In order to discover light quality's effects on growth, photosynthesis and effective components content of Panax notoginseng, a pot experiment using 7 light qualities (red, orange, yellow, green, cyan, violet, and blue) was conducted. The growth, photosynthesis and content change of effective components were measured during plant growth. The results showed that light qualities had significant effect on plant growth, red light increased the plant height, while cyan, yellow, violet, and blue lights promoted accumulation of biomass underground, blue and yellow lights increased the photosynthesis, cyan light increased accumulation of ginsenoside Rd, yellow and cyan lights increased total effective components of individual plant.
