冬小麦经电子束、中子和γ射线辐照后,均产生生物效应。电子束对中子和γ射线的相对生物效应(RBE)值均小于1,中子对γ射线的RBE值远远大于1。这说明电子束的M_1生物效应远远小于中子的M_1生物效应而与γ射线的M_1生物效应相近。对于电子束辐照,M_1的半致死剂量范围是185～370Gy,更靠近370Gy,致死剂量是740～925Gy。对于M_2的诱变效率,电子束>中子>γ射线。电子束辐照可以扩大突变谱,提高诱变效率,最佳诱变剂量范围是370～555Gy,中子比γ射线诱变效率高,较适宜的辐照剂量为25Gy。当M_1生物损伤稍大于50%时,用电子束进行辐照,M_2代的诱变频率较高。
Winter wheat by electron beam, neutron and γ-ray irradiation, have a biological effect. The relative biological effects (RBE) of electron beam on neutron and γ-ray are all less than 1, and the RBE value of neutron to γ-ray is far greater than 1. This shows that the electron beam M_1 biological effect is much smaller than the neutron M_1 biological effect and the γ ray M_1 biological effect is similar. For electron beam irradiation, the semi-lethal dose range of M 1 is 185-370Gy, closer to 370Gy and the lethal dose is 740-925Gy. For M_2 mutagenesis efficiency, electron beam> neutron> gamma rays. Electron beam irradiation can broaden the mutation spectrum and improve the mutagenesis efficiency. The optimum mutagenesis dose range is 370-555Gy, and the neutron gamma mutagenesis efficiency is higher, and the more suitable irradiation dose is 25Gy. When the biological damage of M_1 was slightly larger than 50%, the irradiation with electron beam had a higher frequency of M_2 generation mutagenesis.
