摘　　要：以15个中国马褂木无性系为材料进行嫁接试验。结果表明:切接法的嫁接成活率高于芽接法,切接法的平均成活率为53.84%,芽接法的平均成活率为43.83%。不同马褂木无性系间的嫁接成活率存在显著差异,切接成活率最高的无性系为A19-8和B15-2,切接成活率最低的无性系为B11-7;芽接成活率最高的无性系为B17-3,芽接成活率最低的无性系为B10-12和B11-6。不同无性系间嫁接苗高的生长存在显著差异,苗高最高达43.250 cm,最低为21.159 cm。This grafting experiment based on 15 clones of Liriodendron chinense. The main results were showed as follows： （1） Compared to bud-grafting, cut-grafting had higher survival rate. The average survival rate of cut-grafting was 53.84%. And the average survival rate of bud-grafting was 43.83%. （2） There were significant differences between different clones in survival rate by two grafting methods. By cut-grafting, clone A19-8 and B15-2 had the highest survival rate, clone Bll-7 had the lowest survival rate. By bud- grafting, clone B17-3 had the highest survival rate, clone B10-12 and Bll-6 had the lowest survival rate. （3） There was a significant difference between different clones in grafting material height. The highest seedling height was 43.250 cm, the lowest seedling height was 21.159 cm.
