^a The primary inflorescence stems of Arabidopsis plants grown until global proliferative arrest stage (Hensel et al., 1994) were used to determine, on the main inflorescence, the number of siliques (containing at least one seed), infertile ovaries, and arrested buds; and seeds in each silique (see also Fig. 5C). ^b Average seed number per silique was determined as the total number of seeds on the main inflorescence divided by the number of siliques. ^c Average seed weight was calculated using 50 seeds from each plant. Values are means ± SE. Different superscript symbols (*, †) indicate statistically significant differences between lines, assessed by one-way ANOVA with Tukey-Kramer multiple comparison tests at P < 0.05.
