Abstract

We examined the effects of light colors (wavelength) and light quantities on the yield ratio and quality of cultivated cowpea sprouts. All light colors resulted in a lower cowpea sprout yield ratio compared to the untreated condition (darkness), but were similar in hard seed ratio. All light colors promoted the growth of the epicotyl and root when compared to the untreated condition, but limited the growth of the hypocotyl. White light (458 nm) significantly improved grade by increasing the lightness of the cotyledon and the hypocotyl and the yellowness of the hypocotyl. The Fe content of cowpea sprouts was higher in those grown under red light (632 nm), and the total amino acid content was higher for those grown under yellow light (560 nm), white light (458 nm), and blue light (460 nm) compared to plants grown in the untreated condition (darkness). The yield ratio of cowpea sprouts was lower in the yellow light condition (560 nm) at lower light quantity, but no differences were observed at other light colors and quantities. The lightness and yellowness of cowpea sprouts was higher in the yellow light (560 nm) and red light (632 nm) at lower light quantity, redness was lower. No significant differences were observed in the content of normal and inorganic components according to the light quantities of each light color, except that Fe content was higher in sprouts grown under red light (632 nm) as light quantity increased. Total amino acid content was slightly higher in sprouts grown under white light (458 nm) and blue light (460 nm) as light quantity increased.

본 연구는 동부나물을 재배할 때 광질과 광량에 따른 생산수율과 품질 등에 미치는 영향을 구명하고자 수행하였다. 1. 처리한 모든 광질에서 무처리(암)에 비해 동부나물의 생산수율이 낮았으나 경실비율은 비슷하였고, 상배축과 뿌리 생장을 촉진시키는 반면 하배축 생장을 억제하는 경향이었다. 2. 백색광(458 nm) 처리가 동부나물의 상배축과 하배축의 명도 및 하배축의 황색도를 증가시켰다. 3. 동부나물의 Fe 함량은 적색광(632 nm)에서 많았고, 총아미노산 함량은 황색광(560 nm), 백색광 및 청색광(460 nm)이 무처리(암)보다 많은 경향이었다. 4. 황색광에서 광량이 낮을 때 동부나물의 생산수율이 낮았고, 기타 광질은 광량에 따른 차이가 없었다. 5. 황색광과 적색광은 광량이 낮을 때 명도와 황색도가 높았고 적색도가 낮았다. 6. 처리 광질의 광량에 따른 일반성분과 무기성분 함량은 차이가 없으나, 적색광에서는 광량이 높을 때 Fe 함량이 많았다. 총아미노산 함량은 백색광과 청색광에서 광량이 높을 때 미미하게 많았다.
