Abstract Mangrove forests are one of the most important ecosystems in the tropical and subtropical areas of the coastal regions. Understanding the demographic structure patterns of Mangrove communities is very much needed for conservation programs and rehabilitation and forestry plans. By analyzing the molecular diversity of genetic diversity in poppy populations, Avicennia marina provides a better management of these plant communities to maintain their genetic diversity. Microsatellite markers were used for this purpose. The 4 populations studied (Qeshm, Dough, Tiba and Jask) showed 5 different pairs of microsatellite markers of different levels of polymorphism, indicating that these populations differed from one another. Based on the results, samples of the dough port had the highest heterozygosity. The genetic distance of different populations was also calculated. Accordingly, the greatest difference was observed between the populations of dough and teiban (0.448) and the closest relationship between Qeshm population and dough (0.827). Based on the results, the genetic flow rate among the populations was very high due to their position relative to each other, and this caused the most genetic variation among the populations, not the populations. Based on comparisons with the reports of other researchers from different populations of Iran Avicennia marina, despite the presence on the margin of the region of mangroves, the world has shown a good genetic diversity, which necessitates the protection and protection of these valuable genetic reserves.
