Figure 6From: Hydrogen peroxide induced by the fungicide prothioconazole triggers deoxynivalenol (DON) production by Fusarium graminearumEffect of exogenously applied H 2 O 2 on germination (a, b, c) of F. graminearum and DON production (d,e,f) after 4 h (a and d), 24 h (b and e) and 48 h (c and f). Conidia at a concentration of 106 conidia/ml were challenged with a tenfold dilution series of H2O2. For each treatment and repetition 50 conidia were scored for their germination after staining with 0.02% of cotton blue in lactic acid and percentage of conidial germination was calculated. DON content in the medium was determined using a competitive ELISA approach. Each treatment was measured in duplicate and the experiment was repeated twice in time (dashed and solid line represent the two experiments).Back to article page
