Effects of fertilizer treatments on components, performance components and induce resistance to wheat scab disease

Fusarium head blight (FHB) disease caused by Fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. In this study, the effects of different fertilizer treatments (Vermicompost, Chemical fertilizer and Mycorrhiza) on performance components and expression of several genes involved in disease resistance pathway was investigated. For this reason, Falat wheat cultivar was used in a completely randomized design with four repetitions in greenhouse conditions. The analysis of variance showed that the effects of different fertilizer treatments on 100-seed weight, plant height, weight per plant, seed performance, biological performance and the harvest index were significant at 1% probability level. The analysis of gene expression data showed that beta Glucanase and Oxalate Oxidase genes had a significant increase in all treatments but the highest increase was observed in vermicompost and chemical fertilizers mixture. The results indicated that the mix application of biologic and non-biologic fertilizers could be induce systemic acquire resistance in infected plants.
