Abstract
In the terrestrial and aquatic ecosystems the pollution caused by heavy metal accumulation is of major concern. Lead (Pb) is the second most prominent contaminant after arsenic (As). In plants no physiological functioning requires the presence of lead as it is non-essential element. Triticum aestivum L. is one of the major cash crops with high consumption value. The present study enlightened the toxic effect of lead (Pb) on growth regulatory parameters and photosynthetic pigments of test plant in a dose dependent manner. Sterilized seeds were grown under different concentrations of lead acetate salt (800-50 ppm). The result evaluated with reduced germination percentage, retarded root-shoot length and decrease in seed vigorosity as the concentration increases (>100 ppm). The estimation of chlorophyll and carotenoid content also slightly reduced at higher doses of lead salt. Hence, crops cultivated in heavy metal contaminated sites shows poor growth and needs proper monitoring. To overcome this issue, microbial remediation strategies needs to be worked upon along with the application of nanotechnology.
