Herbicides and nutrients interaction on earthworm activity in tomato cultivated soil and toxicity appraisalOriginal PaperPavani Yerra, Ponnusamy Janaki, Alaguthevar Ramalakshmi, Ramasamy Jagadeeswaran, Arjunan Sankari, Palanisamy Murali ArthanariPlant Soil Environ., 2023, 69(9):429-436 | DOI: 10.17221/223/2023-PSE While nutrients are administered through various sources and combinations, herbicides are used for pre-plant and pre-emergence weed control in the tomato fields. Therefore, a study was conducted to understand the effects of nutrient fertilisation through inorganic and organic sources along with farmers practice and the application of three herbicides, namely glyphosate, pendimethalin, and metribuzin, individually or in combinations, on earthworm activity in tomato crops. The herbicides caused a significant reduction in earthworm biomass and escapement to the lower 15 cm depth. Application of pendimethalin and metribuzin to soils inorganically fertilised with major and micronutrients resulted in low survival rates and a high ecological risk quotient. The effect was attenuated when farmyard manure was applied. The study suggests that when 2 to 3 herbicides are applied in succession and combined with inorganic fertilisers as nutrient sources, stringent measures like adding organic nutrient sources, applying the correct herbicide combination, etc., must be followed to reduce their toxicity to earthworms. This helps to protect and sustain earthworm activity and biodiversity in the soil. |
Effect of catalase on the growth performance, antioxidation, and microbial metabolism of weaned rabbitsOriginal PaperNing Liu, Yien Lin, Shuaibao Wang, Jianping WangCzech J. Anim. Sci., 2023, 68(12):508-515 | DOI: 10.17221/133/2023-CJAS The present study aimed to investigate the effect of catalase (CAT) on the growth performance, antioxidation, and microbial metabolism of weaned rabbits. Dietary treatments consisted of control and CAT supplementation at 100 (T1), 150 (T2), and 200 IU/kg of diet (T3). A total of 240 weaned rabbits were randomly assigned to 4 groups with 6 replicates of 10 rabbits each. The feeding trial lasted for 28 days. Results showed that T2 and T3 increased (P < 0.05) body weight gain and gain/feed ratio, and decreased (P < 0.05) diarrhoea rate, compared to the control. Also, serum antioxidative parameters and oxidative stress products were beneficially regulated (P < 0.05) by the dietary CAT administration. Faecal microbiota including Bacteroidetes, Prevotella, and Bifidobacterium in T2 or T3 was increased (P < 0.05). Dietary CAT with changed microbiota further influenced the metabolites from carbohydrates and proteins, evidenced by increased lactic acid, acetate, branched-chain fatty acids, and short-chain fatty acids, and decreased valerate, isovalerate, methylamine, tryptamine, putrescine, cadaverine, spermidine, and total amines. It is concluded that CAT can be used to improve growth performance by beneficially regulating the antioxidation, microbiota, and metabolites in weaned rabbits. |
Application strategy for sustainable livestock production with farm animal algorithms in response to climate change up to 2050: A reviewReviewSang-O ParkCzech J. Anim. Sci., 2022, 67(11):425-441 | DOI: 10.17221/172/2022-CJAS Global warming caused by climate change can increase heat stress and greenhouse gas (GHG) emissions, leading to food problems and livestock crises. Thus, pre-emptive responses are required to mitigate the food problems and livestock crises. The potential of a livestock crisis caused by global warming highlights the need for sustainable livestock production in response to climate change using a farm animal algorithm in order to address the population increase and avoid food problems in the future. In particular, the demand for animal-based foods has increased. Such a climate change threatens the livestock environment, production, reproductive efficiency, animal behaviour and welfare, while increasing the heat stress, livestock malodours, and GHG emissions. For these reasons, it is necessary to understand the concurrent mechanisms related to these effects of global warming, animal nutrition, animal feeding and management, animal heat stress and in ovo injection, and carbon neutral livestock. Climate-smart livestock systems are being implemented to overcome the livestock crisis caused by climate change and to maintain sustainable livestock production. This review emphasises the importance of sustainable livestock production using farm animal algorithms in response to a future livestock crisis caused by climate change in 2050. |

