Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

Heavy metals contamination is a major environmental issue, and phytoremediation is a promising, environmentally friendly alternative to conventional cleanup techniques for heavy metal contaminated sites. In this study, the synergistic enhance effects of melanin with two endogenous antioxidants, viz., glutathione (GSH) and ascorbic acid (SA), on the enhancement of the toxicity tolerance of Cd on Sedum alfredii Hance and its mechanism were investigated by hydroponic experiments. The results showed that, three antioxidant substances enhanced effectively the tolerance abilities of S. alfredii H. to Cd. The decreasing of the induced free radicals and the antioxidant enzymes in the leaves of S. alfredii H. were also observed. Melanin was absorbed directly by S. alfredii H. and participated its antioxidant process under Cd stress.
