摘　　要：绿光是波长为500~599 nm的可见光,一般认为绿色植物对绿光的吸收非常有限,所以之前人们一直忽略绿光对植物的重要意义。近年来绿光对植物的生长作用逐渐得到关注。人们发现绿光不仅能通过其独特的方式被植物吸收,并能参与植物生长的调节。本文将从绿光对光合作用的贡献,以及绿光作为一种信号分子对植物生长的调节,如对植物气孔开启和闭合的调节、光形态建成、生物钟等方面进行阐述,并讨论了植物感知绿光的可能方式或者可能受体。Green light is the visible light with a wavelength of 500–599 nm. It is generally considered that the absorption of green light by green plants is very limited, so the importance of green light has been ignored in plants. In years, more and more attention has been paid to the effect of green light on plant growth. It is found that green light can not only be absorbed by plants through its unique way, but also participates in the regulation of plant growth. In this paper, the contribution of green light to plants are discussed, concluding efficiency of photosynthesis droven by green light, the regulation of green light as a signal molecule to plant growth, such as plant stomatal opening and closing, light morphology, the flowering time and the biological clock. Also, the possible ways of plant perception of green light and the suspected green light receptors are discussed.
