Coumarin derivatives as antifungal agents – A reviewReviewMirjana Lonar, Dajana Gao-Soka, Maja Molnar*Czech J. Food Sci., 2023, 41(2):79-91 | DOI: 10.17221/178/2021-CJFS Coumarins and pyridines are apromising class ofnaturally occurring bioactive heterocycles with unique physical and chemical properties. Compounds containing the coumarin framework possess awide range ofpharmacological, biological, and physiological activities, which makes them important for application inmedicine, the food industry and agriculture. Among all coumarins' properties, itwas found that coumarins may prevent fungal growth, depending onsubstituents linked tothe coumarin core. Therefore, many coumarin derivatives have been investigated aspotentially powerful agents inpreventing and controlling fungal pathogens. This review summarises the latest research oncoumarins and their antifungal activity toprovide useful information for further developing more efficient coumarin-based fungicides. |
In vitro simulation ofdrought stress insome Iranian Damask rose landracesOriginal PaperHanifeh Seyed Hajizadeh, SaraRezaei, Fataneh Yari, Volkan OkatanHort. Sci. (Prague), 2023, 50(1):45-60 | DOI: 10.17221/107/2021-HORTSCI Rosa damascena is one of the oldest valuable rose flower varieties that is almost drough tolerant. However, selecting and identifying landraces that are more tolerant to drought conditions will be effective in developing the cultivation of the plant under stress. The most important step in developing drought-tolerant plants is the evaluation and identification of resistant and susceptible genotypes. In this case, an experiment was performed under in vitro conditions using five levels (0, 25, 50, 75, and 100 g/L) of polyethylene glycol (PEG) on four landraces of the Damask rose (Maragheh, Urmia, Pakdasht, and Kashan). Based on the findings, the resistance of the different landraces to a water deficit was measured by the Design-Expert software using the response level (RSM) method. The results showed that Maragheh, with the highest fresh and dry weight, total chlorophyll, chlorophyll a, chlorophyll b, proline and an increase in the superoxide dismutase activity, had a high tolerance to drought stress. Moreover, Maragheh with a decreasing leaf number, height, malondialdehyde, hydrogen peroxide and having a higher membrane stability index, showed a better defence mechanism against oxidative stress than the other landraces. Also, after Maragheh, Pakdasht had the best performance compared to the other two landraces up to 75g/L of PEG, but not as well as Maragheh at the highest level of the tested PEG. Urmia and especially Kashan probably do not have much tolerance to drought stress regarding all the results and levels of desirability. |

Ecological and human health risk assessment of tungsten and other heavy metal(loid)s in farmland around a typical tungsten mining area in southern Jiangxi, ChinaOriginal PaperQi Li, Li Tian, Xiaojun Zheng, Weijiang Chen, Buchan Zhou, Ming ChenPlant Soil Environ., 2024, 70(4):229-244 | DOI: 10.17221/344/2023-PSE The ecological and human health risks of heavy metal(loid)s (HMs) in soils around tungsten (W) mining sites have often disregarded the presence of W. In this study, we aimed to investigate the concentrations of 10 HMs (including W and other accompanying elements) in 18 agricultural soil samples obtained around a W mining site in southern Jiangxi, China. Furthermore, we determined the contamination status, source identification, and ecological and health risks of HMs in soils. Our findings revealed that HMs were extensively accumulated in soils within the study area, with the highest mean concentrations of W found. W concentrations were above background values at all sites. Multivariate analysis revealed that W mining activities, including extracting and transporting W ore, were the primary source of HMs in the soil (61.40%). The ecological risk assessment revealed that the potential ecological risk across the survey area exhibited a high risk, and the cadmium (Cd) and W should be prioritised as control pollutants for soils around the W mine site. The human health risk assessment displayed that 73.43% of children with an unacceptable non-carcinogenic risk, and W contributed the most to the overall non-carcinogenic risk (42.32%), followed by Cd and arsenic (As). In addition, 22.03% of children and 13.4% of adults were under a significant carcinogenic risk. Overall, our findings emphasise the importance of considering element W in future studies investigating the contamination of HMs around W mining areas. As such, we calculated a safe limit value for element W in soil (141.01 mg/kg)to facilitate the conservation and development of soils in W mining areas in China. Our study provides valuable information for pollution prevention and soil contamination risk mitigation in W mining areas. |
