The functional analysis of pretreated melatonin and 5-methoxyindole with the fungus compound inhibitors (H2O2, CFW and Congo red) together. (A) The fungus F. graminearum PH-1 was grown in the medium CM after being treated with using melatonin and fungus compound inhibitors (H2O2, CFW, and Congo red) together for 3 days. (B) The fungus F. graminearum growth in the medium CM after treating 5-methoxyindole with the fungus compound inhibitors (H2O2, CFW, and Congo red) together for 3 days. The experiment was repeated independently three times, and 0.05% (vol/vol) methanol/water served as the ck. The error bars represent the mean standard deviation of each treatment repeated three times with three replicates. The letters above the columns indicate significant differences. The significant difference between the treatments was determined through Tukey’s HSD test at p ≤ 0.05.
