number, and grain density in eight Indonesian foxtail millet genotypes, suggesting potentially greater diversity across broader germplasm. In contrast to the substantial panicle trait variations, phylogenetic and structural analyses showed that DUF-640 genes were highly conserved across Setaria species. Although previously associated with primary branch development, the coding sequence of DUF-640 was not associated with branching variation in this study. However, its high sequence conservation across Setaria species suggests a vital and possibly conserved regulatory function. This study enhances the understanding of the morphological and genetic diversity of foxtail millet, particularly among Indonesian foxtail millet genotypes. Future research should focus on the functional characterisation of DUF-640 and the identification of regulatory sequences governing its gene expression. |
Impact of prebiotic supplementation on the zootechnical and health performance in broiler chickensOriginal PaperM Mansouri, N Hammami, A Yahia, K Saidani, Z Boumahdi, D Tarzaali, N MimouneVet Med - Czech, 2025, 70(12):442-451 | DOI: 10.17221/37/2025-VETMED

Evaluation of Levante × Karakılçık durum wheat advanced lines for yield related and quality traits using principal component biplot analysisOriginal Paperİmren Çöken Tekin, Ali Tekin, Ziya DumlupınarCzech J. Genet. Plant Breed., 2024, 60(3):149-157 | DOI: 10.17221/18/2024-CJGPB The Karakılçık landrace is known for its quality traits, especially protein content. However, its high plant height causes lodging and yield loss, which limits the production area. A Levante × Karakılçık population developed by crossing the local Karakılçık wheat with the commercial variety Levante in order to eliminate the disadvantages of Karakılçık and adapt it to wider production areas. In the study, yield, quality, and some physiological traits were investigated in the population. The experiment was conducted in an augmented experimental design in the cropping seasons of 2021–2022 and 2022–2023. A total of 36 genotypes from Levante × Karakılçık population, parents and 2 controls were tested. The tested genotypes varied significantly for all investigated traits (P < 0.01). Principal component biplot analysis explained 69.3% of the variations and relationships between the traits and genotypes. Among the investigated traits, genotypes LK26, LK19 and LK3 outperformed their parents in 5 traits (spike length (SL), number of spikelets per spike (SNS), number of grain numbers per spike (GNS), protein content (PC) and wet gluten content (G)), 4 traits (SNS, grain weight per spike (GWS), GNS and PC) and 3 traits (grain yield (GY), GNS and test weight (TW)), respectively. The genotype LK3 for yield and the genotypes LK19 and LK26 for quality traits could be recommended to growers and breeders. |
Effect of the combination of nitrapyrin and gamma-aminobutyric acid on soil nitrogen transformation characteristics and rice yieldOriginal PaperFurong Xiao, Chen Feng, Dongpo Li, Lili Zhang, Yonghua Li, Yandi Du, Yan Xue, Ping Gong, Yuchao Song, Ke Zhang, Yiji ZhangPlant Soil Environ., 2024, 70(8):509-522 | DOI: 10.17221/95/2024-PSE When 2-chloro-6-(trichloromethyl) pyridine (nitrapyrin) is applied alone, it typically does not significantly increase crop yield. Therefore, we combined gamma-aminobutyric acid (GABA) with nitrapyrin to address the limitations of nitrapyrin in enhancing yield. We conducted indoor incubation experiments and pot experiments in Chernozem and Calcic Kastanozem, respectively. The results demonstrated that GABA exerted an influence on the effectiveness of nitrapyrin by altering its degradation rate. In Chernozem, GABA accelerated nitrapyrin degradation, whereas, in Calcic Kastanozem, the results were the opposite. The pot experiment results showed that the combination of nitrapyrin and GABA increased rice total biomass by 5%, grain yield by 18 ± 2%, and plant nitrogen (N) uptake by 9 ± 1% compared to nitrapyrin applied alone. The increase in yield was attributed to the combined effect of nitrapyrin and GABA, which elevated root biomass and leaf area. In contrast, the effect of GABA on yield through altering the degradation rate of nitrapyrin was weaker. Therefore, the combination of nitrapyrin and GABA combined with urea increases rice yields in Chernozem and Calcic Kastanozem. The aim of this endeavour was to foster the development of a novel fertiliser product that offers both favourable agronomic outcomes and environmental benefits. |
Influence of the amount of water on the growth of one species and four hybrids of Paulownia in the first year of cultivation in Central EuropeOriginal PaperJiøí Kadlec, Kateøina Novosadová, Martin Kománek, Radek PokornýJ. For. Sci., 2025, 71(6):286-296 | DOI: 10.17221/19/2025-JFS

