Deoxynivalenol and Oxidative Stress Indicators in Winter Wheat Inoculated with Fusarium graminearum

摘要: This study comprises analyses of contents mycotoxins, such as deoxynivalenol and zearalenone, well the level oxidative stress in ears a susceptible wheat cultivar Hanseat cv. Arina, resistant to pathogenic fungus Fusarium graminearum. Starting from 48 h after inoculation, marked increase was observed these mycotoxins wheat; however, greatest accumulation recorded late period i.e., during development disease. Up 120 both cultivars, higher than that zearalenone. The characterized by much greater cultivar. At same time, this cultivar, time 0 72 post-infection generation superoxide radical (O2•−). Additionally, its level, at all points control. In markedly O2•− relation control found up two hours inoculation and, next, later inoculation. turn, semiquinone radicals detected electron paramagnetic resonance (EPR) increased culture times, Arina; infested wheat, it generally lower Analysis disease symptoms revealed presence more extensive lesions Arina. ergosterol fungal growth indicator
