EMS诱变玉米突变体苗期生理生化特性研究

实验分别选取四种白色突变玉米白1、白2、白3、白4为材料，以诱变的非突变玉米为对照。分析了玉米的代谢特性和抗性。结果表明突变体的代谢及抗性没有非突变体强，但我们也发现，在四种白色突变体中，白2表现突出。白2幼苗根系活力，叶绿素含量，POD、SOD活性，脯氨酸含量均比对照高，而加MDA含量比对照低，说明在四种突变体玉米中白2苗期表现出对环境的适应能力提高，且抗性增强。

Research on Seeding Physiology and Biology Characters of Maize Mutations Induced by EMS

This article analyzed maize physiological metabolism and resistance characters.Mutation maize material white1,white2, white 3,white4 and non-mutation maize that induced by EMS were used.The result showed that non-mutation maize have better properties than mutation maize in physiological metabolism and resistance characters.But we also found that white2 showed higher level than non-mutation maize in the root system livingness,the content of chlorophyll in leaves,activity of POD and SOD also the content of proline,The content of MDA lower than non-mutation maize.Of all the four maize materials,white 2 presents stronger ability of acclimatization and better resistance character.
