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

Table 5

Two-way analysis of variance results for soil, leaf, flower, and bioaccumulation of each metal concentration by block and tree type at Tri-Valley Wildlife Management Area, Dresden, OH. Response variables were block and tree type (pure American, BC1F3, and BC2F3). Superscripts indicate required data transformations to achieve residual normality. Dashes (—) indicate levels that were an insufficient sample size for analysis due to concentration levels below detection limit. Asterisks () indicate differences at 0.05 with single asterisk () noting marginal significance.
