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${\cdot}L^{-1}$.
