Fruit growing
and viticulture of South Russia
Mineral nutrition of plants
The experimental data of analysis of the content of free amino acids in the leaves of fructifying apple-tree with application of foliar fertilizing are received by method of capillary electrophoresis. The interrelation of the contents of some amino acids with the mineral composition of leaves is revealed, that suggests the possibility of diagnosing the effectiveness of foliar fertilising. Identified interrelations also can be used as additional diagnostic criterion for estimation of a physiological condition of fruit plants
Treatment of growth regulator Regalis of apple tree decreased fall of fruits, which in turn has helped increase yield and improve of fruit quality. The significant reduction of the length of internodes and decreases of size of tree annual shoots
Leaf treatment of Liberty apple plants by preparation Regalis reduced of germ shattering that contributed increasing of yield and improving of fruit quality. Treatments by growth regulator Atonik Plus in stressful conditions of summer period prevented fruit abscission and improved their quality, quadruple treatment by this preparation increased apple yield. The yield surplus on 5,1 t/ha for account of increasing of fruit average weight is obtained by 3 times treatment of preparation Reasil Universal
The directed foliar nutrition of fruit trees with available macro-and microelements in the certain period of vegetation in the connection with forecast stress-factors promote the activation of complex of protective-adaptive modifications in a plant organism. As the result, the optimization of lifetime processes is achieved in the different phases of growth and development and lastly the a more complete expression of their potential productivity even in adverse environmental conditions
The results of research of efficiency of new preparations influence on commodity qualities, chemical composition and storage ability of different apple varieties ripening in adverse weather conditions in the South of Russia are presented.
