SUMMARY Zinc uptake by a range of zinc‐tolerant and non‐tolerant populations of Silene maritima was studied by means of long‐term water‐culture experiments. The pattern of zinc uptake and transport in mine populations differed from coastal and arctic‐alpine populations. All mine populations showed some degree of restricted transport from root to shoot; some also accumulated zinc in the roots. Uptake characteristics could be correlated with soil zinc analyses but did not relate directly to indices of zinc tolerance obtained by short‐term measurements of radicle elongation.
