The Effect of Low-Growing Rootstocks on the Adaptability and Productivity of Sour Cherry Varieties (Prunus cerasus L.) in Arid Conditions

Sour cherry (Prunus cerasus L.), having a rich composition of biologically active connections and antioxidants, is gaining increasing popularity among agricultural producers. Increasing the production sour fruits requires introduction modern technology, one elements which low-growing rootstocks. For many cultures, use rootstocks has been widely studied, but there very little information on their in plantations. We studied new varieties cherries conditions dry steppe zone, where this issue had not before. L.) varieties—Toy, Memory Zhukova, Loznovskaya—are most adapted to experiments were conducted. Russian breeding forms (Krymsk, Krasnodar region), taken as rootstocks, are used for sweet avium practically never L.). The influence such parameters drought resistance, heat winter hardiness, productivity was variety–rootstock combinations. study showed that they greatest accordingly affected grafted variety with rootstock, pedigree wild species. These VSL RVL series. combinations rapid entry into fruiting season increase yield facilitated by rootstock VSL-1 VSL-2 (K5) made it possible obtain 5.8–8.1 kg/tree, depending onto them. However, necessary continue research started order fully determine qualitative quantitative identify promising ones further industrial production. This work carried out within framework topic state task Scientific Research Center Agroecology Academy Sciences No. 0713-2019-0009: “Theoretical foundations, creation competitive biotypes crops high productivity, quality, sustainability varietal technologies based latest methods technological solutions changing climate, including seed nursery breeding”.
