Take-all is one of the most important wheat soil-borne diseases caused by Gaeumannomyces graminis. The research objective was determination of Glomus spp. and methyl jasmonate effect on resistance induction of wheat take-all infected seedlings.The experiment was carried out based on completely randomized design in factorial with 32 treatments and three replications in greenhouse condition.The factors were presence or absence of pathogen, mycorrhizal fungi species including Glomus intraradices, G. mosseaeand G. hoi inoculation and methyl-jasmonate added in four concentrationsof 0, 0.1, 0.5 and 1.5mM. Induced resistance factors were added to surrounding soil in seedling stage and total phenol were measured after 24 and 120 hours inoculation.Total phenolactivity in healthy plants was more than infected and induced plant in most of the treatments. Total phenol in infected seedling after 120 hours was more than in 24 hours with all induced resistance factor. However, healthy seedlings had more total phenol after 24 and 120 hours. Application of G. intraradicesalong with 1.5mM of methyl jasmonate had the greatest impact on induced resistance. Therefore, it is recommended to be used as fertilizer for resistance inducing to take all disease in wheat.
