激光辐照多年生黑麦草种子的生物学效应初探

Effect of HeNe laser radiation on Lolium perenne seed vitality

通过对不同剂量He-Ne激光辐照多年生黑麦草(守门员)种子产生的生物学效应,结果分析表明,低剂量的He-Ne激光辐照能显著地提高多年生黑麦草种子活力,而高剂量有明显地抑制种子活力的作用,He-Ne激光辐照亦可提高多年生黑麦草越夏能力和抗旱能力即抗逆性。

The biological effect of different dosage HeNe laser (λ=632.8 nm,W=15 mW) of irradiating the Lolium perenne seed has shown that low dosage of irradiation could improve the seed vitality and droughtresistant ability, but high dosage could suppress. HeNe laser irradiation could improve the resistance.
