Kukhar Institute of Bioorganic Chemistry and Petrochemistry of the National Academy of Sciences of Ukraine popup.description2 In laboratory conditions, 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, thienopyrimidine and furopyrimidine on growth and development of different varieties of wheat, barley, sorghum and haricot beans during the vegetative stage was studied. The most biologically active synthetic compounds were selected in the process of screening based on the morphometric and biochemical parameters of plants, which show a growth-regulating effect similar to the phytohormones auxins and cytokinins. Optimal physiologically active concentrations of low-molecular-weight azaheterocyclic compounds were selected and the relationship between the chemical structure and biological activity of the studied synthetic compounds was analyzed. The effect of plant growth regulators, derivatives of N-oxide-2,6-dimethylpyridine (Ivin), 6-methyl-2-mercapto-4-hydroxypyrimidine sodium and potassium salts (Methyur and Kamethur) on the yield of wheat plants was investigated in field conditions. The practical use of azaheterocyclic synthetic compounds, derivatives of N-oxide-2,6-dimethylpyridine (Ivin), 6-methyl-2-mercapto-4-hydroxypyrimidine sodium and potassium salts (Methyur and Kamethur), pyrimidine, thienopyrimidine and furopyrimidine in agriculture is proposed to improve the growth and yield of wheat, barley, sorghum and bean plants.
