N2 - Changes in the root diameter were measured in wheat, Triticum aestivum L., using a sensor of small displacements in "osmotic experiments," and the hydraulic conductivity (Lp) of the root was calculated by the method of initial flows. The Lp decreased by two to three times during 30-mm exposure m 0.1-9 mM H2O2. In 150 mM NaCl, changes in Lp exhibited two-phase kinetics: an initial increase in Lp by two and a half to three times, followed by a decrease to 1.6-50% of the control level within the subsequent 24 h. After one-day-long exposure of the roots in a solution containing 150 mM NaCl and 100 mg/l catalase, Lp did not differ from the control level. Root pretreatment with salicylate, which promotes the formation of H 2O2, prevented the initial increase in Lp in 150 mM NaCl, probably, due to a drastic Lp decrease. The activity of guaiacol peroxidase in the roots increased by three times within the 20-min exposure of the roots to the salt solution.
