Fig. 4. Preventive effect of pomegranate extract (PGE) on incidence of decay (columns) and rot diameter (dots) of lemons, grapefruits and apples. Fruit were treated with PGE
at different concentrations (12,1.2 or 0.12 g/l) and inoculated 1 h later with Penicillium italicum or P. digitatum (lemons), P. digitatum (grapefruits) or P. expansum (apples). Mock
treated fruit with a solution of 1% citric acid and inoculated with the pathogens, served as controls. Bars indicate standard errors of the means. For each host/pathogen
combination, columns and dots with different letters are statistically different according to the Duncan’s test (P 0.05). Letters on the top of the figure refer to the columns.
