Leaf gas exchange of S. capitata performed at 44th (left column) and 66th DOE (right column) under different levels of [CO₂] and temperature. (A,B) Stomatal conductance (g_s). (C,D) Transpiration rate (E). (E,F) Net photosynthesis rate (A). (G,H) Instantaneous water-use efficiency (WUE). [CO₂] levels: ambient (aCO₂) and elevated (eCO₂, 600 μmol mol^-1). Temperature levels: ambient (aT) and elevated (eT, +2°C above ambient canopy temperature). DOE = day of experiment. ANOVA p-values are shown for main effects (CO₂ or T) or interactions CO₂ × T. Stack bars indicate the standard error.
