DISTRIBUTION OF VEGETATIVE MASS BETWEEN ABOVE GROUND AND UNDERGROUND PARTS OF APPLE TREES
Distribution of vegetative mass in different parts of apple trees by full extraction of trees from soil for Orlik and Spartan on rootstock 62-396 was evaluated. It is determined that more rigorous trees of Spartan had twice more general dry vegetative mass, in 2,4 the total length annual shoots increase in comparison with non-vigorous trees of Orlik. The weight of roots of Spartan is 34,9 % of total vegetative mass of the tree, for Orlik - 25,5 %. The share of coronal roots of the root system for Spartan was 9, 7 %, and for Orlik - 34,0 %.
