HYPER ACCUMULATION OF CADMIUM IN SOLANUM NIGRUM L. AND THEIR EFFECTS ON PHYTO-CHEMICALS AND ANTIOXIDANT ENZYMATIC ACTIVITIESAbstract
In the pot experiment, Solanum nigrum L. treated with different concentration of Cd showed high accumulation of Cd in plant. Growth of plant was not significantly affected up to ≤ 50ppm Cd treated plant, The trends of Cd accumulation in plant were leaf>shoot>root with increasing concentration of Cd and DAS. Plant accumulates 298, 92 and 58 ppm of Cd after 60DAS in leaf>shoot>root respectively, at 50ppm Cd treatment. Solasodine and proline content was increased at ≤ 40 to 50 ppm Cd treated plant, while APX and CAT activity showed the survivability against Cd toxicity up to ≤ 60ppm of Cd. Qualitative phytochemical analysis viz. alkaloids, tannins and flavonoids were dominant at early days and unaffected up to ≤30ppm Cd treated plant. BF and TF for was >1.0 for Cd in Solanum nigrum L. hence the Cd accumulation capacity of the Solanum nigrum L. could make it useful for phytoremediation of the metal.
