Effect of two tested compounds, T34 and KPHI, on the antioxidant defense-related enzymes in P. cubensis-infected leaves under greenhouse conditions (A) catalase activity (µm H2O2 g−1FW min−1). (B) Peroxidase activity (µm Tetraguaiacol g−1FW min−1), and (C) polyphenol oxidase activity (Arbitrary unit) in experiment I. (D) catalase activity (µm H2O2 g−1FW min−1). (E) Peroxidase activity (µm Tetraguaiacol g−1FW min−1), and (F) polyphenol oxidase activity (Arbitrary unit) in experiment II.Values show the means ± standard errors. Different letters denote statistical differences among treatments according to Tukey’s HSD test (p < 0.05).
