Abstract:
The experiment was designed to check the metal tolerance capacity by using different concentrations i.e., 0ppm, 2ppm, 4ppm and 6ppm of nutrient cadmium chloride and copper sulphate solutions. Various physico-chemical parameters like pH, EC and TDS were observed in the concentrations. The high value of pH, EC and TDS was found in the highest concentration of nutrient solution. These plants were grown in different concentrations of nutrient solution for 15, 30 and 45 days. Morphological parameters like root length, leave length, dry weight, fresh weight and number of leaves were also observed. Best metal uptake was observed in 6ppm nutrient solution while in control less uptake of metals was observed. The maximum root and leave length were found in case of control concentration because having no salt. The excess amount of metals reduced the growth parameters. Therefor minimum growth was observed in 6ppm nutrient solution. Order of metal uptake was Cd > Cu. Uptake of Cd was higher than Cu. Roots accumulated highest amount of heavy metals than leaves because it was completely submerged into nutrient solutions. Translocation factor of Cadmium and Copper was less than 1. The purpose of this study to evaluate the effect of heavy metals on the growth parameters of plant Pistia Stratiotes in different concentration of nutrient solution.