Eastern Hemlock (Tsuga canadensis) as a new host of Pityokteines spinidens in the arboretum in EuropeShort CommunicationTomá¹ Fiala, Jaroslav Holu¹aPlant Protect. Sci., 2025, 61(3):301-304 | DOI: 10.17221/203/2024-PPS Bark beetle Pityokteines spinidens (Coleoptera: Curculionidae: Scolytinae) is widespread across Europe. We identified this species as a pest of Tsuga canadensis in western Bohemia's Americká zahrada National Nature Monument Arboretum. This discovery suggests that P. spinidens could infest any conifer within the Abietoideae subfamily. Given its status as a known pest of various Abies species, its potential impact on related conifers warrants further attention. |
Wheat (C3) and maize (C4) adaptive responses to soil thallium toxicity under elevated CO2 conditionsOriginal PaperWael A. Obaid, Samy Selim, Seham M. Hamed, Emad A. Alsherif, Shereen Magdy Korany, Hana Sonbol, Danyah A. Aldailami, Soad K. Al JaouniPlant Soil Environ., 2025, 71(8):534-552 | DOI: 10.17221/239/2025-PSE This study investigated how wheat (C3) and maize (C4) respond to soil thallium (Tl) contamination and elevated CO2 (eCO2), aiming to understand strategies for mitigating oxidative stress. Under eCO2, both crops showed higher biomass production. However, high Tl concentration (120 mg/kg) significantly decreased fresh and dry weights by 31–59%, which translated directly to compromised yield. This growth decline is linked to impaired photosynthesis, evidenced by a 54–57% drop in net photosynthetic rate under elevated Tl. Such photosynthetic inhibition intensifies oxidative stress, marked by increased membrane damage and hydrogen peroxide (H2O2). Furthermore, photorespiration contributed to oxidative stress by generating H2O2, with increased activities of glycolate oxidase and hydroxypyruvate reductase rising by 122% and 201%, in wheat and by 179% and 39% in maize, respectively, in response to 120 mg/kg TI under eCO2 conditions. Simultaneously, to mitigate oxidative damage, antioxidant defences were significantly enhanced, resulting in increased activity of the ascorbate (ASC)/glutathione (GSH) cycle, along with elevated levels of metallothionein and phytochelatin for Tl sequestration, as well as augmented glutathione S-transferase activity. Overall, findings reveal complex interactions between CO2 and Tl, highlighting species-specific adaptive responses of C3 and C4 plants. C3 plants use photorespiration to combat oxidative stress, while C3 and C4 plants have strong antioxidant systems to reduce the effects of oxidative stress, promoting crop resilience and growth despite Tl toxicity. |
Mitigating drought effects in maize with Trichoderma harzianum (strain – ESALQ 1306): a bioinoculant for sustainable agricultureOriginal PaperRenato Lustosa Sobrinho, Marcelo Carvalho Minhoto Teixeira Filho, Christiane Abreu de Oliveira-Paiva, Carlos Eduardo da Silva Oliveira, Tiago Zoz, Bruno Rodrigues de Oliveira, Guilherme Carlos Fernandes, Karina da Silva Souza, Afrah E. Mohammed, Modhi O. Alotaibi, Seham. MPlant Soil Environ., 2025, 71(10):735-749 | DOI: 10.17221/330/2025-PSE Agriculture faces increasing challenges due to climate change, underscoring the importance of beneficial microorganisms for enhancing crop resilience and improving soil health. However, the performance of microbial inoculant strains can vary widely depending on the cultivated species and environmental conditions. This study evaluated the ESALQ 1306 strain of Trichoderma harzianum, a soil fungus recognised as a biological control agent for crops such as soybean and strawberry, investigating its potential as a growth promoter in maize (Zea mays L.). Field experiments were conducted with three commercial cultivars (DKB255, DKB360, and 2B810) over two growing seasons, one under irrigation and the other under severe natural drought. The results revealed that Trichoderma (ESALQ 1306) significantly increased plant height, biomass, and grain yield, particularly under drought stress, despite lacking a formal recommendation for maize. The cv. DKB360 showed the greatest response, with yield increases of up to 60% compared to untreated controls. Inoculation also improved nutrient uptake, especially nitrogen, highlighting its potential to maintain soil health and fertility. These findings demonstrate that the ESALQ 1306 strain of Trichoderma is a promising soil bioinoculant for agriculture, capable of improving maize performance under both optimal and stressful conditions. However, it is important to emphasise that genotype-specific responses highlight the need to align bioinoculant application with selecting specific cultivars to ensure inoculation success. This insight is crucial for guiding future breeding programs and establishing clear regulatory guidelines for commercialising biological products, fostering sustainable and resilient agricultural systems. |
