Abstract

Cluster thinning and leaf removal are viticultural techniques that control yield and improve grape quality in table grapes. In this study, we aimed the effects of cluster thinning and leaf removal on anthocyanin accumulation and berry skin color characteristics in Beauty Seedless and Tekirdağ Çekirdeksizi grape cultivars. Treatments were performed at two phenological stages, one berry set, and the other veraison. Basal leaves until the first cluster on each shoot and clusters with poor berry set were manually removed. Total anthocyanin concentration was determined spectrophotometrically according to pH differential method. Berry skin color was assessed with L*, a*, b* color space based on CIE Lab color system. According to the findings, treatments increased the concentration of anthocyanin and improved color intensity in both grape varieties. Total anthocyanin content of Beauty Seedless ranged from 512.93 to 626.44 mgkg⁻¹, while berry skin CIRG index ranged from 6.74 to 6.98. The results of anthocyanin content and CIRG index value in Tekirdağ Çekirdeksizi ranged from 81.43 to 99.06 mgkg⁻¹ and from 5.16 to 5.46 respectively.

Özet

Yaprak alma ve salkım seyreltme uygulamaları, sofralık üzümlerde ürün miktarının düzenlenmesi ve ürünkalitesinin artırılmasında başvurulan bağcılık uygulamalarıdır. Bu çalışmada, salkım seyreltme ve yaprakalmanın Beauty Seedless ve Tekirdağ Çekirdeksizi üzüm çeşitlerinde antosiyanin birikimi ve kabuk renközelliklerine etkisi incelenmiştir. Uygulamalar tane tutumu ve ben düşme olmak üzere iki fenolojikdönemde gerçekleştirilmiştir. Sürgünde dipten itibaren ilk salkıma kadar olan yapraklar ve yetersiz tanetutumuna sahip salkımlar alınmıştır. Çalışmada toplam antosiyanin miktarı pH farklılığına dayalıspektrofotometrik yöntem ile belirlenmiştir. Tane kabuk rengi CIELab renk sistemine göre L*, a*, b* renkdüzleminde değerlendirilmiştir. Elde edilen bulgulara göre, uygulamalar her iki üzüm çeşidinde toplamantosiyanin konsantrasyonu ve renk yoğunluğunu olumlu etkilemiştir. Antosiyanin miktarı BeautySeedless’te 512.93–626.44 mgkg⁻¹ arasında, tane kabuğu CIRG indeksi 6.74–6.98 arasında değişmiştir.Tekirdağ Çekirdeksizi’nde ise antosiyanin miktarına ait bulgular 81.43–99.06 mgkg⁻¹ arasında değişimgösterirken, CIRG indeksi 5.16–5.46 arasında değişmiştir.
