Figure 3. Impact of external P supply on seed P composition of a soybean genotype with no low phytic acid alleles (Prichard RR) and of genotypes with either low phytic acid alleles on linkage group L (LG L), or low phytic acid alleles on linkage group N (LG N) or low phytic acid alleles on both LG L and LG N (G03PHY-443) (Experiment 2). LSD_0.05 values for comparison of any two treatment means are 0.56 and 0.22 for phytic acid P and inorganic P concentrations, respectively, as the P level x genotype interactions were significant at the 0.05 probability level. The genotype main effect for cellular P concentration and the P level main effect for total P concentration were significant at the 0.0001 probability level.