Overgrazing strongly impedes the natural regeneration of the endemic Boswellia species on Socotra IslandOriginal PaperSalem Hamdiah, Klemen Eler, Kay Van Damme, Fabio Attorre, Dario La Montagna, Michele De Sanctis, Mohammed Shaneyehen, Mohammed Amar, Theodore Danso Marfo, Petr MadraJ. For. Sci., 2024, 70(5):249-263 | DOI: 10.17221/3/2024-JFS Frankincense trees (Boswellia spp.) worldwide are affected byanumber ofthreats, including global warming and changing land management practices. Onthe Socotra Archipelago (Yemen), which harbours eleven endemic Boswellia species, grazing isgenerally assumed tobeone ofthe main threats preventing natural regeneration. Totest the impact ofovergrazing onnatural regeneration, weestablished aninsitu experiment onfour different Boswellia taxa indifferent areas ofSocotra Island. Mortality and the height increment ofseedlings were measured for aperiod oftwo/three years infive plots excluded from grazing (fenced) and infive paired control (unfenced) plots. Each plot was 50 mנ50 m insize and contained several adult trees asasource ofviable seeds. Our results show that seedling mortality was significantly higher, and seedling height increment generally (4out of5sites) lower inopen compared tofenced plots. Inthe fenced plots, the number ofseedlings for all species reached upto772, with 560 surviving seedlings. Incomparison, the control plots reached upto296 seedlings, with 176 seedlings surviving after 2–3years. The results ofour experimental study indicate that grazing directly threatens the natural regeneration ofthe endemic Boswellia on Socotra Island. However, seedling mortality remained relatively high inside the exclosures as well, which indicates that even without the pressure of livestock grazing, other impacts remain a challenge for the future conservation of the archipelago's unique frankincense trees. |
Temporal changes of soil characteristics on Ltov spoil heap, Czech RepublicOriginal PaperEnkhtuya Enkhtaivan, Oldich Vacek, Petra Vokurkov, Marko Spasi, Radim Vat, Ondej DrbekSoil & Water Res., 2024, 19(3):133-143 | DOI: 10.17221/17/2024-SWR This study aimed toexamine the changes inselected soil properties atLtov spoil heap (Sokolov, Czech Republic) and compare the current situation with the situation described twenty years ago. Atotal of110 soil samples were taken atLtov atthe same sites asin 1998. The analyses ofbasic soil characteristics involved: exchangeable soil pH (pHKCl), organic carbon content (Cox), quality ofhumic substances (A400/A600), exchangeable acidity (Ea), and two types ofaluminium contents inthe soil. Changes inall soil characteristics between 1998 and 2018 were statistically evaluated, compared, and visualized using Geographical Information Systems (GIS). Wehave observed anincrease ofpHKCl, Coxand a slight improvement in humus quality compared to the results from 1998. The temporal changes of soil characteristics were evident in the whole area, and the influence of reclamation methods was also pronounced. Soil development close to the regional common natural conditions was found in the area where agricultural reclamation measures (i.e., covering with topsoil) were carried out. Furthermore, afforestation – mainly by deciduous trees – supported the improvement of soil characteristics favourable for plant growth. High pyrite content and marshland were identified as the main causes that led to vegetation cover mortality. |
The impact ofparity, litter size and birth weight variations within alitter onpiglet pre-weaning performanceReviewNqobile Lungile Buthelezi, Bohani Mtileni, Khathutshelo Agree Nephawe, Peter Ayodeji Idowu, Mamokoma Catherine Modiba, Hezekiel Mpedi, Takalani Judas MpofuCzech J. Anim. Sci., 2024, 69(7):255-268 | DOI: 10.17221/36/2024-CJAS Sows are selected for their prolificacy. Therefore, assessing difficulties that can be associated with large litters is crucial. This review aims to highlight the factors that can affect reproductive performance such as breed, parity, litter size, environment, and nutrition. Understanding these factors can help producers make informed decisions about sow management and other aspects. Higher within-litter variation is the result of a high number of piglets born. It