Tolerance and accumulation of lead by fenugreek

Abstract

In the present study, the response of fenugreek (Trigonella foenumgraceum L.) along with remediation potential was tested against lead (Pb). A pot trial was set up in order to evaluate remediation efficiency of T. foenumgraceum. Growth parameters and remediation potential of fenugreek against different concentrations of Pb was compared. Different physical parameters were studied. Biochemical parameters like chlorophyll content, soluble protein, total soluble sugar and proline were analyzed. The results showed that fenugreek accumulated Pb and translocated it in the harvestable parts of the plants. Metal accumulation increased consistently with increasing concentration of Pb in the treatments. Dry matter yield of plant increased with decreasing Pb concentration in the treatment. In conclusion, fenugreek can be used for remediation of Pb contaminated soil.
