摘　　要：组织显微化学特性以及扫描电镜观察显示,越冬期间,苹果枝条中淀粉粒的形态结构和转化程度与抗寒力密切相关,抗寒的山定子、八棱海棠淀粉粒小且水解彻底,不抗寒的倭锦淀粉粒大且水解不彻底;抗寒力中等的金红居中。同一时期同一品种不同组织间淀粉粒水解程度与田间抗寒力的大小表现一致。The experimental result showed that during over winter period, the morphological characteristics and change of starch grain in apple shoot were closely correlated with cold -resistance. in winter hardy species , the starch grain was smaller, disappeared later and completely.
