The experimental plot is placed in the orchard “Agroparc Management” Ltd. founded in 2015. The study subject of the experience was Uifehertoi Fiurtosi sour cherry variety grafted on Mahaleb Cherry Rootstock. The trees were trained as free-growing spindle. The distance of plantation is 5.0 x 3.0 m. The tested gibberellic acid was GA4+7, product Gibbera, SL. To study the influence of the treatment on to increase the number of set fruits, enhance growth and shaping processes, three variants were experimented: 1. Control – no treatment; 2. Gibbera, SL – 0.25 l/hа; 3. Gibbera, SL – 0.50 l/hа. In the present research work, we demonstrated that Gibbera, SL product may be included in the technologic system to stimulate fruit formation, productivity and quality of fruits to administered in the dose 0,5 l/ha, up to 3 times. The first treatment should be carried out at the end of the flowering period, and the next 2 treatments at intervals of 7-10 days after the previous one.
