摘要
研究大气压条件下空气环境中氩气放电冷等离子体射流处理对芥菜种子发芽率及幼苗根长的影响。比较了不同的放电电压和不同的处理时间下芥菜种子的发芽率及根长。结果表明,与对照组比较,在放电电压1.6kV、处理时间120s和30s的条件下,等离子体射流处理对种子的生长起到了促进作用;在放电电压2.2kV、处理时间120s及放电电压2.8kV的条件下,等离子体射流处理对种子的生长发育起到了抑制作用。
The effect of atmospheric pressure plasma jet treatment on seed germination rate and roots length of mustard was studied. Seed germination rates and root lengths of mustard seeds treated by plasma jet with different voltage and different time were compared with reference groups. The results show that seed growth is certainly promoted by plasma jet treatment with the discharge voltage of 1.6 kV and processing time of 120 s and30 s, while seed growth is significantly inhibited by treatment with 2.2 kV and 120 s or the discharge voltage of2.8 kV.
