21种豆科牧草辐射敏感性及适宜辐射剂量的研究

A STUDY ON RADIATION——SENSITIVITY OF TWENTY SPECIES OF FORAGE LEGUMES AND THE OPTIMUM DOSE FOR THEM

以不同剂量的^(60)Co—γ射线照射7个属的21种豆科牧草种子,结果显著地抑制了幼根的生长,并降低了其活力。按多靶单击模型 Y=1—(1—e(?))~n 拟合效应曲线,经电子计算机处理求出了21种牧草种子的适宜辐射剂量。

After treated with the ray of^(60)Co-γ,the growth of young roots of twenty legume species was obviously inhibited.And the vigour of young roots was reduced.A“multitarget-single hit- ting”model,Y=1-(1-e^(-?))~n,was used to predict the application rate——effect curve.Anal- ysis of the data by computer gives us the rational radiation dose for all the treated legumes.
