Abstract

Iron uptake and distribution in cucumber root were studied with the help of 57Fe Mössbauer spectroscopy at low temperature applying external magnetic field. Cucumber was grown in iron sufficient modified Hoagland nutrient solution. Mössbauer spectra of the frozen roots taken at 4.2 and 1.5 K, at 5 T external magnetic field support the identification of the main iron species (FeIII-carboxylates, hydrous ferric oxides, Fe III-sulfate-hydroxide) suggested according to its Mössbauer spectra taken between 35-200 K [1]. The magnetic ordering temperature of the hydrous ferric oxide and FeIII-sulfate-hydroxide was found to be in the range of 4.2-1.5 K, which suggests the incorporation of H3O +, PO43- and citrate into these minerals.
