中文摘要：

以山丁子材料为砧木，研究了不同嫁接高度对苹果成活率的影响。结果表明，不同接穗材料和不同嫁接高度均对嫁接成活率影响显著。以金红和龙丰为母本的品系与山丁子亲和性较好，成活率均达95％以上；嫁接高度为40cm和45cm时成活率最高，且此时参试的5个苹果品系的嫁接生长量最大，而低于10cm和高于50cm时的嫁接生长量较小。

英文摘要：

Malus baccata （L.） Borkh. has been used as stock in our research for the purpose to analyze the growth vigor of apple tree in the different graft height. The results showed that thereis significantly influence on graft sur- vival rate for the different materials and graftingscion. The better affinity of Malus baccata （L.） Borkh. stocks when Jinhong and Longfeng are the female parent strains, which survival rate are more than 95%. In addition, the higher survival rate when the grafting height are 40cm and 45cm, which showed the highest growth vigor for these five ap- ple strains. But when the grafting height is higher than 50cm and lower than 10cm, the growth vigor of these five apple strains decreased.