Colonization of ‘Sampion’ apple tree roots and rhizosphere by mycorrhizal fungi following the application of AquaGel or organic compost enriched with beneficial microorganismsOriginal PaperEdyta Derkowska, Beata Sumorok, Lidia Sas-Paszt, Krzysztof Górnik, S³awomir G³uszek, Anna Lisek, Augustyn Mika, Mateusz Fr±cHort. Sci. (Prague), 2023, 50(4):253-261 | DOI: 10.17221/1/2023-HORTSCI Apple trees of the cultivar ‘Sampion’ were planted at the Experimental Orchard of National Institute of Horticultural Research in D±browice. In a three-year experiment (2019–2021) the following fertilization combinations were applied: AquaGel (commercial hydrogel), AquaGel combined with a consortium of beneficial bacteria, AquaGel combined with a consortium of beneficial filamentous fungi, organic compost alone, compost combined with a consortium of beneficial bacteria, and compost combined with a consortium of beneficial filamentous fungi. The presence of arbuscular mycorrhizal fungi was assessed both in the rhizosphere soil and in the roots of apple trees. The results of the study indicate the most advantageous effect of compost combined with bacteria or fungi on the degree of root colonization by arbuscular mycorrhizal fungi and the formation of their spores in the soil. |
Thin layer drying characteristics of alligator pepper, ginger and turmericOriginal PaperAdebayo Olasunkanmi Salau*, Babatunde Sunday Ogunsina, Adewale Waliu Adebayo, Adekunle Felix OkunadeRes. Agr. Eng., 2023, 69(1):1-8 | DOI: 10.17221/71/2021-RAE The delightful pungency, aromatic compounds and phytochemicals in some spices make them indispensable in local food systems and native medicine, hence, driving a robust market in many parts of the world. The understanding of their drying characteristics is very important for processing and adding value, and a thin layer drying study is a proven method for achieving this. In this study, changes in the moisture content, moisture ratio, drying rate and effective diffusivity of alligator peppers, ginger and turmeric were investigated at three drying temperatures 50, 60, and 70 °C following standard procedures. Five models were proposed to simulate the drying process. Non-linear regression was used to establish the coefficient of determination (R2), sum of square error (SSE) and root mean square error (RMSE) for each model to determine the model of the best fit. The Page model gave the best fit for ginger while the logarithmic model was best fitted for alligator peppers and turmeric. The effective diffusivity ranged from 1.79–3.08 × 10–9, 8.44–9.74 × 10–9, and 4.06–6.49 × 10–9 m2·s–1 for alligator peppers, ginger and turmeric, respectively. The activation energy ranged from 16.5–22 kJ·mol–1·K–1 for the three spices. These findings promise improvement in the drying, processing and handling of spices, thereby boosting the obtainable income from the value chain. |
The effect of drip irrigation for potatoes on soil nitrogen dynamicsOriginal PaperMilan Èí¾ek, Andrea Svobodová, Jiøí Zámeèník, Pavel Kasal, Daniel VejcharPlant Soil Environ., 2023, 69(2):55-61 | DOI: 10.17221/422/2022-PSE The effects of potato drip irrigation on soil nitrogen dynamics and potato yield was studied in small-plot field trials. The trials were evaluated at during three experimental times seasons (2016-2018). Four variants of irrigation were determined, ie non-irrigated, 60, 65 and 70 ASWC (Available Soil Water Capacity). At the same time, two pre-planting fertilization dates were set at a maximum of 120 kg N/ha a in divided i.e. 60 kg N/ha before planting and 60 kg N/ha by fertigation during vegetation. Pre-planting crop fertilization or in-season fertigation did not have any significant effect on the potato yields of most variants. In all studied parameters, the positive beneficial effect of irrigation was recorded and compared to the non-irrigated control. The mitigation of drought stress in plants during the growing season is the most important advantage of irrigation. In the trials, on average across all years and varieties, the yield of the irrigated variant increased by 41 % compared to the non-irrigated variant. Maintaining optimal soil moisture has a favourable effect use of applied fertilizers. The highest mineral nitrogen content in the soil was recorded for the variant without irrigation. Considering the increased use of nitrogen fertilizers, the subsurface drip line appeared to be optimal for the creation of suitable conditions for nitrogen availability to plants in the root zone. |

