Influences of various canopy management techniques on wine grape quality of V. vinifera L. cv. Kalecik Karasi

Abstract

This experiment was carried out to improve wine grape quality of cv. Kalecik Karasi by means of different canopy management techniques such as control (C), cluster thinning (CT), hedging (H), pro-calcium (ProCa), hedging plus pro-calcium (H+ProCa) during the 2010 vegetation period. In current study, the findings indicated that all canopy management treatments increased wine grape quality characteristics. While the effects of different canopy management techniques on quality and yield were varying, the best results concerning total soluble solids, total phenolic compound content and anthocyanin content, which are important for wine grape quality were respectively obtained from CT, ProCa, H, H+ProCa and C treatments.
