[Objective] To examine the effect of different concentrations of IBA and NAA as well as different cutting time on cutting rooting of Rabdosia ternifolia( D. Don) Hara branch. [Methods] With the branches in different parts of Rabdosia ternifolia( D. Don) Hara as experimental material,different concentrations of growth hormones IBA and NAA were used for treatment. [Results]200 mg. L- 1IBA and NAA had better treatment effect than other concentrations of IBA and NAA,and the variance analysis results show that there was a significant difference in rooting rate between the treatments; IBA treatment had the greatest effect on rooting rate,the effect on root length and root number was not obvious,but it could significantly increase root length and root number. [Conclusions]During May cutting,the branches soaked with 200 mg·L- 1IBA and 200 mg·L- 1NAA for 12 h had the best rooting effect,and the rooting rate reached as high as 75. 8%.
