Aspergillus flavus and Aspergillus niger group colonization of deep-plowed, decomposing rye green manure cover crops in peanut field soils was studied in four fields during 1972 and 1973; colonization of decomposing peanut fruits was studied in 1972 in two fields. A. flavus colonization of rye and peanut fruits was greater in soils of heavy texture, and an A. flavus population as high as 165 propagules per g of soil was observed in soil adjacent to rye, whereas A. flavus populations in soils not associated with rye were 18 propagules per g of soil or lower. Highest A. flavus populations in soil adjacent to decomposing peanut fruits were usually comparable to populations associated with rye. Little decomposing rye or peanut fruit colonization was generally observed by the A. flavus competitor, A. niger group. A. flavus may maintain or increase its inoculum potential by colonization of these and other moribund plant tissues.
1972年和1973年期间，在四块田地中研究了黄曲霉和黑曲霉群在花生田土壤中深耕、分解的黑麦绿肥覆盖作物上的定殖情况；1972年在两块田地中研究了它们在分解的花生果实上的定殖情况。在质地较重的土壤中，黄曲霉在黑麦和花生果实上的定殖情况更为严重，在与黑麦相邻的土壤中观察到黄曲霉种群数量高达每克土壤165个繁殖体，而在与黑麦不相关的土壤中，黄曲霉种群数量为每克土壤18个繁殖体或更低。与分解的花生果实相邻的土壤中，黄曲霉的最高种群数量通常与与黑麦相关的种群数量相当。黄曲霉的竞争者黑曲霉群通常很少在分解的黑麦或花生果实上定殖。黄曲霉可能通过在这些以及其他濒死植物组织上定殖来维持或增加其接种潜力。
