| Description |
Salicornia brachiata (Amaranthaceae) plants were treated with three different heavy metals, CdCl2 center dot H2O, NiCl2 center dot 6H2O and NaAsO2, in the presence of 200 mM NaCl to study their role in metal tolerance. The plants could tolerate up to 300 mu M Cd2+, 200 mu M Ni2 + and 100 mu M As3 +. There was no significant difference in plant fresh weight. All the treatments adversely affected the chlorophyll content of the treated plants. Accumulation of Cd2+, Ni2+ and As3 + in foliar tissue was found to be significantly higher in all the treatments. Proline content was increased significantly in all the treatments except in 50 mu M Cd2+. H2O2 content showed gradual increase with the increasing metal concentrations. The catalase (CAT) activity was significantly increased following exposure to all three metals, whereas superoxide dismutase (SOD) activity was significantly higher at maximum concentration of Cd2 + and Ni2 + treatments. This study suggests that Salicornia plants can be a good source for the phytoremediation of heavy metal polluted saline coastal areas.
