冷等离子体处理对水稻种子萌发的影响

摘要

In order to improve the performance of rice seed germination,cold plasma processer with the medium of air and helium (He) in vacuum environment was used respectively to process three kinds of rice seed,Zheyou023,Xiushui134,and Zheyou6326.The powers used in processing were 60 W,70 W,80 W,90 W and 100 W.The germination test was conducted after cold plasma treatment.It turned out that the cold plasma treatment had obvious promoting effects to rice seed germination when the power was 60 W to 100 W.Compared with the untreated group,germination vigor of the above three experimental groups increased by 1.75％ to 13.5％ with the air and helium (He) processing medium,while the percentage germination increased by 1.0％ to 8.75％.The best treatment power of Zheyou023,Xiushui134,Zheyou6326 were 90 W,100 W,80 W in air processing medium,respectively.And when it came to helium (He) medium,Xiushui134,Zheyou6326 were better to be processed at 60W.Zheyou023,however,was not suitable to treat in helium (He) condition.%为提高水稻种子的萌发性能,利用冷等离子体处理机分别以空气、氦气为真空室环境介质,以60、70、80、90和100W的处理功率对浙优023、秀水134和浙优6326 3种水稻种子进行处理,并进行发芽试验.结果表明,在60 ～100W的处理功率范围内,冷等离子体处理对水稻种子的萌发具有明显的促进作用,与未经任何处理的对照组相比,以空气、氦气为处理介质3种水稻种子的发芽势、发芽率分别可提高1.75％ ～13.5％、1.0％～8.75％；以空气为处理介质,浙优023、秀水134、浙优6326水稻种子的较佳冷等离子体处理功率分别为90、100和80 W；以氦气为处理介质,秀水134、浙优6326水稻种子的较佳处理功率为60 W,但浙优023水稻种子不宜以氦气为介质进行冷等离子体处理.
