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.

24-表油菜素内酯及其产物对植物总氮，蛋白质和硝酸盐氮含量的影响

研究了外源24-表油菜素内酯及其产品（Epin和Epin-Extra）的效率。与作物生产率的提高（田间试验中的块根作物和马铃薯以及植被试验中的大麦）同时，它们对植物生产的质量产生有利影响。用大麦进行的植被实验表明，表油菜素内酯对蛋白质氮的合成具有积极影响，并增加了其对谷物的参与。浓度为10 ^–9 –10 ^–7的24-表油菜素内酯的应用在实验室实验中，M导致大麦幼株中硝酸盐还原酶的活性更高，氮合成强度更高。它对氮代谢过程和某些生理机制的激活的影响使农产品的品质更高，这在田间试验中已被根作物和马铃薯的生殖器官中硝酸盐，糖，淀粉和抗坏血酸的含量所证实。
