Abstract:
Potted seedlings of Pinus koraiensis, Picea koraiensis, and Larix olgensis, the dominant coniferous tree species in Changbai Mountain, were grown under elevated CO2 concentration (700 mumol.mol-1) and ambient CO2 concentration (400 mumol.mol-1) for two year, and their photosynthesis light response curves were determined with CI-301PS CO2 gas analysis system under a series of light intensity from 0 to 2500 mumol.quanta.m-2.s-1. The comparison of dark respiration rate (DRR), maximum net photosynthetic rate (Amax), quantum use efficiency (QUE), light compensation point (LCP), light saturation point (LSP) and photo inhibition point (PP) for the seedlings of these coniferous tree species under different CO2 concentration showed that Larix olgensis, which had better adaptation of photosynthesis to elevated CO2 concentration, was heliophilous species. The shade-tolerant species Picea koraiensis showed the least adaptation of photosynthesis to elevated CO2 concentration. Furthermore, the relationship between photosynthetic physiological character of tree species and their succession status was also discussed in this paper.