Mapping of genomic regions associated with dwarfing and the determinate growth habit in horsegram (Macrotyloma uniflorum)Original PaperMala Ram Modi, Megha Katoch, Nisha Thakur, Manisha Gautam, Sunny Choudhary, Rakesh Kumar ChahotaCzech J. Genet. Plant Breed., 2023, 59(4):196-204 | DOI: 10.17221/119/2022-CJGPB Horsegram (Macrotyloma uniflorum) – an important, self-pollinated food legume, however due to limited genomic and genetic resources the genetic improvement could not be achieved as compare to other major legumes. Our work aims at finding novel microsatellite markers and their use for the construction of a linkage map from 157 individuals of F9 recombinant inbred lines (RILs) of horsegram. The determinate growth habit and plant height are important traits for its suitability for different cropping systems. The genotypic data were generated by screening 2 395 molecular markers, of which 600 (25.05 %) polymorphic markers were selected. Two-hundred eighty-seven (287) markers were mapped on ten linkage groups (LGs) at a log of odds (LOD) of 3.5 straddling 796.76 cM with 2.78 cM of marker density. For the identification of the quantitative trait loci (QTLs), the phenotypic data recorded on the RILs for the plant height and growth habit were analysed using the statistical tools JoinMap®and Windows QTL cartographer, based on the composite interval mapping (CIM) technique. Across the ten linkage groups, we detected four QTLs (LOD ≥ 2.5) for four traits. All the traits were major QTLs as indicated by the percentage of phenotypic variance (PVE) (≥ 10%) that ranged from 13.5% to 40.3%, therefore, this is very important information which can be used in marker-assisted selection (MAS). The present genomic information generated in this orphan crop, thus, provides the base for genetic improvements by devising molecular breeding strategies. |
Effects of tea planting age on soil microbial biomass C : N : P stoichiometry and microbial quotientOriginal PaperGuanhua Zhang, Wenjun Yang, Jiajun Hu, Jigen Liu, Wenfeng Ding, Jinquan HuangPlant Soil Environ., 2023, 69(5):221-229 | DOI: 10.17221/164/2023-PSE This study aimed to determine the effect of tea planting age on stoichiometric ratios of microbial biomass carbon (MBC), nitrogen (MBN), and phosphorus (MBP) and soil microbial quotient (SMQ, expressed as qMBC, qMBN, and qMBP, respectively). A chronological sequence of tea plantations (3, 8, 17, 25, and 34 years) was selected in a small watershed in the Three Gorges Reservoir Area, and a slope farmland was selected as control. The results showed that with the increase of tea plantation age, soil and microbial biomass C, N, P contents, soil C : N and C : P elevated significantly, while soil N : P overall declined; the MBC : P and MBN : P increased first and then decreased, but MBC : N varied insignificantly. The tea plantation age affected SMQ notably. qMBC first decreased and then increased following the tea planting age, while qMBN and qMBP went up in a fluctuating pattern. In this study, qMBC positively correlated with soil N : P and microbial biomass C : N : P, but negatively correlated with soil C : N and C : P; on the contrary, qMBN and qMBP negatively correlated with soil N : P and microbial biomass C : N : P, but positively correlated with soil C : N and C : P. Generally, the variations of soil microbial biomass and SMQ could reflect the soil quality of tea plantations. |
The effects of COVID-19 crisis on small family farms: Empirical evidence from Visegrad countriesOriginal PaperIvana Bla¾ková, Veronika Svato¹ová, Gabriela Chmelíková, Vojtìch Tamá¹, Eli¹ka Svobodová, Libor Grega, Simona Mi¹kolci, Jakub Piecuch, Apolka UAgric. Econ. - Czech, 2023, 69(9):366-374 | DOI: 10.17221/217/2023-AGRICECON This paper aims to investigate the effects of the COVID-19 crisis on small family farms in Visegrad countries and to provide evidence of how they have responded and coped with the crisis. We conducted our investigation using an exploratory qualitative research design based on 86 semistructured in-depth interviews with owners or responsible managers, and explored the effects of the COVID-19 pandemic on different areas of their businesses, such as human resources, supplier-customer relations, production, distribution channels or strategies, price