Abstract

This study was conducted to find out optimum cultivars, and growth temperature and stage in peanut sprout for resveratrol production. Morphological characteristic, days to 50% of the final germination percentage(T₅₀) and early growth vigor were measured in 8 different peanut varieties. In result ‘Jopyeong’ appeared to be the most appropriate cultivar for peanut production because of its lower contamination rate, lesser lateral root formation, and thicker hypocotyl length. Optimum temperature for growing peanut sprouts was determined 27. Content of resveratrol was examined by high performance liquid chromatography(HPLC) to investigate appropriate growth stage of peanut sprouts for resveratrol production. Resveratrol was higher than 17.0μg/g in peanuts sprouts 9 days after plating. Considering peanut sprout’s shapes and content of resveratrol into account, it was most appropriate to harvest in 9-day after germination.

땅콩나물의 재배에 적합한 온도와 품종, 그리고 최적 레스베라트롤 생산을 위한 생육단계를 구명하고자 본 연 구를 수행하였다. 땅콩나물용 적정품종을 선발하고자 8 가지 국내외 육성품종의 외형적 특징, 발아율, 발아세, 유묘활력을 조사하였다. 그 결과 소비자의 요구를 반영 하여 세근 발생량이 낮고 하배축이 굵은 ‘조평’이 가장 적절하였고, 땅콩나물 재배에 적합한 온도는 27°C로 판 단되었다. 레스베라트롤 함량이 높은 땅콩나물의 적정 생육시기를 구명하고자 치상 후 생육조사와 동시에 HPLC를 이용한 레스베라트롤 함량을 조사한 결과 레스 베라트롤은 치상 후 9일차에 17.0μg/g 이상의 높은 함유 량을 나타내었다. 따라서 땅콩나물은 생산적 측면과 레 스베라트롤의 함량을 고려했을 때 치상 후 9일차에 땅 콩나물을 수확하는 것이 가장 적합할 것으로 판단된다.
