Isolation, Identification And Frequency Studies Of Foliar Endophytic Fungi From Dendrobium Sp. And Oncidium Sp

In the present investigation, a total of 47 isolates belonging to 8 genera of foliar endophytic fungi were isolated from two orchids- Dendrobiumsp. and Oncidium sp. They were identified to 8 genera which belonged to the class Ascomycetes (5 genera), Basidiomycetes (1 genera) and 2 sterile mycelium. Dendrobium sp. and Oncidium sp. showed the presence of 4 and 5 genera of endophytic fungal genera respectively. Maximum colonization frequency and relative abundance was shown by Curvularia sp. and Cercospora sp. in Dendrobium sp. and Oncidium sp. respectively. Maximum species diversity was shown by Oncidium sp. than Dendrobium sp. Similarity index of both orchids were also calculated.
