What is Gamete Expulsion and Release in Sargassum muticum about?
Both in the sea and in culture the brown seaweed Sargassum muticum (Yendo) Fensholt expels eggs in a number of pulses, at intervals of several days. In nature, most of the receptacles on an individual plant exude eggs simultaneously. Isolated branches cultured under the same conditions initially expel their eggs in synchronous pulses, although this synchrony and the discreetness of the pulses eventually breaks down. The very first expulsion invariably occurs about two days after a full or new moon, but the timing of subsequent pulses depends on the culture conditions. In the absence of lunar entrainment, higher water temperatures shorten the interval between successive emissions. The rhythm of gamete emission continues normally for some time in continuous darkness. It seems, however, to be inhibited in continuous illumination, although it can be restored by a single dark period. The eggs are not released immediately following extrusion. Even in moderately turbulent conditions they are retained for at least 24-48 h, clinging tenaciously to the parent receptacle. After this period the dissolution of their anchoring mechanism facilitates their release. Retention of the ova on the rece
