Keanekaragaman Fungi Mikoriza Arbuskula pada Tegakan Karet dan Tegakan Sawit di Ekosistem Lahan Gambut Desa Telaga Suka Kecamatan Panai Tengah Kabupaten Labuhan Batu

Abstract

Peatland rehabilitation can applied with mycorrhyza, if data and isolate of mycorrhyza in that peatland have been knowed. For that a study have been conducted to determine the diversity and density of spores of Arbuscula Mycorrhiza Fungi (AMF) in rubber stands and oil palm stands in peatland ecosystems in Desa Telaga Suka, Kecamatan Panai Tengah, Kabupaten Labuhan Batu. Observations and analysis performed in Laboratorium Biologi Tanah, Fakultas Pertanian while trapping of AMF conducted in Rumah Kaca, Fakultas Pertanian. The observations parameters used were spore density, degree of root colonization, and the identification of spores type. Results showed that the average density of AMF spore isolation results from the field, in rubber stands 25/10 gr of soils, and in oil palm stands 37/10 gr of soils. The average density of AMF spores trapping method results in rubber stands 161/10 gr of soils and in oil palm stands 242/10 gr of soils. FMA type contained in the study site is the type of Glomus spp. and Acaulospora spp.. The average colonization of roots in both stands is low.
