Abstract:
Two soybean cultivars, Z97 (low iron content) and K36 (high iron content), were selected as materials to study the effect of different phosphorus and iron nutrition on the contents of iron and phytic acid as well as the relationships between phytic acid and protein in seeds. The results showed that different phosphorus nutrition had a quite significant affection on the accumulation of phytic acid and iron contents in soybean seeds and the affection extent was different between the two cultivars,and the response trend of the two cultivars to the different iron nutrition level was similar, however, the affection content of K36 was greater than that of Z97. Besides, it was observed that phytic acid content was not correlated with protein and iron accumulation in soybean seeds. In conclusion, it was proved that the main limit factor of iron accumulation were the transport of iron from roots to soybean pods and the translocation from pods to seeds, and the genetic variation of soybean germplasm had a significant affection on the translocation of iron from pods to seeds.
