The obta ined results showed that the best medium for growth was 1/2 MS medium suppleme nted with NAA 0.1 mg/L and CW 5%, and the average of the height of the pla ntlets was and 4 cm~5 cm, the average of the roots was between 4 and 5, the length of roots was 2 cm~3 cm and the plantlets grew well。 the best medium for root ing was 1/2 MS medium with IBA 0.1 mg/L and CW5%, and the rooti ng rate was 74.08%. The plantlets with 5 ~ 8 leaves, the height of 5 ~ 6 cm and 3 to 4 roots were tran sferred on to the mixture of moss, coc onut chaff and bark （2:2:1＞, and the survival rate was up to 80%DXDiTa9E3d Key
