Conidia of domesticated yellow-green aspergilli from strains of Aspergillus oryzae (Ahlburg) Cohn and Aspergillus sojae Sakaguchi and Yamada ex Murakami, used in the preparation of koji inoculum, germinate approximately 3 h sooner than conidia produced by related wild species, Aspergillus flavus Link ex Fr. and Aspergillus parasiticus Speare. There was no consistent relationship between average conidium size and estimated 50% germination time. Germination trials were conducted on Czapek agar at 28 degrees C. A hypothesis is offered that, in the propagation of koji inoculum, selection has favored those individuals capable of rapid conidium germination and germ tube extension, attributes that enable them to gain the available substrate during intraspecific competition.
驯化的黄-绿曲霉的分生孢子，来自米曲霉（Ahlburg）Cohn 和大豆曲霉（Sakaguchi）和山田 ex Murakami 的菌株，用于制备曲种接种物，比相关野生种黄曲霉（Link）ex Fr. 和寄生曲霉（Speare）产生的分生孢子早发芽约 3 小时。分生孢子大小的平均值与估计的 50%发芽时间之间没有一致的关系。发芽试验在 28°C 的察氏琼脂上进行。提出了一个假说，即在曲种接种物的繁殖过程中，选择有利于那些能够快速萌发分生孢子和延长芽管的个体，这些特性使它们能够在种内竞争中获得可用的基质。
