One-hundred-and-thirteen isolates of Fusarium were tested for their ability to produce zearalenone on autoclaved corn. They belonged to the following species (number of producers per number tested): F. epispheria, (0/1); F. moniliforme, (0/8); Gibberella fujikuroi, (0/3); F. nivale, (0/7); F. oxysporum, (0/15); F. roseum, (31/51); F. solani, (0/9); F. tricinctum (3/19). The isolates of individual species produced the following amounts of zearalenone per gram of corn: 3 isolates of F. roseum (0.6 to 119 mug), 3 of F. roseum "Culmorum" (1 to 210 mug), 3 of F. roseum "Equiseti" (0.6 to 2.0 mug), F. roseum "Gibbosum" (115 to 175 mug), 21 of F. roseum "Graminearum" (0.2 to 230 mug), and 3 of F. tricinctum (0.2 to 6.0 mug). All isolates of F. roseum "Graminearum" which formed the perithecial stage of G. zeae (G. roseum) produced zearalenone. Production occurred by the wild but not the appressed cultural type. Zearalenone production by F. tricinctum was confirmed by a mouse bioassay.
对113株镰刀菌进行了测试，以检测它们在经高压灭菌的玉米上产生玉米赤霉烯酮的能力。它们属于以下物种（每个测试物种中产生玉米赤霉烯酮的菌株数量）：球孢镰刀菌（0/1）；串珠镰刀菌（0/8）；藤仓赤霉菌（0/3）；雪腐镰刀菌（0/7）；尖孢镰刀菌（0/15）；粉红镰刀菌（31/51）；茄病镰刀菌（0/9）；三线镰刀菌（3/19）。各个物种的菌株每克玉米产生的玉米赤霉烯酮量如下：3株粉红镰刀菌（0.6至119微克），3株粉红镰刀菌“禾谷镰刀菌变种”（1至210微克），3株粉红镰刀菌“木贼镰刀菌变种”（0.6至2.0微克），粉红镰刀菌“ Gibbosum”（115至175微克），21株粉红镰刀菌“禾谷镰刀菌”（0.2至230微克），以及3株三线镰刀菌（0.2至6.0微克）。所有形成玉米赤霉（赤霉菌）子囊壳阶段的粉红镰刀菌“禾谷镰刀菌”菌株都产生玉米赤霉烯酮。野生培养类型而非紧贴培养类型产生玉米赤霉烯酮。通过小鼠生物测定法证实了三线镰刀菌产生玉米赤霉烯酮。
