摘　　要：探讨接穗母树树龄、砧木地径及嫁接季节对毛红椿嫁接成活率及之后发梢的影响。结果表明:嫁接季节对嫁接效果存在影响,秋接毛红椿苗木成活率显著高于春接,但成活发梢率显著低于春接;秋接总抽梢率略低于春接,但未见显著差异;秋接新梢长度显著低于春接。砧木地径对嫁接效果存在影响,嫁接成活率、成活抽梢率、总抽梢率以及新梢长度均随地径增粗而增大,不同砧木地径分组所对应的新梢长度存在极显著差异。接穗母树树龄对嫁接存在影响,各项指标随着接穗母树树龄的增大,呈现下降趋势。总体来看,毛红椿嫁接推荐使用中幼林的优树穗条,选用粗壮苗木作砧木,在秋季进行嫁接。This study aimed to investigate the effects of age of seed tree, diameter of stock and grafting season on the grafting survival rate and sprouting of Toona ciliata var. pubescens. The results showed that the grafting season had a great influence on the grafting outcome. The grafting survival rate of T. ciliata var. pubescens was significantly greater in autumn than in spring. However, the ratio of sprouting number to grafting survival number was significantly lower in autumn than in spring. There were also slightly, non-significantly tewer sprouting of T. ciliata var. pubescens in autumn than in spring. The new shoots of autumn grafted seedlings were significantly shorter than those of spring grat）ed seedlings. The rootstock diameter influenced grafting greatly and there was a positive relationship between survival and sprouting rates and length of new shoots with the diameter of the rootstock. There was a significant difference among the length of new shoots fi＇om different rootstock diameters. The age of seed trees had a negative ton＇elation with grafting survival rate, sprouting rate and length of new shoot. In general, T. ciliata var. pubescens should be grafted in autumn with excellent tree cuttings fi＇om young and middle-aged torests, and thick seedlings as rootstock.
