Effects of MeJA on DPPH(A,B), ABTS (C,D), and FRAP (E,F) in broccoli florets, stem, and leaves. DPPH: 2,2-di-phenyl-1-picrylhydrazyl radical scavenging capacity; ABTS: trolox-equivalent antioxidant capacity; FRAP: ferric-reducing antioxidant power; FW: fresh weight; Control: the plants were sprayed with distilled water; MeJA: the plants were sprayed with 40 μmol/L MeJA. The data are displayed with the mean ± SD of three replications. Values with ns, * and ** are significantly different at p > 0.05, p < 0.05, and p < 0.01.
