To investigate the alleviating effects of zinc (Zn) against gradually increasing cadmium (Cd) stress in aquatic environment, dry weight, polyamines and proline contents as well as metabolic enzymes were studied in Lemna minor L. after 4 days exposure. Dry weight was significantly decreased as the concentration of Cd increased. Cd stress also increased the putrescine (Put) content, while decreasing...
The effects of increasing concentrations of cadmium (Cd) on the ultrastructure, Cd accumulation, generation of O 2− , contents of ascorbate (AsA), reduced glutathione (GSH) and polyamines (PAs), as well as the activities of polyamine oxidase (PAO) (EC 1.5.3.3) and diamine oxidase (DAO) (EC 1.4.3.6) were investigated in the leaves of Potamogeton crispus. Cd exposure resulted in significant...
