Abstract

The present study was conducted to establish the suppression condition of lateral root development for producing high-quality peanut sprouts. The result of Chamsiru or 6BA treatment on peanut sprouts 'Jopyeong' and 'Vietnam' showed that the higher concentration of the solutions showed the better effect for suppressing lateral root development, regardless of the kinds of lateral root inhibitor. Compared to Chamsiru, 6BA showed better effect for suppressing lateral root development, and the effect was more obvious for 'Jopyeong' than 'Vietnam'. The alternant irrigation of Chamsiru and 6BA solution could produce high-quality peanut sprouts by inhibiting bacteria activity in solution and promoting of hypocotyl and root growth, while suppressing the lateral root development. The treatment of mixture solution of $GA_3$ and Chamsiru improved the overall growth of peanut sprouts, and the effect was the highest in the treatment of '$GA_3\;50mg{\cdot}L^{-1}$ + Chamsiru $8.40mg{\cdot}L^{-1}$'.

본 연구는 고품질 땅콩나물 생산을 위해서 세근발생을 억제시키는 생장조절제의 처리 효과를 검정하기 위해 수행되었다. 땅콩나물의 세근발생억제제인 참시루와 6BA를 '조평'과 '베트남'땅콩에 처리하면 세근발생억제제의 처리농도가 높을수록 세근 발생수는 감소하였다. 그 효과는 6BA가 참시루보다 우수하였고, '베트남' 땅콩보다는 '조평'에서 세근발생억제 효과가 명확하였다. 참시루 및 6BA의 배양용액을 1일간 간격으로 교체하면 배양용액을 교체하지 않는 처리구에 비해 부패균 활동을 억제시켜 하배축 생장을 촉진시킨 반면 세근발생은 억제시켜 고품질 땅콩나물 생산이 가능하였다. 땅콩나물 재배의 배양용액에 $GA_3$와 참시루를 혼용하여 처리하면 땅콩나물의 생육을 향상시켰고, 적정 처리조건은 $GA_3\;50mg{\cdot}L^{-1}$ + Chamsiru $8.40mg{\cdot}L^{-1}$ 처리였다.
