ABSTRACT:Hyperaccumulator plant, Solanum nigrum L. was exposed to different concentrations of cadmium (Cd) such as 10 mg/kg and 50 mg/kg of soil. The results revealed that concentration of Cd reduced plant growth attributes such as shoot length and root length in a dose-dependent manner as compared to control. The reduction of growth attributes was significant (< 0.05) at 50 mg/kg of soil as compared to 10 mg/kg of soil and control. Application of Cd also reduced the chlorophyll contents, fresh and dry biomass significantly (< 0.05) as compared to control. The assessment of Cd accumulation in shoot and roots through inductively coupled plasma mass spectrometry (ICPMS) analysis showed that a higher concentration of Cd was accumulated in roots as compared to shoot. The study concluded that S. nigrum has potential to be used in Cd-contaminated marginal land for phytoremediation.
