From: Elevated CO2 concentration induces photosynthetic down-regulation with changes in leaf structure, non-structural carbohydrates and nitrogen content of soybean

Fig. 1

Effects of elevated CO2 concentrations on (a) leaf net photosynthesis rate (An), (b) stomatal conductance (Gs), (c) intercellular CO2 concentration (Ci), and (d) dark respiration rate (Rd). Parameters are measured at ambient or elevated CO2 of their growing condition for each treatment and values given are mean ± standard deviation for n = 5 leaves. The arrow indicates the optimal CO2 concentration for leaf Rd of soybean plants