has been determined that large litter sizes pose a risk to animal welfare in the pig industry. Moreover, large litters bring more piglets with low birth weight leading to high pre-weaning losses. Lighter littermates struggle to get enough colostrum due to the competition with heavy littermates, which lowers their chances of survival causing high mortality. Larger litters may cause greater stress and discomfort of the sow. Therefore, applying stress-free environment and treating the sow with anti-inflammatory compounds may enhance the sow performance and consequent survival of piglets. The litter size is positively correlated with the variation in birth weight within a litter, while the average weight at birth is negatively related to litter size. Producers should therefore focus on potential management strategies that can improve piglet performance, survival and welfare such as proper supervision and adequate colostrum intake. This review highlights the historical development of the pig industry and literature on the variation in piglet weight at birth within a litter, factors influencing weight at birth, and the potential effects on the piglet performance before weaning. Also, the difficulties amongst large litters and possible strategies for managing survival in large litters were also reviewed. |
Impact of winter conditions on wind erosion susceptibility of clay soilsOriginal PaperJosef Kuera, Martin Blecha, Jana Podhrzsk, Jan Szturc, Petra Fukalov, Hana StedovSoil & Water Res., 2024, 19(4):218-228 | DOI: 10.17221/90/2024-SWR Wind erosion primarily affects sandy soil in arid areas. However, the specific winter meteorological conditions (freeze-thaw cycles) lead to the disintegration of aggregates into erosion-risk fractions even on clay soils. These changes in the winter erodibility of clay soils were investigated in an area with frequent occurrences of wind erosion in southeastern Moravia (Czech Republic, Central Europe) between the years 2014/2015 and 2020/2021. The percentage of non-erodible fraction (NEF) before and after winter was assessed. NEF was set as particles larger than 0.84 mm and also larger than 2.00 mm (based on field observations), while soils containing less than 40% NEF have the highest susceptibility to wind erosion. Autumn NEF0.84 content was 80 and 95%, indicating significant resistance to wind, and although there was a significant decrease in spring to 65%, it still exceeded the 40% threshold. Autumn NEF2.00 content of 60–70% also indicates a significant resistance to wind erosion. However, spring values were well below the 40% threshold (8 to 35%), indicating significant susceptibility to wind erosion. It showed a significant negative influence of winter on NEF2.00 content and, thus, a greater susceptibility to erosion in spring compared to NEF0.84. Our results also document vegetation efficiency on the presence of NEF. |
How to measure soil quality? A case study conducted on cropland in the Czech RepublicOriginal PaperLenka Pavl, Ji Balk, Simona Prochzkov, Ivana Galukov, Lubo BorvkaSoil & Water Res., 2024, 19(4):229-243 | DOI: 10.17221/118/2024-SWR This work presents the advantages and risks of selected soil quality criteria using data from the monitoring of agricultural soils in the Czech Republic. Soil samples were taken from 71 sites covering various soil types. Basic soil parameters and mid-infrared spectra were measured. Indicators describing the quality of soil organic matter (SOM), and soil were calculated. The results show that soil types differ significantly in the qualitative indicators of soil organic matter. More acidic soils with lower clay content contain lower proportions of aromatic and higher proportions of aliphatic organic compounds than neutral soils with higher clay particles content. These soils differ little in total carbon content and C/N ratio but considerably in C/clay ratio. Cambisols are the least degraded soils in the Czech Republic in terms of C/clay ratio, which is controversial in many respects. The results indicate that more aliphatic organic matter is important for the SOM content in the upper part of the agricultural soil, and more aromatic organic matter is mainly bound to the clay fraction. The results raise questions about the suitability of uniform C/clay target values proposed in European legislation as a criterion for assessing soil degradation due to carbon loss. |
