Abstract:

Light is the most significant factor in the regulation of plant growth. With the widespread use of lighting technique in plant flow line production and nursery stock production, the effects of plant lighting and the use of artificial lighting technique for promoting plant growth have been studied constantly and gradually. Accordingly, the present article reviews the effects of light (e.g., intensity, quality and photoperiod) on plants. Light intensity, for example, affects the photosynthetic and growth rates of plants, whereas light quality affects seed germination, morphogenesis, and photosynthesis, and photoperiod affects morphogenesis and photosynthesis. The article also reviews recent progress in artificial lighting methods and strategies, such as the reduction of light waste and the development of dynamic lighting that promotes plant growth, and current trends in the development of lighting technique. That is to take light source, mechanism of light, and multi-factor influence to plant as research focus.

Key words: plant growth, light intensity, photoperiod, lighting technology, blue-red lighting
