dc.description.abstractThe potential of a wild, unpalatable plant Coronopus didymus was investigated for the first time in terms of its capability to tolerate and accumulate cadmium (Cd) for phytoremediation purposes. A screenhouse experiment for 6 weeks was conducted to evaluate the effect of Cd from 100 to 400?mg?kg?1 on growth, biomass, photosynthetic apparatus, Cd uptake and accumulation in C. didymus plants. Application of Cd facilitates the growth of the plants whereas at higher levels a slight reduction was noticed. The concentration of Cd in roots and shoots reached a maximum of 867.2 and 864.5?mg?kg?1 DW respectively, at 400?mg?kg?1?Cd treatment. Cd exposure increased the generation of superoxide anion (O2??), H2O2 content, MDA level and antioxidative response (SOD, CAT and POD) in roots and shoots of C. didymus. However, a slight decline in SOD and CAT activities were noticed in roots at highest Cd treatment (400?mg?kg?1). The bioconcentration (BCF) values for all the concentrations were ?1 and the translocation factor (TF) values were ? 1 at lower level but reached 1 at highest Cd concentration. Thus, C. didymus satisfies the conditions required for hyperaccumulator plants and may be practically employed to alleviate Cd from contaminated soils. ? 2016 Elsevier Inc.en_US
