Fig. 3.

N and P accumulation rate and partitioning into leaves, stems, roots and nodules as influenced by nitrogen supply (LN and HN) and microbial symbiotic association (N, NM, NR and NMR). Vertical bars represent s.e. (n = 4) of the means. Different letters indicate significant differences assessed by the Tukey HSD test (P < 0·05) after performing two-way ANOVA with residual estimation. N and P accumulation rate (mg plant⁻¹d⁻¹) represents an average rate of accumulation calculated as (T₂ amount − T₁ amount)/9 d.
