Impact of stomatal anatomical traits on steady-state gas exchange and stomatal kinetics. (a) Linear regressions between stomatal length (SL) and g sw at 1,000 (white dots), 100 (grey dots) and 0 (black dots) PAR (n = 15). (b) Linear regressions between stomatal density (SD) and g sw at 1,000 (white dots), 100 (grey dots) and 0 (black dots) PAR (n = 15). (c) Linear regressions between SL and A at 1,000 (white dots) and 100 PAR (grey dots). (d) Linear regression between SD and A at 1,000 (white dots) and 100 PAR (grey dots). (e) Linear regressions between SL and iWUE at 1,000 PAR (white dots) and 100 PAR (grey dots) (n = 15). (f) Linear regressions between SD and iWUE at 1,000 PAR (white dots) and 100 PAR (grey dots) (n = 15). (g) Linear regressions between SL and half-time (T 50%) of the light transitions 1,000–100 (grey dots), 100–1,000 (white dots) and 1,000–0 (black dots) PAR (n = 15). (h) Linear regressions between SD and T 50% of the light transitions 1,000–100 (grey dots), 100–1,000 (white dots) and 1,000–0 (black dots) PAR (n = 15). R 2 and p values are indicated. Dashed lines indicate statistically non-significant linear regressions (p > 0.05).