Effect of surface-applied compost on soil propertiesOriginal PaperMarkta Mihlikov, Kamila Bkov, Petr Dvok, Recep Serdar Kara, Cansu Almaz, Martin Krl, Barbora Badalkov, Kvtue Hejtkov, Vladimr Man, PatriSoil & Water Res., 2025, 20(2):71-83 | DOI: 10.17221/148/2024-SWR The positive influence ofsurface compost application without incorporation onsoil physical properties isknown but remains underexplored. This study evaluated the effects ofsurface-applied stable and mature compost onbasic soil physical and chemical properties, including saturated hydraulic conductivity, aggregate stability, and penetration resistance. Conducted asasemi-operational field experiment intwo Czech agricultural sites (A: Blatnice atJaromice and B: Jevko; Cambisols with loam and silty clay loam textures, respectively), the plots were treated with compost (SCA) atrates of4 30t/ha (A) and 1 200t/ha (B) orleft untreated ascontrols (CON). The crops were wheat (A), maize (A, B) and intercrops. Surface compost application began in2022, and soil sampling and field measurements were conducted during the 2023 and 2024 growing seasons. Results showed significant positive changes (P < 0.05 orlower) inSCA plots compared toCON. Soil organic matter content increased by27.8% atlocality Aand by58.1% atlocality B, while saturated water content increased by5.3% (A) and 11.0% (B) inthe latter season. Similarly, pH and electrical conductivity showed increases. Water-stable aggregate ratios increased by6% to30% atboth localities. Dry bulk density decreased by10.5% (A) and 15.7% (B). Improvements insaturated hydraulic conductivity (by 28.6%) and penetration resistance were observed only atlocality B. These findings show the potential ofsurface-applied stable and mature compost toenhance soil properties effectively. |

Understanding gully erosion development through a geomorphological approachOriginal PaperEdwin Maulana, Junun Sartohadi, Muhammad Anggri SetiawanSoil & Water Res., 2025, 20(2):84-92 | DOI: 10.17221/92/2024-SWR This study aims to identify the gully erosion typology and development using a geomorphological approach. Gully geomorphology features were executed using combined photogrammetric approaches: aerial photography (unmanned aerial vehicle, UAV) and terrestrial photo data (structure from motion, SfM). The UAV data are used to identify the gully orientation, while SfM derives the geomorphological features in the gully dimensions. Five canopy-free gully erosion points were selected for the UAV-SfM data acquisition. Typically, SfM data offer higher resolution (0.11–0.57 cm) than UAV data (0.61–2.08 cm). Modelling using SfM can provide an in-depth illustration of gully dimensions such as rill erosion, scars, and cracks. The findings demonstrate that the gully depth and width are larger on the middle slope. This phenomenon is influenced by the strength of the flow and the silt transported by the water, which reaches a peak on the middle slope. The lower slopes have a solid form since the power of the flow weakens as it transports the accumulated silt from the upper and middle slopes. The study’s findings can be relied on to guide communities in strengthening the gully body in the middle slope. Furthermore, the findings can be tested and adopted globally with comparable typologies. |
Rainfall variability in the mountain forest catchments of ern Opava tributaries in the Jesenky MountainsOriginal PaperVt rmek, Vra Fadrhonsov, Kateina Neudertov HellebrandovJ. For. Sci., 2025, 71(3):138-148 | DOI: 10.17221/96/2024-JFS Anunprecedented bark beetle outbreak has led toasignificant decline inforest cover inCentral Europe inthe last 10 years, affecting anarea estimated atmore than 200 000 ha inthe Czech Republic. Among the many ecological threats associated with extensive clearings, the potential alteration ofhydrological processes isone ofthe most important. Therefore, after 2022, the precipitation–runoff balance inthree catchments inthe Jesenky Mts. area was studied. This study focuses onthe rainfall variability within the area, which was measured using 24 rain gauges deployed tocover different altitudes aswell asthe geographical exposures ofthe mountain catchments. Precipitation data was evaluated based onseven-day totals within the frost-free period. There was asignificant increase inprecipitation with altitude (12% increase for every 100 m a.s.l.) but only inless than half (48.7%) ofthe evaluated periods. Nosignificant trend was demonstrated inthe remaining periods, and anegative trend inprecipitation with altitude was identified in8.9% ofcases. Additionally, the role ofexposure was insignificant, although atendency towards slightly lower precipitation was found for the eastern exposure ataltitudes upto1000 m a.s.l., which may berelated tothe prevailing wind direction. Weconcluded that even arelatively dense monitoring network isnot necessarily sufficient toprovide accurate precipitation data inforested catchments, especially inmountain areas. Under such conditions, the use ofcomplex models that also use radar data isrecommended. |
