Tissue Culture and Rapid Propagation of Enkianthus quinqueflorus Lour
吊钟花的组织培养技术研究

The rapid propagation of Enkianthus quinqueflouus Lour. had been established by using shoot-tip or stem with auxiliary buds as explants. The modified B5 medium as basal medium was optimum for callus induction. The callus induction rate was up to 100% cultured on B5 medium with 1 mg L-1 2,4-D. The adventitious buds were induced on B5 medium supplemented with 1～2 mg L-1 BA +0.1～0.5 mg L-1 NAA. Propagation coefficient was the highest when adventitious buds were subcultured on modified B5+1 mg L-1 BA+0.5 mg L-1 NAA. The rooting could reach 80% when adventitious buds cultured on 1/2MS+2 mg L-1 IBA, and the survival of plantlet could reach 90% after transferred into perlite bed.
