DCR+6-BA2.0 mg/L was the optimal combination ,on which 74% per cent of explants induced with an average rate of propagation 6, the highest rate of propagation 8. Addition of NAA and 2,4-D would inhibit the formation of adventitious buds.

• DCR+6BA2.；0mg/L是不定芽诱导的最佳组合；外植体不定芽诱导率达74%25；平均增殖系数为6；最大增殖率为8。 NAA及2；4D的添加均不利于芽的诱导;
