Item Open Access Resistance of Klebsormidium flaccidum (Kützing) Silva, Mattox & Blackwell (Streptophyta) to heavy metals(University of North Bengal, 2009-03) Gaysina, LA; Purina, ES; Safiullina, LM; Bakieva, GRThe influence of copper (1-10-10-2 M/L), nickel (1-10-6-1 M/L) and manganese (Ix10-1-1 M/L) chlorides on morphology of filaments and cells in Klebsormidium flaccidum (Kützing) Silva, Mattox & Blackwell (Streptophyta) were studied. Concentrations of CuCl2 (1x10-5 M/L). NiCl2 (lx10-3 M/L) and MnCl2 (Ix10-1 M/L) caused different morphological aberrations in algal cells, such as granulation, changing of cell form, damage of chloroplast, and complete destruction of the cell content. Heavy metals resulted in a decrease of K. flaccidum filament length. CuCl2 caused increase of the cell length. K. flaccidum aplanospores formation occurred at a MnCl2 concentration of 1x10-1 M/L.Item Open Access Studies on (i) fungicidal and toxicological properties of saligen in cyclic phosphoramido thionates, and (ii) toxicological effects of some pesticides on Algae(University of North Bengal, 1988) Abdul Samad; Das, B K
