Impact of the Arbuscular Mycorrhizal Fungi and Bacteria on Biocontrol of White Root Rot in Fruit Seedlings

This currently investigation aimed to evaluate the synergistic effect of the arbuscular mycorrhizal fungus (AMF), Gigaspora margarita, and the bacteria Paenibacillus rhizospherae on the alleviation of white root rot of Japanese apricot (Prunus mume) seedlings. Three experiments were carried out to evaluate that. In the first one, J.apricot “Nanko” seedlings were inoculated with (5, 10 and 20 %)inoculums containing the pathogen Rosellinia necatrix (NRBC 5954). In the second experiment the same kind of seedlings were submitted to four treatments: Control (C), AMF (A), Bacteria (B), AMF+Bacteria (A+B). Disease severity, root infection and AMF colonization were evaluated in this experiment.
