Summary

Sugar accumulation in potatoes cv Bintje was compared to phosphotransferase activity during cold storage. Mature tubers accumulated reducing sugars and sucrose at an almost linear rate. During storage at 8 deg C sugar accumulation was zero. Sugar accumulation was preceded by a lag phase of approximately 4 days and accumulation of reducing sugars persisted for about 4 weeks, while sucrose accumulation declined after 2 weeks of storage. The ratio of glucose-fructose changed concomitantly with sugar accumulation. Other observations were made.
