Elevated CO/sub 2/ concentration increases stomate numbers in phaseolus vulgaris leaves

Beans were grown under a constant CO/sub 2/ concentration of either 400 or 1200 ..mu..l liter/sup -1/. There was no significant difference in stomate density on the adaxial surface, but there was a significantly lower stomate density on the abaxial surface of leaves in the higher CO/sub 2/ concentration. The leaf area was significantly greater at the higher CO/sub 2/ concentration, and total number of stomates per leaf, calculated from the density and leaf area, was significantly greater for both surfaces of the leaf. We conclude that the observed CO/sub 2/ effect on stomatal density is the result of the large change in leaf area.
