Change of Sugar Content in Selected Potato Varieties During Storage . Ten Czechoslovakian potato varieties of different vegetation lengths were stored at +2°C and +10°C. Changes of glucose, fructose and saccharose content were examined in the years of 1972–1974. Results show the greatest changes of sugar content to occur in the period of November to January. This period of time is a certain limit in the dynamics of changes of sugar content. Tubers stored at +10°C show a different speed of change of content and share of the various sugars than tubers stored at +2°C. Influence of variety and year of vegetation is clearly confirmed, the influence of the year of vegetation being greater than that of variety. This leads to the conclusion that the physiological state of the tuber also affects dynamics of sugar transformation significally.
