Phytic Acid In Developing And Mature Seed Of Soybean (glycine Max (l.) Merr.) And Glycine Soja Sieb. & Zucc. (phosphorus, Zinc, Nutrition)
Soybean {Glycine max (L.) Merr.} and G. soja Sieb. & Zucc. germplasm collections were surveyed for variation in the concentration of the seed phosphorus (P) storage compound, phytic acid. Seed of the soybean lines contained from 13.9 to 23.0 mg g('-1) phytic acid, while seed of the G. soja lines contained from 18.8 to 27.7 mg g('-1) phytic acid. Most of the variation in seed P was due to variation in phytic acid P, with little variation in non-phytic acid P observed among lines within species. High yielding soybean cultivars tended to have the lowest concentrations of phytic acid. Phytic acid was highly correlated with seed protein among soybean lines (r = +0.74). The phytic acid:zinc molar ratio in the seed of the lines surveyed ranged from 26 to 44.
