摘　　要：本试验以沪培2号、沪-11和粉红亚都蜜为接穗,以华佳8号为砧木,研究葡萄砧木不同高度嫁接对各品种成活率、枝条生长量、结果性能以及抗病性的影响。结果表明:低位嫁接的成活率最高,效果最好;高位嫁接则有利于接穗品种的花芽分化与结果,并能增强接穗品种的抗病能力,霜霉病、黑痘病等病害的发病率较低。The grapevine scion/rootstock pairs of NO.2 Hupei/,Hu-11/ and Yadomi Rosa/ NO.8 Huajia were employed to study the effects of grafting heights on surviving rate,branch growth,fruiting properties and resistance to disease.The results showed that the surviving rate of low position grafting was the highest,while high position grafting was beneficial to flower bud differentiation and fruiting and could improve the scions＇ resistance to diseases.The high position grafting scions has a low incidence of downy mildew and anthracnose.
