Figure 8.

Tissue-specific concentration of H₂O₂ in MG (green bars) and RR (red bars) bittersweet fruits (A), as well as activities of antioxidant enzymes: CAT (B), APX (C), POX (D), SOD (E), PPO (F). Values are presented as means of three biological replicates and standard errors. Samples denoted by the same letter are not significantly different (p ≤ 0.05) according to Fisher’s LSD test. Abbreviations: CAT—catalase; APX—ascorbate peroxidase; POX—peroxidase; SOD—superoxide dismutase; PPO—polyphenoloxidase.
