Mamchur O. Physiological bases of the corn plants productivity under the actions of growth regulators Zeastimulin and Emistim C

Dissertation is devoted to the study of physiological and biochemical features of the forming of corn plants productivity cv. Transkarpatian yellow teeth-shaped in the conditions of western Forest-steppe of Ukraine on grey forest soils depending on the ground fertilizer level and action of plants growth regulators Zeastimulin and Emistim C. In the first time conducted complex research of growth regulators Zeastimulin and Emistim C action and ground fertilizer levels on the plant ontogenesis stages in relation to the physiology features of forming productivity of corn plants cv. Transkarpatian yellow teeth-shaped on grey forest soils of western Forest-steppe was conducted . It was established, that under actions of Zeastimulin and Emistim C in the leaves of corn plants cv. Transkarpatian yellow teeth-shaped accumulates more photosynthetic pigments and decreased soluble sugars content, especially at the condition of sufficient level of the soil fertilizers, that testifies high functional activity of photosynthetic system and positive changes in donor-acceptor interaction between the organs of corn plants. It was shown, that Zeastimulin and Emistim C on a background the sufficient and optimal level of the soil fertilizers contribute to reduction of duration ontogenesis stages of corn, especially in years with unfavorable weather condition, that increase productivity of corn green mass and improvement it quality
