Aluminum-Tolerant Pisolithus Ectomycorrhizas Confer Increased Growth, Mineral Nutrition, and Metal Tolerance to Eucalyptus in Acidic Mine Spoil

Table 2

Residual maximum likelihood (REML) results of the influence of Eucalyptus species and Pisolithus isolate source as explanatory factors on plant biomass and mineral nutrition in pot and field trials. The significant fixed effects (nutrients), their standardized estimates with standard error (s.e.), p values, and the amount of variation explained by plant and mycorrhizal parameters are presented.
