Relationship between calcium levels and pectin fractions in potato tubers after storage


Applied Plant Science 7(1): 1-4
Relationship between calcium levels and pectin fractions in potato tubers after storage
Two potato cultivars, Vanderplank and Up-to-date, were grown in and cultured under controlled conditions. The pectin fractions in the tubers of plants receiving nutrient solutions with different calcium (Ca) concentrations were qualitatively and quantitatively determined after 10 weeks'storage at 9-13 degree C. After storage, tubers grown at the zero Ca level had a significantly higher total, water-soluble and water-insoluble pectin content, but a significantly lower versene pectin content than tubers grown at a Ca level of 89.4 mg dm-3. Significant cultivar differences were also found which could be correlated with the keeping quality.
