The purpose of this research was to identify the structural adaptations in three populations of Convolvulus persicus L. on coastal areas in Mazandaran Province, whose populations of which are severely reducing due to the intense environmental stresses of the coastal zone. In general, annular collenchyma, isobilateral mesophyll, amphiphloic siphonostele, abundant presence of laticiferous tubes, numerous druse crystals and the presence of periderm in rhizome can be introduced as the most important morpho-anatomical strategies utilized against harsh environmental conditions. Sari population was foud to have the most various structural toleration mechanisms in comparison with Babolsar and Nour populations. Few differences were observed in anatomical characteristics in the three populations of Convolvulus persicus as the evidence for high intra-specific phenotypic variability, leading to local adaptation and increase of the tolerability of plants against environmental changes.
