在茶树细胞固体培养研究的基础上，系统分析了培养基大量元素、微量元素和有机物质等对茶树悬浮培养细胞儿茶素产生的影响。根据试验结果，设计了儿茶素生产培养基，使茶悬浮细胞儿茶素总量提高至于重的３０％左右。改良培养基上茶树悬浮培养细胞的儿茶素形成高峰期在２０一２５ｄ间。 Based on the study of cell solid culture in tea plant, the effects of medium elements, trace elements and organic substances on the catechin production in tea plant cells were systematically analyzed. According to the test results, the catechin production medium was designed to raise the total amount of catechins in tea suspension cells to about 30% by weight. On the modified medium, the peak of catechin formation in the suspension cultured cells was between 20 days and 25 days.
