摘  要:
以TM60444和SC9木薯(Manihot esculenta Crantz)组培苗根、茎、叶为材料,采用乙醇∶丙酮溶液萃取方法,利用紫外-可见分光光度计对两种木薯组培苗根、茎、叶中的叶绿素和胡萝卜素含量进行了测定,并对类胡萝卜素生物合成相关基因进行了定量分析。结果表明,两个品种叶绿素和胡萝卜素含量都是叶>茎>根;而类胡萝卜素含量是叶>茎≈根。

摘  要:
Ultraviolet-visible spectrophotometer was used to detect the content of chlorophy Ⅱ and carotenoids in TM60444 and SC9 tissues culture seedings. Meanwhile, the relative genes of carotenoids biosynthesis were analyzed. The results showed that there is nearly no difference between two stains and the contents of chlorophyll and total carotene in two seedings : leaf>stem>root; and the content of carotenoids: leaf>stem, while the stem is approximately the root.
