Effects of cinnamic acid on the growth of faba bean seedlings after being inoculated with Fusarium oxysporum f. fabae (FOF). Data are average values, with bars representing standard errors of three replicates. Different letters for each index indicate significant differences at a level of p < 0.05, according to Duncan’s test. There are no significant differences among values labeled “ab”, “a”, and “b”.
