The research on the tissue culture and cell suspension culture showed that thesuitable culture medium for inducing bud was MS supplemented with 1.5mg/L 6-BAand 0.1mg/L NAA, and for the generation-continuing multiplication was MSsupplemented with 1.5mg/L 6-BA and 0.2mg/L NAA. The rooting medium was1/2MS supplemented with 0.5mg/L IBA and the rooting rate was 45.0%. Plantletsurvival after transfer to sand was 52.5%.The induction rate of calli was66.7%～86.6% and the optimum medium was MS medium with 0.5mg/L 6-BA and2.0mg/L 2,4-D. The calli became smallest partical size, friable and had gooddispersion ability after 3 times successive transfer culture, the optimum medium wasMS medium with 0.2mg/L 6-BA and 2.0mg/L 2,4-D. Culturing these particles on sixkinds of MS liquid media with different hormone contents, the optimum medium wasselected basing on he change of the density of single-cell, the density of cellaggrefate and the mass of cell.
