快中子具有较高的电离密度,是一种强电离辐射。Ehrenberg,L.等认为它的辐射效应比 X 射线高10—100倍,可对遗传物质发生更直接的作用。Mac Key 亦认为中子的辐射效应比 X 射线强,快中子可引起六倍体小麦更多的表型变异。徐成满、赫沃斯托娃都认为快中子对冬小麦的辐射效应比γ射线高40倍。其次中子处理种子时,辐射效应受种子的生理条件、温度、剂量率、辐照后贮存时间等因素的影响较小。此外,一种作物的不同品种对中子的敏感性比较一致。因此中子是一种较好的诱变因素。K.Mikaelsen、李集临、许跃奎等对快中子在水稻、大麦、小麦生长发
Fast neutron ionization has a high density, is a strong ionizing radiation. Ehrenberg, L. et al. Consider it to have a radiant effect 10-100 times more intense than X-rays and have a more direct effect on genetic material. Mac Key also believes that the neutron radiation effect stronger than X-ray, fast neutrons can cause more hexaploid wheat phenotypic variation. Xu Chengman and Hevostova all agree that the fast neutron radiation effect on winter wheat is 40 times higher than that of γ-rays. Secondly, the neutron treatment of seeds, the radiation effects by the seed physiological conditions, temperature, dose rate, storage time after irradiation and other factors. In addition, different varieties of a crop are more sensitive to neutrons. Therefore, neutron is a better mutagen factor. K.
