Development of cherry root system on different types of rootstocks

Abstract

The studies have shown that the rootstock has a significant effect on the power of distribution of the root system of cherry. Despite the weaker development of the above-ground part of trees grafted on the Gisela 6 rootstock compared to Antipka, the root mass of trees grafted on its varieties Kordia and Regina was, on average, by 13%, and the length by 34% more. In the root structure of Gisela 6 rootstock, the main share - 77.5% - is accounted for by lobe roots with a diameter of less than 1 mm. The roots of this rootstock evenly develop the thickness of the soil horizon up to 60 cm deep, where up to 76% of the total root length is concentrated.
