Photosynthetic responses of sunflower plants grown for 52 d in ambient and elevated CO2 (A=350 or E=700 μmol mol-1, respectively) and subjected to no (control), mild or severe water deficits after 45 d were analysed to determine if E modifies responses to water deficiency. Relative water content, le...
