Analysis of stomatal density, stomatal (guard cell) area, length, and widthThe table shows measurements of stomatal distribution and stomatal area, length, and width in the form of ‘mean±SD’ for n=40. An unpaired t-test was performed for statistics: * significant at the P <0.05 level; ** significant at the P <0.01 level; *** significant at the P <0.001 level.
