Rainfall variability in the mountain forest catchments of Èerná Opava tributaries in the Jeseníky MountainsOriginal PaperVít ©rámek, Vìra Fadrhonsová, Kateøina Neudertová HellebrandováJ. For. Sci., 2025, 71(3):138-148 | DOI: 10.17221/96/2024-JFS An unprecedented bark beetle outbreak has led to a significant decline in forest cover in Central Europe in the last 10 years, affecting an area estimated at more than 200 000 ha in the Czech Republic. Among the many ecological threats associated with extensive clearings, the potential alteration of hydrological processes is one of the most important. Therefore, after 2022, the precipitation–runoff balance in three catchments in the Jeseníky Mts. area was studied. This study focuses on the rainfall variability within the area, which was measured using 24 rain gauges deployed to cover different altitudes as well as the geographical exposures of the mountain catchments. Precipitation data was evaluated based on seven-day totals within the frost-free period. There was a significant increase in precipitation with altitude (12% increase for every 100 m a.s.l.) but only in less than half (48.7%) of the evaluated periods. No significant trend was demonstrated in the remaining periods, and a negative trend in precipitation with altitude was identified in 8.9% of cases. Additionally, the role of exposure was insignificant, although a tendency towards slightly lower precipitation was found for the eastern exposure at altitudes up to 1 000 m a.s.l., which may be related to the prevailing wind direction. We concluded that even a relatively dense monitoring network is not necessarily sufficient to provide accurate precipitation data in forested catchments, especially in mountain areas. Under such conditions, the use of complex models that also use radar data is recommended. |
How economic policy uncertainty affect the scale-up of hog breeding in China?Original PaperChunlei Li, Tao Feng, Gangyi Wang, Amètépé Nathanaël Beauclair AnaniAgric. Econ. - Czech, 2025, 71(4):203-217 | DOI: 10.17221/8/2024-AGRICECON In recent years, China has promoted large-scale hog farming through various approaches. However, this scale-up process may be affected by economic policy uncertainty. This paper empirically examines the impact of policy uncertainty on hog farming scale-up using provincial panel data from 2016–2022 and a fixed-effects model. Our results indicate that economic policy uncertainty significantly inhibits hog farming scale-up, and this effect remains significant even when we increase the criteria for recognising scale-up, alternative estimation methods include two-stage least squares (2SLS), dynamic panel model and panel Poisson model. Mechanism analysis reveals that economic policy uncertainty not only exacerbates the impact of labour and capital factor prices on scale-up hog farming but also exacerbates the volatility of hog prices, which further raises the risks faced by hog farming and inhibits scale-up hog farming. Heterogeneity analysis reveals that the effect of economic policy uncertainty on hog farming scale-up decreases as farm size increases. Higher-level economic policy uncertainty can inhibit scale-up hog farming, while lower-level economic policy uncertainty can instead promote scale-up hog farming. Economic policy uncertainty has a more obvious inhibitory effect on scale-up hog farming in major development areas. These findings have important implications for the promotion of large-scale hog farming and related policy regulation. |
Allogeneic adipose MSCs and autologous PRP for chronic non-healing wound in a catCase ReportN Suwan, S Jenjittikul, R Tiratrakoonseree, C Jiradanaipat, S Teerawongsuwan, Wi Phathomrapeepong, W Phanwanich, R RungsiwiwutVet Med - Czech, 2025, 70(4):143-149 | DOI: 10.17221/93/2024-VETMED Management of chronic non-healing wounds in cats requires a comprehensive approach. This report describes the treatment of a severe open skin wound on the skull using a combined approach involving allogeneic adipose-derived mesenchymal stem cells (MSCs) and autologous platelet-rich plasma (PRP). A 12-year-old neutered male mixed-breed domestic cat presented with a non-healing chronic wound on the skull. The wound extended from the orbital to the occipital area and from the left to the right temporal region. Laboratory test results were positive for feline immunodeficiency virus and impaired kidney function. Sensitivity tests revealed resistance to several antibiotics. Due to limited skin reconstruction options, MSCs were administered subcutaneously at the wound edge once a month for three months. PRP was collected one month after the initial MSC administration and injected at the wound edge monthly between MSC treatments. The wound diameter was measured daily during saline cleaning. The cat received protein-supplemented food daily. Wound healing was observed two weeks after the MSC administration, gradually decreasing in size and closing completely within 5 months. This case demonstrates the successful application of MSCs and PRP for treating chronic wounds in cats. |
