When 5ppm BA+1ppm NAA was added into the medium,65% of the stem sections formed adventitious buds,and 16.7% of the leaves formed PLB.In the MS+1ppm BA medium,PLB subculture gave multiplication,and the structures formed young plants by further culture.

• 在附加BA5ppm+NAAlppm 的培养基里；茎段不定芽诱导率为65%25；叶片PLB 诱导率为16.；7%25；用MS+BAlppm 进行PLB 继代培养可获得大量群体；进一步培养可形成完整小苗。
