The results showed that the kinds and concentrations of plant growth regulator, carbon source, and illumination intensity have significant effects on shoot proliferation and growth. Based on single factor and or- -1 thogonal tests, we concluded that the optimum medium for explant growing is MS+0.5 mg·L TDZ; the optimum -1 -1 medium for proliferation is MS+0.3 mg·L TDZ +0.1 mg·L 2, 4-D; the optimum medium for rooting is 1/2 MS + -1 -1 0.2 mg·L NAA.
