| Abstract: | Elicitor prepared from the Fusarium oxysporum f. sp cubense (Foc) isolated from infected banana rhizosphere induced the accumulation of resistance-associated enzymes in leaves of susceptible and resistant variety of banana. Roots of Grand Naine (susceptible) and robusta (resistant) variety were inoculated with 1 g/l Foc elicitors. Distinct difference in peroxidase, polyphenol oxidase, β-1,3-glucanase, chitinase and phenolics was observed in control plants of resistant and susceptible varieties. Induced defence-related enzymes in susceptible variety were increased tothe level of untreated resistant variety. This depicted that Fusarium-derived elicitor effectively induced defence in susceptible variety to the apparent level of untreated resistant variety. |
