Abstract

The scientific article provides experimental material devoted to the study of the influence of green and other surgical operations in the bushes of seedless grape varieties on productivity and quality of plant yield.

It was found that the variety KishmishCherniy shows a high positive reaction to the pruning of excess shoots with thinning of leaves, as well as pruning of shoots with banding of branches and thinning of leaves. When they are carried out, the mass of the bunch and the yield from the bush in the experimental plants in comparison with control ones (without surgical operations) increases by 26,0-38,2 and 10,5-14,9%, respectively.

KishmishBeliy varieties effectively respond to such surgical operations as banding of branches with thinning of leaves and pruning of excess shoots with thinning of leaves. In this case, the increase in the mass of berries in comparison with control variant makes 21,2-41,0%, bunches – 55,7-74,7%, with an increase in yield from a bush of 33,1-36,8%.

Carrying out of green operations, providing good phytological conditions for plant life, contributes to the intensive accumulation of sugar in the berries of both grape varieties, the content of which increases by 20,8-27,2 mg/l in comparison with control variant (without green operations).
