In: Zagazig Journal of Agricultural Research 2002.v.29(4)Summary: The present study aimed at evaluating the capacity of three selected plant species i.e .Luffa aegyptiaca, Brassica napus and Hibiscus cannabinus, to accumulate and tolerate cadmium. The three plant species were planted under different treatments of cadmium (0, 25, 50, 100, 200, 400 and 800 ppm), after 150 days Cd concentration was determined in roots, stem and leaves of each species. Soil Cd was also determined in two forms; total and chemically extractable . The results of this study revealed that: From the three plant species used ,L aegyptiaca accumulated higher amounts of Cd compared to B. napus and H. cannabinus. Roots accumulated more Cd compared to stem and leaves. The results recommend the cultivation of L. aegyptiaca in soils contaminated with cadmium for its phytoremediation.
