用不同剂量的He—Ne激光和均强电场对水稻种子进行辐照、激发,并且选取不同的辐照时间,在实验室条件下进行萌芽培养实验,结果表明,经过He—Ne激光和适量均强电场辐射的水稻种子可有效的提高发芽率。探讨了影响发芽率的几种因素,并对激光和均强电场诱变的机理和生物学效应作了讨论。 Irradiation and excitation of rice seeds with different doses of He-Ne laser and a strong electric field were conducted, and different irradiation time were selected to conduct germination culture experiments under laboratory conditions. The results showed that after He-Ne laser and appropriate amount of average Strong electric field radiation of rice seeds can effectively improve the germination rate. Several factors influencing germination rate were discussed, and the mechanism and biological effects of mutagenesis by laser and electric field were discussed.
