Different CO₂ air concentration effects on the rate of stomatal opening (k_o)

	Younger plants
CO₂ air concentration (μmol CO₂ mol⁻¹)	400	400 to 300	400 to 500
Parameter (% s⁻¹)	k_c	k_o	k_c
Mean value	0.29	0.06	0.46
SD	0.04	0.01	0.03

CO₂ concentration changes were performed when the blueless PAR effect on stomatal conductance was maximal (B–). k_c and k_o values were calculated after fitting of two non linear functions (cf. statistical analysis). n=2 for each treatment (300 and 500 μmol CO₂ mol^-1).
