Figure 5.

The mean number of trichomes per midrib length (mm) for Arabidopsis thaliana under growth room conditions (20°C, 8 hr of incandescent light) on the University of Maryland College Park campus. Means, in rank order, are presented for the premutation founder and 20 mutant lines generated from ethylmethane sulfonate (20 μmol/L) mutagenesis (mutant line mean sample size n = 10.65, σ of sample size = 3.73; founder n = 7). The effect of mutant line on the trait was not significant after sequential Bonferroni correction (p = .025, α = 0.0125). The premutation founder is circled. Error bars indicate one standard error from the mean
