title: [Cell morphology, nucleus distribution and DNA content in haploid and diploid Aspergillus niger strains].
abstract: The cells of haploid Aspergillus niger strains contain, on the average, 7-9 nuclei, a fragment of a thin hypha 100 me long comprising 11-19 nuclei. The cells of a diploid strain are 1.5-2.6 times larger in volume. The diploid cells contain less nuclei and more cytoplasm per nucleus as compared to the haploid strains. The primary sterigmae of Aspergillus niger comprise 3-13 nuclei, the secondary sterigmae and conidia, one nucleus. The conidia of the diploid strains are 1.8-2.0 times larger in volume and contain twice as much DNA as compared to the haploid strains.
