Respon Pertumbuhan dan Biomassa Semai Bakau Minyak (Rhizopora apiculata BI) terhadap Salinitas dan Kandungan Lipidnya pada Tingkat Pohon

Abstract

PRAYUNITA. Growth and biomass seedling of Bakau Minyak (Rhizopora apiculata BI) against Salinity and Lipid Contain at Tree Level. MOHAMMAD BASYUNI S.Hut, M.Si, Ph.D dan Dr. Ir. LOLLIE AGUSTINA P PUTRI M.Si. This study aims to see the effect of salinity on the growth bioamassa mangrove non secretion species Rhizophora apiculata in seedling and content of lipid and NSL at tree level. Made with 5 levels of salinity treatments of 0%, 0.5%, 1.5%, 2% and 3% and the seed is planted for 5 months. The results showed the best height and diameter growth of Rhizophora apiculata seedlings at salinity 1.5%, leaf number and leaf area in the salinity of 0.5%. Stem and root biomass best at salinity 1.5%, while the best leaf biomass in the salinity of 0.5%. Total lipid content of the tree Rhizophora apiculata leaves more in the 9.60 mg than in the root is 6.40 mg. NSL content of the tree Rhizophora apiculata NSL roots more in the 0.226 mg than in the leaves is 0.10 mg. This study may provide information to the rehabilitation program in order to obtain Rhizophora apiculata seedlings growing best at different levels of salinity.
