Relationships between net photosynthesis A and mesophyll conductance gm (A–E) and between stomatal conductance gs and gm (F–J) under drought and control conditions. Data are derived from the light curve experiments for each species at 400 ppm CO2. Open circles: well watered, black circles: dry conditions. Solid lines represent the regression lines for the well watered treatments, dotted lines are the regressions for the drought treatments, data shown are mean values (herbaceous species n = 5, trees n =10) ± standard deviation.
ppl12160-sup-0002-FigureS2.docWord document70KFig. S2. Sensitivity analysis for the calculation of gm for Impatiens noli tangere. The figure shows the sensitivity of gm for a deviation (in %) of the measured values of Ci, ETR and A and for a variation (in %) of the estimated values of Γ* for the plants from the control (solid lines) and the drought treatment (dotted line). The sensitivity analysis was performed for gm at Amax.