Uveodermatological syndrome in dogs: A review of diagnosis, management, and ophthalmic patient needsReviewP Zubricky, A Balicka, Z Drahovska, M Lapsanska, A TrbolovaVet Med - Czech, 2025, 70(6):185-195 | DOI: 10.17221/10/2025-VETMED Uveodermatological syndrome is a widely recognised disease that continues to raise significant concern among both veterinarians and pet owners. Its aetiology, although still unclear, is believed to involve an autoimmune origin and genetic predisposition. The most common clinical signs include skin depigmentation, alopecia, poliosis, and, most frequently, granulomatous panuveitis. Affected dogs often develop secondary complications owing to persistent intraocular inflammation, such as cataracts and glaucoma. Although immunosuppressive therapy often yields a favourable response, recurrence is commonly observed. In some cases, uveodermatological syndrome presents a clinical challenge, as patients may experience adverse effects from medications, without which irreversible blindness may ensue. |
Innovative use of mine tailings as a soil amendment for growing Pisum sativum L.Original PaperMohammed Kharbouche, Khalid El Khalidi, Redouane Mghaiouini, Ahmed Aajjane, Bendahhou ZourarahPlant Soil Environ., 2025, 71(7):487-499 | DOI: 10.17221/91/2025-PSE This study investigates the benefits of using mine tailings (MT) to improve pea (Pisum sativum L.) growth and productivity on degraded agricultural soils in semi-arid environments. The research aims to evaluate the use of MT as an innovative soil amendment and to determine the optimal dose required to enhance the micronutrient availability of Zn, Mn, Cu and Fe without affecting soil quality. The experiment was conducted in greenhouse pots with three different soil types amended with different MT doses (control and four doses). Soil samples were collected from the Doukkala region, one of the main agricultural areas in Morocco. Pea was grown in pots and monitored for 87 days until maturity. After harvest, soil and plant samples were weighed, measured and analysed by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The experiment found that moderate doses (0.2 g/kg to 1 g/kg) applied to all soil types promoted optimal pea growth by improving plant height, root and above-ground biomass and pod number. Thus, MT can act as a biostimulant. However, nutrient antagonism negatively affected growth at the highest dose (4 g/kg). Bioconcentration and translocation factors indicated efficient micronutrient uptake and biofortification, while heavy metals remained immobilised in roots, effectively eliminating toxicity risks. |
Does livestock manure recycling among acquaintance networks decouple crop and livestock production? Evidence from rural ChinaOriginal PaperYing Wang, Guanghui Jiang, Jisheng MinAgric. Econ. - Czech, 2025, 71(9):512-525 | DOI: 10.17221/219/2024-AGRICECON Livestock manure serves as a vital source of organic fertiliser, with efficient utilisation being crucial for sustainable agricultural development. However, with the development of specialised high-input agriculture, livestock manure recycling (LMR) is currently inefficient and leading to the imbalance between surplus manure and croplands. This study theoretically and empirically investigates whether LMR among acquaintance networks influence the crop–livestock integration (CLI) production. Based on survey data of swine farmers in rural China, the estimates indicate that LMR among acquaintance networks enhances the degree of CLI but may result in over-application of manure. Conversely, LMR with outside villagers or organisations is more likely to reduce the degree of CLI, possibly leading to under-application of manure. The motivation behind farmers' LMR plays a crucial role. Furthermore, the study indicates that formal institution can break the constraints of acquaintance networks on LMR and restructure the crop-livestock relationship beyond the household level. Our findings emphasise that LMR within rural China's acquaintance networks are in a transition phase, exhibiting both relational and market orientation characteristics. It is currently essential to maintain the balance between crop and livestock production, advance the development of LMR social services when designing LMR policies, and to leverage the complementary roles of informal and formal institutions. |
Effect of dietary hop extracts and humic substances on the growth performance, carcass yield, blood biochemistry parameters, and meat quality of rabbitsOriginal PaperZuzana Lacková, Franti¹ek Zigo, Zuzana Farka¹ová, Jakub Je¹ík, Jana Záhumenská, Silvia Ondra¹ovièová, Andrej Récky, Henrieta Arpá¹ováCzech J.

