impact of growth promoters on the growth of two cyanobacteria (nostoc entophytum and hapalosiphon stuhlamanii)

The present investigation emphasizes the effects of Gibberllic Acid and Kinetin on growth of blue-green algae Nostoc entophytum and Haplosiphon stuhlmanni. Individual application of both growth promoters showed a marked stimulation of fresh weight and chlorophyll-content at all concentrations on these blue-green algae. Interaction of Gibberllic acid and Kinetin on both algae noticed with increasing concentration has synergistic response on growth of N. entophytum and H. stuhlmanni
