Abstract
Studies were made to determine factors which influence reconditioning of Russet Burbank tubers. Tubers from plants grown under low fertility were more difficult to recondition than tubers from plants adequately fertilized. Low specific gravity potatoes were also more difficult to recondition than high specific gravity potatoes even though the initial sugar content was approximately equal. The stem portion of Russet Burbank tubers lost considerably less sugars than the bud portion during the reconditioning process. It appears that factors which are responsible for high sugar development are also responsible for difficulty in sugar loss. Results also indicate greater difficulty in reconditioning early in the storage period with the loss of sugars becoming easier as the storage season progressed into spring.
Resumen
Fueron conducidos estudios para determinar los factores que influyen el reacondicionamiento de tubérculos Russet Burbank. Tubérculos de plantas crecidos bajo condiciones de baja fertilidad fueron más difíciles de reacondicionar que los tubérculos de plantas adecuadamente abonados. Papas de baja gravedad específica también fueron más difíciles de reacondicionar que las de gravedad específica alta, aunque el contenido inicial de azúcar fue aproximadamente igual. El tallo de tubérculos Russet Burbank perdió considerablemente menos azúcar que la yema durante el proceso de reacondicionamiento. Parece que los factores responsables de desarrollar alta azúcar también son responsables de la dificultad de pérdida de azúcar.
Los resultados también indican más difficultad de reacondicionamiento temprano en el perído de almacenamiento con la pérdida de azúcar llegando a ser más fácil con el progreso de la campaña de almacenamiento en primavera.