Can agricultural subsidy reform promote reduction of fertiliser nonpoint source pollution? Evidence from ChinaOriginal PaperFusheng Liang, Guangsi Li, Wo-lin Zheng, Fangyuan Sun, Qian YangAgric. Econ. - Czech, 2025, 71(9):485-501 | DOI: 10.17221/412/2024-AGRICECON The substantial increase in grain production stimulated by traditional agricultural direct subsidies has been accompanied by a concomitant decrease in ecological quality, precipitated by excessive application of chemical fertilisers, which has generated countervailing effects that fundamentally undermine the positive effect of subsidy policies on agricultural output. Consequently, the mitigation of agricultural pollution and the elevation of ecological quality have emerged as pivotal directions for the reform of agricultural subsidies. Using both time-varying difference-in-differences (DID) models and spatial DID models in this study, we examined the effect of agricultural 'three subsidies' reform on agricultural fertiliser nonpoint source pollution (AFNSP), drawing on China's province-sector panel data from 2008 to 2022. The empirical evidence yields several salient findings. First, the three subsidies reform can significantly reduce AFNSP and improve ecological quality. Second, the large-scale operation of agricultural households and the enhancement of agricultural production efficiency serve as effective pathways for the three subsidies reform to reduce AFNSP. Third, the implementation of the three subsidies reform engenders significant spatial spillover effects, which play a crucial role in reducing overall regional AFNSP. Fourth, the efficacy of the three subsidies reform exhibits heterogeneity across diverse agroecological contexts and farming cultures. Last, the reform has resulted in notable improvements in agricultural ecological quality, thereby reinforcing food security capabilities. These findings not only offer valuable reference for refining agricultural subsidy reform but also contribute to the development of a comprehensive framework that simultaneously safeguards agroecological security and food security. |
The use of LiDAR for the documentation and modelling of cultural heritage sites hidden by the forest canopyOriginal PaperNikola ®i¾lavská, Stanislav HerberJ. For. Sci., 2025, 71(10):501-515 | DOI: 10.17221/53/2025-JFS The large number of charcoal kiln sites (CHKS) preserved as cultural heritage monuments demonstrates how extensive forest management for charcoal production has influenced the present forest dynamics and contributed to industrial expansion. Therefore, it is necessary not only to have a reliable methodology for detecting and documenting individual kiln sites for management and protection purposes but also to present the results in a meaningful way to the public. The aim is to optimise the data processing workflow from airborne laser scanning (ALS) point cloud to printable model (from LAS format to STL), determine the influence of vegetation cover at the time of data collection on the quality of the resulting model, verify the quality of printed models using photogrammetry, and finally, produce printed models of CHKS as cultural heritage objects in a form that can be effectively presented to the public. After comparison of different ground filtering methods, we conclude that the most accurate method for creating a precise ground representation for our area of interest was the Cloth Simulation Filtering (CSF) algorithm. From the filtered point cloud, a high-resolution raster surface was generated, which served as the basis for CHKS detection. Using our proposed methodology – combining the topographic position index (TPI) with a 0–5% slope threshold – we achieved a significant improvement in detection performance compared to using a zero-slope threshold alone, with the F1 score increasing from 0.667 to 1.000. Subsequently, the most representative kiln site was selected, which was then processed and optimised using various software tools, resulting in an exchangeable STL file suitable for dissemination and 3D printing. The accuracy of the printable model was then evaluated. We conclude that point cloud from the winter flight campaign achieved higher accuracy. The average height differences were similar; however, the spatial distribution varied between the two clouds. The model from the winter flight campaign had more evenly distributed deviations and overall was better for modelling the CHKS. |
