Fig. 5.

Simulation of the temporal response of a, g_s, A and W_i with different alterations on SD, k_i, and α_L under a step change of light from 100 (shaded area) to 1000 (white area) μmol m⁻² s⁻¹. a-d Impact of a variation of the stomatal density (SD) from 400 (black line) to 200 mm⁻² (red dashed line). e-h Impact of a variation of the time constant for stomatal aperture (k_i) from 1430 (black line) to 2860s (red line). i-l Impact of a variation of the slope of the relationship between the pore area and the light (α_L) from 0.77 (black line) to 0.38 μm²/μmolm⁻²s⁻¹(red line). The dotted lines on (b, f, j) represent the rates of g_s variation for the first 10 min of the step change estimated by linear regression.
