Oospore shedding in Sargassum wightii (Greville)udJ. Agardh and Turbinana conoides (J. Agardh)udKuetzing at different environmental factors

摘要

Experiments were conducted with the receptacles of reproductive plants of Sargmsum wight;;ud(Greville) 1. Agardh and Tllrbinaria conoides (1. Agardh) KuelZing to study the effect ofuddifferent environmental factor.; on the oospore output. The ability to liberate spores and theudquantity of spores shed in these two brown algae varied under the environmental factorsudtested. In general, submerged condition of plants, long day condition at low illuminance,udseawater of 30 to 40%. salinity and 25 to 35'C temperature were found to be suitable forudmaximum shedding of oosporcs in these two algin yield ing plants.
