- 摘要:
- 以“金球”、“玉粒”2个黄皮洋葱品种为试材，采用CO2和He-Ne 2种激光的3种剂量，分别辐照2个黄皮洋葱的湿种子，研究了辐照对其L1代净同化率、蛋白质含量、叶总糖含量、鳞茎总糖含量等4个生理生化指标的影响。结果表明：CO2激光辐照黄皮洋葱的蛋白质含量、净同化率、叶总糖含量、鳞茎总糖含量的变异小于He-Ne激光辐照；使用He-Ne激光辐照黄皮洋葱种子容易从其变异后代中选择出优良变异株，该研究结果可为洋葱激光诱变育种提供参考。
- Abstract:
- Taking two yellow onion varieties of ‘Jinqiu’ and ‘Yuli’as materials,wet seeds of yellow onion were treated by He-Ne laser and CO2 laser at three dosage levels respectively.The physiology effects of yellow onion L1 generation caused by various treatments were observed in net assimilate rate,protein content,sugar content of leaf,sugar content of stem.The results showed that,variability of protein content,sugar content of leaf,sugar content of stem,net assimilate rate in onion generation induced mutation by He-Ne laser was larger than induced mutation by CO2 laser.It was a good method for select the excellent breed under He-Ne laser irradiation on yellow onion,and could provide reference for practice and promotion of the laser mutation onion breeding method.
