Item Open Access Response of Westiellopsis prolifica Janet. and Scytonema cincinnatum Thuret ex Born et Flah. (Cyanobacteria) to the effect of 2,4-D on growth and nitrogen fixation(University of North Bengal, 2009-03) Shamina, M; Madusoodhanan, PVEffect of different concentrations (0.5-100 mg.ml-1) of 2,4 - Dichlorophenoxy acetic acid on the growth of the cyanobacteria Westiellopsis prolifica Janet and Scytonema cincinnatum Thuret ex Born. et Flah. has been studied. 2,4-D stimulated the growth up to 5 mg.ml-1 in W. prolifica and up to 1 mg.ml-1 in S. cincinnatum respectively over the control. Higher concentration of 2,4-D (above 10 mg.ml-1) proved lethal for both W. prolifica and S. cincinnatum, even though it could tolerate up to 100 mg.ml-1.
