The optimal combination of medium was modified DCR+2.0 mg/L6-BA, on which 74% explants was induced , average inductive rate of propation was 6, and the highest rate of propagation was 11.(3) Different treatment of explants also had important influence.

• 较为适宜的培养基组合为改良DCR+2.；0mg/L 6-BA；诱导率可达到74%25；平均增殖系数为6；最大的增殖系数可达到11。
