| Abstract: | During the meristem culture of sweet potato stem-tip, seedlings can be regenerated when the sucrose concentration was among the range of 0～50%. With the increasing of sucrose concentration, the curve of induced seedling rate looked like a pendulum. Of this extent (0～50%), the adaptive sucrose concentration was not beyond 20%～30%, and the regeneration rate from sweet potato stem-tip culture could be 80% above. |
