Abstract
Total sugar, reducing sugar, glucose, fructose, and sucrose were determined in three parts (bud-end, stem-end, and core) of tubers of White Rose, Red La Soda, Kennebec, Russet Burbank, Norchip and Lenape. Tubers were sampled at harvest, after storage for 2 and 4 mo at 7 C, and after reconditioning for 3 wk at 20 C after each storage period. The quantity of different sugar fractions varied with cultivar and changed with storage treatments. Only sucrose was uniformly distributed among the different parts of the tuber. Except for fructose and sucrose the relationships among different parts of the tuber for distribution of all other sugar fractions varied significantly with cultivar, and these relationships among parts were not significantly changed by temperature, or duration of storage.
Resumen
Azúcares totales, azúcares reductores, glucosa, fructosa y sucrosa se determinaron en tres partes (ápice, base y centro) de tubérculos de White Rose, Red La Soda, Kennebec, Russet Burbank, Norchip y Lenape. Los tubérculos fueron muestreados a la cosecha, después de almacenamiento de 2 y 4 meses a 7° C, y después de re-acondicionar por 3 semanas a 20° C después de cada periodo de almacenamiento. La cantidad de las diferentes fracciones de azúcares variaron con el cultivar y cambiaron con los tratamientos de almacenamiento. Solo la sucrosa estuvo distribuída uniformemente entre las diferentes partes del tubérculo. Con la excepción de fructosa y sucrosa las relaciones de distribución entre las diferentes partes del tubérculo de todas las fracciones de azúcares variaron significativamente con el cultivar y esas relaciones entre partes no fueron cambiadas significativamente con la temperatura o con la duraci⤵ del almacenamiento.
