RAFFLESIA MEIJERII IN TELE PROTECTED FOREST OF NORTH SUMATERA
The researches aimed to Analising species vegetation and importan value indeks of all species in inventory plot area as habitat Rafflesia meijerii and analysing the physics site area and relationship community of life between Rafflesia meijerii and Tetrastigma sp was done in reserve forest area on West Pakpak District of North Sumatera. Data collection was received by inventory of 15 plots area of 20 m x 20 m (0.60 ha). Based on inventory data collection was obtained imformation about vegetation and the relationship of Rafflesia meijerii and Tetrastigma sp. Based on the result of analysis data was conlused that there are 8 species vegetation in inventory plots area and the important value indeks of all species were sugar wood kayu (Cinnamomum ummiverum, IP = 170.34 %), hapas-hapas (Exbucklandia populena IP = 163.120 %), medang (Endospermum malaccensis IP = 6.6735 %), laban (Vitex negundo IP = 27.474%), simartolu (Schima wallicii IP = 64.205 %), tusam (Pinus merkussii IP = 9.321%), anturmangan (Casuarina sumtrana IP = 8.331%), and hotting (Lithocarpus cycloporus IP = 15.192). Based on data analysis that it can be conclused that it obtained one life form as a community plant between spesies of Rafflesia meijerii and Tetrastigma Sp much discovered in under cover of tusam (Pinus merkussii) species and this case can be hipotized influencing of mikoriza at roots and setup the growth of tubers.
