摘要
不同弱光条件下对番茄叶色突变体06883的形态指标、叶绿素含量、可溶性蛋白和可溶性糖含量、保护酶活性、丙二醛(MDA)含量进行研究。结果表明:弱光条件下,番茄叶色突变体06883的比叶干样质量(SLM)、比叶鲜样质量(VLM)、叶绿素含量、保护酶活性的减少值以及株高/茎粗、叶面积比(LAR)、MDA含量的增加值都小于其野生型06884,所以番茄叶色突变体06883对弱光敏感度小于其野生型06884,具有一定耐弱光性,是良好的耐弱光种质资源。
The morphological indexes,contents of chlorophyll,soluble protein,soluble sugar and MDA,and activities of several protective enzymes of tomato（Lycopersicon exculentum Mill.）leaf color mutant 06883 treated by different levels of weak light stress were measured in this research.The results show that,under different levels of weak light stress,the decrease value of SLM,VLM,chlorophyll content,activities of protective enzymes and the increase value of plant height/stem diameter,LAR,MDA content of tomato leaf color mutant 06883 are less than that of its wild-type 06884.Therefore,the sensitivity to weak light stress of leaf color mutant 06883 is less than that of its wild-type 06884.It is,to certain extent,tolerant to weak light and could be used as good germplasm resource tolerant to weak light.
