The resistance of potatoes to low temperatures.Peer-reviewed article

V. DOBROVÁ-ZÁRUBOVÁ

The author followed critical temperatures with respect to freezing point in some typical Czechoslovakia sorts of potatoes and came to conclusion, that 1. the freezing point is almost constant and characteristic for every sort. 10 examined sorts of potatoes showed to have the freezing point within the limits of 1.09 to1.90 °C. 2. The differences in critical temperatures depend neither on water content, nor on the size (weight) of potatoes. 3. The differences in freezing points correspond to those in osmotic pressure of cells. 4. The resistance of potatoes to necrose of tissues caused by low temperature is in relation to the freezing point and direct relation to osmotic concentration.
