Abstract
The nuclear events in early embryonic development of Durvillaea potatorum were studied by light microscopy. The time course of development and the segmentation pattern of the zygote correspond to those in other Durvillaea spp. and to that in Fucus. Migration of the male nucleus and karyogamy occurred within 2-5 hours, followed by formation of a rhizoidal protuberance and an unequal cell division at 15-28 hours after mixing of gametes. Unfertilized eggs germinated parthenogenetically and underwent nuclear divisions. The haploid chromosome number was n = 31.
