Fig. 4.

Shoot P content (total P accumulated) in shoots of EGA Burke and BC₃ NILS with large (L) or small rhizosheaths (S) grown in (A) acid ferrosol (pH 4.3) with 125mg kg⁻¹ or 2000mg kg⁻¹ added P or (B) acid kandosol (pH 4.0) with 50mg kg⁻¹ or 150mg kg⁻¹ added P. Values are means (n=4) and different letters indicate significant differences (P<0.05) between genotype means (no interaction between genotypes and treatments). For reference, the dashed lines show shoot P content of EGA Burke at low (lower lines) and high (upper lines) P treatments.
