This study investigates selenium (Se) biofortification in four strains of the medicinal mushroom Hericium erinaceus using Se-enriched substrates to assess Se uptake, distribution, and its impact on yield. Experimental included lignocellulosic materials fortified with (0, 2, 6, 18 µg/g) form sodium selenite. accumulation varied by strain, M9521 showing highest bioaccumulation efficiency, particularly for an unknown compound, suggesting unique metabolic pathways. Other predominantly...

The study aimed at the isolation of microorganisms from aminopyralid (AP)-contaminated soil, evaluation their ability to degrade AP, and examination effects AP on microbial growth. Geotrichum candidum, Cladosporium herbarum, Candida subhashii, Paenarthrobacter nicotinovorans were isolated identified using enrichment. None those strains able 100 ppm within 2–3 weeks. In contrast, collection Pleurotus ostreatus 'Spoppo' Bacillus velezensis FZB42 reduced concentration by 35.1% 47.8%,...

Nutritional value and disease-preventive effects of cabbage are well-known. Levels the antioxidant compounds ascorbic acid (AA) glucosinolates (GSL) in new Czech cultivars were determined context different production systems. The contents AA GSLs biomass by HPLC. Individual identified according to their exact masses with sinigrin used as external standard. Artificial infection A. brassicicola generally raised levels. major (≥10 mg kg-1) glucobrassicin, sinigrin, glucoiberin. Indole aliphatic...

The infl uence of Agrisorb (water solution 1, 3, 5 g/l) on lettuce and onion seed germination was tested in diff erent moisture conditions (30 ml 15 water box).Variants with reduced level germinated much more slowly (MGT parameter) than standard variants, though erences total at the end test were insignifi cant.Treated variants seeds showed a statistically signifi cant increase energy (GE) fi rst day (GE1, both levels), but decrease second (columns GE2, ml).Higher doses slowed (GE2, 30 ml,...

The aim of this work was to evaluate the influence a hydrophilic agent (Agrisorb), added substrate for seedling cultivation (3 g Agrisorb/l substrate), on weight roots, weight, and height aboveground part, number leaves root collar diameter precultivated cauliflower seedlings (cultivar Chambord F1). Seedlings were planted under two different irrigation levels: optimal with available water capacity 80%, reduced 50%. Agrisorb following characteristics edible parts evaluated after harvest:...

ABSTRACT Pleurotus ostreatus is a widely cultivated and investigated mushroom for its economical ecological values medicinal properties. P. can be on different lignocellulosic substrates (oak sawdust, wheat straw, corn cobs many more). Optimal growth influenced not only by the composition of substrate but also amount water in it. In our study, was straw pellets with contents (60%, 65%, 70% 75%). Mycelium growth, biological efficiency (BE), moisture substrate, pH, enzymatic activities...

The aim of this study was to compare some quality parameters apples and carrots from organic integrated farming systems. In addition, the cultivars were grown in two plant densities (600 or 900 thousand plants per hectare). fructose, glucose, saccharose dry matter content seven apple (Florina, Zvonkové, Topaz, Šampion, Ontario, Melrose Idared) carrot (Afalon F1 Cortina F1) analysed by HPLC gravimetric methods, respectively. Significant differences found between samples. interactions methods...

Carrot serves as a source of health-beneficial phytochemicals for human diet whose content is affected by agroecological conditions. The effect conventional, integrated and organic farming on ascorbic acid (AA) α,β-carotene levels new carrot cultivars Cortina F1 Afalon was investigated their metabolomic profiles were measured direct analysis in real time ion coupled with high-resolution mass spectrometer (DART-HRMS). exhibited high AA total carotenes under all conditions tested that...

Effective aminopyralid herbicides are commonly used to control broadleaf weeds in cereals or pastures, but their residues straw manure may damage cultivated crops and reduce the yield. In our experiments, response of tomato plants at doses 0.6, 1.5, 3, 7.5, 15 g/ha was evaluated, extracts from treated with herbicide Mustang Forte were tested. As concentration increased, seed germination delayed by 1 3 days, compared control, all germinating seeds deformed already lowest 0.6 g/ha. With...

The study is focused on the microbial and chemical parameters of green compost in which composites based acetylated wheat B-starch maltodextrin (patented procedure) were biodegraded also lettuce grown this before after biodegradation. With a load up to 1 g per l compost, with storage period 0, 7-14, 15-20 21-147 days, mixture wiped off surface both well-preserved immediate surroundings their residues was evaluated. Microbial biomass, basal respiration (BR), metabolic quotient, dehydrogenase...

Leaves gas exchange were studied in one cucumber (Cucumis sativus L.) cultivar Harriet F1 grown under control conditions (C), defi cit irrigation (S) and straw mulch (M), as well or combination (CM SM).Cucumber plants loose soil, foil tunnel.The photosynthesis rate (P N ) transpiration (E) measured the leaves situ using portable system LCpro+.It follows from results obtained that water was 11.88 μmol CO 2 .m - .s E 1.83 mmol H O.m -2 provably decreases comparison with irrigated group...

The effect of fertilisation with fermented pig slurry on the quantitative and qualitative parameters two kinds tomatoes was assessed by means pot trials. These trials were carried out between years 2005 2008. Each trial involved four treatments, namely (a) control without fertilisation, (b) mineral fertilisers, (c) 50% nutrients in fertilisers slurry, (d) only. Besides yield parameters, following characteristics monitored: dry matter content, vitamin C titratable acidity, nitrogen compounds,...

The field experiments described here were conducted over a period of three years. effect mulching on emergence, phenophase, the weight single fruits and yield 'Elisabet F1' 'Harriet cultivars gherkins evaluated, using wheat straw, black non-woven fabric Ekocover paper mats as mulch compared to non-mulched control variant. A positive emergence was found at reduced level irrigation. use fabrics (21.01 t/ha) straw (22.92 positively affected with variant (20.97 t/ha). Reduced levels irrigation...

Herbicide substances aminopyralid and pyroxsulam are used to control broadleaf weeds in cereals. Disadvantage of this herbicides is fact, that their residues remain not only the soil, but also translocated plant tissues treated crops. released from straw like mulch by way decomposition leaching can damage strawberry. In study response strawberry plants at doses 3.75, 7.5 15 g/ha dose 3, 30 was evaluated. With increased concentration both herbicides, injury increased. A reduction fruit yield...
