Soybean and G. soja plants were grown in sand culture to study the relationships among nutrient P level, vegetative P concentration, and the phytic acid concentration of the seed. A close relationship between vegetative P concentration during reproductive growth and the phytic acid concentration of seed was observed. Compared to soybean plants, G. soja plants had higher concentrations of vegetative P, paralleling their higher concentrations of phytic acid. Plants grown with nutrient P at 22.4 or 50.0 mg P L('-1) had phytic acid concentrations similar to those observed for field grown plants. Reducing the nutrient P to 2.4 mg P L('-1) resulted in seeds with a greatly reduced phytic acid concentration (4.6 mg g('-1)).