Improvement of salt stress tolerance in sugar beet: role of gamma irradiation and cultivar-specific responsesOriginal PaperMaisam Naji, Marjan Diyanat, Davood Habibi, Mehdi Sadeghi Shoa, Weria WisanyPlant Soil Environ., 2025, 71(11):793-804 | DOI: 10.17221/346/2025-PSE This study investigates the effects of salt stress and gamma irradiation on growth, biochemical, and physiological responses in three sugar beet (Beta vulgaris L.) cultivars. Control plants were irrigated with fresh water (EC = 1.1 dS/m), whereas salt stress was imposed with an irrigation of 9 dS/m. Seeds were irradiated with gamma rays (0, 50, 100, 200, 400 Gy) before sowing. Exposure to salt stress reduced root yield (RY), sugar yield (SY), chlorophyll content, and antioxidant enzyme activities (catalase (CAT) and superoxide dismutase (SOD)). In contrast, oxidative damage increased, as indicated by elevated malondialdehyde (MDA) concentrations. Interestingly, salt stress enhanced sugar content, with the Eudoro cultivar showing the greatest resilience, maintaining higher RY and SY and lower MDA compared to the other cultivars. Gamma irradiation at moderate doses (50–200 Gy) alleviated the effects of salt stress, with the strongest improvements in SY observed at 100 and 200 Gy. These treatments enhanced RY, chlorophyll content, and antioxidant activities, while also improving photosynthetic efficiency (Fv/Fm) and cellular integrity. Higher doses (> 200 Gy) reduced sugar content, indicating dose-specific effects. Eudoro exhibited superior salt tolerance, maintaining higher root and sugar yields (RY, SY) and reduced oxidative damage (lower MDA) under salt stress. These findings demonstrate that gamma irradiation at optimal doses enhances salt tolerance in sugar beet, offering cultivar-specific benefits for breeding programmes in saline environments. |
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. |

Effect of surface-applied compost on soil propertiesOriginal PaperMarkéta Miháliková, Kamila Bá»ková, Petr Dvoøák, Recep Serdar Kara, Cansu Almaz, Martin Král, Barbora Badalíková, Kvìtu¹e Hejátková, Vladimír Ma¹án, PatriSoil & Water Res., 2025, 20(2):71-83 | DOI: 10.17221/148/2024-SWR The positive influence of surface compost application without incorporation on soil physical properties is known but remains underexplored. This study evaluated the effects of surface-applied stable and mature compost on basic soil physical and chemical properties, including saturated hydraulic conductivity, aggregate stability, and penetration resistance. Conducted as a semi-operational field experiment in two Czech agricultural sites (A: Blatnice at Jaromìøice and B: Jevíèko; Cambisols with loam and silty clay loam textures, respectively), the plots were treated with compost (SCA) at rates of 4 × 30 t/ha (A) and 1 × 200 t/ha (B) or left untreated as controls (CON). The crops were wheat (A), maize (A, B) and intercrops. Surface compost application began in 2022, and soil sampling and field measurements were conducted during the 2023 and 2024 growing seasons. Results showed significant positive changes (P < 0.05 or lower) in SCA plots compared to CON. Soil organic matter content increased by 27.8% at locality A and by 58.1% at locality B, while saturated water content increased by 5.3% (A) and 11.0% (B) in the latter season. Similarly, pH and electrical conductivity showed increases. Water-stable aggregate ratios increased by 6% to 30% at both localities. Dry bulk density decreased by 10.5% (A) and 15.7% (B). Improvements in saturated hydraulic conductivity (by 28.6%) and penetration resistance were observed only at locality B. These findings show the potential of surface-applied stable and mature compost to enhance soil properties effectively. |
Long-term effects of sugarcane monoculture on soil pedomorphology and physicochemical properties in tropical agroecosystemsOriginal PaperAnna Kusumawati, Amir NoviyantoPlant Soil Environ., 2025, 71(3):213-231 | DOI: 10.17221/648/2024-PSE This study investigates the impact of prolonged sugarcane cultivation on the pedo-morphological characteristics and physicochemical properties of three soil types: Entisols, Inceptisols, and Vertisols, as a basis for determining the improvement step ensuring the sustainability of sugarcane production in Indonesia. Soil samples were collected from fields of sugarcane cultivated for 10, 20, and 30 years to analyse pedo-morphological and physicochemical properties. The results indicate that while Entisols and Inceptisols exhibited significant changes in soil properties with increasing cultivation duration, the pedo-morphology of Vertisols remained relatively stable. All soil types developed Ap horizons due to sugarcane cultivation, with anthropogenic practices leading to more dynamic changes in surface horizons. Extended cultivation reduced soil organic matter, N-total, and available nitrogen, while phosphorus and exchangeable cation availability were influenced by mineral composition. Notably, cation exchange capacity (CEC) decreased in Entisols and Inceptisols but increased in Vertisols. For productivity, Vertisols demonstrated the most stable and highest sugarcane productivity with long-term monoculture cultivation. There is a need for tailored sustainable soil management across different soil types and practices to mitigate soil degradation and maintain nutrient availability to ensure the sustainability of sugarcane production in Indonesia. |
