Abstract
The germination terms of Dioscorea zingiberensis seeds on MS medium,and conducted its explants such as stem,leaf and leafstalk from tube young plants were studied. The result showed: (1)Under 25℃,the seeds treated by asepsis water had the highest germination rate on MS +gibberillin 6mg/L medium;(2)MS + 2,4-D 4mg/L medium was very perfect for the callus abduction,on which the callus abduction rates of stem,leaf and leafstalk was separately 100%,40%,20%.
