Pengaruh Salinitas terhadap Pertumbuhan dan Biomassa Semai Non-Sekresi Ceriops tagal dan Kandungan Lipid pada Tingkat Pohon

Abstract

RAMAYANI: Effect of salinity on growth and biomass of Semai Non-secretion of Ceriops tagal And Lipid Content in the tree, guided by MOHAMMAD BASYUNI and LOLLIE AGUSTINA P. PUTRI . Effect of salinity on seedling growth and biomass of non-secretion of C. tagal and lipid content in the tree. The research was conducted in the greenhouse, Faculty of Agriculture and Pharmaceutical research laboratories, Faculty of Pharmacy, University of North Sumatra from July 2011 to July 2012. The goal is to determine the level of growth and seedling biomass C. tagal at different levels of salinity, knowing the lipid content in leaves and roots of C. tagal at tree level. Studies using the 5 treatments, namely salinity 0%, 0.5%, 1.5%, 2% and 3%, with five replicates each. Lipid extraction and analysis performed by extracting the leaves and roots of mature trees taken from the mangrove forest Pulau Sembilan. The results showed seedling C. tagal with different levels of salinity give real effect to height, diameter, and seedling biomass. Seedling growth of C. tagal best there is at 0.5% salinity with high growth and seedling diameter is 3.24 cm and 3.65 mm. Wet weight and dry weight of leaves, roots and stems of seedlings with C. tagal the highest at 1.5% salinity. Total lipids in leaves and roots of trees are C.tagal of 16.2 mg and 8.9 mg.
