Résumé : The calcium in the normal artificial pond water (A.P.W.) for Chara australis was replaced by magnesium and the resulting changes in resting potential, action potential, and ion permeabilities were measured. The effect of lowering the pH of the A.P.W. from 6.5 to 4.5 in the presence of either Ca or Mg was also observed. It was concluded that ionic permeability changes induced by varying the pH are Ca or Mg mediated and the ionic permeability changes occuring during an action potential can be mediated by Ca but not by Mg. © 1970 Oxford University Press.
