激光对花生诱变效果的研究

Researches to Induced Changes of Laser to Peanut

Ｈｅ—Ｎｅ、ＹＡＧ和ＣＯ２激光对花生Ｌ１代幼苗期有刺激生长的作用；ＣＯ２激光对花生Ｌ１代的株高有较明显的抑制作用；ＣＯ２、Ｈｅ—Ｎｅ和ＹＡＧ激光对花生Ｌ１代植株的总果数、饱果数有一定的增多作用，且前者最明显，但Ｎ２激光对花生Ｌ１代植株的总果数、饱果数均有明显的减少作用；Ｈｅ—Ｎｅ、ＹＡＧ、Ｎ２和ＣＯ２激光均能诱发药生根尖细胞染色体畸变，且畸变率随辐照剂量的增大而上升；

He-Ne YAG and CO 2 Lasen promated the growing of peanut L 1 generation seedling; CO 2 laser had obviously inhibition to the high of peanut L 1 generation plant;CO 2 He-Ne and YAG Laser might add the numbers of total fruit and plump fruit, the addition to the number of total fruit was more obrious, but N 2 Laser reduced the number of total fruit and plump fruit of peanut L 1 generation plant obviously;He-Ne YAG N 2 and CO 2 Laser all could induce the cell chromosome distortion of pearut root tips, and the rates of distortion increased with the adding amount of radiation; All the indveed charge features by above four kinds of Laser can be passaged inherited.
