研究了氮离子注入与叠氮化钠处理水稻种子的诱变效应。结果表明：氮离子注入与叠氮化钠处理相比，Ｍ＿１代生理损伤轻，诱发的Ｍ＿２代株高突变频率较高，而叶绿素缺失和抽穗期突变频率则较低。以诱变效率来比较，氮离子注入对叶绿素缺失突变的诱变效率低于叠氮化钠处理，而对株高和抽穗期突变的诱变效率则高于叠氮化钠处理。上述研究结果说明氮离子注入可以作为一种新的诱变技术用于水稻品种改良实践。
The mutagenic effects of nitrogen ion implantation and sodium azide treatment of rice seeds were studied. The results showed that compared with the sodium azide treatment, the physiological damage of M_1 generation was more obvious than that of sodium azide treatment. The frequency of high mutation of M_2 generation plants was higher than that of sodium azide treatment, while the frequency of chlorophyll deletion and heading stage mutation was lower. Compared with the mutagenic efficiency, the mutagenic efficiency of nitrogen ion implantation for chlorophyll deletion mutation was lower than that of sodium azide treatment, but the mutation efficiency for plant height and heading date was higher than sodium azide treatment. The above results show that nitrogen ion implantation can be used as a new mutagenesis technique for rice variety improvement.
