一、激光的生物学效应:He-Ne和CO_2激光可使大豆和棉花苗叶面发皱、叶形变形、颜色发绿、棉苗叶柄加长、叶柄-茎间夹角变小、真叶高于茎尖、红茎率变大。后期子棉、皮棉、衣分增加,而绿豆则花序增多。He-Ne激光抑制小麦乳期苗的生长,Ar~+激光的这种作用则不明显。经He-Ne处理的小麦愈伤组织花药出愈率比CO_2和Ar~+的高三倍。He-Ne,CO_2和Ar~+激光均有改变小麦口松的作用,其效果和材料及激光种类有关。口松特性的改变在L_2代中有遗传。激光处理可改变籽粒的品质。CO_2 First, the biological effects of laser: He-Ne and CO_2 laser bean leaves and cotton seedling folds wrinkled, leaf-shaped deformation, the color of green, cotton seedling petiole lengthened petiole - stem angle between the smaller, true leaf high In the shoot tip, the red stalk rate becomes larger. Late cotton, lint, clothing points increased, while the increase in mungbean inflorescence. He-Ne laser inhibited wheat seedling growth, Ar ~ + laser effect is not obvious. The callus induction rate of HeNe callus was three times higher than those of CO 2 and Ar ~ +. He-Ne, CO_2 and Ar ~ + laser all have the effect of changing the wheat cortex pine, its effect is related to the material and laser type. Changes in the characteristics of ostracoda were inherited in L_2 generation. Laser treatment can change the quality of the grain. CO_2
