Değişik Gelişme Dönemlerinde Yapılan Yaprak Alma ve Uç Alma Uygulamalarının Asma Yaprak Alanı Özelliklerine Etkisi

Abstract

This research was conducted in Thrace, at the latitude and longitude of 41° 01' 11.41" N and 27° 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 3 different phenological stages (Berry Set, Bunch Closure, Veraison) and 4 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 order to obtain high quality table grapes in the cv. Michele Palieri in Tekirdag province, Leaf Removal and Leaf Removal+Topping applications were recommended.
