| Inhoud: |
Maize seedlings treated with various concentrations (25-100 μM) of copper for 15 days. A progressive decrease of root length and biomass with increasing Cu in nutrient solution was observed. The roots accumulated significantly higher amounts of Cu than the above ground parts. Accumulation of copper resulted in more active lipid peroxidation in both roots and shoots, which was attributed to copper-induced additional oxidative stress. Activities of APX (ascorbate peroxidase), GPX (guaiacol peroxidase), GR (glutathione reductase) and CAT(catalase) were higher in both roots and shoots in response to copper accumulation. Changes in lipid peroxidation and antioxidant enzyme activities suggest that oxidative damage may be involved in copper toxicity. |
