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.
