The effect of different concentrations of NaCl, Na2SO4, MgCl2 and MgSO4 on the growth in length of the first seminal root of corn, and on the change in dry weight of the whole seedling and its separate parts was studied. The effect of mannitol was also investigated for comparison and to study the osmotic effect. The effect of salts on root growth was dependent on the salt species; all effects were specific for the ions investigated, not due to osmotic activity of the solution. The growth of corn roots was suppressed by concentrations of salts much lower than those required to suppress germination
