• In order to provide scientific basis for micropropagation and cryopreservation of Gentiana straminea,plantlets were regenerated from dormant buds by cluster buds. Based on MS medium, dormant buds were inoculated in mediums containing different type and concentration of cytokinin and auxin for inducing cluster buds. 1/2MS medium with different concentration of auxin were used for inducing root. The medium of MS with 2.0 mg/L 6-BA, 0.01 mg/L NAA,30 g/L sucrose and 7 g/L agar was suitable for cluster buds' primary culture and subculture. The cluster buds inducing rate was 93. 3%. Multiple shoot clumps multiplication factor was 5.6. The medium of 1/2MS with 2.0 mg/L IAA, 0.5 mg/L IBA, 15 g/L sucrose and 7 g/L agar was suitable for root induction, its inducing rate was 93.5% with plantlets growing well. Plantlets regenerated from dormant buds of Gentiana straminea via cluster buds are established in this study.
