In the conditions of the Republic of Belarus there was studied action of steroid glycosides of kapsikozin and kapsikozid on changes of hormonal (indoleacetic acid, abscisic acid, and cytokinin) and non-hormonal (phenolic compounds) plant growth regulators in barley (Hordeum vulgare) plants. The effect of steroid glycosides on the content of hormonal and nonhormonal phytoregulators of plants barley has been investigated. Steroid glycoside kapsikozin showed that the most active at the incrustation of seeds, and the spraying of plants. It promoted accumulation of IAA, ABA. cytokinins and phenolic compounds in plants of barley, which indicates that the intensification of growth processes. Research results of physiological and biochemical action of steroid glycosides showed that the nature of the stimulatory effect of the studied substances on growth, formation of generative organs, accumulation of biomass and grain productivity was connected with the formation of protein metabolism, photosynthesis, cell membranes and hormonal metabolism. Also the studied steroid glycosides rendered influence on protein and nucleic metabolism.
