茶树叶内嘌呤碱类、儿茶素类、游离氨基酸类等化学成分的代谢特点已有较多的研究,而有关这几类化学成分在花内的代澍还缺乏研究。一般认为,花器比营养器官更为保守,因此,研究花器内物质的代谢特点有望为研究茶树体内物质代谢的规律及依据化学证据进行茶树的分类、研究茶树的起源等提供新的资 There have been more studies on the metabolic characteristics of the chemical constituents such as purine bases, catechins and free amino acids in tea leaves. However, there is a lack of research on the generation of these chemical constituents in flowers. It is generally believed that floral organs are more conserved than vegetative organs. Therefore, it is expected that the study on the metabolic characteristics of floral materials will provide new funding for studying the laws of material metabolism in tea plants and the classification of tea trees based on chemical evidence and for studying the origin of tea trees
