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.
