Analysis of F. graminearum PH-1 conidiation treated with different concentrations of melatonin and 5-methoxyindole (A). The conidial spore germination of F. graminearum after being treated with the different concentrations of melatonin and the 5-methoxyindole (B). 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.
