Abstract: Objective: To develop a standard micropropagation protocol for an important vulnerable mangrove Excoecaria agallocha. Methods: Collection of explants, surface sterilization, phenolic exudation and medium was standardized. Shoot induction, shoot multiplication and rooting were carried out in MMS medium supplemented with BAP, Kinetin, Zeatin, 2ip, NAA, IAA and IBA. Hardening was carried out after root well established. Results: The best phenolic exudation removal was resulted in 4 g/L activated charcoal. The maximum shoot induction response showed in MMS medium and better shoot induction was performed in the concentration of BAP (3.9 μmol) and NAA (1.34 μmol). Rooting induction was performed high range at 5.02 μmol of IAA. Well rooted micro-shoots were hardened and acclimatized. Conclusions: From the present investigation, it can be concluded that a standard micropropagation protocol was developed for an important vulnerable mangrove species. [Copyright &y& Elsevier]
