茶树的叶片是为茶树生长、发育提供同化产物和能量的主要器官,为整个植株的代谢源。但是,叶片的生长从芽原茎分化、芽的形成、萌发以及幼叶的生长,这一活动过程中所需要的同化物还需由成熟叶成其它营养器官中输入。这个输入过程,从代谢的角度来分析又是代谢库。只有当叶片完成上述的生长过程后,才逐渐地转为同化产物的输出,转化为代谢源。所以,茶树叶片的生长过程存在着同化产物的代谢库与代谢源的变化过程。同样,作为叶片着 Tea tree leaves for the tea tree growth and development to provide assimilation products and energy of the main organs for the entire plant metabolism. However, the growth of the leaves from the buds of the original stem differentiation, bud formation, germination and growth of young leaves, the activities needed during this event need to mature leaves into other vegetative organs into. This input process, from the metabolic point of view is the metabolic library. Only when the leaves have completed the above-mentioned growth process are they gradually converted to the output of assimilation products and converted into metabolic sources. Therefore, the process of growth of tea leaves there is the assimilation product metabolism and metabolism of the source of change. Similarly, as a blade
