Maize seeds were treated by glow discharge low-temperature plasma,and the effects of differ-ent treatment conditions(working pressure,treatment time)on the physiological properties of maize seeds were studied.The results showed that low-temperature plasma treatment under appropriate conditions could improve the germination rate of maize seeds,reduce the contact angle and fatty acid value of maize,increase the activities of superoxide dismutase(SOD)and catalase(CAT),decrease the activity of peroxidase(POD),improve the antioxidant property,and promote the growth of maize.