Expression and analysis of StNR and StNiRs, key enzyme genes of nitrogen assimilation in potato (Solanum tuberosum L.) with different nitrogen efficienciesOriginal PaperYuzhu Han, Zhijun Han, Yue Lu, Zhongcai Han, Jiayue Zhang, Jingying Zhang, Hongyu Qiao, Hongxia HeCzech J. Genet. Plant Breed., 2025, 61(4):193-209 | DOI: 10.17221/22/2025-CJGPB The potato is a pivotal food crop on a global scale. Nitrate reductase (NR) and nitrite reductase (NiR) are the key enzymes in nitrogen assimilation. In previous research, we found that the nitrogen assimilation process was effectively regulated by StNR and StNiRs in potato and that there were significant differences in nitrogen utilisation efficiency between different potato varieties. In this study, three potato variants with different nitrogen use efficiency (NUE) were subjected to various nitrogen supply levels and photoperiod treatments. The results indicated that the relative expression levels of StNR and StNiRs in their leaves and roots, along with the enzyme activity of NR and NiR, were proportional to the nitrogen supply levels and photoperiod. This study further clarified the expression patterns of StNR and StNiRs, as well as the enzyme activity changes of NR and NiR in leaves and roots under different nitrogen supply levels and different photoperiod treatments. This provides a theoretical basis for further in-depth exploration of the specific functions related to nitrogen absorption and assimilation efficiency in potato. |

Evaluating the indicators of a heart rate variability analysis in dogs using Poincaré plotsOriginal PaperT Kimura, S Shimamura, H Sakaya, T Hayashi, A Umemoto, K Sakai, M Yamasaki, T Hasegawa, T ShimadaVet Med - Czech, 2024, 69(2):42-51 | DOI: 10.17221/49/2023-VETMED Heart rate variability analyses using Poincaré plots can be useful for evaluating the autonomic nervous system function. However, the interpretation of the quantitative indicators of Poincaré plots remains controversial. Thus, few studies have verified the effectiveness of the quantitative indicators in veterinary medicine. This study aimed to verify the reliability of Poincaré plot indicators using pharmacological models in dogs. Four healthy beagles were used in this study. Each dog was treated with propranolol, atropine, and propranolol–atropine to block the sympathetic, parasympathetic, and sympathetic–parasympathetic functions, respectively. The quantitative indicators of the Poincaré plots were calculated based on data from 300 electrocardiogram beats collected before and after the administration of each drug and statistically analysed. The quantitative indicators of the Poincaré plots, such as the standard deviation perpendicular to the major axis (SD1), standard deviation along the major axis (SD2), and SD1 × SD2, significantly decreased after the drug administration in both the parasympathetic and sympathetic–parasympathetic blockade models. However, no significant differences were observed in SD1/SD2 between the groups. The Poincaré plots reflected the changes in the autonomic nervous system of dogs. In dogs, SD1, SD2, and SD1 × SD2 can detect a state in which parasympathetic nerve activity is suppressed. |
The nurse sow system ‒ A natural process of handling large litters: A reviewReviewJoab Malanda Osotsi, Gabriella Novotni-Danko, Peter BaloghCzech J. Anim. Sci., 2024, 69(3):89-101 | DOI: 10.17221/158/2023-CJAS Reproductive performance in pig production has gained genetic momentum resulting in large litters. Several strategies have been used to raise the number of piglets to address the challenge of a large litter size. This review provides a rationale for employing the nurse sow system as a biological way of handling large litters, exploring its step-by-step processes and its selected impacts. By exposing these steps, pig farmers will use the information to pinpoint their weak points in the chain and customize the procedures to meet their farm-specific goals for improved productivity. The nurse sow system helps to maximize pre-weaning survival by boosting the overall worth of low birth weight piglets. When piglets weaned per sow/year are used as a performance benchmark, nurse sows weaning double litters become economically advantageous. Extended time in lactation for nurse sows gives them an ample time for their uterus to involute before the next pregnancy. However, nurse sows lose their body reserves reflected in backfat thickness from high milk production. Prolonged confinement in lactation deteriorates the physical condition of nurse sows, resulting in leg ulcers and teat damage. Additionally, piglets are more distressed when taken away from their biological sow to a new sow. |
