Electrical resistances of living shoots of 13 apple rootstocks varying in vigor from very dwarfing to very vigorous were measured. A portable, battery-powered Bouyoucos Model C bridge was used, equipped with needle electrode probes that completely penetrated the bark. Data obtained on shoots of the previous year's growth revealed a direct relationship between the electrical resistance of shoots and the known rootstock effect on scion vigor. Dwarfing and vigorous rootstocks had low and high electrical resistance respectively. When resistance was plotted against time there was a close resemblance to curves for daily periodicity of transpiration.

The entrance of strong electrolytes into Valonia is very slow unless the cells are injured. This, together with the very high electrical resistance of the protoplasm, suggests that they may penetrate largely as undissociated molecules formed at the surface of the protoplasm by the collision of ions. Under favorable circumstances KCl may be absorbed to the extent of 3 x 10–8 mols per hour per sq. cm. of surface together with about 0.17 as much NaCl. Other substances which seem to penetrate to some extent are Li, Rb, Br, BrO3, I, IO3, and selenite. Little or no penetration is shown by SCN, ferricyanide, ferrocyanide, formate, salicylate, tungstate, seleniate, NO2, SO3, Sb, glycerophosphate, and many heavy metals and the alkaline earths. In sea water whose specific gravity had been increased by CsCl cells of Valonia floated for over a year and there was little or no penetration of Cs except as the result of injury. The penetration of NH4Cl decreases the specific gravity of the sap and causes the cells to float: under these circumstances they live indefinitely. It is probable that NH3 or NH4OH penetrates and is subsequently changed to NH4Cl. It would seem that if the sea contained a little more ammonia this would be a floating organism.
