In: Plant and Soil v. 55, no. 1, p. 119-12981-586265Summary: The effects which the osmotic pressures 2.0, 3.5 and 5.0 atm., obtained by the addition of either magnesium sulphate or PEG-4000 to the standard nutrient solution, have on the development and mineral content of Zea mays var. INIA 8302 are assessed. The osmotic effect causes a greater absorption of cations, potassium being the element most readily absorbed. The specific effect of magnesium sulphate causes a decrease in the total of anions and in the water content of the plant and partly offsets the decrease which the osmotic effect produces in the fresh weight
