Influence of Magnesium, Potassium, and Nitrogen Nutrition on Phosphoenolpyruvate-Stimulated Carbon Dioxide Fixation¹

N. T. Coleman

W. A. Jackson²

Synopsis: Homogenates from leaves of sweet potato plants grown in solutions low in K, Mg, and N were found to have a reduced capacity to fix CO₂ in the presence of phosphoenolpyruvate. Addition of Mg to the assay restored activity to Mg-deficient leaves, but addition of K to extracts from K-deficient leaves did not.
