Other claims from this paper (8)
- Observation Water hyacinth grown and measured at ambient CO2 had a high photosynthetic rate (35 μmol CO2 m-2 s-1).
- Observation Plants grown and measured at ambient CO2 had a high saturating photon flux density of 1500-2000 μmol m-2 s-1.
- Observation Plants grown and measured at ambient CO2 had low sensitivity to temperature in the range 20-40 °C.
- Observation Maximum photosynthetic rate (63 μmol CO2 m-2 s-1) was reached at an internal CO2 concentration of 800 μmol mol-1.
- Intervention effect Plants grown at high CO2 in summer had photosynthetic capacities at ambient CO2 that were 15% less than plants grown at ambient CO2.
- Intervention effect Maximum photosynthetic rates were similar between plants grown at high CO2 and at ambient CO2.
- Observation Photosynthesis of plants grown at high CO2 and high light intensity had typical response curves to internal CO2 concentration with saturation at high CO2.
- Observation For plants grown under low CO2 and high light intensity, photosynthetic rates decreased sharply at internal CO2 concentrations above 1000 μmol-1.
