THE PROBLEM OF REGULATION OF THE PROCESS OF SEXUAL DIFFERENTIATION OF INDUSTRIAL CANNABIS PLANTS

Abstract

Retrospective analysis of the impact of environmental factors and exogenous phytohormones on the formation of the sexual status of cannabis plants was made. The most obvious effect show the level of mineral nutrition, temperature and daylength. The increasing feminization contribute to ensuring a high nitrogen, low background temperatures, reduction of daylight hours. A significant role in the expression of regulatory mechanisms of sexual differentiation also play auxins, cytokinins, gibberellins, abscisic acid and ethylene. Gibberellins have shifted the sex ratio towards the increase of male flowers and plants, cytokinins and auxins stimulated the strengthening of the signs of female education and female individuals. Abscisic acid and ethylene showed a feminizing effect. Sodium selenate contributed to an increase in female sexualization.
