The thesis deals with the study of constituent components of the source-drain system in apple trees as affected by nutrient defficiencies and surplusses, trunk bark-ringing and flooding. Some regularities are revealed of changes in the assimilates and macronutrients in apple tree leaves, dry matter accumulation and distribution in various organs and parts of the trees according to the variety and factor involved. The presence of fruit on trees is shown to contribute to the plant response. The results of studying the effect of disorders in the donor-acceptor relations on macronutrients, pigments and carbohydrates content in apples are recommended for practical use while finding out the demand of fruit trees in mineral fertilizers and monitoring of plantations state
