“…The Pungwonmi tips showed significantly difference other cultivar, however, there was no difference between Hayanmi and Juhwwangmi ( p < .05). Choi et al ( 2011 ) studied the whitening activity of purple sweet potato extract, and the result showed 47.3% activity in Sinjami tubers, showing a trend similar to this study. The tyrosinase inhibitory activity of the tuber muscle was 32.82%–44.03%, and the tip was 57.59%–63.83%, indicating that the whitening effect of the tips was superior to that of the tubers.…”

Sweet potato (Ipomoea batatas L.) is an edible dicotyledon crop that belongs to the Convolvulaceae family. It is an excellent source of carbohydrates and a major food resource in Korea, along with rice and soybean. It is widely used as a functional food owing to its high content of not only carbohydrates but also phenolic compounds, carotenoids, vitamin C, anthocyanins, various minerals, and dietary fiber, and it is the 7th largest crop in the world (Bovell-Benjamin, 2007).Sweet potato has attracted a lot of attention because it is a crop that has simultaneously solved energy, food, and environmental problems of the 21st century owing to its strong environmental adaptability, and its roots, stems, and leaves can be consumed (Ishida et al., 2000). In addition, sweet potato is a food with high utility value because it is used for producing food, snacks, processed foods, vegetables, industrial products, and feed (O'Hair, 1984).The shape of sweet potato is largely divided into aboveground and underground parts. The aboveground part is composed of leaves, stems, flowers, and seeds, while the underground part is composed of roots. Sweet potato tips, which are 10 to 15 cm from the end of the stem, and leaves and stalks, which are among the shoots, are grown 50 to 60 days after tubers are directly cut into the field. Sweet potato tips can be harvested 8-10 times during the cultivation period, and the total yield is very high (130-180 t/ha) and has the advantage of easy harvesting (Lee, Park, et al., 2007). In recent years, the whole plant, tubers, tips, and stems of sweet potato

This research was performed to find out the root characteristics of sweetpotato (Ipomoea batatas LAM.) cultivars according to the cultivation regions. Total 10 sweetpotato culivars, 6 yellow, 2 purple and 2 orange, were used for experiment. Samples were cultivated in Muan, Iksan, Nonsan, Boryeong and Hamyang. Precipitation and average temperature during the growth period of sweetpotato cultivation were 882∼1,682 mm and 16.7∼28.2℃, respectively. Accumulated temperature was 3,122∼3,282℃. Soil texture was found of sandy loam in Muan, Iksan and Boryeong, sandy clay loam in Nonsan, and loam in Hamyang. The yield of root, dry matter content, starch value and soluble solids contents were high in Muan. The length/width ratio was high in Hamyang. The color values of sweetpotatoes were high in Nonsan. The protein content of sweetpotato powder was high in the Iksan, crude fat content and ash content were high in the Hamyang. The results of this study, we could see that root characteristics of sweetpotato in the same cultivars appeared differently depending on the cultivated regions.
