VAM AND DARK SEPTATE ENDOPHYTIC FUNGI IN A TROPICAL DRY

PRIYANGANA TRIPATHI

ABSTRACT:

Vesicular arbuscular mycorrhizal colonization and spore density was studied in 12 forest plants collected from Tropical Dry Deciduous Forests of Sagar (M. P.). Root and rhizosphere soil samples collected from forest plant species and analysed for quantitative and qualitative study of VAM Fungi and DSE. VAM spores were isolated and their quantitative estimation was done. We observed three mycorrhizal types including Arumtype, Paris-type, and an intermediate type among the plants. Another type of potentially beneficial fungi associated with roots of nine species was also observed, namely, dark septate endophytic fungi (DSEF). Of the 12 sample plants examined, nine species were co occurred by the two target fungi (Vesicular Arbuscular mycorrhizal fungi (VAMF) and DSEF). Maximum VAM colonization was observed in Tectona grandis and minimum in Albizia lebbek Benth. Based on this investigation, we speculated that the DSEF are ubiquitous in forest ecosystems and can co-occur with VAMF in forest plants, functioning much like VAM fungi. Further studies will be required to elucidate interactional mechanisms with VAMF and the mechanisms operating in forest ecosystem.
