Effects of Salinity Level on Biochemical Constituents of Heretiera fomes Buch-Ham.
and Excoecaria agallocha L. at the Three Saline Zones of the Sundarban Mangrove Forest
Biochemical constituents viz. protein and proline (Amino acid) content of early (6, 9 months) and grown-up ages (30 months) of Heritiera fomes Buch-Ham and Excoecaria agallocha L. seedlings were investigated at three saline zones viz. Chandpai (Oligohaline), Jungra (Mesohaline) and Munshiganj (Polihaline) of the Sundarban mangrove forest. In the leaf of early ages H. fomes showed comparatively higher protein content when grown in oligohaline zone but E. agallocha showed highest protein content when grown in mesohaline zone. But at the grown-up age, both species showed lowest content of protein. On the other hand, proline content showed highest in the leaf of early stage of H. fomes seedlings at the polihaline zone. But in the stem and the root of H. fomes seedlings found relatively higher proline content when grown in oligohaline zone. E. agallocha showed relatively highest proline content in the early age stems at oligohaline zone. In the grown-up age comparatively highest proline content was found in all parts of both species at polihaline zone. At this unfavorable saline environment, the species survive by accumulation of osmolytes like proline which prevents water loss and ion toxicity. So, their adaptation to high salinity is closely associated with proline accumulation.