Impact of technical water retention on European beech (Fagus sylvatica L.) resilience and growth dynamicsOriginal PaperZdenk Vacek, Ivana Tomkov, Zdenk Fuchs, Vclav imnek, Stanislav Vacek, Jan Cukor, Luk Blek, Josef Gallo, Karel Zlatuka, Martin DuchanJ. For. Sci., 2025, 71(3):124-137 | DOI: 10.17221/92/2024-JFS Global climate change (GCC) isputting increasing pressure onforest ecosystems, leading tomore frequent disturbances such aspest outbreaks and other climate-related stressors, all ofwhich threaten forest stability. This study examines how different technical water retention measures (infiltration pits) can enhance the resilience ofEuropean beech (Fagus sylvatica L.) tothese climatic challenges, focusing ontheir impact onradial growth, sap flow, and acclimatisation tomoisture conditions attwo sites inCzechia (430–440 m a.s.l.). Three treatments were compared: awater infiltration pit under aculvert mouth, aninfiltration pit without aculvert and acontrol plot without atechnical solution. Results showed that maximum daily transpiration rates ofbeech ranged between 90–120 L per day. Air temperature had astronger influence onbeech radial growth than precipitation, particularly atthe waterlogged sites. The lowest radial growth occurred inthe treatment involving awater infiltration pit under aculvert mouth, while treatments with aninfiltration pit without aculvert demonstrated notable seasonal stem shrinkage and swelling (tree water deficit – TWD), especially inearly spring. Onthe other hand, nodifferences were found between the three treatments including the control variant inthe maximum growth orthe context ofminimum TWD. In conclusion, these technical measures had limited or short-term effects on the growth and physiological processes of European beech. Despite the high costs of implementation, sap flow and dendrochronological measurements do not support the construction of infiltration pits as a means of improving water retention in forest ecosystems. |
Effects of soaking seeds with selenite on the physiological characteristics and quality of peanut sproutsOriginal PaperSanchun Lei, Qiong Wu, Yuehong Liu, Minghao Hao, Rui Liu, Feiyan Yu, Lianhe ZhangPlant Soil Environ., 2025, 71(6):387-397 | DOI: 10.17221/160/2025-PSE The aim of this study was to investigate the physiological characteristics and quality of hypocotyls in the production of selenium-enriched sprouts from peanut seeds soaked in selenium (Se) solution. Peanut seeds were soaked with 0, 2.5, 5.0, 7.5, and 10 μmol/L Na2SeO3 for 12 h and then germinated. The results showed that the selenium concentration in peanut shoots increased with increasing levels of selenite soaking, and there existed a crossroads of selenite soaking concentration (5.0 μmol/L) when selenium concentrations in cotyledons and hypocotyls were equal. Below and above this concentration, Se concentrations in shoots were radicle > cotyledon > hypocotyl or cotyledon > radicle > hypocotyl, respectively. In addition, Se significantly promoted the elongation of hypocotyls and radicles, increased shoot biomass, increased the activity of antioxidant enzymes and the concentration of antioxidants in hypocotyls, and decreased malondialdehyde levels. Moreover, Se significantly increased the concentrations of soluble sugars, proteins, free amino acids and resveratrol in hypocotyls. These results indicate that soaking peanut seeds with selenite significantly increased Se concentration, biomass, antioxidant capacity and quality of peanut shoots. This study provides a theoretical basis for the rapid and standardised production of Se-enriched peanut shoots from selenite-soaked seeds. |

