| 摘 要： | 对万寿菊种子进行5个剂量的60Co-γ射线处理.结果表明:提高万寿菊发芽率最佳的辐射剂量为80 Gy和160 Gy,而20 Gy和320 Gy辐射处理则抑制了芽和根的生长;但是60Co-γ射线对万寿菊的生长及开花有不同程度的抑制作用,所有剂量的辐射处理幼苗及成苗的高度均低于对照,并且花径也都有所减小.

Effect of 60Co-γ Ray radiation on the Germination Rate and Growth of Tagetes erecta |
| |
| Abstract: | The effect of five different radiation dosages of 60Co-γ ray on the Tagetes erecta was studied. The result showed that 80Gy and 160Gy were suitable for the Tagetes erecta seeds based on the influence of germination rate and the length of bud and root. 20Gy and 320Gy 60Co-γ ray radiation can restrict the germination rate and the growth of bud and root. But 60Co-γ ray radiation restricted the growth and kaihua.The stem height and inflorescence diamet of Tagetes erecta were smaller than comparison. |
