Table III. Stomatal pore measurements.
Mean stomatal measurements D, P, and I (see Fig. 7A) were used to calculate the maximum theoretical rate of gmax and gcmax in the wild type and three independent transgenic lines. Values represent means ± se of stomatal measurements taken from the middle of the penultimate leaf of the first tiller. Asterisks indicate significant differences from the wild type as determined by a one-way ANOVA test: **, P > 0.01; ***, P > 0.001; and ****, P > 0.0001.
