ABSTRACT
Supplementation of paraquat into the culture medium proved to be highly toxic for a blue-green alga Cylindrospermum sp. A concentration of 15 microg/ml proved algicidal for the test alga. Various concentrations (0.5 microg/ml - 15 microg/ml) of the herbicide affected the growth and reduced chlorophyll and phycocyanin contents of the alga. In addition, it inhibited differentiation of heterocysts and akinetes. The inhibition of algal growth was found to be partially relieved on addition of 500 microg/ml of glucose.
