Abstract
The aim of the study was estimation of the influence of reconditioning of tubers of some potato cultivars on the content of reducing sugars and determination of relationship between the levels of the reducing sugars after harvest and after reconditioning. Tubers of the cultivars Finezja, Flaming, Jelly, Oman and Wiarus were stored at 3°C and reconditioned at 15°C for 7 and 14 days. The reducing sugars content was determined after harvest and after 3 and 7 months of storage. In all cultivars concentration of the sugars was low after harvest and increased in storage. The highest effect of reconditioning on decrease of the reducing sugars concentration was observed in the cultivars Flaming and Jelly, independently on the storage time or duration of the reconditioning treatment. A significant positive correlation (r = 0.90) has been stated between the levels of the reducing sugars after harvest and after reconditioning.
