本文对从南非当地粮食中得到的不同镰刀菌种,进行了培养与毒性试验。并对部分有毒菌种进行了串珠镰刀菌毒素的产毒测定。用对鸭雏引起死亡作为毒性的评价,并在玉米上培养和在田间玉米植株上接种,比较两者产生串珠镰刀菌素的能力。串珠镰刀菌素的测定,除对一个菌株用薄层色谱法外,其余均用高压液相色谱法。共试验了258株镰刀菌,65%的菌株对鸭雏具有高毒性(3～4/4死亡),而13%的菌株无毒性。所有试验的40株镰状镰刀菌(F. fu-
In this paper, different Fusarium species obtained from local South African food were tested for toxicity and toxicity. Some toxin strains were also tested for the toxin production of Fusarium moniliforme toxins. Ducklings were caused to die as a sign of toxicity and cultured on maize and inoculated on field corn plants to compare the ability of the two to produce moniliformin. Determination of fusarium moniliforme, in addition to a strain by thin-layer chromatography, the rest are high pressure liquid chromatography. A total of 258 Fusarium species were tested, 65% of which were highly toxic (3-4 deaths) to ducklings, while 13% were non-toxic. Forty Fusarium strains of F. fu-
