Fig. 5.
Shoot P concentrations of EGA Burke and BC3 NILS with large rhizosheath (L) or small rhizosheath (S) grown on (A) an acid ferrosol (pH 4.3) with 250mg kg–1 or 2000mg kg–1 added P or (B) an acid kandosol (pH 4.0) with 50mg kg–1 or 150mg kg–1 added P. Values are means (n=4). For (A) there was a significant interaction between P treatment and genotype and the LSD is shown along with different letters to indicate significant differences (P<0.05) between genotype means and treatments. For (B) there was no interaction between genotype and P treatment and the different letters denote genotypes that differed significantly with P<0.05. For reference, the dashed lines show shoot P concentrations of EGA Burke at low (lower lines) and high (upper lines) P treatments.
