Use of pome fruit stock of apple trees for soils bioindication in the North of Central black earth economic region

In the vegetative experience, there is no close correlation between the bonitet of different types of soils and the vegetative productivity of apple seedlings. The most intensive growth on the forest soils of pome fruit stock is a characteristic feature of the biology of its wild-growing relative of the forest apple tree originated and evolved in forest ecosystems. At the same time, poor development of the root system on more fertile black earth, but intensive on forest ones, indicates the adaptation mechanism of roots in the search for nutrients and moisture.
