• Spectral components
• ICP-AES technology
• Lactuca sativa
• Mineral element

Mineral elements absorption and content of Lactuca sativa under different spectral component conditions were studied by ICP-AES technology. The results showed that: (1) For Lactuca sativa, the average proportion for Ca: Mg : K : Na : P was 5.5 : 2.5 2.3 : 1.5 : 1.0, the average proportion for Fe: Mn Zn : Cu : B was 25.9 : 5.9 : 2.8 : 1.1 : 1.0; (2)The absorptions for K, P, Ca, Mg and B are the largest under the LED treatment R/B=1 : 2.75, red light from fluorescent lamps and LED can both promote the absorptions of Fe and Cu; (3)The LED treatments exhibiting relatively higher content of mineral elements are R/B=1 : 2.75 and R/W=1 : 1 while higher dry matter accumulations are R/B=-1 : 2.75 and B/W=1 : 1.
