STUDING ROOTSTOCKS FOR CHERRY CROPS WITH KERNELS IN TAJIKISTAN HISSAR VALLEY CONDITION
This article is written about studying rootstocks for stone fruit crops sweet cherry in characteristics and imposes specific requirements for grows and development, both during reproduction in the mother liqueur and during the growth of trees in the garden. So, for example, the root system in sour cherry is more superficial than of wild sweet cherry. Therefore, the care of trees grafted on sour cherry and wild sweet cherry, the uterine bushes of these rootstocks cannot be same. In addition, among the individual groups of rootstocks are very significant differences. In Gissar valley conditions of Tajikistan used as rootstocks Lyubskaya-15, Podbelskaya and Shpanka. High specificity of sweet cherries varieties depends on the rootstocks. High specificity of sweet cherries varieties depend on the rootstocks. In our experiments during 2013-2018 phonological observation had been carried out to study their winter resistance, yield and fruit quality, for the own - rooted and grafted plants were treated the same throughout the entire observation period. At the same time, a certain ratio between the leaf system of the rootstock and the graft mintained by trimming the crown. Because of the evolution and selection, we have identified the wild cherry forms, which distinguished by the highest yields. The most valuable varieties are pink Napoleon, Bagration; Compotes, which made from the fruits of these varieties, have received a high fasting evaluation
