Fig. 3 — a The relationship between the rate of G_s increase (i.e. speed of stomatal opening) during a dark to light transition and the rate of G_s decrease (i.e. speed of stomatal closure) during a light to dark transition (see Fig. 4a and c for an example of stomatal kinetic responses). b Relationship between the percentage reduction in G_s during a step change in [CO₂] from 400 to 2000 μmol mol⁻¹ and the percentage reduction in G_s as stomatal close during a light to dark transition. Statistical analysis using linear regression. Data presented as in Fig. 1