of inputs and outputs and business models. Our findings showed that small family farms have been resilient in the face of the COVID-19 pandemic. Several negative impacts were identified, such as a decrease in sales due to the closure of accommodation and restaurant services, delays in the supply of inputs, and minor problems with the availability of workers, but those were perceived to be moderate. However, the COVID-19 pandemic created not only difficult challenges but also opportunities for small farms. Based on our findings, three main recommendations regarding the adaptability and resilience of family farms in Visegrad countries have been formulated: i) the importance of a diversification strategy, ii) selling through short supply chains, and iii) digitalisation of agriculture. |
Progression of wheat Tan spot under different bioclimatic stages and agricultural practicesOriginal PaperSalma Tissaoui, Noura Omri-Benyoussef, Hatem Chaar, Marwa Hassine, Jean-stephane Venisse, Bouzid Nasraoui, Amira Mougou-HamdanePlant Protect. Sci., 2023, 59(3):233-244 | DOI: 10.17221/103/2022-PPS Tan spot, caused by Pyrenophora tritici-repentis, is a severe worldwide wheat foliar disease and has become common in Tunisia. Two hundred wheat field surveys were conducted in northern Tunisia during the 2017–2019 seasons to determine disease intensity and the correlation of the tan spot with agricultural practices and environmental factors. The disease infested 67% of the visited regions. The highest prevalence (87.5%), incidence (> 30%), and severity (> 10%) were observed in sub-humid regions, contrary to the middle semi-arid regions. Logistic regression was used to analyse the correlation of incidence and severity with various factors as independent variables. In a multiple variable model, the bioclimatic stages, variety, previous crop, humidity, and rainfall were significantly associated with tan spot incidence and severity. High incidence and severity were significantly correlated to the sub-humid regions, varieties Maâli, Razzak, Karim, and Carioca, rainfall, high level of humidity, and monoculture. The correlation between the tan spot and several environmental factors must be considered to ensure successful and sustainable disease management strategies. |
Packaging types as influencing seed quality in some soybean [Glycine max (L.) Merr.] varieties during storage periodOriginal PaperRatna Wylis Arief, Robet Asnawi, Reny Debora Tambunan, Nila Wardani, Dewi Rumbaina Mustikawati, Made Jana MejayaCzech J. Food Sci., 2022, 40(3):229-239 | DOI: 10.17221/119/2021-CJFS The post-harvest process at the storage stage is one of the most critical processes for maintaining soybean seed quality. The type of packaging and the type of material stored will affect its shelf life. One type of packaging has specific properties that are different from other types of packaging. Therefore, this study used several types of packaging materials and soybean varieties to determine changes in its quality during storage. The treatments were arranged in a 5 × 4 × 7 factorial experiment in a randomised block design (RBD) with three replications, consisting of totally 140 treatment combinations involving five different types of packaging materials. Water content, the weight of 100 grains, seedling dry weight, electrical conductivity (EC), and germination percentage were assessed monthly. The factorial analysis of variance (ANOVA) was used to compare water content, the weight of 100 grains, EC, germination, and seedling dry weight. A qualitative descriptive analysis method was employed for the temperature and relative humidity of the storage room. The results showed that Grobogan had the lowest germination percentage of 84.85% compared to the other varieties (86.97-90.82%). Plastic sack resulted in the most inferior seed quality (82.00% for plastic sack vs. 88.23-90.17% for the other containers). A more extended storage period of soybean seeds caused a decrease in soybean quality for all varieties and packaging materials. Up to 6 months of storage at room temperature, the quality of soybean seeds remained high, with the lowest germination of 80%. |
