| 摘 要： | 试验测定了分离自中国小麦赤霉病常发生地区病麦穗上的47个禾谷镰刀菌(Fusariumgraminearum)菌株的产毒紊能力。结果表明，它们可以产生25种包括单端孢霉烯族化合物(Trichothecenes)、倍半萜类化合物(sesquiterpenes)、赤霉烯酮(Zearalenone)和丁烯羟酸内酯(Butenolide)等类的已知次生代谢物。这些菌株属于化学型 I，其中，来自我国温暖麦区的菌株都属化学型IA (deoxynivalenol，3-acetyl)，并在气候冷凉地区发现化学型IB(de-oxynivalenol，15-acetyl)菌株。

| Abstract: | The ability of 47 isolates of Fusarium graminearum from different provinces of China to produce mycotoxins both in liquid cultures (MOSS, MYRO and GYEP) and on rice was assessed. The toxins produced were assessed by analyzing the metabolites by GC, HPLC and GC/MS. Twenty five metabolites produced included zearalenone, butenolide and various trichothecenes. All Fusarium graminearum strains tested had a chemotype I (deoxynivalenol). Most of Chinese strains of F. graminearum from warmer regions were chemotype IA (deoxynivalenol, 3-acetyl). The strains, which were collected from the slightly cooler provinces (Henan, Shaanxi, Heilong-jiang and mountain area of Fujian) had a chemotype 1B (deoxynivalenol, 15-acetyl). |
