Micronutrient or essential heavy metals viz. Copper (Cu), Zinc (Zn) and Iron (Fe) distribution trend were studied at the age of 6, 9 and 30 months old Heritiera fomes seedlings at three distinct saline zones viz. Chandpai (Oligohaline), Jungra (Mesohaline) and Munshiganj (Polyhaline) of the Sundarban mangrove forest. Among the observed micronutrients, Fe content comparatively lower than Cu and Zn. Relatively higher Cu was found in the root of 6 month age Heritiera fomes seedlings grown at the Chandpai (Oligohaline) zone but higher content of Zn was found in the both root and the shoot. At the 9 month age, comparatively higher content of Cu was found in the root of the seedlings grown at the Jungra (Mesohaline) zone but in the shoot, comparatively higher Cu content was observed in the seedlings grown at the Munshiganj (Polyhaline) zone. At the age of 30 months, Cu and Zn both contents found comparatively lower. At the same age (30 months) Fe content was found relatively higher in the root and the shoot of H. fomes seedlings grown at Chandpai saline (Oligohaline) zone but lower in 6-month-old seedlings. At the older age seedlings may appear more metal tolerant/avoider than the younger age seedlings.
