Comments The effect of growth at elevated concentrations of CO2 on stomatal density and stomatal index (the fraction of epidermal cells that are stomata) is one of the most intensively studied environmental controls on stomatal development. CO2 enrichment changes the stomatal density of different species and different accessions (ecotypes) of Arabidopsis thaliana (Fig. 3b and primary ref). With stomatal densities ranging from 45 to 720mm^2 the mean response is an 11% reduction in density with a doubling of the CO2 concentration (Fig. 3b), and which is insensitive to the basal stomatal density.
