| Abstract:
Pseudomonas syringae pv. syringae plays an important role in apoplexy disease of apricot, leaf spot disease on sour-cherry and bacterial blight on pepper leaves in Hungary. The host specificity, ice-nucleation-activity and antigenic structure of bacterial strains isolated from different hosts were compared. The pathogenicity of P. syringae strains were not homogeneous. All strains except one were ice-nucleation-active. Antigenic structure of bacterial strains investigated by cross-immunoelectrophoresis technique were also not homogeneous but the pepper strains contained one common precipitin peak which may correlate with their host specificity. | |
