During germination, the first dry weight increase of the spore population was detected after 3 h incubation and the first germ tube appeared after 4 h. The total DNA of the culture sharply increased after 5 h, followed by a pause at 6 h. At this time the DNA content per nucleus was maximal and the first nuclear divisions were detected. Pauses in the rise of total DNA of the culture and in the [14C]adenine incorporation pattern suggest that there is partial synchrony in DNA synthesis at the beginning of incubation. This is also supported by the fact that until 8 h, only hyphae with 1, 2 and 4 nuclei were observed. [14C]adenine incorporation into DNA averaged 2·68% of the total taken up in 10 h incubation., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-88-2-245
