Cyanobacterial association on the roots of epiphytic orchids

The present study is the first report on species level taxonomic enumeration of orchid associated cyan obacteria. Various cyan obacterial species were recorded from the aerial and substrate roots of epiphytic orchids. Aerial roots are having more cyanobacterial population than substrate roots of epiphytic orchids. A total of 10 species of cyanobacteria belonging to 4 families (Chroococcaceae 1; Oscillatoriaceae 4; Nostocaceae 1; Scytonemataceae 4) were recorded. Detailed taxonomic descriptions and microphotographs are also provided.
