Abstract

We analyzed the growth and quality characteristics of barley sprouts grown under artificial light sources consisting of a fluorescent lamp or light-emitting diode (LED) in an aquaculture system (grown with water only, without nutrients). At the end of the observation period, the shoots grown under the fluorescent lamp treatment were the longest, followed by the LED treatment and natural light-treatment. It was also observed that growth was faster for sprouts subjected to a non-sterilizing treatment than those subjected to a 70% ethanol treatment. As the seed sowing rate for planting trays increased, the yield of harvested barley sprouts increased; among light treatments, the natural light treatment resulted in the lowest yield, while the fluorescent light treatment resulted in the highest. The total phenol and total flavonoid contents of extracts of the barley sprouts were highest for the natural light treatment, but TEAC and FRAP were both highest for the fluorescent lamp treatment. The essential amino acid content ranged from 41.64 to 45.93 mg/g and was relatively higher for the natural light treatment than the other two treatments, while the content of non-essential amino acids was highest for the LED treatment. The total amino acid content was highest for the LED treatment at 97.47 ± 6.30 mg/g, for which the content of non-essential amino acids (53.17%) was higher than that of essential amino acids (46.83%).

본 연구는 물만을 공급하는 수경방식에서 인공광원에 따른 새싹보리의 생장과 품질에 미치는 영향을 분석하였다. 생육기간이 지나면서 초장이 길어지는 것을 관찰할 수 있었으며 지상부의 경우 형광등 처리구가 가장 높았으며 다음으로 LED 처리구, 자연광 처리구 순이었다. 또 에탄올 소독 처리구보다 무소독 처리구의 생장이 더 빠른 것을 관찰할 수 있었다. 종자 파종량이 많을수록 수확된 새싹보리의 수확량은 증가하였는데, 자연광 처리구가 가장 적었으며 형광등 처리구가 가장 높았다. 새싹보리 추출물의 총페놀 및 총플라보노이드 함량은 자연광 처리구가 가장 높았으나 TEAC와 FRAP은 모두 형광등 처리구에서 가장 높게 나타났다. 필수아미노산 함량은 41.64 ~ 45.93 mg/g의 범위로 자연광 처리구가 다른 두처리구에 비해 상대적으로 높은 함량을 나타내었으며, 비필수아미노산 함량은 45.51 ~ 53.69 mg/g의 범위로 LED 처리구에서 가장 높았다. 총아미노산 함량은 LED 처리구에서 97.47 ± 6.30 mg/g으로 가장 높았으며, 필수아미노산(46.83%)보다 비필수아미노산(53.17%)이 더 많이 분포하였다.
