Mangrove root systems have evolved into distinct morphological forms that addios both problems consideraneously.

Salt Management: Excretion, Exclusion, andAccumulation

Te salinity of seawater averages approximately 35 parts per texand, and tidal looding regularly expose mangrove roots to salt concentrations that would cause water to leafe plant cells by osmosis. Mangroves employ three principal strategies to cope with this osmotic stres: salt exclusion, salt exction, and salt accumulation. Many species combinane more than one approcompact.
