用Ｃｏ(６０)辐射豇豆种子，随剂量的增加，种子的发芽率降低，发芽后的死亡率增加；剂量为２１０００ｒａｄ、１３０００ｒａｄ时将导致有丝分裂不正常和形态变异，尤其是前者，变异显著，而剂量为４０００ｒａｄ未见到明显变异。
The radiation of cowpea seeds with Co (60) increased the seed germination rate and increased the mortality after germination. The doses of 21000rad and 13000rad resulted in mitotic abnormalities and morphological changes, especially the former with significant variation The dose of 4000rad did not see significant variation.
