The behavior of some sour cherry varieties in the southern part of the country

Abstract

The sour cherry species is of great economic importance due to the quality of the fruits together with the agrobiological particularities of the trees to capitalize on a great diversity of pedoclimatic conditions from the plains to the hills. A major contribution is made by the adaptability of varieties to specific growing conditions. The varieties Vrâncean and Crișana 2 showed very well developed roots at a depth of 40 cm, the roots absorbing soil fertilizers better, an aspect that helps the growth and development of the trees. We found a higher percentage of roots in Mocănești varieties 16 - 24.8%, Schattenmorelle - 22.5% and Vrâncean - 21.8%. The Rival variety stands out with a slightly shallower root system, however, the rooting depth as well as the way of branching is a genetic characteristic. The study of the root system of trees brings great support in solving some theoretical and practical problems.