The effect ofartificial reduction ofthe somatic cell count, asaviolation ofauthenticity, onmilk quality indicatorsOriginal PaperOto Hanu, Hana Nejeschlebov, Veronika Legarov, Lucie Kejdov-Rysov, Jan ha Jr., Eva Samkov, Gavin Thompson, Irena Nmekov, Marcela Klimeov (email: marcela.vyleteCzech J. Anim. Sci., 2025, 70(8):319-334 | DOI: 10.17221/90/2025-CJAS The somatic cell count (SCC) inraw milk isanimportant indicator ofhealth and hygienic quality. Artificial reduction ofthe SCC (ARSCC) inmilk, for the apparent improvement ofmilk quality for commercial reasons, isanundesirable phenomenon and aviolation ofauthenticity both inthe factual sense and legislatively. Analytical methods need tobedeveloped toidentify ARSCC aswell astoassess the effects that ARSCC may have onmilk. The aim ofthe work was toquantify the effects ofARSCC oncow’s milk asafood raw material. The results presented are some ofthe first onthe given problem. Raw bulk tank cow milk was sampled intwo experiments, each time for the whole year (2021–2022 and 2023–2024, n=66 and n=53, respectively) from herds ofCzech Fleckvieh and Holstein cows, 1 : 1. ARSCC inexperiment 1 (n=66) slightly reduced the fat content, inexperiment2 (n=53) itdid not, otherwise the milk indicators with the exception ofSCC were almost (1) and completely (2) identical. All samples were negative for the presence ofinhibitory substance residues. ARSCC under the specified technological conditions reduced SCC (1) from 772± 906103/ml to376± 630103/ml, by–51.3% (P<0.001) and (2) from 592± 798103/ml to304± 468103/ml, by–48.5% (P<0.001). Under these circumstances, the milk fermentation ability improved (1) from 28.52± 4.72SH to31.0± 4.65SH, by8.66% (P<0.001) and (2) from 32.51± 2.61SH to33.80± 2.88SH, by3.97% (P<0.001). Curd firmness was better for SCC ≤400103/ml compared tohigher SCC by5.26% (P<0.001). Nevertheless, it is not possible, for hygienic and health reasons, to allow such milk for human consumption and it is necessary to find effective identification analytical methods for ARSCC. |

Scots Pine (Pinus sylvestris L.) establishment success under climate change: Effect of site, stock type and planting timeOriginal PaperAnna Plakov, Zdenk Vacek, Stanislav Vacek, Jan Cukor, Josef Gallo, Jakub ernJ. For. Sci., 2025, 71(11):555-564 | DOI: 10.17221/84/2025-JFS Scots pine (Pinus sylvestris L.) is one of the most widespread and economically important coniferous species in the Northern Hemisphere. However, its regeneration success has recently been increasingly affected by global climate change (GCC), particularly through increasing mortality. This research aimed to evaluate the early establishment success of 30 400 bare-root and containerised Scots pine seedlings and saplings of different height classes, planted at various times on acidic and gleyed sites (479–610 m a.s.l.) across four locations in the Czech Republic. On acidic sites, seedlings exhibited 16% higher height growth and 11% lower mortality compared to gleyed sites. Containerised planting stock achieved significantly (P < 0.05) greater height growth (by 83%) and lower mortality (by 36%) than bare-root stock. For containerised material, spring plantings showed superior growth and vitality compared to autumn plantings. Planting stock height class had a stronger influence on height growth than on mortality. Based on the results, planting containerised saplings of 26–35 cm or 36–50 cm height in April is recommended for optimal establishment success of Scots pine under GCC. |

Effects oftree characteristics and climatic conditions ongall midge abundance onEuropean beech (Fagus sylvatica L.)Original PaperAdam Vle, Martin Fuln, Maan Bahadur Rokaya, Karolna BlJ. For. Sci., 2025, 71(11):565-573 | DOI: 10.17221/64/2025-JFS Asaconsequence ofclimate change and damage toconiferous forests, European beech (Fagus sylvatica L.) isthe preferred plant species for forest restoration inCentral Europe. European beech isgenerally regarded aspest-resistant. However, its vulnerability tosecondary pests, for instance, gall-forming midges, may increase with environmental stress such aslong drought periods. Weanalysed the abundance oftwo gall-forming insects, Mikiola fagi andHartigiola annulipes, onEuropean beech at26 forest sites across the Czech Republic, spanning diverse climatic and environmental conditions, using generalised linear mixed models toevaluate the effects ofabiotic factors and host tree characteristics. The results revealed that M. fagi was more abundant onyounger trees, instands with lower canopy closure, and under warmer spring conditions. Incontrast, the abundance ofH. annulipes declined indrought-affected areas. These patterns demonstrate species-specific responses ofgall midges tohost tree characteristics and climatic variables, suggesting that climate change may favour higher M. fagi abundance. Accordingly, our findings support the establishment of young beech stands under higher canopy closure, for example, beneath the shading of mature trees. |

