Das Projekt "Rooting Strategy and Heavy Metal Uptake of Metal-Accumulating Plants for Phytoremediation of Contaminated Agricultural Sites" wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Terrestrische Ökologie, Fachbereich Bodenschutz.Extraction of metals from polluted agricultural soils by means of plants is in general limited either by low growth of hyper accumulating plants or low metal-uptake of plants with high biomass production. Moreover, metal-uptake is often much less efficient under field conditions than in pot experiments using the same soils. Rooting strategy was suspected as an important factor for the differences in metal uptake efficiency of different plants and under different conditions of soil structure and heterogeneity. In this project we compared the root growth and metal uptake of hyper accumulators with non- or low-accumulating plants, using agar, model soil and real soil systems.
