Effect of pruning levels in some red wine grape varieties for yield and growth parameters under Western Maharashtra conditions

摘要

In present investigation, 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 growth and yieldcontributing parameters vzl, bud sprouting percentage and bunch weight were found the maximum in severely pruned treatment i.e. 4-6/buds cane. Veraison and maturity were found early in the same treatment. However, for higher cane fruitfulness, bunches and yield each variety responded differently in different pruning treatments. The 4 buds/cane pruning treatment recorded higher yield in the variety Pinot Noir, 6 buds/cane in Syrah and Grenache, 8 buds/cane in Pinot Meunier, 10 buds /cane in Cabernet Franc and 12 buds/cane in Cabernet Sauvignon.
