Plant Growth and Development Regulators: Classification, Nature and Mechanism of Action

Abstract

Questions of the nature and mechanism of action of plant growth and development regulators (hereinafter referred to as regulators) are considered. It is proposed to use the classification of regulators depending on their original nature. Four groups of regulators are distinguished: pure chemicals, physical, biological and complex regulators. Attention is paid to the mechanisms of the relationship of artificial regulators with the natural system of regulation and integration of plants.
