Phytotoxic Effect

The present study assessed the tolerance of Spirodela polyrrhiza (L.) Schleid (giant duckweed) exposed to different concentrations (5% -100%) of chrome liquor for 7 days. Physiological conditions of S.polyrrhizaplants were monitored daily by measuring fresh weight and chlorophyll-a and chlorophyll-b. Fresh biomass of Spirodela plant showed concentration and duration dependent reduction with minimum value (5.71 g) reported on 7 d at 100% tannery effluent concentration. Likewise, significant reduction in chlorophyll-a and chlorophyll-b content wasobserved in concentration-duration dependent manner with maximum reduction reported to be 99.8% and 99.6% respectively on 7 d at 100% effluent concentration in comparison to control.
