Abstract:
Styrax obassia seeds were used as material.In this study,seed dormancy reasons were investigated by permeability of testa,and the bioassay of extracts from different parts of seeds were determined.The seeds were treated by cold stratification,and the content of endogenous hormones,such as ABA,GA,IAA and ZR,were measured to study the effect of endogenous hormones on seed germination.The results showed that the testa had some difficulty in permeability and mechanical restraint.There were germination inhibitions in all parts of seeds,and the order of inhibitory effect was testa
