Effect of cinnamic acid on seedling root physiological activity and content of malondialdehyde (MDA) after being inoculated with FOF. Data are average values, with bars representing standard errors of three replicates. Different letters for each index indicate significant differences at p < 0.05, according to Duncan’s test. There is no significant difference among values labeled “ab”, “a”, and “b”.
