Abstract :The effects of different concentrations of copper on the accumulation, antioxidant enzyme activity, malondialdehyde (MDA), chlorophyll and carotenoid content of Lemna minor, Lemna gibba and Spirodela polyrrhiza L. were investigated. Duckweeds were treated with several concentrations of Cu (0, 10, 25, 50, and 100 µM Cu) for 4 days. According to results, Cu ions were accumulated mainly in L. minor, L. gibba and S. polyrrhiza. The MDA content and proline amount increased with increasing external Cu concentration in duckweeds. However the level of photosynthetic pigments decreased with increasing Cu concentration. Superoxide dismutase and catalase antioxidative enzyme activity increased significantly in plants exposed to 25-50 µM Cu compared to other treatments. These results show that L. minor, L. gibba and S. polyrrhiza can tolerate up to 25 µM Cu treatment.Keywords : bakır, su mercimeği, akümülasyon
