Evaluation of Free Radical Scavenging Activities Against Multiple Heavy Metals Stress inAvicennia marina(Forsk.) andRhizophora mucronata Lamk
The tolerance mechanism of mangrove species (Avicennia marina(Forsk.) andRhizophora mucronata Lamk) was studied by inducing multiple heavy metal stress in roots and leaves of the plants. Mangrove seedlings were treated with different concentrations of heavy metal solution (Cr, Cd, Pb and Hg...
