Abstract

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~$28.2^{\circ}C$, respectively. Accumulated temperature was 3,122~$3,282^{\circ}C$. 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.

재배지역에 따라서 동일한 고구마 품종이 나타내는 생육특성과 괴근특성을 구명하고 보다 우수한 품질의 고구마를 생산하기 위한 기초자료를 얻고자 수행된 결과는 다음과 같다. 1. 지역별 재배 토양의 토성은 논산시험구가 식양토, 함양이 양토였으며, 무안, 익산, 보령은 사질양토였다. 또한 보령시험구는 강우량이 많아 일조시간이 짧았으며 적산온도는 익산시험구가 높게 나타났다. 2. 전기전도도는 무안시험구가 다른 지역 시험구에 비해 높았고, 유기물 함량 및 유효인산, 양이온치환용량은 보령이 높아 토양 비옥도가 높게 나타났다. 3. 덩굴무게는 보령시험구에서 많았으며 수량과 당도는 무안과 익산에서 높았다. 4. 고구마의 형태는 익산시험구는 단방추형이었고, 함양은 장방추형으로 길쭉한 경향이었으며, 육색은 익산과 무안시험구의 색도가 낮아 어두운 색을 보였다. 5. 전분가 및 당도는 무안과 익산시험구가 높았고 함양은 낮은 경향이었다.
