Environment without light sources was taken as the control group. The results showed that different light sources and different distances from light sources to plants had diversified impact on the photosynthetic physiology of Picea koraiensis. Among these different color lights, green light had the least influence on Picea koraiensis, yellow light and purple light had greater influence.展开更多
