Total phenols (A,B), ascorbic acid amount (C,D) and antioxidant capacity (E,F) in the green (A,C,E) and red (B,D,F) fruit produced by the three pepper landraces “Cuerno” (C), “Valencia” (V), and “Sueca” (S) grafted (G) or ungrafted (U) on rootstock F1 NIBER^®. Values are the mean ± SE of three fruits per replicate (3 replicates) per landrace. Means were subjected to a two-way ANOVA with grafting and landrace as sources of variability. Different letters for factors grafting and landrace, or their interaction, indicate significant differences at p < 0.05 using the LSD test. No letter indicates the non-significance of the F ratio.
