Resistance of the AM Fungus Eucalyptus Seedlings against Pseudomonas solanacearum

Eucalyptus Seedlings inoculated with AM fungi could increase resistance against Pseudomonas solanacearum.While treating with AM fungi,Eucalyptus Seedlings could not occur of little occur in wilt disease damage.The results,injected Pseudomonas solanacearum bacteria for a series of Eucalyptus seedlings,showed that disease percentage of inoculated seedlings decreased by 10.0%～40.0%,and seedling increased by 12%～39% in height growth.AM fungus effectiveness was better than that of ECT mycorrhizal fungi,the isolate AM6008 and AM9004 were better fungi to resist the wilt bacteria,followed by AM3006.Field trial results indicated that mycorrhizal seedlings could improve resistance against the bacteria,and the disease percentage decreased by 10.0%～17.5%,although environmental factors were more different.
