The effect of low-molecular-weight synthetic azaheterocyclic compounds, derivatives of N-oxide-2,6-dimethylpyridine (Ivin), 6-methyl-2-mercapto-4-hydroxypyrimidine sodium and potassium salts (Methyur and Kamethur), pyrimidine, thioxopyrimidine, and furopyrimidine on the growth and development of different plant varieties of wheat, barley, corn, sorghum, peas, and soybeans during the vegetative stage under normal conditions and under abiotic stress factors (drought, heat) was studied. The most biologically active synthetic compounds were selected based on morphometric and biochemical parameters of plants, which exhibit a growth-regulating effect similar to phytohormones auxins and cytokinins and increase the adaptive properties of plants to abiotic stress factors. The relationship between the chemical structure and biological activity of the studied synthetic compounds was analyzed. The practical use of synthetic azaheterocyclic compounds, derivatives of N-oxide-2,6-dimethylpyridine (Ivin), 6-methyl-2-mercapto-4-hydroxypyrimidine sodium and potassium salts (Methyur and Kamethur), pyrimidine, thioxopyrimidine, and furopyrimidine in agriculture is proposed to improve growth and increase adaptation to abiotic stress factors (drought, heat) of wheat, barley, corn, sorghum, peas, and soybean plants.
