We considered Betula platyphylla var. japonica and Betula maximowicziana as pioneer species, Quercus mongolica var. crispula as a mid\uffe2\uff80\uff90successional species, and Acer mono as a climax species. The plants were grown under shade conditions (10% of full sunlight) in a CO2\uffe2\uff80\uff90regulated phytotron. Light compensation points (LCPs) decreased in all tree species when grown under elevated CO2 (720\uffc2\uffa0\uffce\uffbcmol\uffc2\uffb7mol\uffe2\uff88\uff921), which were accompanied by higher apparent quantum yields but no photosynthetic down\uffe2\uff80\uff90regulation. LCPs in Q.\uffc2\uffa0mongolica and A.\uffc2\uffa0mono grown under elevated CO2 were lower than those in the two pioneer birch species. The LCP in Q.\uffc2\uffa0mongolica seedlings was not different from that of A.\uffc2\uffa0mono in each CO2 treatment. However, lower dark respiration rates were observed in A.\uffc2\uffa0mono than in Q.\uffc2\uffa0mongolica, suggesting higher shade tolerance in A.\uffc2\uffa0mono as a climax species in relation to carbon loss at night. Thus, elevated CO2 may have enhanced shade tolerance by lowering LCPs in all species, but the ranking of shade tolerance related to successional traits did not change among species under elevated CO2, i.e. the highest shade tolerance was observed in the climax species (A.\uffc2\uffa0mono), followed by a gap\uffe2\uff80\uff90dependent species (Q.\uffc2\uffa0mongolica), while lower shade tolerance was observed in the pioneer species (B.\uffc2\uffa0platyphylla and B.\uffc2\uffa0maximowicziana).</p>", "keywords": ["0106 biological sciences", "CO2 enrichment", "photosynthesis", "Acclimatization", "Acer", "Carbon Dioxide", "15.
