摘　　要：利用不同电流强度和处理次数组合的等离子体技术处理辣椒(Capsicum annuum L.)种子,进行发芽和育苗试验。结果表明,适宜电流强度和处理次数组合的处理B(电流强度为1A、处理次数为3次)与处理C(电流强度为2A、处理次数为1次)对辣椒种子的萌发和幼苗生长有促进作用;电流强度弱或处理次数少组合的等离子体技术处理辣椒种子,其促进作用不明显;而用电流强度强或处理次数多组合的等离子体技术处理辣椒种子,对辣椒种子的萌发和幼苗生长又有抑制作用。综合各项指标,处理B和处理C对辣椒种子的发芽势、发芽率、种子活力指数及辣椒幼苗的壮苗指数等各项指标均有不同程度地增加,是适宜的电流强度和处理次数组合。Germination and seedling test was conducted using different combinations of electric current intensity and treatment times to treat Capsicum annuum L.seeds.The results showed that treatment B（1 A of current intensity and 3 treatment times） and treatment C（2 A of current intensity and 1 treatment time）,the suitable combination of electric current intensity and treatment times,had the effect of promoting seeds germination and seedlings growth.The promotion effect of plasma to seeds germination and seedlings growth when treated with lower current intensity and fewer treatment times was not obvious.But the plasma had inhibition on the seeds germination and seedlings growth when treated with stronger current intensity and more treatment times.Treatment B and treatment C were the most suitable combinations according to the test of germination potential,germination rate,vigor index of C.annuum seeds,the healthy index of seedlings and so on.
