Figure 1.

g_s (mol m⁻² s⁻¹) during COS response experiments in representative plants from each group reported in Table I, with normalized g_s of f_e < 0.1 (A), f_e < 0.3 (B), and f_e > 0.3 (C). For the variations in f_e in each group, see Table I. Experiments were conducted under light intensity of 1,189 μmol photons m⁻² s⁻¹, atmospheric concentration of CO₂ (approximately 400 μmol mol⁻¹), temperature of approximately 23°C, and RH of approximately 75%. A, Citrus maxima (white squares), Citrus madurensis (black circles), and Quercus robur pedunculiflora (gray squares). B, Crocosmia × crocosmiiflora [aurea × pottsii] (white circles), Diospyros virginiana (black circles), and Cestrum nocturnum (gray squares). C, Eucalyptus camaldulensis (white circles), Antigonon leptopus (black circles), and Diospyros digyna (gray squares).
