Fig. 4From: Elevated CO2 concentration induces photosynthetic down-regulation with changes in leaf structure, non-structural carbohydrates and nitrogen content of soybeanThe spatial distribution pattern of stomata on the adaxial surface (a) and abaxial surface (b) of soybean leaves under elevated CO2 concentrations. The upper and lower 95% boundaries were obtained by Monte Carlo simulation of 100 replicatesBack to article page
