Absorption and transfer of fe and mn in germinating sorghum

The absorption of Fe from FeSO₄, FeEDTA, and FeEDDHA (ferric ethylenediaminedi (o-hydroxyphenylacetate)), and Mn from MnSO₄, MnEDTA, and MnEDDHA, by germinating sorghum (Sorghum vulgarie Pers. var. M 35-1) was studied. The seeds were found to absorb Fe and Mn from all the sources, and these ions moved to the scutellum, shoot, and root. EDDHA facilitated greater translocation of Fe and Mn from the seed to the shoot and root. The translocation of Fe was more towards the root than to the shoot, whereas it was the reverse in the case of Mn.
