Plants are able to generate electrical responses to various mechanical, electrical, chemical, or light stimuli causing the disturbance of the balance between cation and anion fluxes through the plasma membrane. The aim of the research was to determine the impact of H2O2 (11–20 mM) on activation of ion channels in the plasma membrane of the liverwort Conocephalum conicum. The study was conducted using intracellular microelectrodes. Application of hydrogen peroxide in concentrations higher than 11 mM resulted in vanishing series of action potentials (APs), leading to permanent depolarization of the membrane potential. Potassium channel inhibitor (TEA, 10 mM) and anion channel inhibitor (A9C, 2 mM) caused the suppression of AP series evoked by H2O2.
