Effect of environmental factors on spore shedding in Gracilaria corticata J.Agardh

Gracilaria corticata is an agarophyte which occurs abundantly throughout the year in the intertidal rocky surfaces of Visakhapatnam coast, India. Spore shedding experiments such as effect of environmental factors on spore shedding and on diurnal periodicity of spore shedding were conducted during 2007 and 2008. Maximum numbers of tetraspores were released when fronds were in submerged condition, exposed to dark condition and at 30 ‰ salinity. Neither acceleration nor delay in the peak shedding of tetraspores in G. corticata was found even after exposure to various periods of desiccation, salinities and different light intensities.
