The chemical composition of cell wall material obtained from sweet potatoes differing in stages of development, tissue zone and variety was determined. Only minor changes in the composition of the cell wall polysaccharides were recognized with developmental age. On the other hand, the cell wall from the peel was higher in arabinose content and lower in galactose content compared with the cambium and inner-tissue . The neutral sugar compositions of cell walls from 26 varieties of sweet potato were 1.6-2.9% for rhamnose, 3.2-6.0% for xylose, 7.1-11.2% for arabinose, 17.3-30.9% for galactose and 53.4-67.8% for glucose. The galactose to arabinose ratio ranged from 1.83 : 1 to 4.21 : 1 within these varieties.
