Abstract
Salt (NaCl) induced changes of morphological and biochemical parameters were investigated in Aegiceras corniculatum L. Blanco supplemented with an increasing concentration of NaCl (0 mM, 100 mM, 150 mM, 200 mM, 250 mM and 300 mM). The plant height, stem diameter, dry weight, number of leaves and number of branches per plant were studied and found to be maximum in plants grown in 250 mM concentration of NaCl comparable to others. Biochemical test like total protein, total sugar, chlorophyll and carotenoid contents from leaf samples were performed. No significant changes were observed in total chlorophyll content among 0 and 30 days of NaCl treatment, however an increment was noticed in all the salt treated samples than that of control. The total soluble protein and sugar content were decreased under salinity condition even in both the 30 and 60 days of supplementation. From this experiment it may be concluded that the mangrove plant Aegiceras corniculatum can be sustained and propagated in optimum (250 mM) salinity under green house condition.
