Probability of Arabidopsis silique-set is position-dependent across flower positions 1–10. Statistically significant interactions were detected between genotype and GA treatment (p < 0.001) and between flower position and GA treatment (p < 0.001). a Mean silique-set frequencies in wild-type and ga20ox mutant inflorescences averaged across flower positions 1–10, under control growth conditions (black) and exogenous GA treatment (white). b Mean silique-set frequencies for individual flower positions 1 through 10 averaged across all genotypes, under control growth conditions (black) and exogenous GA treatment (white). Values shown are the mean of 12 independent inflorescences ± S.E. Pairwise comparisons between genotypes, GA treatments and flower positions were made using LSD values at a 1% significance threshold (See Online Resource 1). Letters denote significant difference (p < 0.01) from wild type under control growth conditions (black) or GA treatment (grey). Genotypes marked with different letters are significantly different from each other. Asterisks denote a significant effect of GA treatment within a genotype (a) or flower position (b)
