Differential responses of phosphorus accumulation and mobilization in Moso bamboo (Phyllostachys edulis (Carrière) J. Houz) seedlings to short-term experimental nitrogen deposition

Table 2 Effects of soil P availability (P_s), N deposition rate (N_dep), and their interactions (P_s × N_dep) on the component P concentration of P. edulis seedlings and 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
