Short summary
Understanding the electromagnetic properties of plant roots is useful to quantify plant properties and monitor plant physiological responses to changing environmental factors. We investigated the electrical properties of the primary roots of Brachypodium and maize plants during the uptake of fresh and saline water using spectral induced polarization. Our results indicate that salinity tolerance varies with the species and that Maize is more tolerant to salinity than Brachypodium.
