Descripción
Ni accumulation and concomitant physiological and biochemical responses were studied in Eichhornia crassipes1 exposed to different concentrations (1, 2, 3 and 4 mg l−1 Ni) for 72 h. E. crassipes1 rapidly sorbed Ni during the first 24 h. Ni concentration in roots was significantly higher than in aerial parts. Continuity of the photosynthetic activity was observed by a significant increase of pigment concentrations during the first 48 h, followed by a decrease at 72 h. In aerial parts, MDA concentration increased significantly during first 48 h at the highest Ni concentration exposure. However, was evidently counteracted by the compensatory protective mechanism of increased antioxidant enzyme activities. In roots, a significant increase in enzyme activities of antioxidant system did not prevent lipid peroxidation observed by an increase in MDA concentration at 72 h of exposure. Our results suggest that E. crassipes1 was able to tolerate Ni stress increasing the activity of its antioxidant system at short exposure times and low Ni concentrations studied.
