Heng Zhai

Abstract

Cold resistance of 11 grape rootstocks and 5 wine grape cultivars was studied by electrolytic conductance test and cuttage test .The results were as follows: the cold resistance of grape rootstocks is stronger than that of wine grape cultivars. The cold resistance of different grape rootstocks(BetaMRH20, 5BB110R3309CSO4Fercalriparia Michx, 8BBeaumont, 1103P and wine grape cultivars (ChanbercinChardonnay, Cabernet SauvignonSyrahMerlot) were obviously different.
