| dc.description | The photosynthetic response to CO<sub>2</sub> concentration, light intensity and temperature was investigated in water hyacinth plants (Eichhornia crassipes (Mart.) Solms) grown in summer at ambient CO<sub>2</sub> or at 10000 μmol(CO<sub>2</sub>) mol<sup>−1</sup> and in winter at 6000 μmol(CO<sub>2</sub>) mol<sup>−1</sup> Plants grown and measured at ambient CO<sub>2</sub> had high photosynthetic rate (35 μmo1(CO<sub>2</sub>) m<sup>−2</sup> s<sup>−1</sup>), high saturating photon flux density (1500–2000) μmol m<sup>−2</sup> s<sup>−1</sup> and low sensitivity to temperature in the range 20–40 °C. Maximum photosynthetic rate (63 μmol(CO<sub>2</sub>) m<sup>−2</sup> s<sup>−1</sup>) was reached at an internal CO<sub>2</sub> concentration of 800 μmol mol<sup>−1</sup>. Plants grown at high CO<sub>2</sub> in summer had photosynthetic capacities at ambient CO<sub>2</sub> which were 15% less than for plants grown at ambient CO<sub>2</sub>, but maximum photosynthetic rates were similar. Photosynthesis by plants grown at high CO<sub>2</sub> and high light intensity had typical response curves to internal CO<sub>2</sub> concentration with saturation at high CO<sub>2</sub>, but for plants grown under high CO<sub>2</sub> and low light and plants grown under low CO<sub>2</sub> and high light intensity photosynthetic rates decreased sharply at internal CO<sub>2</sub> concentrations above 1000 μmol<sup>−1</sup>. |
