[Interaction of Pantoea agglomerans with the agent of basal bacteriosis of wheat].

Interactions between the agent of basal bacteriosis Pseudomonas syringae pv. atrofaciens and epiphyte Pantoea agglomerans have been studied in the laboratory and field conditions. It is shown the P. agglomerans affects the infectious process caused by P. s. pv. atrofaciens that leads to intensification of symptoms of the disease development. The epiphyte cells accumulation predominates under mutual artificial infection in the infected tissue. The higher competitive ability of the epiphyte P. agglomerans as compared with phytopathogen has been found out. The epiphyte propagates more quickly and inhibits growth and development of phytopathogen under joint cultivation of the studied strains of bacteria. Competition is shown between the studied strains of bacteria on the wheat leaf surface which depended on the phase of plant development.
