Abstract Research focuses on the study of the laws of the passage of the subordinate root formation processes that determine the formation of the woody stem cuttings of the root system and the improvement of agricultural practices of individual varieties of seedlings growing Actinidia kolomikta (Rupr. et Maxim.), Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. and Actinidia purpurea Rehd. based on the technology of stem grafting in the agro-climatic conditions of the Right-Bank Forest-Steppe of Ukraine. The object of study : the process of creation of quality planting material Actinidia Lindl., depending on the varieties, characteristics, shoots, shoots and timing of harvesting and grafting concentrations of biologically – active substance KANO (10 % solution of potassium salt of α-naphthalene acetic acid).The subject was: the cultivation of own-rooted seedlings of varieties of Lasunka, Pomarancheva, Kyivska hibrydna, Kyivska krupnoplidna, Purpurna sadova, Sentiabrska, Samoplidna, Fihurna, Don Zhuan (male form). Investigations were carried out in nurseries Uman National University of Horticulture, National Park arboretum «Sofievka» NAS and private enterprise «Brusvyana». Found that the lignified stem cuttings of Actinidia Lindl. varieties have a low regenerative capacity, and their rooting depends on the variety, planting and harvesting dates on the rooting zone of the escape and its metamerically. It is shown that the improvement of the methods of stem grafting varieties of Actinidia Lindl. in the Right Bank Forest-Steppe of Ukraine can be achieved by inducing activity of rizogenenez stem cuttings of biologically – active substance auxin nature KANO with optimum application rate of 10–15 ml/l. Three-node cuttings and quadrangular, harvested from the basal part of the shoot, the processing KANO aqueous solution at a concentration of 10-15 ml/l , rooted, depending on the variety, within 89,–94,2 %, which is 40,2–44, 2 % higher than the control experiment embodiment. The selection and cultivation of varieties of blueberry seedlings in the forest-steppe zone of Ukraine is one of the important aspects of fruit growing. Their limited distribution mated with insufficient study of the biological characteristics of effective methods of cultivation and breeding. Therefore, improvement of agronomic measure accelerated reproduction of stem cuttings has theoretical and practical importance.
