Average values of resting potential (RP) and parameters describing the electrically evoked action potentials in Marchantia polymorpha thalli in the control plants and after the treatment with 20 µM verapamil, 20 µM tetrandrine, and 75 µM NED-19. Asterisks indicate statistically significant difference (p < 0.05).
