Responses of Growth, Photosynthesis and VOC Emissions of Pinus tabulaeformis Carr. Exposure to Elevated CO 2 and/or Elevated O 3 in an Urban Area

Responses of growth, photosynthesis and emission of volatile organic compounds of Pinus tabulaeformis exposed to elevated CO 2 (700 ppm) and O 3 (80 ppb) were studied in open top chambers. Elevated CO 2 increased growth, but it did not significantly ( p  > 0.05) affect net photosynthetic rate, stoma... Full description

Elevated CO 2 increased growth, but it did not significantly ( p  > 0.05) affect net photosynthetic rate, stomatal conductance, chlorophyll content, the maximum quantum yield of photosystem II, or the effective quantum yield of photosystem II electron transport after 90 d of gas exposure. Elevated O 3 decreased growth (by 42.2% in needle weight and 25.8% in plant height), net photosynthetic rate and stomatal conductance after 90 d of exposure, but its negative effects were alleviated by elevated CO 2 .
