Figure 1.

Theoretical temporal response of stomatal conductance (g _s; black) and net CO₂ assimilation (A; red) to a step change in PPFD from 100 (shaded area) to 1000 (unshaded area) μmol m⁻² s⁻¹. Where Sl _max describes the maximum temporal response of g _s (dashed line), λ describes the time‐lag before g _s starts to increase (blue arrow) and G _smax describes the steady‐state target of g _s under 1000 μmol m⁻² s⁻¹ PPFD. The dotted lines represented the time and the value were 95% A is reached.
