Objective: To detect the germinative character of S. chinensis seeds.
Method: Using low temperature and gibberellin treatment.
Result: The breach rate of seeds was increased by both low temperature and gibberellin, but the breach on different seeds appeared untidy, which showing a character. The embryo development is normal before breaching and increased in volume rapidly after breaching.
Conclusion: The bypoplasia of embryos is not the primary reason for long dormancy of the seeds.
