Abstract
Sixteen Salix clones of known origin were screened for resistance to c opper in solution culture, using copper concentrations of 0.25, 0.5 an d 0.75 mg l-1 in 25% strength Hoagland's nutrient solutions. Significa nt differences were found in root length increase, number of lateral r oots produced and patterns of metal uptake between species, hybrids an d clones. The potential use of selected willow clones for reclamation and restoration of contaminated soils is discussed.
