To test our hypothesis that in the succession process, late-succession species have (l) the highest light-use efficiency (LUE) under low-light environment and (2) the greatest capacity for regulating light-energy utilization and dissipation, we tested tree species which included a pioneer species Pinus massoniana, medium-succession species Schima superba and Castanopsis fissa, and late-succession species Cryptocarya concinna and Acmena acuminatissima, all of which occur in Dinghushan subtropical forest, South China.Under the experimental irradiance gradient (100％, 30％ and 12％ of full sunlight), C.concinna and A.acuminatissima exhibited more effective photosynthetic regulation, and they showed relatively lower photosynthetic capacity (Amax), light compensation point (LCP), light saturation point (LSP), maximum rate of RuBP carboxylation (Vcmax), but a relatively higher apparent quantum yield (AQY).
