Dormancy characteristics and breaking method of seeds from Epimedium wushanense

The results showed that there was no obstacle of water permeability on the test of E. wushanense, after-ripening of embryogenesis and the germination inhibitor of the seed were the main reason for the seed dormancy. The cold stratification would be an effective way for breaking of the dormancy, which could significantly promote the seed embryogenesis and increase germination rate comparing to other methods.
