植物次生代谢产物在植物生命活动的许多方面均起着重要作用。其种类繁多,目前研究主要集中于萜类、酚类、含氮有机物以及炔类、有机酸等。次生代谢产物的合成和积累受遗传(基因)控制,受树龄、季节(生长发育阶段)的影响,不同种源的同一植物在相同的环境下生长也存在差异,光照强度、光质、温度、水分、养分等环境因子亦会对次生代谢产物的积累产生重要影响。研究这些因素对植物次生代谢产物积累的影响,对为提高其产量而进行的栽培措施具有指导意义,有助于缓解有限的次生代谢物产量与人类越来越大的需求之间的矛盾。

Plant secondary metabolites play an important role in many aspects of plant life activities. There is a great variety of its kind. The present researches mainly focus on terpenoids, phenolics, nitric organic compounds, alkynes, organic acids, etc. The synthesis and accumulation of plant secondary metabolites are not only controlled by genetic, but also infected by the tree-age and seasons (the growth stages of tree). The growth of the same kind of plant that comes from different provenances is different. Light intensity, light quality, temperature, moisture, nutrients and other environmental factors also play a momentous influence on the accumulation of plant secondary metabolites. Studying the influence of these factors to the accumulation of plant secondary metabolites provide a guidance to the cultivation measures to improve their production. At the same time, it will help ease the contradiction between the limited production of plant secondary metabolites and the growing demands by human beings.