Exploring the weed host range of resistance-breaking variants of tomato spotted wilt orthotospovirus (TSWV) across life cycles in TürkiyeOriginal PaperHakan Fidan, Ailar Gonbad, Yasin Emre KitisPlant Protect. Sci., 2024, 60(2):127-138 | DOI: 10.17221/118/2023-PPS Tomato spotted wilt orthotospovirus (TSWV) is destroying tomato and pepper resistance all over the world, including Antalya (Türkiye). Two greenhouses that show infection of TSWV in the Serik (coastal) and Elmali (highland) areas were chosen for research between 2019 and 2021 to better understand the disease's life cycle. During the surveys, we focused on weed hosts to better understand TSWV disease's cycle. TSWV infection was determined in 58 peppers, 34 tomatoes, 270 weeds, and 20 other vegetable samples. Weed samples revealed essentially no symptoms, however, grown plants showed classic TSWV symptoms. The Asteraceae family had the highest infection rate among infected weeds, followed by weed species from the Poaceae and Solanaceae families. In addition, to determine the viral strain in the infected plant samples, qRT-PCR and Melt-curve analysis were done using a specially designed primer pair for the study. This primer identifies the point mutation on the NSm-movement protein in the viral genome's medium segment. The non-resistance breaking isolate of TSWV was included in the optimisation studies to evaluate differences between the two isolates at two thermal melting values established by this comparison. These findings demonstrated that the kits, procedures, and primers employed in this investigation can serve as a quick and reliable diagnostic tool for identifying TSWV isolates and that weeds are a key intermediate source for new TSWV infection, as confirmed by sequence data. |
The control of soil-borne fungal pathogens in grapevine nurseries in Türkiye and their impact on sapling qualityOriginal PaperNurdan Gungor SavasPlant Protect. Sci., 2024, 60(3):241-257 | DOI: 10.17221/94/2023-PPS In the production of grafted vines, losses are caused by fungal pathogens during callus forming or after planting in the soil. To control or reduce natural soil-born fungal infections in nurseries, certain applications were conducted in the sapling cultivation stage to analyse the efficacy of cyprodinil + fludioxonil, fluopyram + tebuconazole active substances, and Trichoderma harzianum biological preparation: 1103 Paulsen rootstock and Vitis viniferea L. cv. In the study, Sultana cultivars were stored in fungicide suspensions for 60 min before and after grafting. After grafting, the saplings were divided into (i) cutting + sawdust (ii) cutting + sawdust + soil application groups and transferred to the callus room. After nine months in the nursery, the plants were uprooted, classified as diseased or healthy, and analysed for morphological and molecular diagnosis of fungal species, isolation incidence, and sapling quality and yield. Boeremia exigua var. exigua was isolated for the first time from cuttings during grapevine sapling production and was first registered in NCBI Genbank. After callus development, Fusarium solani was most frequently isolated pathogen in the roots (21.5%); cyprodinil + fludioxonil reduced the Ilyonectria sp. isolation rate in both shoots and roots. Botryosphaeria dothidae and I. liriodendri pathogens were not detected in disease and healthy cyprodinil + fludioxonil treated saplings. The highest sapling yield was observed in fludioxonil + cyprodinil, cutting + sawdust + soil (78.75%) and cutting + sawdust (70.63%) applications. |
Quo vadis, breeding for an efficient root system, in the era of climate change?ReviewTomá¹ Støeda, Jana Hajzlerová, Jhonny Alba-Mejía, Ivana Jovanoviæ, Nicole Frantová, Hana StøedováCzech J. Genet. Plant Breed., 2024, 60(4):181-211 | DOI: 10.17221/57/2024-CJGPB Despite all the complications that arise with root research, such as slow, laborious, and unclear genetics, roots are a promising object of interest for breeders because many root traits are compatible with high yield potential. It is a great challenge for further research that there is a wide demand for information on the “hidden half of plant metabolism” from many research fields. We have summarized the main obstacles in root system research and sketched a solution for breeding in field conditions so that the result was more meaningful to the farmer. (i) The most important challenge in root research is linking the functional identification of root system properties with the aboveground parts. (ii) Field breeding is irreplaceable, and methods allowing the evaluation of roots under field conditions are indispensable. (iii) Low heritability of root system trait discourages breeders. However, root properties show broad genotypic variability, allowing the efficient use of these traits as selection criteria. (iv) The root traits are variable, and many fluctuate under the influence of environmental factors, which complicates efforts to define ideotypes and explains the different conclusions obtained by researchers from different environments. The breeding programs targeting the root system are sporadic even in a global context. This is a great reserve for breeding progress in the era of climate change, water scarcity, a possible shift to extensive farming systems, and in the era of environmental programs. |

