Abstract:

In order to study autecology of Avicennia marina this research has been conducted in Nayband National Marine Park in South of Iran. Fifteen stations have determined at random and three repetitions have been considered at each station and then quantitative and qualitative parameters of the stand have been studied. In order to determine the relation among physical and chemical parameters of water and soil as well as heavy metals of sediments, samples of water and sediments have been taken from the location of stations. The results have revealed that vegetation in most zones enjoys desirable conditions in view of qualitative parameters except stations 6 and 7. There existed positive correlation only between average diameter and acidity and also a negative significant correlation between pH of water and qualitative characteristics of trees (P<0.05). There is no significant correlation between mercury and chromium and basic qualitative characteristics. Nickel has a negative significant correlation with average height and average basic diameter of trees. There is also a negative significant correlation between vanadium and all basal characteristics of grey mangrove. Similar conditions went the same with lead in such a way as there is a negative significant correlation between lead and average diameter of crown, number of trees, average height and average basal diameter (p<0.05). On a whole, one may say quantity of lime, pH of water, completeness of tide and quantity of vanadium and lead has an effective role on growth and quality of the forest stand in the study area.
