To investigate the effects of cold He plasma on seeds germination of different cultivars of wheat and barley,the seeds of wheat and barley were exposed to cold He plasma at low pressure.The results showed that at 80,100 and 120 Watt power,the effects on different cultivars of wheat seeds were different,improvements in germination were observed in Huaimai 23,Huaimai 25,Huaimai 33 and Jimai 22.At the same power,cold plasma treatment inhibited the seed germination of the barley cultivars tested,but seeds of the two barley cultivars(Daner and Gangpi)responded differently to the cold He plasma at lower power,and 30W was the most effective power for Daner and Gangpi.Analysis on the timeliness of the plasma treatment indicated that there were no significant changes for the germination indexes of Huaimai 28 at 63 days after treatment compared to CK,but those of Zhengmai9023 and Huaimai 30 tended to decline,the results suggested that cold plasma treatment had certain timeliness,varying with the cultivars.
