摘　　要：[Objective] This study aimed to investigate the effect of growth regulators on the camellia （Camellia oleifera） bud stock cutting and to improve its survival rate by culturing thick and strong plumule. [Method] The effects of the different growth regulators 911 rooting agent, GA3 , ABT rooting powder on the germination ratio, the average germinating speed, the diameter of plumule and the survival rate of grafting shoots of camellia were compared and analyzed. [Result] The three growth regulators could significantly improve the growth potential of the plumules. The germination rate, plumule stem and survival rates of grafted plumules treated by the three growth regulators were much better than that of control. The germinating of camellia seeds treated with 911 rooting agent, GA3 or ABT rooting powder was 5, 7 or 9 d earlier than control; the diameter of embryo was 45%, 40% or 50% larger and the survival rate was 8%, 12% or 9% higher than that of control respectively. [Conclusion] The three hormones promoted the germination, the development of the roots including the lateral root and the fibrous, and improved the survival rate of cuttings. Among them, GA3 treatment produced the best efficiency.[目的]探索生长刺激素对油茶芽苗砧嫁接的影响,以培育粗壮的胚芽来提高嫁接成活率。[方法]用生长刺激素911生根剂、GA3和ABT生根粉处理油茶种子,比较不同的处理对种子发芽率、发芽速度、胚芽粗度、嫁接成活率的影响。[结果]3种生长刺激素处理对胚芽的生长势产生了明显的影响,无论是发芽速度、胚芽生长量,还是嫁接成活率,采用激素处理的都比对照好得多。911生根剂、GA3、ABT生根粉处理的油茶平均发芽速分别比对照快5、7和9d,胚芽粗度分别比对照提高45%、40%和50%,嫁接成活率分别比对照高8%、12%和9%。[结论]使用3种激素对油茶催芽,均能促进生根和侧根、须根发育,提高其嫁接成活率,其中GA3处理效果最好。
