Data are presented as means ± standard deviation, n = 3, for each organ in each accession. The antioxidant activity was expressed as RC50 values, meaning that a higher value corresponds to lower antioxidant potential. RC50 = extracts concentration with 50 % antioxidant potential; LSV = leaves and stem in the vegetative stage; LSF = leaves and stem in the flowering stage; LSS = leaves and stem in the seed set stage; FF = flowers in the flowering stage; SS = siliques in the seed set stage. Mean values in the same column followed by the different capital letters indicate significant differences in the accessions RC50, while averages with different small letters indicate significant differences in the RC50 for the organs at p < 0.05.
