Summary: This study investigated the relationship between antioxidant capacity in sweet potato leaves and storage properties, finding a positive correlation between antioxidant enzyme activity and storage tolerance, and a negative correlation between alpha-amylase activity and storage tolerance. This provides a convenient means for screening storage-tolerant sweet potato cultivars.

Summary: This study aimed to uncover the accumulation and phytotoxicity mechanism of sweet potato roots after exposure to toxic levels of uranium and cadmium. Different sweet potato cultivars showed varietal differences in U and Cd accumulation, with high concentrations inhibiting growth and damaging root microstructure. U and Cd mainly accumulated in root cell walls and vacuoles, affecting mineral nutrition and photosynthetic metabolism, while RNA-seq analysis revealed responses in cell wall and plant hormone signal transduction pathways to U and Cd toxicity.

Summary: This study evaluated the effects of growing season on the structural, morphological, and physicochemical properties of sweet potato starches. The results showed that starches isolated from plants grown in the rainy season had a more ordered structure, higher gelatinization temperatures, thermal stability, and resistant starch content. Starches from plants grown in the dry season had a higher percentage of small granules, lower crystallinity, and lower gelatinization temperatures. These findings can help the supply chain plan and target suitable markets for naturally modified sweet potato starches.

Summary: China is the world's largest producer of sweet potato, with the majority of the global supply coming from China. Two main cultivation systems, raised beds and raised beds mulched with plastic film, are widely used in northern China. This study developed a 2CGFS-2 compound sweet potato transplanter and investigated its performance under different sweet potato varieties and cultivation systems. The results showed that the transplanter had a low missing seedling rate and high qualified rate of transplanting population, as well as precise placement of sweet potato slips, which is important for sweet potato cultivation systems.

Summary: This study demonstrates that using spectral vegetation indices can effectively monitor the growth dynamics of sweet potato and differentiate different growth stages, predicting crop yield. Additionally, the growth stage was found to be the optimal time for yield estimation in two growing seasons.

Summary: The study showed that flesh color plays a key role in consumers' sensory and hedonic expectations, with Uruguayan consumers favoring traditional purple-skin sweet potatoes with orange flesh for positive sensory expectations. However, after tasting, flesh color does not seem to have a significant influence on consumer liking.

Summary: This study investigated the inoculation effects of a diazotrophic endophyte (Bradyrhizobium sp. AT1) on three different cultivars of sweet potato under different conditions. The results showed that AT1 inoculation increased root length in "Beniazuma" and "Ayamurasaki" but suppressed it in "Kokei No. 14" in pots. AT1 inoculation also enhanced shoot growth in "Beniazuma" and tuber formation in "Ayamurasaki" in containers. Field experiments demonstrated that AT1 inoculation promoted the growth of "Beniazuma" and "Ayamurasaki". Additionally, AT1 inoculation of micropropagated "Beniazuma" led to Ndfa and ARA five months after inoculation.

Summary: Imaging spectroscopy is a reliable analytical method for characterizing and quantifying quality attributes of agricultural products, particularly in tubers. By providing spectral information relevant to food quality, it can rapidly and non-destructively classify, authenticate, and predict quality parameters. Machine learning algorithms coupled with feature variable identification approaches have yielded acceptable results in evaluating tuber quality.

Summary: Fresh-cut Anggun packed in nylon showed the best performance in terms of color retention, texture, and respiration rate when stored at 5 degrees Celsius, with a shelf life of up to 14 days. The uncompetitive Michaelis-Menten model was proven to be a good fit for modeling the respiration rate of fresh-cut Anggun.

Summary: This study investigated the effects of chelated zinc fertilizers on the growth of sweet potatoes. The results showed that chelated zinc fertilizers can increase zinc concentration in sweet potato roots and reduce leaf burn. Among the different types of chelated zinc fertilizers, glycine-chelated zinc performed the best.