Detection of genomic loci associated with days to heading in tropical japonica rice through QTL-seqOriginal PaperKhairul Yusuf Nasution, Dani Satyawan, Muhamad Yunus, Azri Kusuma Dewi, Puput Melati, Marina Yuniawati Maryono, Ita Dwimahyani, Wening Enggarini, SobrizalCzech J. Genet. Plant Breed., 2025, 61(1):23-30 | DOI: 10.17221/66/2024-CJGPB This study investigated the genetic basis of days to heading (DTH) in tropical japonica rice using F2 populations derived from late-maturing Rojolele and early-maturing Rojolele Srinuk varieties. Phenotypic analysis of DTH showed continuous distribution and positive skewness. Whole genome sequencing (WGS) derived single nucleotide polymorphism (SNP) from early and late-heading bulks were used to identify three candidate regions with strong association to DTH: qDTH3.1 and qDTH3.2 on chromosome 3, and qDTH7.1 on chromosome 7, with the latter linked to the Oryza sativa Pseudo-Response Regulator 37 (OsPRR37) gene. InDel markers validated qDTH7.1’s significant linkage to DTH, particularly marker ID14, which is effective for marker-assisted selection of early DTH in Rojolele background. |
Assessment of ozone impact on forest vegetation using visible foliar injury, AOT40F exposure index and MDA concentration in two meteorologically contrasting yearsOriginal PaperRadek Novotný, Leona Vlasáková, Vít ©rámek, Václav Buriánek, Nina Bene¹ováJ. For. Sci., 2025, 71(1):40-56 | DOI: 10.17221/57/2024-JFS This study aimed to evaluate ozone (O3) phytotoxic potential using AOT40F (accumulated O3 concentration over a threshold of 40 ppb for forest protection), document visible foliar O3 injury across eight forest monitoring plots, analyse MDA (malondialdehyde) content in leaves and needles, and assess the relationship between visible injury and plot conditions. Initial findings are based on data from the 2021 and 2022 vegetation seasons. AOT40F values exceeded the critical level of 5 ppm·h–1 at all plots, with higher values in 2022. The correlation between AOT40F and visible injury was inconsistent; in 2021, minimal visible O3 injuries were observed, while these were more frequent in 2022, notably on Fagus sylvatica leaves. The altitude effect on O3 concentration indicates greater vegetation damage at higher altitudes. In contrast, the AOT40F-altitude relation was not significant. The 2021 vegetation season was characterised by lower temperatures and higher relative air humidity and soil moisture in comparison to 2022. Stomatal conductance conditions were similar in both years, except for lower soil moisture in 2022. Soil moisture, air humidity, and temperature together accounted for about 50% of the variance in visible injury in 2022. The findings suggest that the AOT40F capability for predicting damage to vegetation is limited and highlight the importance of future research focusing on stomatal O3 flux-based approaches. |
Effectiveness of glycerin-oxalic acid strips and essential oils in controlling Varroa destructor in honeybeeOriginal PaperPR Hristov, IS Hristakov, AZ Atanasov, PA ZhelyazkovVet Med - Czech, 2025, 70(3):101-109 | DOI: 10.17221/94/2024-VETMED The decline in the bee colony strength due to high levels of Varroa destructor infestations necessitates the development of new control methods. This study evaluates the effectiveness of glycerin-oxalic acid strips and essential oils in managing Varroa destructor. The experiment was conducted in 2022 at the experimental apiary in Debelec, part of the Institute of Animal Husbandry in Kostinbrod. Six experimental groups, each treated with a different preparation, were compared to a control group of untreated colonies. Treatments included Beevital Hiveclean (20 ml per colony), Varro Red (2 ml per frame), ammonium nitrate strips (1.3 mm), glycerin-oxalic acid strips (1.3 mm), and glycerin-oxalic acid strips of paper-cellulose (2.3 mm) or cellulose-cotton (2.3 mm). The control group remained untreated. The glycerin-oxalic acid strips made of cellulose and cotton (2.3 mm) showed the highest efficacy, reducing the mite infestation by 17.79% compared to the control. The glycerin-oxalic acid strips of paper-cellulose (2.3 mm) were also effective, achieving a 17.05% reduction in mite levels. These results provide valuable insights for beekeepers seeking alternative and sustainable methods for controlling Varroa destructor infestations. |
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. |
