Effect of abiotic stress factors on the traits of seeds

Original language description

The stress abiotic factors affect at winter wheat cultivars basic metabolic processes, photosynthesis, respiration, activity of enzymes, content of plant hormones, transport in plants, composition of seeds, yielding traits and seed traits and traits of sprouting plants?especially root traits: length, surface, weight, nutrient uptake, number of root tips, number of root hairs, number of lateral roots and density. This change is connected in the filial generation with tolerance to other abiotic stresses,stress tolerance, root development and chemical composition of seeds (result of change of root shoot ratio). From the results of the combustion heat calorimetry it follows, that seed stock produced from plants grown under abiotic stress conditions decrease very significantly amount of energy in 1 g of dry matter (from the 5.73 % to 8.90 %, a=0.05), which shows up decrease of germinating power and changes in plants growth in the following generation.
