Abstract

All the seeds of rape (Brassica napus) sprout vegetables were germinated within three days after seeding irrelevant to the light colors. The total fresh weight of rape sprout vegetables at 6 days after seeding have been increased when grown under green and white color lights by 0.339g/10plants and 0.339g/10plants compared with the control. The total flavonoid contents in rape sprouts were increased under red and blue lights by 72.5 and 70.9mg${\cdot}L^{-1}$. Those DPPH radical scavenging activities at 2,000mg${\cdot}L^{-1}$ were increased by 90.0 and 90.3% which were sprouted and grown under blue and white lights. Nitrite radical scavenging activity of sprouts were most decreased compared with the control when grown under the red light by 57.4mg${\cdot}L^{-1}$. And mushroom tyrosinase inhibition activity of rape sprouts was extremely increased under the green light by 22.5mg${\cdot}L^{-1}$.

유채의 새싹 발아와 생리활성에 효과적인 영향을 미치는 LED 광질 종류를 구명하기 위해 청색, 녹색, 적색, 백색, 황색, 적색+청색광을 발광 14시간, 암조건 10시간, 주간 $25^{\circ}C$, 야간 $18^{\circ}C$로 조절하여 종자 발아와 새싹을 생장을 시켰다. 생리활성 조사는 새싹을 메탄올로 추출한 것을 이용하여 실시하였다. 종자 발아율과 발아속도는 광질에 관계없이 3일 만에 100% 발아 되었다. 파종 후 6일째의 신선중은 녹색광과 백색광에서 각각 0.339g/10plants 및 0.339g/10plants로 높았다. 새싹의 총플라보노이드 함량은 적색광과 백색광 처리구에서 각각 72.5 및 70.9mg${\cdot}L^{-1}$로 많았다. 전자공여능은 추출물 2,000mg${\cdot}L^{-1}$일때 청색광과 백색광 처리구에서 각각 90.0 및 90.3%로 높았다. 아질산염 소거능은 적색광 처리구에서 57.4mg${\cdot}L^{-1}$로 가장 낮게 나타났다. Tyrosinase 저해 활성은 녹색광 처리구에서 22.5mg${\cdot}L^{-1}$로 가장 많이 나타났다.
