Abstract

Soybean sprout decay during its culture should be one of serious problems. The study was carried out to clarify the effect of water imbibition and acetic acid treatments on growth and morphological characters of the soybean sprouts. The soybean seeds of 3 cultivars (cv. Eunhakong, Pungsannamulkong and Junjery) imbibed in pure water or 0.l% acetic acid for 3 minutes before soaked for 6 hours into 1 ppm BA solution and aerated for 3 hours immediately before 6 day culture. On the 6th day, the sprouts were classified into 4 categories on the base of hypocotyl length; > 7cm, 4 to 7cm, > 4cm and not germinated and seed floating rate, their morphological characters, fresh fraction weights and productivity were measured. The best water imbibition for seed cleaning was to soak the seeds for 5 minutes and then to aerate soak them for 40 minutes. In Pungsannamulkong and Junjery, percentage of the sprouts with hypocotyls of longer than 4 cm was higher in water imbibition than in acetic acid treatment for seed disinfection although in Eunhakong there was no significant difference between the two treatments. Eunhakong and Junjery had greater lateral root formation rate and its number per sprout in water imbibition than in acetic acid treatment but Pungsannamulkong showed reverse result. Eunhakong and Pungsannamulkong, furthermore, had more total fresh weight in acetic acid treatment than in water imbibition but Junjery showed reverse result, although there was no significant difference between the two treatments in productivity of mass production system.

콩나물의 생산과정에서 야기되고 있는 부패를 방지하기 위한 다양한 방법이 제시되고 있다. 본 연구는 물에 침종하는 수침(水浸)을 이용한 종자정선과 0.1% acetic acid에 2분간 실시한 종자소독이 콩나물의 발아와 생장, 형태 및 생산수율에 미치는 영향을 조사하고자 실시하였던 바 그 결과를 요약하면 다음과 같다. 1. 물에 뜨는 부유 종자의 비율은 5분간 물에 침종시킨 종자를 건져 40분간 aeration 시켜 다시 물에 침종시킬 경우 가장 높았다. 2. 상품으로 판매가 가능한 하배축 길이가 4cm이상의 비율은 은하콩에서는 水浸(水浸)과 acetic acid 처리간 차이가 없었던 반면, 풍산 나물콩과 준저리에서는 acetic acid 처리에 비하여 가결 수침 처리(水浸 處理)에서 높았다. 3. 세근형성 비율과 개체당 세근수는 은하콩과 준저리에서는 수침 처리(水浸 處理)에서, 풍산나물콩은 acetic acid 처리에서 상대적으로 높고 많았다. 4. 개체당 전체생계중은 은하콩과 풍산나물콩에서는 수침 처리(水浸 處理) 보다는 acetic acid 처리에서 많았던 반면. 준저리는 이와 반대의 결과를 보였다. 그러나 준저리를 이용한 대량생산 체계에서의 생산 수율은 수침(水浸)을 이용한 종자정선과 acetic acid를 이용한 종자소독간에 차이가 없었다.
