Description
Summary:Bostrychia tenella (Vohl.) J. Ag. and Caloglossa leprieurii (Mont.) J. Ag., two examples of species important for human consumption from estuaries in Asia, were studied with respect to spore formation and release with a long-term view to their mass cultivation. Plants were collected between Jan and Dec 1987 from three different regions of the Gautami Godavari estuary, India. Both species behaved rather similarly. Tetrasporophytic plants were present throughout the year, whereas carposporophytic plants were found only in certain months. Shedding of tetraspores was observed throughout the year, but with seasonal difference in their output. Carpospores were liberated from Oct to May when the material was available. Maximum shedding of carpospores and tetraspores was observed in Dec and Jan and the minimum number of tetraspores in Aug and carpospores in May. The maximum number of spores was liberated, when plants were submerged at 20 ppt salinity.
