| 摘 要： | 本文利用60Co-γ射线对芜菁、猪殃殃和反枝苋3种杂草种子进行了50~1000Gy的辐照处理,研究了不同剂量对3种杂草种子萌发的影响,结果表明,发芽7d后,1kGy以下剂量的辐照对3种杂草种子的发芽具有一定的抑制作用,抑制效果因杂草种类的不同而有差异。

| Abstract: | Effect of gamma irradiation on the germination of three weed seeds was studied.Three weed seeds were treated by 50Gy/100Gy/200Gy/400Gy/700Gy and 1000Gy.The results showed that gamma irradiation(<1kGy) could inhibit the germination of three weed seeds,but effect of irradiation on the germination varied with the species. |
