Gerasko T. The influence of antioxidants on plant physiological and biochemical reactions and productivity of the winter wheat

Research object - physiological and biochemical processes in winter wheat plants, resistibility to negative abiotic and biotic factors, productivity and the quality of a grain. Research aim - to investigate the influence of presowing incrustations of winter wheat seeds with antioxidants on plant physiological and biochemical reactions, resistibility to negative abiotic and biotic factors, productivity and quality of a grain. Research methods - morphometrical, biochemical, statistucal, economic-mathematical. Theoretical and practical resalts - it is established that the complex of antioxidants and a filmer (a preparation of АОК-M) of 0.004 % concentration stimulates plant growth processes, raises the productivity of the winter wheat and its resistibility to diseases, improves the quality of a grain. Novelty - it is proved, that amplification of growth processes owing to presowing incrustations of seeds with АОК-M is caused by stimulating the activity of antioxidant enzymes and decreasing the intensityof lipid peroxidation processes in winter wheat plants. It is shown, that antioxidants in low concentration (10-6 М), which have no significant effect under normal ontogenetic conditions, reduce intensity of lipid peroxidation processes and the level of membrane damaging with simultaneous stimulating the activity of antioxidant enzymes and increasing the contents of sugars in winter wheat sprouts under negative temperatures. Level of introduction - the resalts of the experiments are introduced on the area of 25 hectares.
