Correlation times in rotation diffusion of the radical in leaves and roots of wheat "Moskovskaya 35" were found under different conditions from the ESR spectra parameters of iminoxyl radical 2,2,6,6-tetramethyl-4-oxopiperidine-1-oxyl injected into these objects. The radical was shown to be transported along the plant with water current. Change of viscosity in dehydrated plant was studied. Temperature relationship (in the range 10-35 degrees C) of the probe surrounding in wheat leaves was investigated. A change of stabilizing effect of KCl admixture on the short-range order in water structure of the plants as compared to pure water was found.
