Abstract: The photosynthesis, chlorophyll content and the growth traits of the clone tea seedling grown under different light conditions (8%, 15%, 35%, 42%, 50% and 75% ambient light) under the greenhouse were compared. The photosynthetic rate (Pn), maximum photosynthetic rate (Pnmax), apparent quantum yield (AQY) and new biomass reached their maximum values at 75% ambient light condition. The content of chlorophyll, death rate, specific leaf area (SLA) and leaf area ratio (LAR) decreased with the increase of light intensity, while the ratio of chlorophyll a/b, root emerging rate of the plant, traumatic tissue formation rate, root shoot ratio (R/S) and root mass ratio (RMR) increased as the light intensity increased. 50% and 75% ambient light were beneficial for the fast seedling-breeding to increase the light transmissivity of the green house and improve the light intensity for the seedling in the tents during cloudy days.
