Values are means ± S.D. (n = 3). The different letters indicate statistically significant differences between treatments at p < 0.05, using Tukey’s post-hoc test. APX—ascorbate peroxidase (EC 1.11.1.11); CAT—catalase (EC 1.11.1.6); POD—nonspecific peroxidase (EC 1.11.1.7); PPO—polyphenol oxidase (EC 1.14.18.1); TBARS—thiobarbituric acid reactive substances.
