The Effect of Leaf Removal and Topping at Different Stages on the Grape Leaf Characteristics

This research was conducted in Thrace, at the latitude and longitude of 41 degrees 01' 11.41" N and 27 degrees 39' 49.14" E, in the vineyard. Different leaf removal and topping were applied to vines at different phenological development stages, and their effects on leaf characteristics were investigated on cv. Michele Palieri. The trial was conducted for two years in the 2018-2019 and 2019-2020 development periods. In the experiment, there were three different phenological stages (Berry Set, Bunch Closure, Veraison) and four different applications (Control, Topping, Leaf Removal, Leaf Removal+Topping). To determine the leaf area characteristics, phenological stages, average main leaf and lateral shoot leaf area (cm2), main leaf and lateral shoot leaf area per vine (cm2 vine-1), total leaf area per vine (cm2 vine-1), yield per decare (kg da-1), leaf area per one-kilogram grape (cm2 kg-1), leaf area exposed to the sunlight (m2 da-1) and sun-exposed leaf area per kilogram grape (cm2 kg-1) were made. As a result, in the province of Tekirdag, it was determined that the Leaf Removal and Leaf Removal+Topping applications carried out in the Bunch Closure period of the table grape cv. Michele Palieri increased the leaf area.
