Abstract

This study was carried out in a 20 year old spur pruned Karasakız (Kuntra) vineyard during the 2003 and 2004 growth season. Vines were topped at 1, 3 and 5 nodes beyond the last cluster on the main shoot. Yield and quality parameters were analyzed to determine the effects of shoot topping. The results showed that weather conditions had more statistically important effects compared to the topping level. One (1) node topping resulted in more loss of yield due to increased vegetative growth.

 

Key words: Vitis vinifera L., shoot topping, yield, quality, canopy management, shoot topping, fruit set, yield components, fruit composition.
