摘　　要：Phytochemicals（including proteins, lipids, carbohydrates, vitamins, minerals,phenolic compounds and so on） are one of the most important groups of the bioactive compounds in vegetables and fruits, benefit for human health. The phytochemicals biosynthesis is affected by environmental factors, and light in particular. Light effects can be categorized in photoperiod, intensity and quality. While it is widely known that light intensity can positively affect phytochemicals accumulation, the effects of light quality are more complex and often reported with mixed results. So this review focuses on the currently knowledge about different light quality on the control of phytochemicals biosynthesis. A better knowledge on these regulatory mechanisms will be useful for modifying phytochemicals biosynthesis in vegetables and fruits.植物化学物是蔬菜和水果所含有的一类重要营养成分,包括蛋白、脂类、碳水化合物、维生素及多酚等物质,其对人类健康起重要作用。这类营养物质在蔬菜和水果中的合成受环境因素的调控,其中,光照起着重要的作用。光通过光周期、光强及光质来影响这些植物化学物质的合成。众所周知,光强能影响植物体化学物的合成,但是特定的光谱(光质)对其合成的作用则比较复杂,并且不同作物和物种的响应也不同。因此,本文主要介绍了光质对蔬菜及水果中化学物合成的影响,及其可能的调控机制,以期为人工调控植物体营养成分的合成提供理论依据。
