The ability of different willow cultivars to survive and adapt to contamination in polluted soils can vary according to the nature and concentration of the contaminants. A study was undertaken to identify which cultivars had the highest yields, and to determine whether the origin of the cuttings influenced survival, growth, and phytoextraction potential of willow cultivars grown on polluted soil. Survival, growth and phytoextraction of trace elements (Cd, Cr, Cu, Ni, Pb, Zn) were compared for 10 willow cultivars planted in a highly organics-contaminated industrial environment versus in an uncontaminated control. Variations in cultivar response according to cutting origin (contaminated site or not) were also analyzed for each site. The results of the study could help build more effective phytoremediation protocols for highly contaminated environments by identifying willow cultivars and cutting selection techniques appropriate for specific environments.
