Facilitation of American Chestnut (Castanea dentata) Seedling Establishment by Pinus virginiana in Mine Restoration

Table 4

Nutrient and metal concentration (±1 SE) from a subsample of seedling leaf tissue between chestnuts colonized by Scleroderma (+) to those found without (–) sampled 18 months after planting (𝑛=26). Asterisk (*) indicates significant differences. ECM plants had significantly lower Ca (%) and Cu (ppm). Analyses based on data transformation by Log (𝑛+1).
