The Effect of 24-Epibrassinolide and Its Products on the Content of Total, Protein, and Nitrate Nitrogen in Plants

详细

The efficiency of exogenic 24-epibrassinolide and its products (Epin and Epin-Extra) has been studied. Parallel to an increase in crop productivity (root crops and potatoes in field experiments and barley in vegetation experiment), they exert a favorable effect on the quality of plant production. The vegetation experiment with barley has shown a positive impact of epibrassinolide on the synthesis of protein nitrogen and a rise in its participation in grain. Application of 24-epibrassinolide in the concentration of 10^–9–10^–7 M at laboratory experiments has resulted in higher activity of nitrate reductase and more intense nitrogen synthesis in juvenile plants of barley. Its effect on processes of nitrogen metabolism and activation of some physiological mechanisms makes higher the quality of agricultural products, which is confirmed with by the content of nitrates, saccharides, starch, and ascorbic acid in reproductive organs of root crops and potatoes at field experiments.
