The mold flora of seeds of twelve varieties of winged beans was determined both before and after surface disinfections. When seeds were surface disinfected, mold fungi were detected in 73% of the seeds whereas 81% of the seed that was not disinfected produced mold fungi. Aspergillus spp. was most frequently present while Penicillium spp. occurred in seed of 4 varieties and in less than 4% of the seed. Twelve isolates of A. flavus and A. parasiticus were examined for their ability to produce aflatoxins. Whether aflatoxins were produced and the amount of each varied according to the origin of the isolate and the species of Aspergillus. For example all A. parasiticus isolates produced at least 2 aflatoxins whereas 4 of the A. parasiticus isolates were non-toxigenic. When ground seeds of winged beans were inoculated with an aflatoxigenic strain of A. parasiticus the level of aflatoxins that occurred varied with the variety, however, the level of aflatoxin was higher in winged bean than in peanut tissue and 6 of the 12 winged bean varieties contained higher levels of aflatoxins than rice.
对12个品种四棱豆种子的霉菌菌群在表面消毒前后进行了测定。种子进行表面消毒后，73%的种子检测到霉菌，而未消毒的种子中有81%产生了霉菌。曲霉属最为常见，青霉属出现在4个品种的种子中，且占种子总数不到4%。对12株黄曲霉和寄生曲霉分离株产生黄曲霉毒素的能力进行了检测。是否产生黄曲霉毒素以及每种黄曲霉毒素的产量因分离株的来源和曲霉种类而异。例如，所有寄生曲霉分离株至少产生2种黄曲霉毒素，而4株寄生曲霉分离株不产毒。用产毒的寄生曲霉菌株接种四棱豆磨碎的种子后，黄曲霉毒素的产生水平因品种而异，然而，四棱豆中黄曲霉毒素的水平高于花生组织，12个四棱豆品种中有6个品种的黄曲霉毒素水平高于大米。
