Figure 2. Effects of defoliation and plant category on the number and size of seeds.

(A) log (number of seeds) and (B) log (mean seed mass [mg]) of Arabidopsis thaliana (least-square means ± S.E.). Different letters indicate statistically significant differences in means based on Tukey's HSD test performed separately by plant category (vegetative rosette defoliated early in the season, bolting plant defoliated early in the season, or flowering plant defoliated a month later).
