Grafting Performance of Some Wine Grape (Vitis Vinifera L.) Cultivars Grafted on Different American Grapevine Rootstocks

Abstract

This study was conducted in the vine sapling production unit of "Kazova Vasfi Diren Agricultural Enterprise" located in central town of Tokat province in Turkey. The article attempted to graft five wine grape cultivars (Narince, Chardonnay, Merlot, Syrah, Öküzgözü) with five different American grapevine rootstocks (1103 Paulsen, 5BB, 41B, 110 R, 140 Ru) in order to combat mainly Phylloxera, but also provide protection against nematodes, lime and salinity-like soil-borne problems. Sapling yields of different cultivar/rootstock combinations were investigated. While the greatest sapling yield was observed in Narince/1103 Paulsen combination (98.03%), the lowest sapling yield was observed in Chardonnay/110R combination (43.64%).
