从细胞生长、色素和儿茶素等次生产物组成与含量、苯丙氨酸解氨酶活性以及产物合成动态分析等几方面 ,研究比较了积累色素与不积累色素的两类茶树培养细胞系之间的差异。发现积累色素的细胞系中 ,儿茶素与原花色素的形成能力也得到了大幅度提高 ,且与苯丙氨酸解氨酶活性无关。这一结果表明 ,茶树高产细胞系筛选中 ,可采用细胞色泽为指标 ,使筛选工作得以简化。 From the aspects of cell growth, the composition and content of secondary products such as pigment and catechin, the activity of phenylalanine ammonia-lyase and the kinetic analysis of product synthesis, two types of cultured cell lines with different accumulation of pigments and non-accumulation of pigments difference between. It has been found that in the cell line accumulating pigment, the formation ability of catechins and proanthocyanidins has also been greatly improved, and has nothing to do with the phenylalanine ammonia lyase activity. This result shows that in screening of high-yield cell lines of tea tree, cell color can be used as an indicator to simplify the screening work.
