The fungal odor compounds 3-methyl-1-butanol, 1-octen-3-ol and 3-octanone were monitored in nine experimental bins in Winnipeg, Manitoba containing a hard red spring wheat during the autumn, winter and summer seasons of 1984-85. Quality changes were associated with seed-borne microflora and moisture content in both ventilated and non-ventilated bins containing wheat of 15.6 and 18.2% initial moisture content. All three odor compounds occurred in considerably greater amounts in bulk wheat in non-ventilated than in ventilated bins, particularly in those with wheat having 18.2% moisture content. The presence of these compounds usually coincided with infection of the seeds by the fungi Alternaria alternata (Fr.) Keissler, Aspergillus repens DeBarry, A. versicolor (Vuill.) Tiraboschi, Penicillium crustosum Thom, P. oxalicum Currie and Thom, P. aurantiogriesum Dierckx, and P. citrinum Thom. High production of all three odor compounds in damp wheat stored in non-ventilated bins was associated with heavy fungal infection of the seeds and reduction in seed germinability. High initial moisture content of the harvested grain accelerated the production of all three fungal volatiles in non-ventilated bins.
1984 - 1985年秋冬夏三季，在加拿大曼尼托巴省温尼伯市的9个实验仓中，对硬红春小麦中的真菌气味化合物3 - 甲基 - 1 - 丁醇、1 - 辛烯 - 3 - 醇和3 - 辛酮进行了监测。质量变化与种子携带的微生物群落以及初始含水量为15.6%和18.2%的通风和不通风仓中小麦的水分含量有关。在不通风仓的散装小麦中，这三种气味化合物的含量比通风仓中的要多得多，尤其是在含水量为18.2%的小麦中。这些化合物的存在通常与种子被链格孢（Alternaria alternata (Fr.) Keissler）、曲霉（Aspergillus repens DeBarry）、杂色曲霉（A. versicolor (Vuill.) Tiraboschi）、 crustosum青霉（Penicillium crustosum Thom）、草酸青霉（P. oxalicum Currie and Thom）、桔灰青霉（P. aurantiogriesum Dierckx）和桔青霉（P. citrinum Thom）感染有关。在不通风仓中储存的潮湿小麦中，这三种气味化合物的大量产生与种子的严重真菌感染以及种子发芽率降低有关。收获谷物的高初始含水量加速了不通风仓中所有三种真菌挥发物的产生。
