Abstract: | Summary The penetration of the dye, dahlia, into the sap ofNitella has been determined in the presence of NaCl, KCl, MgCl2 and CaCl2 at various concentrations.NaCl is the least effective and MgCl2 was the most effective in preventing penetration of the dye.It was found that NaCl antagonizes the action of CaCl2 in certain proportions to a small degree but not sufficiently to permit the dye to penetrate at a normal rate.Published by permission of the Surgeon General. |
