Effect of nutritional enrichment of P. fluorescens EPS62e on susceptibility of flowers to infection by E. amylovora. Detached flowers of Passe Crassane (A) and Conference (B) pear were treated with nutrients alone or with EPS62e (10⁸ CFU ml⁻¹) amended with glycine (Gly), Tween 80 (Tween), or glycine plus Tween (GlyTween) or treated with water (nt). Flowers were treated with the cell suspension and after 24 h inoculated with E. amylovora at 10⁷ CFU ml⁻¹. Values are the means of three replicates. Error bars represent the 95% confidence intervals of the means. Bars with the same letter in the same panel do not differ significantly (P < 0.05) according to the Waller-Duncan test.