Simulating differences between forwarding short and normal-length timberOriginal PaperSimon BergJ. For. Sci., 2023, 69(11):485-496 | DOI: 10.17221/41/2023-JFS Normal log lengths in Norway are 3–6 m (NL), but occasionally there is a demand for short timber with a 2.5 m log length (ST). There are concerns that ST could reduce the forwarders' productivity. Six type stands were created based on harvester data. Different assortment distributions, conditions, and forwarders were simulated in each type stand. It was found that an additional ST assortment almost always decreased productivity (from –15.5 to +4%). Increased forwarding distance (m), more difficult driving conditions, and increased log concentration [m3·(100 m strip road)–1] decreased the productivity difference between sites with ST and NL and sites with only NL. Increased forwarder size increased the productivity difference between sites with ST and NL and sites with only NL. It is possible to load two stacks of ST on some forwarders. Such loading was more productive than loading one stack on longer forwarding distances, while the opposite was the case on short distances. However, loading two stacks of ST can lead to overloading. |
Stand structure of a juvenile Paulownia Shan Tong plantation grown in the temperate dry climate zone in Hungary – A case studyShort CommunicationFruzsina Szabó, Károly Rédei, Tamás Ábri, Elza Kovács, Lajos JuhászJ. For. Sci., 2023, 69(12):550-556 | DOI: 10.17221/90/2023-JFS In this paper, empirical relationships between diameter at breast height (DBH), crown diameter (CD), and stem number per hectare (N) were improved in a Paulownia Shan Tong plantation. Various functions of these variables were defined, focusing on growing space (Gs) and stem number per hectare. The linear crown index between CD and DBH seems to be particularly important in predicting stem number per hectare. Based on an analysis of the relationships, a CD-DBH (R2 = 0.7254) and a DBH-N graphic model (R2 = 0.7302) can be applied widely in plantation forestry. Under suitable site conditions, the investigated Paulownia hybrid can provide a higher increment in DBH than most of poplar hybrids at a certain age. The aim of this study was to explore the relationships between the Gs based on CD and DBH. These types of investigations are of fundamental importance in terms of the growing technology of tree plantations. |
Effect of exogenous selenium on mineral nutrition and antioxidative capacity in cucumber (Cucumis sativus L.) seedlings under cadmium stressOriginal PaperHongyan Sun, Xiaoyun Wang, Ni Yang, Huanxin Zhou, Yifan Gao, Jia Yu, Xiaoxiao WangPlant Soil Environ., 2022, 68(12):580-590 | DOI: 10.17221/294/2022-PSE The ameliorative effects and its mitigation mechanisms of selenium (Se) on cadmium (Cd) toxicity in cucumber seedlings were studied through hydroponic experiments. Cd and other mineral nutrient concentrations, antioxidant enzyme activities, and antioxidant contents in cucumber were studied. The results revealed that exogenous Se significantly decreased the Cd concentrations in all tissues, especially in the leaves. Moreover, exogenous Se (Cd + Se) could increase Zn, Na, leaf Cu, stem/root Fe, stem/root Ca, and stem/root Mg concentrations; and reduce leaf Mg concentration, compared with Cd alone treatment. Additionally, the application of Se ameliorated the toxicity of Cd by harmonising the activities of antioxidase, such as Cd + Se treatment reduced Cd-induced increase of superoxide dismutase, glutathione peroxidase, leaf/stem ascorbate peroxidase (APX) activities, which resulted in the significant decrease of the content of hydrogen peroxide, and malondialdialdehyde; increased root APX, and glutathione reductase activities. In addition, the content of nonenzymatic antioxidants such as root-reduced glutathione and oxidised glutathione was significantly increased by adding Se under Cd stress. Also, exogenous Se enhanced the total antioxidant capacity in terms of cupric-reducing antioxidant capacity and decreased total phenols, flavonoids, and leaf/root proline contents under Cd stress. In general, 3 μmol/L Se was conducive to plant growth and improved the cucumber's ability to alleviate Cd stress. |
