The study subject of the experience were Golden Reinders and Gala Buckeye apple varieties, grafted on M9. The trees were trained as a slender spindle system. The distance of plantation is 3.5 x 0.8 m. The experiment was conducted during the period of 2018 year. This study had the aim to determine the efficacy of different methods of thinning on the reproductive organs in the early phase. For thinning apple fruits the following variants were experimented: 1. Control – without treatment; 2. Manual thinning; 3. Geramid New, 1,2 l/ha; 4. Geramid New, 1,5 l/ha; 5. Geramid New, 1,8 l/ha. During the research the following indices were studied: the number of blossom clusters after thinning, mean fruit weight, yield, average fruit diameter and size classes based on their diameter. It was established that, the good effect of thinning was noticed in the variety Gala Buckeye after application of Geramid New, 1,2 l/h ha and the variety Golden Reinders with Geramid New, 1,8 l/ha when the size of the central flower of the inflorescence has a diameter of 4-5 mm. |
