Effect of various concentrations of chromium polluted soil on biochemical changes of Globe amaranth (Gomphrena globosa L.)

An attempt was made to study the effect of different concentrations of chromium on biochemical specifications on response of Globe amaranth (Gomphrena globosa L.). The seeds were obtained from Private Agro centre, Villupuram District, Tamil Nadu, India. The healthy seeds of globe amaranth were chosen and used for both laboratory experiments. The various Cr concentrations were used (25, 50, 75 and 100 mg/l). Biochemical parameter such as, protein, amino acid, sugar and proline contents in leaf, stem and root of globe amaranth at 15, 30, 45 and 60 DAS in chromium polluted soil. Among the results protein, sugars and amino acid contents in leaf, stem and root were also significantly decreased in all different concentration of Cr treated as compared to control plants. On the other hand, proline content in leaf, stem and root were increased in all the Cr treated plants as compared to control. To sum up protein, sugars and amino acid were also significantly decreased while, proline content was increased in all the chromium treated plants.
