Two-year-old silver maples (Acer saccharinum L.) were grown for 2 weeks in sand culture amended with 5.0 and 20.0 ppm CdCl/sub 2/. A foliar chlorosis induced by cadmium was accompanied by a decrease in foliar iron content whereas zinc content of the leaves was unaffected by cadmium. Foliage in stages of active growth was more sensitive to Cd phytotoxicity than mature foliage. Leaf resistances increased with Cd treatment whereas foliar water contents remained unchanged. Adverse growth effects including reduced stem height and leaf number were observed only where gross root injury was visible at 20 ppm Cd. Reduction in leaf area, fresh and dry weights of the leaves developing during Cd treatment were also noted.
