TABLE 4.

Results of three-way ANOVA for factor competition (1–5), mycorrhization (NM, AM), and fertilization (control, +N, +P) on tissue phosphorus, tissue nitrogen, RNE and RNE-P of T. subterraneum and L. multiflorum.

Data stated are P-values, with significant effects (P < 0.05) given in bold. Different letters for factor fertilization, or the interaction of mycorrhization × fertilization indicate significantly different means (Tukey’s HSD post hoc, P < 0.05).
