Keanekaragaman Fungi Mikoriza Arbuskula di Ekosistem Gunung Anak Krakatau, Lampung Selatan.
MetadataShow full item record
Anak Krakatau Mount ecosystem was resulted from natural succesion process. Vegetation diversity at the area was studied by several scientists, but simbiotic microbial such as mycorrhizae supporting the vegetation growth was not studied yet. Mycorrhizae is a mutual symbiosis between fungi (mykes) with a rooting (rhiza) plants. Mycorrhizae has spread widely, including in the new ecosystem where succession process occurs. This study aims to identify the genus of Arbuscular Mychorrhizal Fungi (AMF) diversity in the ecosystem of Anak Krakatau Mount, South Lampung. The method used was the extraction of spores using wet sieving and decanting method and centrifugation method, as well as coloring the roots to determine the percentage of colonization. Spore identification to genus level was done using a Melzer solution, while the roots staining was done using trypan blue as dye and PVLG as an adhesive. The results showed that Glomus, Acaulospora, Enthrophospora, Gigaspora and Scutellospora genus was found in the area. Glomus and Gigaspora are genus that found almost in all locations. The highest diversity and spore density was found in coastal vegetation communities while the highest root colonization was found in inland vegetation communities. The abundance and frequency relative of AMF’s spore showed that Glomus was the genus which has the biggest and widest distribution than other genus.
