Figure 3. Effect of P supply on P influx (ρmol P/ cm root/ second) for safflower and sunflower in sandy (A) and loamy (B) soil. For a given species and a given soil type, means within each column followed by the same capital letter are not significantly different. * indicates significant difference between columns at the same P level. P< 0.05, n=3
