Abstract:

Dormancy exists commonly in the Tilia L., which made it difficult in seedling production. The methods of dormancy breaking and seed germination enhancement had great significance for plant germplasm conservation and sustainable utilization. The existence of seedcoat, inhibitor, and development of embryo on seed dormancy were reviewed in this paper. On the basis of that, the methods of increasing seed germination rate included stratifying treatments, chemical methods treatments and embryo culture. It would be useful for future research in this field and the sustainable development of Tilia L. industry scientifically and rationally.
