The fungi isolated from 100 samples of flue-cured tobacco from 12 markets in 2 tobacco belts comprised 11 genera, including 10 species of Aspergillus. The mean percentage per sample isolated from 62 samples of tobacco from Middle Belt markets was Alternaria, 40.6%; Aspergillus niger, 47.8%; Aspergillus repens, 38.0%; and Penicillium, 25.8%. The mean percentage per sample isolated from 38 samples of tobacco from Old Belt markets was Alternaria, 74.0%; Penicillium, 52.5%; Aspergillus repens, 38.0%; and Aspergillus ruber, 36.2%. Damaged (74 samples) and nondamaged (26 samples) stored tobacco yielded species of six genera of fungi, including eight species of Aspergillus. Species of Aspergillus and Penicillium were commonly isolated from both damaged and nondamaged tobacco, whereas species of Alternaria, Cladosporium, Fusarium, and Rhizopus were isoalted more frequently from nondamaged tobacco. The fungi that occurred in the highest population in damaged tobacco were Aspergillus repens, A. niger, A. ruber, and Penicillium species.
从两个烟草种植带12个市场的100份烤烟样本中分离出的真菌包括11个属，其中有10种曲霉。从中部种植带市场62份烟草样本中分离出的真菌，每份样本的平均百分比为：链格孢属，40.6%；黑曲霉，47.8%；匍匐曲霉，38.0%；青霉属，25.8%。从旧种植带市场38份烟草样本中分离出的真菌，每份样本的平均百分比为：链格孢属，74.0%；青霉属，52.5%；匍匐曲霉，38.0%；红曲霉，36.2%。受损（74份样本）和未受损（26份样本）的储存烟草产生了6个真菌属的菌种，其中包括8种曲霉。曲霉属和青霉属菌种通常在受损和未受损烟草中均可分离到，而链格孢属、枝孢属、镰刀菌属和根霉属菌种在未受损烟草中分离频率更高。在受损烟草中数量最多的真菌是匍匐曲霉、黑曲霉、红曲霉和青霉属菌种。
