Abstract:

Photosynthesis is the basis of ginseng dry matter produced and it has an important effect of ginseng on yield and quality. This paper reviewed the photosynthetic characteristics of ginseng, summarized the photosynthetic characteristics of diurnal variation and the variation of different growth stages of ginseng, analyzed the factors affecting photosynthesis, including light intensity, light quality, temperature, CO2, source-sink correlation, light spot influence the photosynthetic characteristics of ginseng. The problems were pointed out, for example the photosynthetic characteristics of ginseng were not given too much emphasis, and only one single factor was emphasized on the influence of the photosynthetic characteristics of ginseng. The future research was provided.
