Fig. 1. Effect of pomegranate extract (PGE) on viability of conidia expressed as
colony forming units (CFU) on potato dextrose agar (PDA) plates. Before plating
conidia of Botrytis cinerea,Penicillium digitatum or P. expansum were incubated in
PGE solutions at different concentrations (12, 1.2 or 0.12 g/l) for 20 h. Conidia
maintained in a 1% solution of citric acid served as a control. Bars indicate standard
errors of the means. For each pathogen, columns with different letters are
statistically different according to the Duncan’s test (P 0.05)
