Abstract

In the present investigation, the effect of five different pruning treatments (4, 6, 8, 10 and 12 buds / cane) was studied on six red wine grape cultivars (Cabernet Sauvignon, Cabernet Franc, Pinot Noir, Pinot Meunier, Syrah and Grenache). The response of each variety for yield and quality parameters viz., yield/vine, yield/ ha, juice yield/ha and Brix yield was different for different pruning treatments. The acidity was positively correlated with bud number per vine and vise a vise. The TSS, TSS ; acid ratio and berry colour were found in desirable treat in severely pruned treatments. However, interaction effect on juice recovery , TSS and pH were non significant.
