Artificial Inoculations

Fusarium head blight (FHB), caused by Fusarium spp., has become one of the most destructive diseases in the world’s wheat growing areas , especially in the humid and semihumid regions (Paillard et al. 2004, Mesterhazy 1978, Stack & Mullen 1985; Kiecana 1987; Kiecana et al. 1988). Six winter wheat cultivars, recently released and widely grown in Trasylvania, have been evaluated for FHB resistance during 2006. The evaluation was made by means of artificial inoculations with Fusarium graminearum and assesment of symptom intensity by computing AUDPC index (Area Under Developmental Progress Curve). Based on these data, two cultivars (Dumbrava and Turda 195) were considered as resistant, two cultivars (Ardeal and Arieşan) as medium resistant and other two cultivars (Fundulea 4 and GK Öthalom) as susceptible to FHB. The reaction to FHB of the six tested cultivars, based on the postharvest indices, showed significant differences among these cultivars as far as the yield elements and the total grain yield were considered. Actually, in the resistant cultivars, both the total grain yield and some of the yield elements (spike wight, grain weght/spike and 1000 kernel weigt) were significantly less affected by FHB than in medium resistant and susceptible cultivars.

Abstract Fusarium graminearum and F. culmorum are the causal agents of Fusarium head blight (FHB) in cereal crops worldwide. Application of resistant cultivars is the most effective and economic method for management of FHB and reducing mycotoxin production in wheat. Understanding the physiological and biochemical mechanisms involved in basal resistance of wheat to FHB disease is limited. In this research, after screening resistance levels of eighteen wheat cultivars planted in Iran, Gaskozhen and Falat were identified as partially resistant and susceptible wheat cultivars against Fusarium spp., respectively. Also, we investigated the role of hydroxyl radical (OH−), nitric oxide (NO), callose deposition, lipid peroxidation and protein content in basal resistance of wheat to the hemi-biotrophic and necrotrophic Fusarium species causing FHB. Nitric oxide as a signaling molecule may be involved in physiological and defensive processes in plants. Our results showed that NO generation increased in seedlings and spikes of wheat cultivars after inoculation with Fusarium species. We observed earlier and stronger callose deposition at early time points after infection by Fusarium spp. isolates than in non-infected plants, which was positively related to the resistance levels in wheat cultivars. Higher levels of OH− and malondialdehyde (MDA) accumulation (as a marker of lipid peroxidation) were observed in the Falat than in the Gaskozhen cultivar, under non-infected and infected conditions. So, estimation of lipid peroxidation could be useful to evaluate cultivars’ susceptibility. These findings can provide novel insights for better recognition of physiological and biochemical markers of FHB resistance, which could be used for rapid screening of resistance levels in wheat cultivars against this destructive fungal disease.
