摘　　要：为了比较延边地区引种葡萄品种的耐寒性,对蜜汁、京亚等8个葡萄品种的休眠期枝条进行了低温处理,以自然越冬为对照。综合电导率、半致死温度(LT50)、自然越冬后冻害发生情况得出:京亚和蜜汁的耐寒性最强;无核白次之;奥古斯特和里扎马特的耐寒性最差;其他品种居中。In order to compare the chilling resistance of several introduced grape varieties in Yanbian area, the branches of 8 grape varieties such as Mitsushiru,Jingya,which were all at the period of dormancy, were conducted under the low temperature treatment,with natural overwinter as a control. Considering conductivity, semilethal temperature and the degree of the frozen injury due to natural overwinter synthetically,we concluded that the chilling resistance of Jingya and Mitsushiru is the strongest;Sultanin follows;August and Rizanat are the worst.
