두채(豆彩)의 기호도(嗜好度)와 생산수율(生産收率)을 향상(向上)시킬 수 있는 재배(栽培)기술(技術)의 확립(確立)을 위한 기초연구(基礎硏究)로 각(各) 품종별(品種別) 원두(原豆)를 침적(沈積) 및 재배시(栽培時) 생육특성(生育特性)을 조사(調査)하였다. 원두(原豆)를 $18^{circ}C$에서 4시간(時間) 침전후(沈澱後) 수분흡수율(水分吸收率)은 $167.0{sim}194.5%$ 범위(範圍)였는데 발원율(發源率)과는 큰 관계(關係)가 없었다. 7일(日) 재배(栽培) 후(後) 구예태(求禮太)가 생산수율(生産收率)이 가장 높고 생장조절제(生長調節劑) 처리시(處理時) giberellin 1 ppm 처리구(處理區)가 가장 높은 수율(收率)을 얻었다. 또한 대량생산시(大量生産時)에는 $25^{circ}C$ 이상의 물로 수주(水柱)할 때 발생(發生)되는 두채(豆彩)의 변질(變質)을 막기 위해 지하수(地下水)로 직접수주(直接水柱)하는 것이 바람직하다.
As a primary study for the improvement of yield and preference of soybean sprouts, the water absorption rates by soaking and the growing characteristics of sprouts were investigated. When the soybeans were soaked in subterranean water at $18^{circ}C$ for 4 hours, water absorption rates by weight percent of soybeans were ranged $167.0{sim}194.5%$, and it means that the absorption rates do not greatly influence its germination rates. The yield of soybean sprout whose common name is Guryetai and of the sprout treated with 1 ppm Gibberellin marked the highest value, 837% and 585%, respectively. In case of industrial cultivation of soybean sprout, it is supposed that sprinkling with subterranean water is good for prevention of deterioration by growth of microorganisms and respiratory heat.
