* Statistical significance for cultivar (C), tissue (T) and the interaction of both types (C × T). Means shown in a,b,c are significantly different at p < 0.05 between cultivars. Means shown in x,y are significantly different at p < 0.05 between tissues. FRAP: Ferric Reducing Ability of Plasma and CUPRAC: Cupric Ion-Reducing Antioxidant Capacity.
