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

Table 2

Eight-year-old chestnut trees (tree types pooled) compared by three ECM categories: those with <25% ECM root colonization (), colonization greater than 25% with black hyphae and sheaths (), and colonization greater than 25% with white hyphae and fungal sheaths (). Error bars are ±1 standard error and different letters indicate statistical differences at 0.05.
