Figure 1. Influence of P supply on seed P composition of normal and low phytic acid soybeans (Experiment 1). LSD_0.05 values for comparison of any two treatment means are 0.42, 0.32, and 0.37 for phytic acid P, inorganic P, and total P concentrations, respectively, as P level x genotype interactions were significant. Genotype and P level main effects on cellular P concentration were also significant at the 0.0001 probability level.
