The article is devoted to the aspects of the use of hormonal preparations in agricultural crop production. Plant growth processes are largely determined by internal factors among which hormonal regulation occupies the main place. The study of plant growth patterns is of great importance for the development of methods of modeling, programming and forecasting the yield of agricultural plants. Growth regulators of hormonal nature have shown their effectiveness in solving many problems: in cultivation of various agricultural and technical crops, for example, to increase plant resistance to stress factors of different nature, induction of plant defenses, sexualization, flowering, acceleration of fruit ripening, increase of valuable substances content, induction of root formation, increase of mechanical strength of tissues and most importantly increase the yield characteristics of cultivated crops. However, there is still no developed theory of directed synthesis of growth regulators of hormonal nature. The deciphering of the mechanisms of action of endogenous growth regulators is the most important task of biotechnological science. Its solution will significantly expand the opportunities for controlling plant ontogenesis and the formation of their qualitative and productive indicators, which is necessary for increasing the efficiency of agricultural production.
