The formation of deoxynivalenol in a maize plot inoculated with Fusarium culmorum was studied over a growing season. Already three weeks after inoculation 4.9 mg/kg of DON were measured in the infected ears. The toxin concentration increased continuously up to harvest after eight weeks to a value of 261 mg/kg. Ensilage experiments in laboratory scale silos have shown that the DON content of naturally contaminated corn-cob-mix was not reduced during the ensilage process. It was concluded that infection of maize plants by toxin-producing Fusarium species followed by DON production in the field seems to be the most probable way of contamination of maize silage with this mycotoxin.
在一个生长季节中，研究了接种禾谷镰刀菌的玉米地块中脱氧雪腐镰刀菌烯醇的形成情况。接种后仅三周，在受感染的玉米穗中就检测到4.9毫克/千克的脱氧雪腐镰刀菌烯醇。毒素浓度持续增加，直至八周后收获时达到261毫克/千克。实验室规模青贮窖的青贮实验表明，天然污染的玉米芯混合物在青贮过程中脱氧雪腐镰刀菌烯醇含量并未降低。得出的结论是，产毒素的镰刀菌属物种感染玉米植株，随后在田间产生脱氧雪腐镰刀菌烯醇，似乎是这种霉菌毒素污染玉米青贮饲料最可能的途径。
