    Apples were exposed to various concentrations of roseotoxins – metabolites od Trichothecium roseum and kinetic fluorescence imaging was used to detect the area influenced by the phytotoxin. Contrast was quantified within these fluorescence images between the areas exposed to roseotoxins and the untreated areas. It was proved that roseotoxin B is able to penetrate apple peel and to produce chlorotic lesions. Activity of roseotoxin B is similar as the activity of destruxins, host specific phytotoxins of Alternaria brassicae on canola.

    Zde byla jablka vystavena různým koncentracím roseotoxinů, metabolitů houbu Trichothecium roseum. Kinetická zobrazovaní fluorometrie byla použïta k detekci a identifikaci plochy, která byla zasažena fytotoxinem. Dokázali jsme, že roseotoxin B proniká jablečnou slupkou a způsobuje chlorózu u zasažených pletiv. Aktivita rosetoxinu B je podobná aktivitě destruxinů na řepce, které jsou specifickými fytotoxiny houby Alternaria brassicae.
