Seasonal variation in the biochemical constituents of Gracilaria spp. withreference to growth

The Biochemical constituents such as protein, carbohydrate and lipid of thr ee different species of Gracilariai viz: G.edulis, G.corticata and G.crassa were analysed and compared with the growth of the plant in different month s. Carbohydrate content showed significant positive correlation with the gr owth (g/m(2)) of the plant but a reciprocal relationship was obtained with protein and lipid content in different species of Gracilaria. The relations hip between the size and the biomass could be able to establish the recruit ment pattern of the plants in different period in G.edulis and G.corticata. The carbohydrate content was found to be more in G.edulis, whereas the pro tein content was dominant in G.corticata.
