Abstract

Using a spin-echo method to measure the nuclear relaxation time with maize (Zea mays L.) seedlings as the test object, we demonstrate that changes in the magnetic relaxation rate of water that are observed during the disturbance of the hydrodynamic system of root segments by external pressure (up to 4 MPa) are caused by oxygen paramagnetic doping, which, in turn, leads to changes in the permeability of the plasmalemma to water. Atmospheric oxygen is shown to be a significant source of the magnetic relaxation of water in plants.