Prediction of saturated hydraulic conductivity Ks of agricultural soil using pedotransfer functionsOriginal PaperKamila Bá»ková, Svatopluk Matula, Markéta Miháliková, Eva Hrúzová, David Kwesi Abebrese, Recep Serdar Kara, Cansu AlmazSoil & Water Res., 2023, 18(1):25-32 | DOI: 10.17221/130/2022-SWR The determination of the saturated hydraulic conductivity Ks on a field scale presents a challenge in which several variables have to be considered. As there is no benchmark or reference method for the Ks determination, the suitability of each available method has to be evaluated. This study is aimed at the functional evaluation of three publicly available types of pedotransfer functions (PTFs) with different levels of utilised predictors. In total, ten PTF models were applied to the 56 data sets including the measured Ks value and the required predictors (% sand, silt and clay particles, dry bulk density, and organic matter/organic carbon content). A single agricultural field with a relatively homogenous particle size distribution was selected for the study to evaluate the ability of the PTF to reflect the variability of Ks. The correlation coefficient, coefficient of determination, mean error, and root mean square error were determined to evaluate the Ks prediction quality. The results showed a high variability in Ks within the field; the measured Ks values ranged between 10 and 1261 cm/day. Although the tested PTF models are based on a robust background of soil databases, they could not provide estimates with satisfactory accuracy unless local soil data were incorporated into the PTF development. |

Change in β-glucosidase activity in root zone of ferns under toxic elements soil contaminationOriginal PaperMilan Novák, Veronika Zemanová, Milan Pavlík, Simona Procházková, Daniela PavlíkováPlant Soil Environ., 2023, 69(3):124-130 | DOI: 10.17221/448/2022-PSE The influence of toxic elements, such as arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn), in the root zone of As-hyperaccumulator Pteris cretica 'Albo-lineata' and non-As-hyperaccumulator P. straminea, on the enzymatic activity of β-glucosidase, dissolved organic carbon (C) in soil, toxic element accumulation in fern roots, and root biomass were evaluated in a pot experiment. Ferns were cultivated in soils from the locality of Suchdol (control) and Litavka (high contamination) for six months. For all toxic elements, an increasing trend in their contents in the roots was observed with soil contamination for both ferns. Differences between ferns were observed in As and Zn accumulation. Pteris cretica had a significantly higher As accumulation than P. straminea. Zinc accumulation in the roots showed an opposite trend. A significant difference between ferns was confirmed in the dissolved organic C content. Our results showed a significantly higher content of dissolved organic C in the P. straminea root zone than in P. cretica. The significant effect of toxic elements in the soil on β-glucosidase activity was observed. Toxic elements inhibited β-glucosidase activity in the root zone of P. cretica, and an increase in P. straminea was determined in the Litavka soil. The results suggest a higher sensitivity of P. straminea to toxic element contamination in soil, leading to increased β-glucosidase activity and increased dissolved organic C content. |

Assessment of genetic variation and population structure in Iraqi barley accessions using ISSR, CDDP, and SCoT markersOriginal PaperNawroz Tahir, Djshwar Lateef, Kamaran Rasul, Didar Rahim, Kamil Mustafa, Shokhan Sleman, Avin Mirza, Rebwar AzizCzech J. Genet. Plant Breed., 2023, 59(3):148-159 | DOI: 10.17221/112/2022-CJGPB The objective of this study was to investigate the diversity of 59 accessions of barley using inter simple sequence repeat (ISSR), conserved DNA-derived polymorphism (CDDP), and start codon targeted (SCoT) markers. A total of 391 amplified polymorphic bands were generated using 44 ISSR, 9 CDDP, and 12 SCoT primers that produced 255, 35, and 101 polymorphic bands, respectively. The average values of gene diversity were 0.77, 0.67, and 0.81 for ISSR, CDDP, and SCoT markers, respectively. The mean values of polymorphism information content for ISSR, CDDP and SCoT markers were 0.74, 0.63, and 0.80 respectively. The discrimination power of the three approaches for assessing allelic diversity in barley accessions ranked as follows: SCoT > ISSR > CDDP. The barley accessions were classified and clustered into two main groups. Molecular variance analysis revealed 15, 9, and 14% variability among populations with ISSR, CDDP, and SCoT markers, respectively. The Mantel test results revealed that the three molecular marker matrices had significant positive relationships. The SCoT markers might be useful tools for selecting appropriate parents for a breeding program. |
