The experimental plot is placed in the orchard “Broters” Ltd. founded in 2010 year. The study subject of the experience was Golden Reinders apple variety grafted on M 9 and MM106 rootstock. The distance of plantation is 4.0x0.8 m and 4.0x2.5 m. The research was conducted during the period of 2015 - 2016 years. The tested agents was Ethephon (Cerone 480SL), which was sprayed 3 to 4 weeks after flowering. To study the degree of differentiation of fruit buds, fruit production and its quality were experimented the following variants of treatment: 1. Control –without treatment; 2. Cerone 480 SL, 0.1 l/ha; 3. Cerone 480 SL, 0.3 l/ha. During the research, it was studied the amount of fruit formations and their type, the inflorescences, average of fruits, plantation production and their quality. It was established that, Cerone 480 SL in the dose 0.3 l/ha influence on the number of fruits formation, theamount of the inflorescences,mean fruit weight, and yield on the Golden Reinders apple variety.
