摘　　要：为研究红椿不同种源嫁接成活率、萌发时间和新梢生长差异,开展红椿不同种源嫁接试验。结果表明:四川攀枝花种源的嫁接成活率最高,为93.33%,最低的是广西浦北种源,嫁接成活率仅为38.89%;嫁接后萌发时间最长的是广西西林种源,为27 d,最短的为广西浦北种源,为21 d;云南富宁种源在整个试验期内,其新梢长度均高于其它5个种源。嫁接2个月后,云南富宁种源新梢的平均长度最大,为4.83 cm,新梢生长量最小的是四川攀枝花种源,为2.82 cm。In order to study survival rate,germination time and shoot growth of different provenances of Toona ciliata,grafting experiments among different provenances of T.ciliata were conducted.The results showed that grafting survival rate of Sichuan Panzhihua provenance was 93.33%,which was the highest;and that of Guangxi Pubei provenance was 38.89%,which was the lowest.The longest germination time after grafting was 27 d for Guangxi Xilin provenance,and the shortest was 21 d for Guangxi Pubei provenance.The shoot length of Yunnan Funing provenances was higher than that of the other 5 provenances in the whole experimental period.In 2 months after grafting,the average length of new shoots of Yunnan Funing provenance was 4.83 cm,which was the largest,and shoot growth of Sichuan Panzhihua provenance was 2.82 cm,which was the smallest.
