Biodiversity of Cyanophycean Members from Paddy Fields of Khazan Lands

Abstract

Survey of paddy fields situated in the areas with constant influx of salt water, commonly termed as khazan lands recorded 84 species of cyanobacteria belonging to 16 different genera. The species recorded were unicellular, heterocystous and non-heterocystous. Among the non-heterocystous forms genus Oscillatoria  was maximum as compared to others. This is followed by heterocystous forms like Anabaena, Calothrix, Nostoc, Lyngbya, phormidium, Chroococcus, Aphanothece, Scytonema and other unicellular genera like Microcystis, Gleocapsa, Spirulina and Cylindrospermum one each.
