The use of synthetic growth regulators of different physiological directions of action aimed at regulating morphogenesis and optimizing the production process is a principal modern direction of phytophysiology. Among the external plant growth regulators, the most effective is the use of growth inhibitors-retardants. The physiological action of these substances is based on blocking the synthesis or use of gibberellin in the plant (Rademacher 2016).
