Abstract

Induced resistance of banana against blood disease (Ralstonia solanacearum Phylotipe IV) using endophytic bacteria. Endophytic bacteria play a role to control plant pathogenic bacteria indirectly by inducing the plant to increase production of the metabolites in activating the plant resistance. This study aimed to determine the ability of endophytic bacteria to induce resistance in banana plants against blood disease. Indicators of induced resistance of banana plant were analyzed through the existence of defense enzyme activities (peroxidase and polyphenol oxidase) and the amount of salicylic acid on banana roots. The results showed that endophytic bacteria isolates EAL15, EKK10, EKK20 and EKK22 suppressed the incidence of blood disease in Cavendish banana by 70-85%. Increased activity of peroxidase and polyphenol oxidase in roots of banana plants were higher in plants treated with endophytic bacteria compared to untreated plants. Salicylic acid content in banana plants treated with isolates EAL15, EKK10 and EKK20 was higher than that of EKK22 isolates and control plants.
