EPR Study of Accumulation and Toxic Effect of Iron and Copper During the Development of Solanum Tuberosum L. in Vitro
Journal of applied spectroscopy(2022)
Abstract
The migration and accumulation of iron and copper ions during the growth of Solanum tuberosum L. vial potatoes were studied. The speciation and content of the metals in the tissues of potatoes grown under factorostatic conditions were determined by elemental analysis and electron paramagnetic resonance (EPR). The toxic effect of the studied heavy metals manifested in the physicochemical characteristics (change of EPR signals and metal accumulations in plant organs) and biometric parameters as the contents of metal salts in the nutrient medium increased. The EPR spectra also showed a narrow singlet typical for stable semiquinone radicals.
