OBJECT: To establish the rapid propagation system of Pinellia ternate. METHOD: The Clustered shoots were induced by the explant lamina and petiole from the terminal bud of Pinellia ternate tuber in test tube. RESULT: The plantlets could regenerate from the lamina and petiole directly without via the callus. The MS Medium with 2.0 mg/L 6-BA and 0.1 mg/L NAA was optimal for the induction of culstered shoots from explants of lamina; the MS with 2.0 mg/L 6-BA and 0.25 mg/L NAA was best for the explants of petiole; and the 1/2 MS with 1.0 mg/L KT and 2.0 mg/L NAA was the better medium for induction of roots. CONCLUSION: The regenerated rate of Pinellia ternata can improve by inducing the clustered shoots from the explants of lamina and petiole directly.
