Influence of leaf extract on the antibacterial activity of BP100 alone or combined with lysozyme. The effect was measured as the growth inhibition of E. amylovora suspension in each treatment respect the nontreated control after exposure to 2.5, 1.25 and 0.625 μM peptide concentrations without lysozyme or with lysozyme 0.50 mg/ml. The peptide assay was carried out in water (□) or in pear leaf extracts diluted at 10% (gray square). Two independent experiments, assay 1 (a) and assay 2 (b), were performed. The confidence intervals for the means are indicated on top of the bars. Letters over the bars indicate the significance of the difference between treatment extracts (P ≤ 0.05), according to Waller-Duncan’s test