Ultrasound-assisted ionic liquids extraction of carotenoids from Xinjiang apricots and evaluation of their antioxidant potentialOriginal PaperXiaohui Sun, Wanhui Guo, Na Jiang, Shuangyu Cao, Lei Ma, Shenghong LiuCzech J. Food Sci., 2025, 43(6):398-410 | DOI: 10.17221/26/2025-CJFS Xinjiang apricot isfavoured byconsumers because ofits distinctive aroma, high nutritive value, and abundant functional active substances. Carotenoids ofapricot are efficient antioxidants that can protect the human body from free radical attack. However, the extraction, quantification, and antioxidant activity ofcarotenoids from Xinjiang apricots have not been reported. Inthis work, ultrasound-assisted ionic liquid (ILs) extraction and optimisation ofcarotenoids from Xinjiang apricots and toevaluate their antioxidant potential. Based onBox–Behnken design (BBD), the best conditions were IL/ethanol (RIL/E) ratio of1 : 2, solid-liquid ratio (RS/L) of1 : 3, extraction time of17min and number ofextractions of3. The content ofcarotenoid extracted byultrasonic-assisted [Bmim][BF4] ILs was 32.98±0.27μg·g–1 that oftraditional extraction method was 25.05±0.35μg·g–1. Moreover, ultrasonic-assisted ILs extraction technology can shorten the extraction time, simplify the extraction steps and increase the extraction amount. Meanwhile, inorder torecover and reuse ILs, ILs-ethanolic solution was frozen attemperatures lower than –80C, allowing the ILs precipitation and separation from the ethanol solution. Meantime, the antioxidant potential offive Xinjiang apricot varieties were evaluated byDPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] assays invitro and analysed by UV–vis spectroscopy and Raman spectroscopy. The results showed Shushanggan apricot has the highest carotenoid content and the strongest antioxidant activity. In conclusion, this research further proves the advantage of ultrasonic-assisted ILs in carotenoid extraction and the potential to obtain valuable carotenoids from the apricot industries. |
The temperature sensitivity of stable organic carbon storage rises with increasing soil salinityOriginal PaperChao Li, Yanling Tian, Wei He, Yanhong Lou, Hong Pan, Quangang Yang, Guoqing Hu, Yuping Zhuge, Hui WangPlant Soil Environ., 2026, 72(1):16-27 | DOI: 10.17221/479/2025-PSE Soil salinisation is a key determinant in soil fertility decline, exerting a direct negative impact on soil organic carbon. In the context of global warming, investigating the response mechanisms of soil organic carbon pools with varying salinity levels to climate change is essential for accurately assessing the carbon cycle and emission potential of degraded soils. Based on soil samples (B1–B6) collected along a coastal salinity gradient, indoor incubation experiments were conducted at 15 C and 25 C to characterise soil respiration and its temperature sensitivity (Q10). Double-exponential models were used to simulate soil organic carbon (SOC) mineralisation, characterising active and stable organic carbon pools. The results demonstrated that the Q10 value of the stable organic carbon pool (7–8% of SOC mineralisation) was 103% higher than that of the active organic carbon pool (the initial 1% of SOC mineralisation). The Q10 value of the stable organic carbon pool was 32.6% higher at the high-salinity sites (B1, B2) than at the low-salinity sites (B4, B5). Soil organic carbon, total nitrogen (TN), and total salt (TS) were key regulators of Q10. The Q10 of the active organic carbon pool correlated positively with SOC and TN but negatively with TS, whereas the stable pool showed the opposite trends. The stable organic carbon pool exhibits a salinity-amplified Q10, implying that predictive models must account for this mechanism to avoid substantially underestimating carbon losses from degraded saline soils. |
Powdery mildew (Erysiphales) on ornamental plants in the Czech RepublicOriginal PaperMarkta Michutov, Maria Neoralov, Barbora Jilkov, Jana Vichov, Helena Pluhakov, Ivana afrankovHort. Sci. (Prague), 2026, 53(1):1-14 | DOI: 10.17221/38/2025-HORTSCI Ornamental perennials are highly popular and irreplaceable plants commonly used for enhancing public spaces and private gardens. One ofthe most frequently occurring pathogens ispowdery mildew, aparasitic fungus that covers leaves, stems, and flowers with awhitish tolight grey mycelium and reproductive structures. Itsignificantly reduces not only the lifespan ofplants but also their aesthetic value. Afield survey ofornamental plants infected with powdery mildew was conducted during the growing seasons of2021–2023 inthe Czech Republic. Thirty-nine species and cultivars