In this study, the seedlings of two wheat cultivars were used: drought-resistant Chinese Spring (CS) and drought-susceptible (SQ1). Seedlings subjected to osmotic stress in order assess differences response drought between resistant susceptible genotype. The aim experiment was evaluate changes physiological biochemical characteristics establish optimum level which resistance genotypes could be revealed. Plants by supplementing root medium with three concentrations PEG 6000. grown for 21 days...
The aim of the study was to assess role salicylic acid (SA) and abscisic (ABA) in osmotic stress tolerance wheat seedlings. This accomplished by determining impact acids applied exogenously on seedlings grown under hydroponics. investigation unique its comprehensiveness, examining changes other conditions, testing a number parameters simultaneously. In both drought susceptible (SQ1) resistant (CS) cultivars, significant physiological biochemical were observed upon addition SA (0.05 mM) or...
The comparative responses of ten spring wheat cultivars to water stress were investigated. Wheat plants cultured under hydroponics conditions (Hoagland nutrient) the stage three-leaf seedlings. Then, medium was supplemented with PEG (drought) or NaCl (salinity) obtain a status equal −1.5 MPa. After 2-day treatment, changes in following parameters determined: fresh and dry weight, macro- microelement accumulation, membrane injury (electrolyte leakage, lipid peroxidation) fatty acid content...
Abstract In recent years there has been growing interest in selenium (Se) as an important micronutrient not only for animals and humans but also plants. particular, its protective effect plants exposed to stress conditions suggested. spite of many studies, the mechanism Se action is fully understood. this review, possible ways interaction with factors leading optimal growth development are presented. As majority experiments have focused on effects application under induced by heavy metals,...
Abstract Brassinosteroids are plant steroid hormones important for growth and development. They include more then 70 compounds. Their physiological effect possibilities of practical use still being investigated. In this study, we evaluated the effects exogenously applied 24‐epibrassinolide, one brassinosteroids, on grain yield chemical composition (carbohydrates, proteins, fats minerals) wheat. Moreover, analysed presence brassinosteroids in newly formed wheat grains after exogenous...
Contents of ethylene, osmoprotectants, levels and forms polyamines (PAs) activities antioxidant enzymes in the leaves roots were investigated for five wheat cultivar seedlings (differing drought tolerance) exposed to osmotic stress (−1.5 MPa). Stress was induced by 2-day-long treatment plants with polyethylene glycol 6000 (PEG) or NaCl added hydroponic cultures. Nawra, Parabola Manu cv. (drought tolerant) showed a marked increase osmoprotectors (proline soluble carbohydrates, mainly glucose,...
Abstract Two kinds of barley genotypes with various water‐stress tolerances, tolerant Cam/B1 and sensitive Maresi, were subjected to 10‐day soil‐drought stress in seedling flag leaf developmental phases. After this time, both regardless the growth stage showed a decrease quantum yield PSII photochemistry (Φ ) upon treatment; however, effect was stronger plants than ones. The drought associated an increase superoxide dismutase ( SOD level genotypes, whereas seedlings, observed only for...
Abstract A response to manganese nanoparticles was studied in seedlings of two wheat cultivars and a model system plant cell membranes. Nanoparticles at concentrations 125 250 mg/ml were applied foliar. The application NPs enhanced the content Mn cells, indicating its penetration through leaf surface. stressful effect cells estimated based on changes activity antioxidant enzymes, chlorophylls starch. MnNPs evoked no significant morphology, however, an increase enzyme activity, starch...
Abstract Understanding of the physiological role mammalian hormone—androstenedione (AN)—in plants is scant and mechanisms its action at a cellular level are practically unknown. The aim this study was to investigate physicochemical biochemical background AN activity in winter wheat exposed low temperature. Cold periods important lifecycle species as they induce frost resistance further generative development. Wheat seedlings (control AN-supplemented) were acclimated 2 weeks cold then (−12...
Selenium (Se) is essential for health of humans, animals, and plants. Especially wheat a major source Se in the terrestrial food chain. In this study, an element analysis was optimized content Ca, Mg, K, S, P, Fe, Se, Mn, Cu, Zn, Mo leaves, roots, seeds were measured during growth (Triticum aestivum L. cv. Manu) Hoagland nutrient solution with 5 15 μM Na2SeO4. transported to all investigated tissues accumulated proportion used amounts. The supplementation independently concentration, weakly...
Drought is one of the most adverse abiotic factors limiting growth and productivity crops. Among them barley, ranked fourth cereal worldwide in terms harvested acreage production. Plants have evolved various mechanisms to cope with water deficit at different biological levels, but there an enormous challenge decipher genes responsible for particular complex phenotypic traits, order develop drought tolerant This work presents a comprehensive approach elucidation molecular tolerance barley...
The degree of lipid unsaturation is a parameter used to describe membrane susceptibility oxidation. This paper highlights the importance double bond distribution in hydrophobic parts layers. problem was studied by determining effects induced ozone dissolved an aqueous phase acting on layers unsaturated cholines various molecular structures, including bi-unsaturated (DOPC), mono-unsaturated (POPC) and natural origin (soy PC). destructive were quantified as ratio areas per molecule, which...