Clinical infection of Brucella canis in a companion dog with discospondylitis in the Republic of KoreaCase ReportJH Seo, YI Oh, SH Kim, KW Seo, BJ KangVet Med - Czech, 2023, 68(7):293-298 | DOI: 10.17221/37/2023-VETMED A 2-year-old, spayed female, Bichon Frise dog was presented with reluctance to exercise, back pain, and frequent sitting down. Multiple osteolysis, periosteal proliferation, and sclerosis of the vertebral endplates of T11–13 were observed in the radiography, computed tomography, and magnetic resonance imaging. The bacterial culture of the urine specimen, the polymerase chain reaction (PCR) of the blood, and the antibody tests were positive for Brucella canis. Accordingly, discospondylitis caused by B. canis was diagnosed and doxycycline was administered. The clinical signs resolved and the culture and PCR results were negative afterwards. Doxycycline was discontinued after 6 months. The clinical signs recurred 2 weeks later, and the combination treatment of doxycycline and enrofloxacin was initiated. Though no clinical signs were observed after 9 months and the bacterial cultures and PCR were negative, the antibody titre remained at 1 : 200 or more. The dog will continue taking antibiotics until the antibody titre drops. To the best of our knowledge, this is the first case report of a clinical infection of B. canis associated with canine discospondylitis in the Republic of Korea. Although the clinical signs of brucellosis might improve with antibiotic treatment, the disease cannot be cured due to Brucella’s various strategies to evade host immune systems. Specifically, it can proliferate and replicate within the host cells, resulting in an environment that makes treatment less effective. Furthermore, owing to its zoonotic potential, owners and veterinarians should consider lifelong management or euthanasia. |

Seasonal dynamics and abundance of brown marmorated stink bug Halyomorpha halys (Stål) on four trap cropsOriginal PaperLuka Batistiè, Tanja Bohinc, Stanislav TrdanPlant Protect. Sci., 2023, 59(3):264-277 | DOI: 10.17221/2/2023-PPS The main purpose of the study was to examine the potential of crops, such as soybeans (Glycine max), sunflowers (Helianthus annuus), alfalfa (Medicago sativa), and sorghum (Sorghum bicolor), as trap crops for Halyomorpha halys. We monitored the abundance and seasonal dynamics of H. halys (egg clusters, larvae, and adults) on a selected number of various crops at 10-day intervals. The experiment was performed in two different regions of Slovenia (western and central) and in two different years (2021, 2022). The results varied depending on the location and the year. In the first experiment, data from the entire year showed that sorghum was the most attractive for H. halys adults (1.56 ± 0.12), followed by sunflowers (0.61 ± 0.05), soybeans (0.37 ± 0.03) and alfalfa (0.41 ± 0.21). In the second experiment, the abundance numbers of the pest were significantly lower compared to those of the first experiment [sorghum and soybeans (0.003 3 ± 0.002), sunflowers (0.000 3 ± 0.000 3)]. In both cases, the abundance numbers increased when all the crops entered the fruit development stage (BBCH 70+). Overall, the lower density of the H. halys population and the experimental design could also be some of the factors for such a low incidence of stink bugs in the central region of the country. More research will be needed to further develop effective control methods for this invasive pest. |

Sci., 2023, 68(10):399-406 | DOI: 10.17221/194/2022-CJAS This research paper addresses the hypothesis that the peptidoglycan recognition protein 1 (PGLYRP1) gene polymorphism (Tyr76His; dbSNP ID: ss104796364) has an influence on some performance traits and causes of culling in Polish Holstein-Friesian red-white cows. The study involved 134 cows kept on a farm in the south-west of Poland. PGLYRP1 genotypes TT, CT, and CC were detected. It was shown that compared with cows with genotypes CT and TT, the individuals with genotype CC were characterised by higher lifetime yields and higher amounts of lactation milk, fat, and protein. A beneficial effect of genotype CC, compared with genotype TT, was also noted in the case of the lifespan and, consequently, the length of the productive life and the average number of lactations. Diseases of the musculoskeletal system (genotypes CC and TT) and disorders of the reproductive system (genotype CT) were the most common causes of culling. An essential practical observation was the potentially higher susceptibility of cows with genotype CC to mastitis, which resulted in the necessity to cull over one-fifth of the animals in this group. Simultaneously, no cows in this group were culled due to low performance or metabolic, gastrointestinal, and respiratory diseases. Therefore, the PGLYRP1 gene seems to be a promising potential herd health marker; however, to consider it the main gene, it is necessary to extend the investigations to include more individuals and other breeds of dairy cattle. |

