| 中文摘要 | Little is known about the response of trees to elevated ozone (O(3)) in the subtropical region of China, where ambient O(3) concentrations are high enough to damage plants. In this study, pigment content, gas exchange and chlorophyll (Chl) a fluorescence in leaves of Liriodendron chinense (Hemsl.) Sarg seedlings, a deciduous broadleaf tree species native in subtropical regions, were investigated at 15, 40, and 58 days after O(3) fumigation (DAF) at a concentration of 150 mm(3) m(-3) (E-O(3)). At the end of experiment, seedlings were harvested for biomass measurement. E-O(3) caused visible injuries on the mature leaves e. g. necrotic patches and accelerated early defoliation. Relative to the charcoal-filtered air (CF) treatment, E-O(3) significantly decreased shoot and root biomass, pigment content, light-saturated net photosynthesis (P(Nsat)), stomatal conductance (g(s)), maximum rate of carboxylation (V(cmax)), photochemical quenching coefficient (q(p)) and effective quantum yield of PSII photochemistry (Phi(PSII)), and also caused a slight reduction in relative increase of basal diameter. Therefore, L. chinense can be assumed to be an O(3)-sensitive tree species, which will be threatened by increasing ambient O(3) concentrations in China. |