ofinfected plants from 17 families were collected from botanical gardens, private gardens, and city parks, and 26 species ofpowdery mildew were identified. Species identification was based onacombination ofmorphological and PCR-based molecular analyses. The most frequently represented genus was Golovinomyces (13 species and varieties ofpowdery mildew on21 plant samples from eight families), followed byfive species ofthe genus Erysiphe onseven plant species from five families, and seven species ofthe genus Podosphaera onten plant species from five families. The species Neorysiphe galeopsidis was identified onasingle plant sample. Two new powdery mildew species (Golovinomyces savulescui, Erysiphe knautie) were identified inthe Czech Republic, and the host range ofseveral species was clarified. Golovinomyces bolayi was confirmed onCampanula lactiflora and Veronica longifolia, Erysiphe macleaye onDicentra spectabilis, and Podosphaera xantii onCalendula officinalis, Chrysanthemum sp., Dahlia pinnata, and Gerbera hybrida. |
Development ofahybrid apple population: MAS-based testing for Vf gene detection and preliminary field evaluation of its scab resistanceOriginal PaperGeorgeta Maria Guzu, Ioan Zagrai, Claudiu Moldovan, Smaranda Doina Roșu-Mareș, Luminița Antonela Zagrai, Anca Maria Chiorean, Mirela Irina CordeaHort. Sci. (Prague), 2026, 53(1):59-69 | DOI: 10.17221/196/2024-HORTSCI The apple scab, caused byVenturia inaequalis, isone ofthe most devastating diseases ofapples because itdrastically affects the aerial parts ofthe tree. Apple breeding programs frequently aim todevelop cultivars exhibiting resistance toscab. Thus, controlled pollinations were performed onapple trees in2021. The experiment was organised into ahybridisation scheme involving six apple cultivars. The scheme consists of: five female genitors (‘Auriu de Bistrița’, ‘Jonathan’, ‘Golden Delicious’, ‘Starkrimson’, and ‘Idared’) and one male genitor (‘Florina’ – donor for the Vf). Toquickly identify the Vf gene inthe early development stage ofprogenies, three pairs ofprimers were used: AM19, AL07, and VFC. The hybrid combinations with the highest percentage ofprogenies inheriting the Vf resistance gene were: ‘Starkrimson’ ‘Florina’ (59.2%), followed by‘Jonathan’ ‘Florina’ (57.1%). The hybrids that inherited the Vf resistance gene have been transferred to the field and are being further examined for their resistance against scab infections in the field, in the proximity of a natural source of the inoculum infection pressure. |
Slow-release copper efficacy study on wheat: a sustainable solution for efficient crop micronutrient deliveryOriginal PaperFarahnaz Nourmohammadian, Hessamoddin Solouki, Wilfried Dossou-Yovo, Cheng JiangPlant Soil Environ., 2026, 72(4):228-238 | DOI: 10.17221/41/2026-PSE This study evaluated a novel slow-release copper fertiliser (soileos Cu) as a sustainable alternative to conventional copper sources for improving wheat yield and nutrient use efficiency. Traditional Cu fertilisers are often limited by rapid leaching and low efficiency, especially on sandy soils with low organic matter, contributing to environmental pollution. They also exhibit low plant-use efficiency due to strong adsorption and immobilisation in soils rich in organic matter and clay minerals, thereby reducing copper availability in the soil solution and contributing to environmental pollution. A multi-scale approach was employed, including laboratory incubation, greenhouse experiments, and multi-site field trials. Copper release was quantified in water over 30 days. Greenhouse experiments compared soileos Cu with copper sulfate (CuSO4) across multiple application rates, assessing grain yield, biomass, spike count, chlorophyll index (SPAD), and tissue and grain nutrient concentrations. Field trials were conducted at four sites in Canada and the United States with contrasting soil Cu availability. Soileos Cu exhibited controlled, non-linear Cu release with substantially reduced leaching compared to CuSO4. In greenhouse conditions, soileos Cu achieved maximum grain yield, biomass, and spike number at 25–26% lower Cu application rates than CuSO4, indicating higher nutrient use efficiency. Field trials confirmed that yield responses were strongly dependent on baseline soil Cu levels, with the greatest yield increase (up to 13.3%) observed at a Cu-deficient site. Overall, soileos Cu provides an effective and environmentally responsible strategy for improving Cu nutrition and wheat productivity, particularly under Cu-limiting conditions. |
