Identification and Abundance of Indigenous Endomycorrhiza Isolated from Nickel Post-Mining Plantation in Sorowako

Endomycorrhiza or arbuscular mycorrhiza has received tremendous attention due
toits ability to form a mutualistic symbiotic with 80-96% of plant species.
Therefore, the objectives of this study were to identify and to determine the
abundance of indigenous endomycorrhiza spores isolated from the nickel post�mining plantation area in Sorowako. Quantitative-qualitative research was
conducted in two stages, which were; (1) Rhizosphere sampling of Morus alba and
Cyperus rotundus at nickel post-mining in Sumasang 1 area, rhizosphere of Wedelia
trilobutu and Melostoma affine in Sumasang 2 block A area, rhizosphere of Gleichenia
linearis and Equisetum gigatum in Sumasang 2 block B area, Sorowako village, East
Luwu Regency, South Sulawesi Province, Indonesia; (2) Isolation and identification
of spores Glomus sp., Acaulospora sp., and Gigasporas sp. were performed at the
Microbiology Laboratory, Research and Development Center for Environment and
Forestry Makassar, South Sulawesi.Based on the results, it had been found 41.6-
63.6% Acaulospora sp. spores with two layers of spore wall and average diameter of
71.6μm; 26.6-50.0% Gigaspora sp. spores with one layer of spore wall and average
diameter of 232.7μm, and 8.3-13.3% Glomus sp. spores with hypha remnant to
spore wall and average diameter of 85μm in Sumasang nickel post-mining
plantation area
