Abstract: Light is an important energy source and information source for plant growth and development. Light quality as key trigerring factor in the light environment can regulate the whole life cycles of plants by light receptor signaling pathways. The control technology of light quality has been applied gradually to production process of vegetable crops, along with the studies on photobiology and constant R & D on artificial light source with low cost and high efficiency. This paper reviewed the research progress on light quality in regulating plant photosynthesis, mechanism of constructing photomorphogenesis, and application in vegetables production. The papper also introduced in detail the regulating mechanism of light quality during plants growth process, its effects on sprouts, green leafy vegetables, solanaceous fruit vegetables and edible fungi, etc. and how studies on light quality improve economic benefits of vegetables production. The paper elaborated combination schemes of light quality for different kinds of vegetables under artificial light environments, and put forward suggestions for further studying the function of light quality in each growth phase, and carrying out experiments on combining light intensity and photoperiod, so as to optimize specific light recipes for different kinds of vegetables.

摘要： 光是植物生长发育的重要能量源和信息源，光质则作为光环境中的关键影响因子通过光受体传导途径调节植物的整个生命周期。随着光生物学研究的不断深入和低成本高光效的人工光源的不断研发，光质调控技术已逐渐运用到蔬菜作物的生产过程。从光质调控植物光合作用和光形态建成的机理、及其在蔬菜生产中的应用等方面综述了光质对蔬菜作物生长和形态调控方面的研究进展。较详细介绍了光质对植物生长过程的调控机理，在芽苗菜、绿叶类蔬菜、茄果类蔬菜和食用菌类等作物的影响的研究成果，以及光质研究提高了蔬菜生产的经济效益。阐述了人工光环境下蔬菜作物栽培可供参考的光质配制方案，并提出仍需进一步研究光质对蔬菜各生育期的作用及综合光强和光周期进行试验，以期完善不同蔬菜作物光配方。
