Figure 3. Effect of P supply on root radius (A, µm) and specific root density (B, cm root/ g root) of wheat (Anbar, Kahhatat, and Noursi). For a given wheat cultivar and different P supply, means followed by the same capital letter are not significantly different, means of the same P supply within cultivars followed by the same small letter are not significantly different. P< 0.05, n=4
