Abstract
Heavy-metal tolerance was investigated in A. capillaris L. (A. tenuis Sibth.) using a standard rooting test on plants originating from a Cu-contaminated site (Parys Mountain) and a Pb-contaminated site (Goginan). Six F1 families obtained by interpopulation hybridization and F2 and backcross generations derived from 1 of them were screened. Estimates of the genetic and environmental components of phenotypic correlation were obtained in terms of both rootlength and tolerance index. Results are discussed in relation to problems of interpretation of evidence for multiple- or co-tolerance based on tolerance indices and phenotypic correlations.Keywords
