The object of research is the production process of grape plants in trellis-row vineyards depending on the system of vine management and exogenous hormonal regulation. The aim of research is to study, theoretical substantiation, development and industrial verification of bioadaptive technological methods of grape cultivation in trellis-row plantations at improving the management system of the vine considering agroclimatic conditions of the territory of the South of Ukraine and the method of hormonal regulation of productivity and crop quality. Research methods - field and laboratory. It is established that the vine management determines the architecture of plants, affects the functional activity of leaves, thermal and water regime of trellis-row plantations, and optimization of its parameters allows increasing the efficiency of grape cultivation in the south of Ukraine. To increase yields and economic efficiency in the establishing of vineyards in rainy conditions, it is recommended to set the following parameters of the vine management: for scion-rootstock combination Aromatnii on R x R 101-14 at a plant feeding area of 3 x 1.5 m vines forming by type of cordon with a trunk height of 120 cm; for Zagrei on the rootstock R x R 101-14 with planting schemes 3 x 1.5 m and 3 x 1 m – 80 cm and 120 cm, respectively. Increasing the yield of table grapes with parthenocarpy and stenospermocarpy berries with gibberellin, taking into account the optimal ratio between the leaf surface area of plants and crop weight (0.8 m2 of exposable leaf area per 1 kg of planned harvest) is effective in improving the quality of table grapes. To improve the quality of table grapes, increase the profitability of cultivation under irrigation on plantations of Flora and Talisman cultivars recommended treatment of inflorescences at a dose of GA 40 mg, Cishmish luchistii cultivar - 60 mg / liter. The growth regulator should be applied 3-5 days after bloom.
