Culture of agar yielding red alga Gracilaria edulis was carried out in fibreglass
tanks by providing running seawater and aeration under a shed with transparent
roof. The seed material was pretreated for 12 hours at different concentrations of
growth promoters IAA, IBA, GA, Ascorbic acid, EDTA and Inositol. In general,
more increase in growth and biomass was obtained in the plants pretreated with
lower concentrations of these growth promoters
