Abstract
The migration and accumulation of manganese ions during the growing season of Solanum tuberosum L. potatoes have been studied. The complex form and content of the metal in potatoes cultivated under factor-static conditions are determined using elemental analysis and electron paramagnetic resonance (EPR) technique. The toxic effect of the metal manifests itself in biometric indicators with an increase of manganese salt content in the nutrient medium, which is accompanied by growth of the EPR signal and the accumulation of metal in plant organs. In addition, the EPR spectra show a narrow signal characteristic of stable semiquinone radicals.
