Figure 6.

The mean proportion of side branches/main branch mass for Arabidopsis thaliana under growth room conditions (20°C, 8 hr of incandescent light) on the University of Maryland College Park campus. Means are presented in rank order for the premutation founder and 20 mutant lines generated from ethylmethane sulfonate (20 μmol/L) mutagenesis (mutant line mean sample size n = 12.40, σ of sample size = 2.89; founder n = 7). Plants without side branches were given a side branch mass of 0. There was no significant effect of mutant line on the trait (p = .31). The premutation founder is circled. Error bars indicate one standard error from the mean
