Abstract: Elodea canadensis is a submersed macrophytes, widely distributed in Aquatic environment and able to remove heavy metals from water. This study examines the Cd toxicity on Elodea canadensis.The aim of this research was to study damaging effects of prolonged cadmium exposure on leaves of Elodea canadensis treated for 7 and 14 days with different concentrations of cadmium (0, 10, 20, 40, 80, 160 μM).These effects have been studied by measuring the plant growth, photosynthetic activities and the stress effects in response to cadmium exposure were also investigated by evaluating the levels of some biomarkers (GSH and GST activity).The results obtained show a dose-related inhibition of the growth and decrease of photosynthetic activities of Elodea canadensis compared to the control. We noted also a significant and dose-related increase in GST activity associated with decrease of GSH level .To deal with the cadmium induced oxidative stress, Elodea canadensis activated antioxidant enzymes to diminish the effects of Reactive Oxygen Species (ROS).
Keywords: Elodea Canadensis, cadmium, Respiratory metabolism, photosynthesis, biomarkers.
