Investigation of the formation of the harvest and the quality of fruit of grapes with different methods of pruning the vine

Abstract

The importance of the influence of the methods of pruning the vines of grape depending on the varietal features on the formation of the harvest and the quality of the grapes are substantiated. A technique for investigating the influence of the length of the vine pruning on the qualitative indices of grapes is offered. The methods that can be used to increase the yield of grape varieties that are zoned in Poltava region are analyzed. It is established that the coefficient of fruiting of the central buds mainly correlates with the actual yield, which makes it possible to use this connection to predict yields by grape varieties. The selected methods of pruning of grapes that would ensure a high constant yield and quality of fruits, as well as the economic efficiency of growing grapes, are substantiated and characterized.