Assessing the accuracy of a root detector in mapping radial tree root distributionOriginal PaperMochammad Taufiqurrachman, Utami Dyah Syafitri, Goh Mia Chun, Lina KarlinasariJ. For. Sci., 2025, 71(8):406-415 | DOI: 10.17221/27/2025-JFS A root detector is a non-destructive technology developed to indicate the radial distribution of tree roots, which are not often visible on the surface. This study aims to assess the accuracy of the root detector in estimating the radial distribution of both exposed and buried tree roots. Six Agathis loranthifolia Salisb. trees were selected, three with exposed roots and three with buried roots. The Fakopp® root detector, an acoustic-based tool, was used in this study. Root estimation was based on a combination of threshold values (> 400 m·s–1), average values, and the peak of the sound wave velocity. Soil excavation was manually conducted at a depth of 30 cm within a 100 cm radius of the tree trunk. The results showed that under similar soil conditions, the root detector achieved an accuracy of over 80% in detecting the actual radial root distribution, as validated by the excavation method. Root diameter exhibited the strongest correlation with sound velocity in detecting lateral roots. However, root depth and inclination angle contributed to detection inaccuracies in estimating the radial distribution of lateral roots. |

Revitalising subalpine grasslands: floristic shifts under renewed grazingOriginal PaperMarie Mrázková-©týbnarová, Michaela Koláøová, Radek ©tencl, Prokop ©mirous, Marie Bjelková, Josef Holec, Martin Va¹inka, Ludìk Ty¹er, Oldøich LátalPlant Soil Environ., 2025, 71(5):338-352 | DOI: 10.17221/12/2025-PSE The species diversity of the unique flora in the Hrubý Jeseník Mountains is currently threatened due to the absence of traditional grazing, which was historically used as a management practice. This study evaluates changes in floristic composition in areas near the ©výcárna and Ovèárna lodges, where cattle and sheep grazing was reintroduced in 2012 and 2014, respectively, after long-term abandonment. The floristic composition was assessed using permanent plots and analysed statistically. In total, 84 plant species were recorded in the ©výcárna experimental area over 12 years. All experimental plots throughout the study observed an increase in species richness. In the Ovèárna area, a similar trend was detected, particularly in grazed grasslands dominated by Avenella flexuosa, Festuca supina, and Ligusticum mutellina. The reintroduction of grazing in these areas serves not only as a symbolic return to traditional land use but primarily as an effective management tool to suppress ecological succession and maintain or enhance plant species diversity in biologically valuable habitats. |
Stability of soil moisture sensors for agricultural crop cultivationShort CommunicationSitti Nur Faridah, Muhammad Tahir Sapsal, Tisha Aditya A. Jamaluddin, Andini Dani Achmad, Muhammad Adi SuryaRes. Agr. Eng., 2025, 71(2):88-94 | DOI: 10.17221/33/2024-RAE Soil water content is critical in plants’ morphological and physiological processes; therefore, water must always be available in appropriate quantities to meet plant growth needs. Soil moisture can be easily detected using sensors, which offer a practical solution for monitoring water content in the soil. However, using sensors for a long time, especially on agricultural land, will reduce sensor accuracy. This research aims to investigate the accuracy of soil moisture sensors during their use for cultivating crops. Using sensors in sandy clay soil can detect soil moisture levels with an accuracy of 93.80% and a precision of 90.81%. A reading deviation (error) of up to 49.74% with a precision level of 75.69% occurred when the sensor had been used for 40 days. Regular cleaning and calibration of the sensor are necessary to obtain accurate soil moisture readings. A copper-based sensor module kit can be used to detect soil moisture with reasonable accuracy during plant growth with a 5–6 weeks harvest time. |
Decontamination of Aspergillus parasiticus in rice by dielectric barrier discharge cold plasma: Variable effects and mechanism of degradationOriginal PaperZhu Shuo, Yan Zhongjun, Shanshan Shi, Ai Zhi, Chenghong Wang, Fei ShenCzech J. Food Sci., 2025, 43(3):226-234 | DOI: 10.17221/153/2024-CJFS Rice is prone to be contaminated with spoilage or toxigenic fungi during harvest, storage and processing, with Aspergillus species being the most frequent. It is crucial to develop effective sterilisation technologies for mycotoxin prevention and food safety. In this study, sterilised rice infected by Aspergillus parasiticus strain was treated by dielectric barrier discharge (DBD) cold plasma. Various parameters, including moisture content, oxygen content, treatment time and voltage were tested. Furthermore, sterilisation mechanism of Aspergillus parasiticus by cold plasma was also explored. Results indicated that decontamination effect could be significantly affected by moisture content, oxygen concentration, voltage and treatment time. A 99.89% degradation rate against Aspergillus parasiticus was achieved at 90 kV after 5 min. Cold plasma could reduce the initial concentration of 6.05 to 2.28 CFU·mL–1 within 240 s, and to thoroughly decontamination within 360 s. In addition, cold plasma treatment destroyed the integrity of Aspergillus parasiticus cell membrane, resulting in a reduction in mycelium biomass and dry weight, as well as a significant decrease in intracellular Ca2+Mg2+-adenosine triphosphatase (ATPase) activity. These findings demonstrate the potential of cold plasma technology for environmentally friendly sterilisation of hazardous fungi in grain system. |
