摘　　要：为掌握^(60)Co-γ辐射对红秋葵和黄秋葵的辐射诱变效果,用不同剂量^(60)Co-γ射线(0、20、40、60、80、100、200、300、400、500 Gy)对红秋葵和黄秋葵种子分别进行辐射处理。结果表明,红秋葵的辐射半致死剂量为432. 27Gy;黄秋葵的辐射半致死剂量为717 Gy。辐射剂量低于60 Gy时,可以提高红秋葵和黄秋葵叶片中可溶性糖、可溶性蛋白含量;辐射剂量高于300 Gy时,两种植物中可溶性糖、可溶性蛋白含量会相对降低。In order to determine the radiation induction effects of 60 Co-γray on Hibiscus coccineus and Hibiscus esculentus,the present experiment used different doses of 60 Co-γray(20,40,60,80,100,200,300,400,500 Gy)to radiate the seeds of Hibiscus coccineus and Hibiscus esculentus.The results showed that the median lethal dose of Hibiscus coccineus is 432.27 Gy,while the median lethal dose of Hibiscus esculentus is 717 Gy.The radiation dose lower than 60 Gy could improve the content of soluble sugar and soluble protein content in Hibiscus coccineus and Hibiscus esculentus leaves;when the radiation dose was higher than 300 Gy,the soluble sugar and soluble protein could decrease.
