    Notes: The influence of sampling and sugar and colour assessment on the correlation between sugar content and fry colour of potatoes was investigated in cv. Record stored at 5 and 10°C (to produce a wide range of reducing sugars), and sampled at the basal, middle and apical region of the tuber.When colour and reducing sugars from adjacent slices were compared excellent correlations were found between these two factors whether the colour was measured objectively, as reflectance density (RD) of the ground paste from fried disks (r = 0.9550) and optical density (OD) of extract from the paste (r = 0.9507), or subjectively against IBVL colour cards (r =−0.9378). Although good correlations were found for individual scorers, using matching colour cards, significantly different regression lines were found between individuals. Reducing sugar levels were generally higher at the basal end than at the apical end. Consequently, the correlations between fry colour and reducing sugars are much poorer if reducing sugar and colour are measured on different tissue in the same tuber and the variation in colour explained by variation in reducing sugar decreased from 90 to 50%.Sampling within tubers thus appears to be a major factor determining the ability to accurately predict fry colour from reducing sugar content. It is suggested that if potatoes for processing are to be rejected on the colour of the darkest part of a tuber then a sample core for sugars should be taken from the basal region of the tuber.

    Description / Table of Contents: Zusammenfassung Änderungen bei Zuckern bei der Sorte Record (der bevorzugten Sorte für Crisps im Vereinigten Königreich) erfolgten während 320-tägiger Lagerung bei 10 °C (einer von Kartoffelverarbeitern bevorzugten Lagerungstemperatur zur Verhinderung von Süsswerden bei niedrigen Temperaturen) entsprechend dem Effekt des Keimwachstums. Beträchtlich höhere Gehalte reduzierender Zucker als im Bereich der apikalen Augen (Abb. 2) konnten während der Lagerung durchweg im Bereich der basalen Augen gefunden werden (Abb. 1). Der Unterschied im Gehalt an Saccharose zwischen beiden Gewebezonen, war nicht so beträchtlich wie bei reduzierenden Zuckern (Abb. 3 u. 4). Zwei Maxima im Gesamtgehalt an reduzierenden Zuckern zeigten sich während der Lagerung (Abb. 1 u. 2), ein initiales maximum, möglicherweise mit dem Abbruch der Dormanz assoziiert, und ein zweites in Verbindung mit kräftigem Keimwachstum (Abb. 5). Regelmässiges manuelles Abkeimen ergab nach anfänglichem Anstieg ein viel längeres kontinuierliches Absinken als in keimenden Knollen, ausserdem verzögerte sich das späte Süsswerden beträchtlich (Abb. 1 u. 2). Dies lässt vermuten, dass Süsswerden anschliessend an den Abbruch der Dormanz möglicherweise vom Keimwachstum bestimmt wird. Allerdings wird auch in derartigem Material, wahrscheinlich entsprechend dem Knollenalter, der Gehalt an Zuckern schliesslich ansteigen.
    Abstract: Résumé Les modifications de la teneur en sucres survenant dans les différentes parties des tubercules au cours de la conservation ont été suivies pendant 320 jours à 10 °C (température utilisée par les transformateurs jour éviter le ‘sucrage’ dû aux basses températures) chez. Record (principale variété du Royaume-Uni pour la fabrication des chips) en relation avec la croissance des germes. Un taux nettement plus important de sucres réducteurs a été trouvé dans les tissus avoisinant l'oeil de la base du tubercule (Fig. 1) que dans ceux entourant l'oeil apical (Fig. 2) tout au long de la période de conservation. La différence en saccharose entre les deux tissus n'était pas aussi marquée que pour celle des sucres réducteurs (Fig. 3 et 4). En ce qui concerne les sucres réducteurs totaux, deux pics ont été trouvés pendant la conservation (Fig. 1 et 2); le premier pic correspond vraisemblablement à la levée de dormance, le second à la croissance vigoureuse des germes (Fig. 5). Un égermage manuel continu conduisait à un abaissement des taux de sucres réducteurs après le premier pic plus long que pour les tubercules non égermés et le ‘sucrage’ final apparissait beaucoup plus tardivement (Fig. 1 et 2), suggérant que le stade de ‘sucrage’ consécutif à la levée de dormance est vraisemblablement sous le contrôle de la croissance des germes. Cependant, dans un tel matériel, le taux des sucres peut éventuellement augmenter sous l'effet du vieillissement du tubercule.
    Notes: Summary Tubers of cv. Record (the major UK crisping cultivar) were stored at 10°C for up to 320 days. Throughout storage, the levels of reducing sugar in the tissue surrounding the basal eye were considerably higher than those round the apical eye but the difference in sucrose between the two tissues was not as marked. During storage, there was an initial peak in total reducing sugar content, possibly associated with the break in dormancy, and a second peak associated with vigorous sprout growth. Regular removal of sprouts caused reducing sugar levels to continue to fall, after the initial rise, for much longer than in spouting tubers and for the final sweetening to be considerably delayed, suggesting that the stage of sweetening subsequent to break of dormancy is possibly under the control of sprout growth. However, even in such material sugars may eventually rise, possibly due to ageing of the tuber.

    Notes: Quantitative studies on the electrophoretic deposition of a polyimide polymer were carried out over the voltage range 25-100 V dc. Deposition yield was related to voltage, time, and coulombs and was found to obey Faraday's laws of electrolysis. Equations relating yield to voltage and coulombs were obtained from the plotted data. Results of coulombic studies indicate that the effective equivalent weight of the polymeric species being deposited is between 6800 and 7500 (i.e., amount deposited per faraday). The coulombic yield is 75 mg per coulomb. Information and speculation on the size and composition of the electroactive species are presented.
