“…Furthermore, the association was supported by the results of experiments conducted with 17 cultivars from different regions of the world, whose dry matter content ranged from 17.9% to 31.2% [60]. However, 'Apomuden' (19%) and 'Nane' (27%), two cultivars with low and high dry matter content, showed no significant difference in their wound healing ability [61].…”

Sweet potato (Ipomoea batatas (L.) Lam.) is served as an important root crop worldwide due to its high yield, strong adaptability and nutrient richness. Sweet potato has played a significant role in ensuring food security and family income opportunities for local populations in China for years of experience. The storage roots, which provide abundant nutrition and health benefits to people, are the mainly harvested and consumed parts of sweet potato. However, after harvest, physiological disorders, such as sprouting, mechanical injury and infectious postharvest diseases, increase the magnitude of sweet potato root quality decline and nutritional compound losses. Ethylene and 1-methylcyclopropene (1-MCP) were considered to be effective commercial treatments in sweet potato postharvest. Exogenous ethylene and 1-MCP treatment could successfully inhibit root sprouts and reduce rot decay without affecting the storage quality of sweet potato. This review aims to summarize the latest available information on the effects of ethylene and 1-MCP with respect to enhancing or impairing sweet potato root quality. A better understanding of the influence of ethylene and 1-MCP on root quality parameters will be useful to further explore the role and mechanisms of action of ethylene in regulating the postharvest storage of sweet potato roots and contributions to technological development and innovation.

“…There was wide variation in the breeding lines in post-curing harvest yield; however, the best lines were HM 26, HM 3, and HM 34. This metric accounts for the yield lost during the curing process and are vital for fresh market export and storage This metric is related to factors other than just the curing process, including insect damage and shape [28]. Severe root damage from the sweet potato weevil (Cylas formicarius), a common sweet potato pest in Hawaii, prevented post-curing measurements from being taken during the Waimānalo-2018 trial.…”

Evaluation of Hawaiian Heritage Sweet Potato (Ipomoea batatas (L.) Lam.) Breeding Lines

Producing ‘Hawaiian Heritage’ cultivars can raise the market value of locally grown sweet potatoes and increase small farmer earnings in Hawaii. Twelve sweet potato breeding lines (Ipomea batatas L.), derived from the Hawaiian maternal parent ‘Mohihi’, together with four check varieties, were trialed under organic management conditions across three environments (site-year combinations) in Oahu, Hawaii (Waimānalo-2018, Waimānalo-2019 and Poamoho-2019). Trials were harvested five months after planting, consistent with local commercial production standards. There were significant differences in fresh harvest yield, post-curing yield, shape, and quality between environments and cultivars. The ‘Hawaiian Heritage’ lines HM 26 and HM 34 outperformed the commercial standard, demonstrating the potential use of traditional Hawaiian germplasm in modern breeding programs. Additionally, ‘Hawaiian Heritage’ lines (e.g., HM 32 and HM 17) with unique traits favored by the local community may be suitable breeding materials for niche markets.

“…If the damaged skin of sweet potato could not become dry immediately, the root becomes susceptible to fungus and bacteria thus sharply increasing the decay rate; and the enhanced respiration rate by the mechanical injury would further cause greater loss. Therefore, it is essential to heal the wound before storage for many roots and tubers to reduce their decay during storage [5,6] . Phloroglucinol staining is a popular method for detecting the curing extent of sweet potato, since lignin in plant cell wall can be stained by phloroglucinol in the presence of alcohol and hydrochloric acid (HCl).…”

Wound healing treatment after harvest is a critical step to protect sweet potatoes from pathogens. The method of phloroglucinol staining is commonly used for detecting callus. However, this method is not easy to identify the degree of callus as the color change is not obvious compared with non-curing roots for some cultivars. A new method based on the principle of starch test by iodine was developed for the detection of wound healing. After healing, the reducing sugar content increased while the starch content decreased to a lower level compared to that of the non-curing roots. Moreover, the antioxidant capacity of the sweet potato after wound healing was higher than that in the control. Wound healing combined with ethylene, 1-methylcyclopropene (1-MCP), chlorpropham or abscisic acid were studied for inhibiting sprout of sweet potato root caused by high temperature during curing. The results showed ethylene and 1-MCP treatment had no negative effect on wound healing. Moreover, 1-MCP treatment was the most effective one on the suppression of sprouting and decay of sweet potato. The results indicate that iodine solution staining is a useful and rapid method to identify the wound healing extent, and 1-MCP treatment can effectively inhibit root sprouting during wound healing and the subsequent long-term storage.
