The objective of this work was to evaluate physiological changes related to deterioration of sweet potato roots cv. BRS Cuia during storage at room temperature, identifying the major problem during postharvest. It was determined weight loss, sprouts number, sprouts length, water potential, peroxidase and polyphenoloxidase enzymes activities, and fraction of soluble phenols. The evaluated variables showed increases, except for skin fraction of soluble phenols that decreased during storage. Our results indicate that sprouting is the major problem during storage at room temperature; therefore, to optimize this type of storage and to reduce losses, it is necessary to control sprouting.