Determination of resistance improving potentials of cotton whitefly Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) biotypes against cyantraniliproleOriginal PaperIsse Hassan Ali, Utku YükselbabaPlant Protect. Sci., 2025, 61(2):191-200 | DOI: 10.17221/112/2023-PPS Bemisia tabaci is a significant insect pest that causes extensive agricultural damage. The MEAM1 (Middle East-Asia Minor) and MED (Mediterranean) genetic groups of B. tabaci are the most prevalent cryptic species. This study investigated the potential for resistance development in the MED and MEAM1 genetic groups of B. tabaci against cyantraniliprole. Additionally, multiple-resistance development within each genetic group for pyriproxyfen, spirotetramat, and acetamiprid insecticides was determined. To assess the susceptibility of the first-larval stage of B. tabaci, we employed a systemic uptake method with cyantraniliprole. Additionally, we utilized a leaf-dipping method to apply acetamiprid, spirotetramat, and pyriproxyfen to second-instar larvae, adults, and eggs of B. tabaci, respectively, to determine the LC50 values for each insecticide. Each genetic group was subjected to six selections using cyantraniliprole. After six rounds of selection, a 1.8-fold resistance was observed in the B. tabaci MEAM1 population, whereas the MED population exhibited a 1.4-fold resistance. While B. tabaci MED and MEAM1 genetic groups exhibited very low resistance to cyantraniliprole, it's important to note that no multiple-resistance was observed with pyriproxyfen, spirotetramat, or acetamiprid in either group. These findings provide valuable insights for future monitoring and developing insecticide resistance management strategies for B. tabaci. |
Influence of 'Candidatus Phytoplasma prunorum' on primary and secondary metabolites of apricotsOriginal PaperGabriela Trempetiæ, Eli¹ka Zezulová, Tomá¹ Neèas, Petr ©nurkoviè, Tomá¹ KissPlant Protect. Sci., 2025, 61(3):242-254 | DOI: 10.17221/128/2024-PPS 'Candidatus Phytoplasma prunorum' ('Ca. P. prunorum') is a causative agent of European stone fruit yellows (ESFY), an economically important decline disease of some stone fruit species (Prunus spp.). The present research focused on the influence of 'Ca. P. prunorum' on primary and secondary metabolites in four apricot genotypes consisting of older trees (genotypes Nora, LEM 159, group 1) and younger trees (genotypes H 74 and H 177, group 2). The content of sugars (glucose, sucrose, fructose and sorbitol), total phenolic content (TPC), total flavonoid content (TFC), antioxidant capacity (AC), total soluble proteins (TSPC), mineral ions: potassium (K+), sodium (Na+), magnesium (Mg2+) and calcium (Ca2+), pigments: chlorophyll a, b and carotenoids, and indolic compounds content (ICC) were analysed in two time periods during the year in the leaves of tested trees. The results revealed that the presence of phytoplasma/ESFY symptoms significantly decreased the content of pigments in both groups during the summer sampling period. ESFY caused a decrease of TPC, TFC and ICC in the H 177 genotype. The phytoplasma decreased the TSPC and K+ content in older trees during both sampling periods. The only increase caused by phytoplasma infection was observed in glucose content, but only in the group of older plants. The results of this study support the idea that 'Ca. P. prunorum' affects metabolites in plants' defence system and manipulates basic metabolic processes during successful infection. |
Immobilised Aspergillus niger lipase synthesises sn-1,3-dioleoyl-2-palmitoylglycerolOriginal PaperShanhui Chen, Renbin Liu, Dong Wang, Shiyou Li, Zhirong YangCzech J. Food Sci., 2025, 43(4):291-299 | DOI: 10.17221/143/2024-CJFS sn-1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a structural triglyceride with a specific distribution of fatty acids, which is an important component of breast milk fat and which can better promote the absorption of minerals and energy in infants. In this study, a lab-made immobilised Aspergillus niger lipase (IM-ANL), which is more economical than a commercial lipase, was used for hydrolysis to produce free fatty acids (FFA) and acidolysis interesterification to produce OPO. The enzyme was used for multiple purposes, reducing the cost of enzymatic production. The optimum conditions for hydrolysis were determined by experiments: the amount of IM-ANL enzyme dosage was 3%, the reaction temperature was 45 °C, and the reaction time was 48 h. The optimum conditions for acidolysis interesterification were as follows: the amount of IM-ANL enzyme dosage was 4%, the molar ratio of tripalmitin to oleic acid was 1 : 8, the reaction temperature was 55 °C, and the reaction time was 3 h. In this study, economical palm stearin and high oleic acid sunflower seed oil were selected as reaction raw materials, and the reaction temperature was moderate, the safety risk was low, the energy consumption was reduced, the process was more economical, and the economic value of high oleic acid vegetable oil was improved, which was conducive to the further promotion of OPO production. |
