The experiment was conducted to examine the effects of shading (full sunlight, 60%, 40%, 20% and 5% of sunlight) on pigment content and chlorophyll fluorescence characteristics of Cyclobalanopsis glauca container seedlings. The results showed that the ratios of Chla/Chlb and Car/Chi increased by 3.00-3.38 and 0.131-0.162, but the contents of Chla, Chlb and Car, decreased by 3.68 mg·g^-1-1.58 mg·g^-1, 1.23 mg·g^-1-0.47 mg·g^-1 and 0.64 mg·g^-1-0.33 mg·g^-1 with the increase of light intensity. Quantum efficiency of electron transport (ΦPSII) and photochemical quenching (qP) in leaves of C. glauca significantly increased by 0.131-0.701 and 0.925-0.238, but non-photochemical quenching (qN) decreased by 2.54 to 0.16 in the more shading conditions. As a result, C. glauca, as the hi-positive light species, had a strong shade tolerance.
