Fig. 1. Graph of seed content of (A) total P, (B) inorganic P, (C) phytic acid P, and (D) non-phytate P for four barley lpa genotypes, and Harrington from 2 yr. Expressed as µg P seed^–1 over three dates during development and at maturity. P determinations as described in Materials and Methods. Data points and standard error bars represent means for two reps from three sib-selections of each lpa genotype, and two reps for Harrington.
