In the scientific article presents the results of research on the study of varietal cherries and artificial ways of formation of the trees to the level of photosynthetic activity of leaves with the orientation of growing trees, their intensive technology. In the research, the varieties of cherries Shubinka, Podbelskaya and Shpanka Chernaya (black) zoned in the Republic, as well as sweet cherries Volovye serdtce, Revershon and Bahor, grown on a low-growing vegetatively propagated rootstock VVA-1 and VSL-2 (Krymsky-5) were used as the object of research. As a result of the conducted research, it was found that the optimal crown system for cherry and sweet cherry varieties is the five-skeletal wall. Crown formation in these forms helps to reduce the volume of the crown to an average of 25%, at which the net productivity of leaf photosynthesis in comparison with the usual crown formation – free-growing and sparse-tiered reaches a value of 34.73 grams/m2 per day. When forming bushy forms of the crown of cherries and sweet cherries, the level of leafiness of leaves improves and the content of chlorophyll in them increases to 13.42 mg/g of raw leaf mass.
