Abstract: The experimental reslllt showed: In the mcdium of Murashigr and Shoog (MS) or Schenk and Hidebrandt (SH) added with 6-benzylamino-purine (6 -BA) at 1- 2 mg/l, the sprouting rate of buds in subculture of the buds from the adult seedling app1e trees were over 92%. Buds multiplied 5-6.8 time in fifty days. The length of shoots in a rotating liquid culture was about three times more than that in the culture on agar-medium. In the medium added with indole- 3 -butyric acid (IBA) at 0.2-0.4 mg/l, the ro-oting rate of shoots were over 80%. The suryiyal rate of transplanting tuble- plantlets were more than 85%.
