Table 3 Effects of soil P availability (Ps), N deposition rate (Ndep), and their interactions (Ps × Ndep) on component P content of P. edulis seedlings and the fallen leaves (n = 4) indicated by F and (P) values derived from ANOVA analyses. Statistically significant effects (P < 0.05) are highlighted in bold text
