Soil Metals and Ectomycorrhizal Fungi Associated with American Chestnut Hybrids as Reclamation Trees on Formerly Coal Mined Land

Figure 2

Mean soil (black lines) and leaf tissue (gray lines) concentrations of the six elements (As, Cd, Pb, Al, Cu, and Ag) that differed in concentration from soil to tissue by chestnut tree types (pure American, BC₁F₃, and BC₂F₃) in Dresden, OH, USA (). Soils collected from the reference plots without tree plantings are illustrated as dotted lines on the graph. Asterisks () indicate differences at 0.05.