Detection and molecular identification of ‘Candidatus Phytoplasma asteris’ associated with muscari virescence of three grape hyacinth speciesShort CommunicationEmese Mergenthaler, József Fodor, János Ágoston, Orsolya VicziánPlant Protect. Sci., 2023, 59(4):389-393 | DOI: 10.17221/70/2023-PPS Grape hyacinths are popular perennial, flowering bulbous plants. In 2018, 2019, and 2020, some plants of three Muscari species showed symptoms similar to those associated with phytoplasma infection in commercial ornamental gardens in Hungary. Symptoms included virescence of flowers and yellowing of leaves. Symptomatic and asymptomatic Muscari plants were sampled at two locations to detect and identify the pathogens involved. Total DNA was extracted from the plants and used as a template in polymerase chain reaction assays to amplify 16S rRNA gene sequences and housekeeping genes (tuf, secY) with phytoplasma-specific primers. The resulting PCR products from symptomatic plants were cloned and sequenced bidirectionally. Homology searching of the obtained sequences against the GenBank database indicated the presence of 'Candidatus Phytoplasma asteris' in the three Muscari species. This is the first report worldwide of C. P. asteris phytoplasma infecting M. botryoides and M. comosum, and its first identification in M. armeniacum in Hungary. |
Differences in the removal efficiency of heavy metals in soils with different vegetation backgrounds along the China-Russia crude oil pipelineOriginal PaperShiyi Chen, Cunyong Ju, Yang Du, Tianqi Mu, Tijiu CaiPlant Soil Environ., 2023, 69(12):628-639 | DOI: 10.17221/361/2023-PSE This work discusses the differences in the removal efficiency of heavy metals in soils along the China-Russia crude oil pipeline in different vegetation backgrounds. In this paper, two representative forest types, birch forest and larch forest, were selected for replicated sampling and experimental study in the soil of disturbed and undisturbed areas along the pipeline, respectively. The results showed that after ten years of vegetation restoration, the amount of heavy metals in the soil of birch and larch forests decreased, the Cu content in the soil under the background of the birch forest was higher than that of the larch forest, while the Zn, Mn and Pb contents were lower than that of the larch forest. The order of decreasing magnitude was Mn, Pb, Zn and Cu, and the overall decreasing rate of heavy metal content in larch forest soil was more obvious. The above conclusions indicate that vegetation restoration is an effective measure to alleviate soil heavy metal pollution. |
Polyglutamic acid as a vase life improver for cut liliesOriginal PaperHuiping ZhouHort. Sci. (Prague), 2023, 50(4):308-314 | DOI: 10.17221/148/2022-HORTSCI The vase life of cut lilies is short. Improving the vase life is very important to keep this kind of cut flower fresh by using exogenous improvers. The aim of this study was to elucidate the effectiveness of polyglutamic acid (PGA) on the vase life of cut lilies, in order to introduce a new vase life improver for cut lilies. The results demonstrated that PGA significantly strengthened the antioxidant capacity by enhancing the antioxidant activities (superoxide dismutase, peroxidase, catalase, ascorbate peroxidase, glutathione peroxidase and glutathione S-transferase) and the antioxidant contents (total phenolics, total flavonoids, total anthocyanin and vitamin C), which further decreased the electrolyte leakage and the malondialdehyde and hydrogen peroxide contents. Meanwhile, the PGA significantly maintained the water balance by decreasing the water saturation deficit and increasing the relative water content and the soluble sugar and proline contents, as well as the average fresh weight change rate and average water balance value of the cut flower. Besides, the PGA significantly decreased the wilted flower numbers and increased the open flower numbers, flower diameter and the vase life of lily cut flower. The above findings provided useful information for the potential application of PGA as a new vase life improver for cut lilies. |
