英文摘要	Spectral composition and nutrients status are important environmental factors for biomass production. For realizing the economical and efficient production of duckweed [Spirodela polyrhiza (L.) Schleiden] turion, a promising starch-rich biofuel feedstock, impacts of tailored-lights combined with eutrophic/oligotrophic medium was investigated in this study. Results revealed that nutrients starvation was better for turion production and optimized spectral composition could significantly enhance it. Accompanied with simultaneously enhanced frond biomass and starch content, starch yield of 32.34 g/m(2) under fluorescent lamp was largely elevated to 51.71 g/m(2) by red/blue: 1/2. Especially, lights with higher ratio of red spectrum exerted strong inductive effect on turion formation under eutrophic condition. Considering the energy consumption, red/blue: 4/1 was the optimal option as it cut down energy cost by 12.56% and owned the highest production efficiency. Moreover, appropriate nutrients supplementation can further improve the starch productivity. Finally, an efficient and economical culture method for turion and starch production was established.
