A Sudy on the Seed Dormancy of Euonymus carnosus and Its Commutation

Euonymus carnosus Hesml is a species of autumn redleaved tree of ornamentalvalue. The physiological properties of its seed have not been reported before.In this study, observation and measurement on the permeability and inhibitors of the seed coat were made. It was confirmed that poor air permeability of the seed coat resulted in the seed dormancy andthat the seed dormancy can be removed by stratification,preferably with alternating temperature.
