摘要
N^+离子束辐照水稻种子表面,经扫描电镜放大2000倍观察。均发现与对照(未经照射)具有不同的表面观及剖面结构,说明N^+离子束对种子有一定的影响。
Surface of shelled rice seed irradiated by nitrogen cation beam was studied by using SEM at 2000 ×. Both surface and inner struction of the shelled seeds was found to be different from that of untreated seeds, It suggests that nitrogen cation beam has effects on rice seeds.
