Determination the effects of leaf removal and topping at different times on grape growth, yield, quality and bud fertility

Research was conducted in Tekirdag Karaevli District, between 41° 01' 11.41" N and 27° 39' 49.14" E coordinates in 2018-2019 and 2019-2020 periods Michele Palieri/110R grafting combination was used as a plant materialin Reşat Koşar vineyard. The aim of research was determination of the effects of topping and leaf removal on grape growth, yield, quality and bud fertility. The were 3 different application periods [Berry Set (BS), Bunch Closure (BC), Veraison (V)] and 4 different applications [Control (C), No Leaf Removal-Topping (NLR-T), Leaf Removal-No Topping (LR-NT), Leaf Removal-Topping (LR-T)] in the research. In the beginning of research phenological stages were recorded. Shoot characteristicsin growing period, berry characteristics, cluster characteristics, leaf area characteristics, yield characteristics and bud fertility were examined. Shoot and cluster characteristics were controlled in BC period by using LR-T treatment. Berry characteristics has reach desired properties in LR-T in BS. andV periods. Cluster characteristics were improved by LR-T application in V period. Grape juice characteristics has been effected positively by using the NLR-T application in BS and, V periods. Leaf characteristics were enhancing effect by LR-NT application in BS, and BC periods. Yield characteristics were increased by LR-T application and bud fertility by LR-NT application in BC period. As a result in order to high quality and bud fertility for Michele Palieri; as an LR-T application in BC period and bud fertility in LR-NT application in BC period in Tekirdag province is proposed.
