The leaflet were used as explants to study plant regeneration,and the results showed that the adventitious bud differentiation could be effectively induced from the explants on medium MS+0.6 mg/L NAA+8 mg/L 6-BA+1 mg/L AgNO₃+3 mg/L Gln,and shoot induction rate and average number of shoots per explant was 81.03% and 5.79 respectively.The optimum medium for adventitions bud elongation was MS+2 mg/L 6-BA+4 mg/L GA₃,and the average elongation length was 1.0-2.0 cm.The rooting rate of explants on 1/2 MS+0.5 mg/L NAA+3 mg/L IBA was 86.15%,and the root was stronger,longer and had more lateral roots.After hardening-off,the survival rate and maturing rate reach to 90% and 100% respectively.
