Although growth of two yeast strains characterized by consistent production of two diploid spores per ascus was inhibited in complex presporulation media containing amitrole, a fraction of the cells produced were able to form asci with more than two spores after transfer to acetate sporulation medium. Cells grown in a defined presporulation medium containing amitrole did not acquire this ability. The increase in spore numbers per ascus is attributed either to the induction by amitrole in growth medium of cells with more than one nucleus or to the restoration of normal meioses in the multispored asci.
尽管在含有杀草强的复杂产孢前培养基中，两种以每个子囊稳定产生两个二倍体孢子为特征的酵母菌株的生长受到抑制，但转移到醋酸盐产孢培养基后，所产生的一部分细胞能够形成含有两个以上孢子的子囊。在含有杀草强的限定产孢前培养基中生长的细胞没有获得这种能力。每个子囊孢子数量的增加要么归因于杀草强在生长培养基中对具有多个细胞核的细胞的诱导，要么归因于多孢子子囊中正常减数分裂的恢复。
