Five Fusarium species were isolated from the grain of dent corn (Zea mays) selected from 20 of 32 damaged fields in 10 counties in Minnesota on the basis of hyphal growth visible on kernels in the field. Three mycotoxins were identified in the infected ears: zearalenone, deoxynivalenol, and 15-acetyl-deoxynivalenol. This is the first report of the presence of 15-acetyl-deoxynivalenol on corn ears in the field prior to harvest and in combination with deoxynivalenol and zearalenone. Ninety-nine cultures were selected from colonies growing from kernels on an agar medium; 30% of the cultures were F. graminearum, 23% were F. subglutinans, 20% were F. moniliforme, 14% were F. oxysporum, and 12% were F. proliferatum.
从明尼苏达州10个县32个受损田地中的20个田地挑选的马齿玉米(Zea mays)籽粒中分离出5种镰刀菌。根据田间籽粒上可见的菌丝生长情况进行挑选。在受感染的玉米穗中鉴定出三种霉菌毒素:玉米赤霉烯酮、脱氧雪腐镰刀菌烯醇和15 - 乙酰 - 脱氧雪腐镰刀菌烯醇。这是首次报道在收获前田间玉米穗上存在15 - 乙酰 - 脱氧雪腐镰刀菌烯醇,并与脱氧雪腐镰刀菌烯醇和玉米赤霉烯酮同时存在。从琼脂培养基上籽粒长出的菌落中挑选出99个培养物;30%的培养物为禾谷镰刀菌,23%为拟胶孢镰刀菌,20%为串珠镰刀菌,14%为尖孢镰刀菌,12%为轮枝镰刀菌。
