A series of studies were conducted to better understand the occurrence and causes of internal necrosis (IN) in ‘Covington’ sweetpotato (Ipomoea batatas). Assessment of the problem among the industry was done for 2 years and revealed that IN was widespread in commercial storage facilities throughout the state of North Carolina; both incidence and severity were generally low (<10% incidence with minimal severity of symptoms). A few storage rooms had a high percentage of INwith severe storage root…

Effects of Preharvest and Postharvest Treatments on Incidence and Severity of Internal Necrosis in ‘Covington’.
Of the factors tested, temperature conditions during storage the first two weeks after harvest appear to be highly influenced in subsequent IN incidence, with lower temperatures and shorter durations significantly reducing IN occurrence in ‘Covington’ sweetpotato.
Influence of Herbicides on the Development of Internal Necrosis of Sweetpotato
The presence of IN affected roots in nontreated plots indicates that some other pre- or post-curing factors other than herbicides are responsible for the development of IN, however, the ethephon application prior to sweetpotato root harvest escalates theDevelopment of IN.
Internal defect scanning of sweetpotatoes using interactance spectroscopy.
It is demonstrated that interactance spectroscopy can detect the unique near-infrared optical signatures of necrotic tissues in sweetpotatoes down to a depth of approximately 5±0.5 mm and that light scattering measurement methods will represent a significant improvement over the current destructive analysis methods used to assay for internal defects inSweetpotatoes.


Preharvest Foliar Applications of Ethephon Increase Skin Lignin/Suberin Content and Resistance to Skinning in Sweetpotato Storage Roots
Skinning or surface abrasion in sweetpotato [Ipomoea batatas (L.) Lam.] roots during harvest causes a substantial loss of marketable products in storage as a result of rots, loss of moisture, and
