Ecological Preference of Soil Texture to Distribution of Mangrove Seedling Species in the Forest Mangrove Teluk Buo, Padang-Sumatera Barat

Abstract

A research has been conducted to find out the ecological preferences of soil texture on seedling of mangrove species in mangrove forest of Teluk Buo, Padang of West Sumatra. The study was done from May to July 2008. Samples were taken by making 3 transect lines perpendicular to the coastline. 26 observation plot 10 x 10 m was placed continuously zigz zag left to right along the transect line. In each plot is recorded the species of seedling were found and soil texture. Soil texture analized in the lab. Biology FMIPA-UNP. The study revealed that there is an ecological freferences the soil texture to the distribution of seeding of mangrove species. The seedling of Rhizophora apiculata, Ceriop tagal and Sonneratia alba was collected in areas with dusty clay soil texture. The seedling of Avicennia marina was collected on sandy loam soil and sand. The seedling of Bruguiera gymnorhyza only present on the clay sandy soil.
