Abstract

Lateral roots of soybean sprout might reduce the quality. The study was done to measure the effect of light quality treated during 24 hour imbibition or 6 day culture on growth and development of soybean sprouts on the 6th day after culture. With the soybean seeds imbibed in 4 ppm benzyladenopurine (BA) solution for last 6 hours of the imbibition, blue and red lights were treated during the imbibition, but during 6 day culture, blue and red or far-red light treatments were done for 50 minutes or 5 hours a day, respectively, the periods taking for their cotyledons to turn green color, On the 6th day after culture, the soybean sprouts were classified by 4 categories on the base of hypocotyl length;>7cm, 4 to 7cm, <4cm and non-germination, and their lateral roots, hypocotyl diameters and fraction dry weights were measured. Blue and red lights treated during the imbibition completely blocked lateral root formation regardless of the lights treated during the culture, and showed nearly the same rate of hypocotyls of longer than 4cm. The period of each light treatment forced during the culture did not influence the growth of soybean sprouts. far-red light treated for 5 hours everyday, however, had the least rate of seed germination and hypocotyls of longer than 7cm of the light quality treatments. In addition, red and far-red lights almost equally having the commercial soybean sprouts of longer than 4cm hypocotyls move elongated and selenderized than blue light and dark treatment, meaning the growth and morphology of soybean sprouts was affected by light treatments during the culture.

콩나물의 내수규모는 아주 크면서도 실용적인 기술개발은 미진한 실정이다. 본 시험에서는 24시간의 침종 및 6일간의 재배중 가하여지는 광질처리가 콩나물의 발아, 세근발생 및 생장에 미치는 영향을 구명하고자 침종기간에는 청색광과 적색광을, 재배기간에는 청색광, 적색광, 초적색광 및 암 처리를 가하면서 콩나물을 재배한 결과를 요약하면 다음과 같다. 1. 침종시 가하여지는 적색광과 청색광 처리는 재배중 가하여지는 광질처리에 관계없이 세근이 전혀 발생되지 않았다. 2. 침종시 가하여지는 적색광과 청색광 처리는 하배축 길이가 상품으로 출하 가능한 4cm이상의 비율이 비슷한 것으로 조사되었다. 3. 콩나물 자엽의 녹화는 적색광과 청색광은 50분, 초적색광은 300분이 소요되었으나 재배기간중 매일 이러한 범위 내에 처리할 경우 콩나물의 생장에는 영향이 없는 것으로 나타났다. 4. 재배기간중 가하여지는 여타 광질처리에 비하여 초적색광 처리에서 하배축 길이가 7cm이상인 개체의 비율은 가장 낮은 반면, 미발아 종자의 비율은 가장 높았다 5. 재배기간중 가하여지는 적색광과 초적색광 처리는 청색광과 암 처리보다 하배축을 신장을 억제시킴과 동시에 굵게하는 것으로 조사되었다.
