Changes in antioxidant system indicators of eliminating ROS after Se and TR4 treatments, as well as POD activity (A), PPO activity (B), SOD activity (C), CAT activity (D), GSH-Px activity (E), and GSH concentration (F). Data are presented as the mean ± SE, with n = 5 replicates. The letters a–c represent the statistical significance determined using Student’s t-tests, and the absence of shared letters signifies a significant difference at the p < 0.05 level. Note: CK: control; Se: banana leaves treated with Se for 21 d; ST7d: banana leaves treated with Se for 21 d and Foc TR4 for 7 d; ST14d: banana leaves treated with Se for 28 d and Foc TR4 for 14 d; ST21d: banana leaves treated with Se for 35 d and Foc TR4 for 21 d; ST28d: banana leaves treated with Se for 42 d and Foc TR4 for 28 d; ST42d: banana leaves treated with Se for 56 d and Foc TR4 for 42 d. The concentration of Se treatment was 40 mg/L.
