Percentage area of necrosis on cherry shoots inoculated with P. syringae for four cherry cultivars (plotted on a log scale with back-transformed values as the scale). Cv Van is universally susceptible, whilst cv Merton Glory has tolerance/lower susceptibility. Cv Napoleon is resistant to Psm R2 but susceptible to R1 and vice versa for cv Roundel. The control was sterile 10Â mM MgCl2. The mean values were calculated using ANOVA. LSD Least Significant Difference
