The effect of new synthetic pyrimidine derivatives on the growth and development of the chickpea (Cicer arietinum L.) variety Mexican was studied.The growth-regulating activity of pyrimidine derivatives was compared with the activity of phytohormones auxins, derivatives of 1H-indole-3-acetic acid (IAA) and 1-naphthylacetic acid (NAA), as well as plant growth regulators, derivatives of sodium and potassium salts of 6-methyl-2-mercapto-4- hydroxypyrimidine (Methyur and Kamethur), N-oxide2,6-dimethylpyridine (Ivin).The most biologically active synthetic compounds among pyrimidine derivatives were selected, which showed auxin-like, Ivin-like, Methyurlike and Kamethur-like regulatory effects on the growth and development of the shoot and root of chickpea plants. An analysis of the relationship between biological activity and the chemical structure of synthetic pyrimidine derivatives was conducted.Toimprove the growth and development of the chickpea (Cicer arietinum L.) variety Mexican, the application of selected synthetic pyrimidine derivatives, as well as plant growth regulators Methyur, Kamethur and Ivin is proposed.
