中文摘要	4-year-old Pinus koraiensis, planted in open-top chambers at Changbai Mountain Station, received three different treatments [700 mu mol(CO2) mol(-1) = EC, control chamber = CC, and field = F]. Saturated net photosynthetic rate (P-N) was 62 % higher in EC plants compared to CC and F plants as shown by PAR/P-N response curves. Despite the increased PN, EC plants still showed decreased photosynthetic capacity when compared with CC and F plants at the same measurement CO2 concentration. EC plants had the highest stomatal conductance (g(s)) and ratio of intercellular to ambient CO2 concentration (C-i/C-a) compared with CC and F plants when measured at the same CO2 concentration. The C-i/C-a, ratio was a sensitive indicator of stomatal behaviour, but not of photosynthesis. The responses of g(s) to EC did not correlate in magnitude or direction with responses of P-N to EC. There was no significant difference in the number of stomata lines and stomata between EC and C-a.
