As part of an investigation of the ways in which supply is related to growth and foliage concentration, and as part of a larger problem of tree establishment on certain polluted soils, seedlings of white pine (Pinus strobus L.) and white spruce (Picea glauca (Moench) Voss) were grown from seed over a 20-week period in nutrient solutions of various Ni and/or Cu concentrations in growth chambers. In one series, Ni was supplied during the latter part of the test period at 0, 0.01, 0.1, 1, and 10 ppm; in a second, Cu was supplied at 0, 0.01, 1, 10, and 100 ppm; and in a third, Ni and Cu were supplied together in factorial combination at 0, 1, and 10 ppm. At the end of each experiment the seedlings were harvested and growth and chemical composition were determined. In general, substantial reductions in growth occurred when concentrations of Ni and/or Cu in the nutrient solutions were greater than or equal to10 ppm. There was some suggestion that white spruce seedlings were more susceptible than white pine seedlings to elevated Ni levels, with the order being reversed for Cu. Foliage concentrations of Ni and/or Cu increased in relation to their concentrations in the external solutions. No definitive trends were evident in foliage concentrations of other elements except Fe and Zn, both of which decreased: Fe in relation to both Ni and Cu supply, Zn chiefly in relation to Ni supply.
