“…Variations between cultivars may account for the fact that in cv Desiree ascorbic acid content was not signiÐcantly di †erent between aerial and subterranean tubers while in cv Epicure ascorbic acid concentration was signiÐcantly higher (P \ 0É01) in aerial tubers. A decreased Ñuidity and increased leakiness of cellular lipid membranes has been demonstrated where potatoes were subjected to cold (Shekhar et al 1978 ;Workman et al 1979) however, no di †erences in total lipids between tuber types were recorded in the work reported here. The toxic glycoalkaloid concentration in aerial tubers inhibits their use for direct human consumption or use in the processing industry since glycoalkaloids are not destroyed by boiling, baking, frying or drying even at high temperatures.…”

“…Potato respiration declines with decreasing storage temperature in a special range , but there are differences between tubers with differing resistance to CIS . After 4°C storage, CIS‐tolerant tubers maintained lower levels of RS and higher levels of lactate and ethanol compared with CIS‐sensitive tubers .…”

Cold-induced sweetening (CIS) is critical for the postharvest quality of potato tubers, and the accumulation of reducing sugar is regulated by several metabolic pathways, such as starch synthesis and degradation, hexogenesis, glycolysis, and anaerobic respiration. Starch is the energy source of storage organs, and its metabolism plays an important role in potato CIS. Here, the processes of starch synthesis and degradation in potato tubers and the functions of related genes in potato CIS are summarized, e.g., adenosine diphosphate glucose pyrophosphorylase, starch synthases, branching enzymes, and debranching enzymes for starch biosynthesis as well as a-amylase, b-amylase, amylase inhibitors, and starch phosphorylase for starch degradation. Powerful evidence concerning the relevance of genes related to starch degradation and CIS is described. Moreover, future perspectives in starch metabolic research are discussed.

“…Onaway showed notable changes in glucose and sucrose, where glucose increased while sucrose decreased. Various researchers (Workman et al, 1979;Ewing et al, 1981) have shown that the sugar content of different cultivars responds differently to chilling temperatures. Storage of all tubers at 20°C generally showed slight increases in sugar content (Fig.…”

Two potato cultivars (Kennebec and Simcoe) and one selection (ND 860-2) were stored for 3 months at 4", 9" and 11°C. ND 860-2 had the lowest sugar content at all storage temperatures, produced the lightest colored chips and was the only sample which gave acceptable colored chips directly from 4°C storage. In another study, three potato cultivars (Norchip, Simcoe and Onaway) and one selection (ND 860-2) were evaluated for sugar content and chip color during growth and harvest, two weeks prior and two weeks after foliar senescence, and stored under various time -temperature regimes and upon reconditioning. ND 860-2 generally had the lowest levels of fructose, glucose and sucrose and Onaway had the highest. Storage at 5°C resulted in increases in the three sugars for all tubers, sucrose showing the most notable increase. ND 860-2 was the only sample to consistently produce acceptable colored chips directly from 5°C.
