We aimed to assess role of cell walls in formation of cation exchange capacity, surface
charge, surface acidity, specific surface, water adsorption energy and surface charge density
of plant roots, and to find the input of the cell wall pectins to the above properties. Whole
roots, isolated cell walls and the residue after the extraction of pectins from the cell walls of
two Apiaceae L. species (celeriac and parsnip) were studied using potentiometric titration
curves and water vapor adsorption–desorption isotherms. Total amount of surface charge …
