The investigations are made of cherry biological peculiarities and disease excitants composition. The domination of necrotrophic fungi and Pseudomonas syringae van Hall bacteria in pathocenosis is shown. The fact of microbiota associative lesion of plants is established. The antagonist action of isolated bacterium in relation to Cytospora leucostoma (Pers.) Sacc., Alternaria alternata Keissl., Fusarium oxysporum Schlecht., Monillia cinerea Bonord is detected. The character of isolated bacterium metabolites, pathogenic fungi and their association effect on a host-plant is established. The ability of bacterium to lower the activity of phytotoxins secretion in fungi when cultivated together is identified. It has been found that it is the fungal pathogens causing the development of die-back in cherry in investigated gardens, whereas P. syringae bacterium, when in latent state, plays a part of protector and permits to suppress the development of fungal infection. Taking into account the fact that this bacterium is pathogenic, the works of advanced breeding for resistance of the horticultural crops to bacterial blight are recommended. |
