Zhukova T. Upptake and distribution of K+ and Ca2+ cations under different nutrition condition in the winter wheat

Research object - Interplay of K+ and Ca2+ cations on the upptake and distribution their under different nutrition condition in the winter wheat. Research aim - to investigate the physiological and biochemical particularities of upptake and distribution in the compartments of cell and organs of plant and efficient use of K+ and Ca2+ cations of winter wheat plant under different nutrition condition. Research methods - physiological, biochemical, physical, statistical, economic-mathematical. Theoretical and practical resalts - contrary influence of deficit and surplus К+ and Са2+ ions in nutrient solution on the proton pump and redox potential has been established. Antagonistic interaction between uptake of К+ and Са2+ ions lead to their redistribution in the compartments of cell and organs of plant has been studied. Violation of potassium and calcium nutrient conditions result to reduce of correlation between activators and inhibitors of growth, decrease of carbon dioxide aerated exchange. It is shown that the most essential increase in yield and the improvement of grain quality were at the rise of calcium dose up to 1200 kg/ha (3 t/ha of lime), the plant were characterized by the increase of root redox-system activity, nitrogen, phosphorus, potassium and calcium transport into overground organs and the improvement of their use efficiency. Level of introduction - the resalts of the experiments are introduced on the area of 82 hectares.
