The study subject of the experience was Regina cherry variety, grafted on Gisela 6. The trees were trained as spindle system. The distance of plantation is 4.0 x 2.0 m. The experimental plot it was placed in the orchard „Vindex-Agro” Ltd. founded in 2012 year. The research was conducted during the period of 2016 year. To study physiological processes, fruit production and its quality were experimented the following variants of treatment: 1. Control – without treatment; 2. Auxiger – 0.5 l/ha; 3. Auxiger – 0.7 l/ha. Active ingredient of Auxiger is NAD – 1.5 g/l + ANA – 0.6 g/l. Grow regulator Auxiger weresprayed one time, during the period of intensive fruit growing. During the research, it was studied the 2 7 content of chlorophyll „a” and „b”, their sum, and the content of carotenoids, average of fruits, tree production and their quality. It was established that the physiological processes, average of fruits, fruit production and its quality increase when treating with growth regulators Auxiger in dose of 0.7 l/ha duringthe period of intensive fruit growing.
