CK control, LEFL L. enzymogenes CQ18 fermentation liquid. The colonies were counted on whole plant leaves. In each row means followed by different capital letters are significantly different at P ≤ 0.05 among the treatments. In each column, means followed by different lowercase letters are significantly different at P ≤ 0.05 during observation days (least significant difference (LSD) multiple range test)
