Abstract
SummaryThree varieties of plum were inoculated with the three viruses, plum line pattern (apple mosaic), prune dwarf and plum bark split, either singly or in combinations of line pattern with each of the others. Bark lesions developed more rapidly on Cambridge Gage trees infected with bark split virus alone than on those infected also with line pattern virus. Symptoms characteristic of line pattern virus on trees of Cambridge Gage, Early Laxton and Italian Prune were not affected by infection with the bark split virus, but were suppressed by the prune dwarf isolate. This suppression was apparently due to the presence of a mild strain of line pattern virus contaminating the prune dwarf inoculum.The occurrence of antagonistic strains of line pattern virus, differing in virulence, precludes any precise definition of diagnostic symptoms.
