Abstract: The wheat and liquorice seeds were disposed by electret membrane with different strengths. The experiments showed that after the seeds were treated with the proper electret membrane, the conductivities of the soaking solutions of wheat and liquorice seeds can be reduced obviously, and the activity of superoridedismutase (SOD), peroridase (POD) and catalase (CAT) enzymes of the seedlings can be increased remarkably chlorophyll content in the same unit area can be raised, and the seeding drought resistance property can be strengthened remarkably. 

Key words: electret membrane,  wheat, liquorice, activity of seeds, drought resistance property of seeding 
