Abstract

This study was carried out to identify the treatment methods for the inhibition of lateral roots and promotion of hypocotyl enlargement using plant growth regulators for the production of high quality soybean sprouts. Inhibition of lateral root formation was not significant from the $CA_3$ and NAA treatments. From the treatment of BAP, lateral roots were not occurred at all, and hypocotyl enlargement was promoted at the low concentration of $10\;mg{\cdot}L^{-1}\;and\;15\;mg{\cdot}L^{-1}$. Promotion of hypocotyl enlargement was higher as the BAP treatment time was shorter. The optimum time of BAP treatment was 6 hours. Occurrence ratio of lateral roots were low and hypocotyl enlargement was promoted from water supply every 24 hours after BAP treatment. In the indole B treatment, lateral roots occurrence was very low with the concentration of 1.1%, which is much lower than the optimum concentration of 4.2%.

본 실험은 고품질의 콩나물 생산을 위한 기초연구로서 식물생장조절제를 이용한 세근발생 억제 및 하배축비대촉진을 위한 처리 방법을 구명하고자 실험을 수행하여 다음과 같은 결과를 얻었다. 식물생장조절제 중 $GA_3$나 NAA 처리는 세근발생 억제효과가 미약하였다. 반면 BAP처이믐 세근발생이 전혀 일어나지 않았고 하배축의 비대를 촉진하였는데, 저농도인 $10mg{\cdot}L^{-1}$ 및 $15mg{\cdot}L^{-1}$ 처리에서도 그 효과가 인정되었다. BAP의 처리시간은 짧을수록 하배축 비대가 촉진되었고 하배축 비대를 촉진하는 처리시간은 6시간 처리였다. BAP 처리 후 24시간 간격으로 관수는 세근 발생율이 낮았고 하배축 비대는 촉진되었다. 인돌비는 적정농도로 알려져 있는 4.2%보다 낮은 농도인 1.1%용액을 처리하더라도 세근 발생이 크게 문제되지 않았다.
