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.

ECM morphological categories	Mean % ECM colonization	% ECM range	Chestnut tree height (cm)
<25% colonization	8.4	0–21.3
>25% black morphology	61.2	31–91.3
>25% white morphology	51.0	33.8–84.5
