【摘要】 采用 CO2 和 He Ne两种激光的三种剂量 ,分别辐照两个洋葱品种的湿种子 ,采用生理生化的方法 ,从过氧化氢酶、叶绿素、总糖总量等三个方面考查研究洋葱 L1各处理的生物学效应。结果表明 :He Ne激光辐照洋葱 L1代的过氧化氢酶、叶绿素、总糖含量的变异大于 CO2 激光辐照 ,可作为激光诱变洋葱育种参考更多还原

【Abstract】 Wet seeds of onion breeds were trested by HeNe laser and CO 2 laser at three dosage levels separately. A randonied complete block design of three replications was adopted The biological effect was analysed with physiology and biochemistry methods diffence in the physiology effects caused by various trestments were observed in cutalase, chlorophyll and sugar. The variability of catalase, chlorophyll and sugar in onion L 1 generation induced mutation by HeNe laser is larger than induced mutation by CO 2 laser.更多还原