Evidence and characterisation of Xanthomonas arboricola pv. juglandis causing bacterial blight of walnut in MontenegroOriginal PaperJelena Latinoviæ, Nedeljko Latinoviæ, Bogoljub Kandiæ, Aleksandra Jelu¹iæ, Tatjana Popoviæ MilovanoviæPlant Protect. Sci., 2025, 61(3):255-261 | DOI: 10.17221/196/2024-PPS This study represents the first evidence of the bacterial blight caused by Xanthomonas arboricola pv. juglandis (Xaj) on walnut trees in Podgorica (Montenegro). Disease symptoms appeared on leaves in the form of dark, angular leaf spots surrounded by yellow-green haloes and lesions spread across the whole leaf. Isolated bacteria were preliminarily identified using PCR with pathovar-specific primer pair XajF/XajR and further characterised based on multi-locus sequence analysis with nine housekeeping genes (fusA, gapA, gltA, gyrB1, lepA, rpoD, dnaK, fyuA, and gyrB2). Montenegrin walnut isolates were homogeneous among themselves and the most closely related to different X. arboricola strains originating from Juglans regia isolated elsewhere. The pathogenicity of isolates was confirmed on walnut leaves, fruits, and branches. All inoculations resulted in the formation of necrotic lesions that initially developed at the site of bacteria entry, with later developing chlorotic areas on leaves along the leaf veins. This finding of Xaj causing leaf blight symptoms on walnuts in Montenegro highlights its expanding distribution across Europe and indicates a potential threat to walnut plantations in Montenegro. |
The use of parenteral application of ferric carboxymaltose in the prevention of iron deficiency anaemia in suckling pigletsOriginal PaperM Svoboda, J Vasek, J Jarkovsky, V Skupien, V VitkovaVet Med - Czech, 2025, 70(7):242-246 | DOI: 10.17221/22/2025-VETMED This study aimed to evaluate the effectiveness of ferric carboxymaltose injection in the prevention of anaemia in suckling piglets. In group A (n = 8), piglets were administered iron in the form of iron carboxymaltose complex (Ferinject®) at a dose of 200 mg i.m. (neck muscle) at the age of 3 days. In group B (n = 8), piglets were given iron in the form of iron dextran (Ferribion®) at a dose of 200 mg i.m. (neck muscle) at the age of 3 days. In group C (n = 8, anaemic control group), iron was not administered until the age of 10 days. During the study, no statistically significant differences were observed in the parameters of red blood cell count or blood plasma iron concentration between the group that received iron carboxymaltase and the group that received iron dextran. The results of haematological and biochemical examinations achieved in our study show that the application of iron carboxymaltase was successful in preventing iron deficiency anaemia in piglets. The results indicate comparable efficacy of iron carboxymaltase and iron dextran. |
Effect of leaf-to-fruit ratio on kernel quality formation of walnut treesOriginal PaperLinhui Feng, Xian’an Yang, Shiwei Wang, Honglong Hao, Cuifang Zhang, Yicheng Gao, Yuqi Wang, Yusufu Alifu, Wenhui ZhaoHort. Sci. (Prague), 2025, 52(3):201-210 | DOI: 10.17221/69/2024-HORTSCI The study focused on the relationship between leaf-to-fruit ratio (LFR) and walnut kernel quality in Juglans regia ‘Wen 185’. It was investigated how LFR influences single kernel weight, the contents and percentages of organic matter in kernels, the 13C distribution proportion (13CDP) in crude fat and protein, and the number and size of oil bodies within the kernels. A gradually decreasing LFR led to reduced single kernel weight, the contents of crude fat, crude protein, and soluble sugar dramatically (P < 0.05), with no significant changes in the percentages and (13CDP) of crude fat, crude protein, and soluble sugar (P > 0.05). Moreover, there were no significant differences in the number of oil bodies per unit area and the size of oil bodies in kernel cotyledons and endosperm storage cells among the different LFR (P > 0.05). We propose that the walnut kernel quality depends on the proportion of sugar converted into fat and protein in the kernels, that the changes in LFR affect the amount of sugar accumulated in kernels but not the proportion of sugar converted to fat and protein, and that the LFR, therefore, have no effect on the percentages of crude fat and crude protein in walnut kernels. |
