Abstract

his study was carried out in 5 BB rootstock grafted on Horoz Karasi and Gök üzümgrape varieties (Vitis vinifera L.) during the 2010 growth season. Effects of 1/3 clusterreduction (CR), 1/3 CR + herbagreen (HG) and 1/3 CR + humic acid (HA) applications on grape yield and quality of cultivars were examined. The results showed that 1/3 CR + HA application increased grape yield, berry weight, berry redand blue color intensity values of Horoz Karasi grape variety and 1/3 CR application increased grape yield and maturity index values of Gök üzüm grape variety.

 

Key words: Vitis vinifera L., grape yield, quality, cluster reduction, humic acid, herbagreen.
