摘要
通过不同激素、不同处理方法处理插穗，并研究了不同处理对插穗生根率、根长、根数的影响．试验结果表明，以IBA2500mg／L高浓度速蘸插穗生根效果最好，愈伤率、生根率最高（分别为93％、69％）；以NAA100mg／L低溶液浸泡插穗2h的生根情况最好，生根率最高，为52％．
This paper carried out a research on the relationship between cutting propagation of Sequoia sempervirens and different kinds of plant hormones and concentration of hormones, and study the effects of different treatments on the rooting rate, root length, root number of Sequoia sempervirens cuttings, The results show that： treated by NAA100mg/L for 2 hours, it had a the highest rooting rate of 52%; treated by IBA 2500mg/L for 5s, it had the highest rooting rate of 69% and the highest rate of 93%.
