在红光加蓝光（红/蓝光PPFD比为4/1）下生长的水稻植株中，在白色光1，600和250 μ mol m（-2）s（-1）下测量的每单位叶面积的光合速率高于仅在红光下生长的植株。较高的光合速率与较高的总氮含量的叶片，这是伴随着大量的光合限制过程的关键组件，包括Rubisco，细胞色素f，叶绿素和LHCII。这些结果表明，增加叶片全氮含量的补充蓝光诱导增强光饱和和光限制光合作用。
In rice plants grown under red light supplemented with blue light (red/blue-light PPFD ratio was 4/1), photosynthetic rates per unit leaf area measured under white light at 1,600 and 250 mumol m(-2) s(-1) were higher than those in the plants grown under red light alone. The higher photosynthetic rates were associated with higher total N content of leaves, which was accompanied by larger amounts of key components of photosynthesis-limiting processes, including Rubisco, Cyt f, Chl and LHCII. These results suggested that the increase in total N content of leaves induced by supplemental blue light enhanced both light-saturated and light-limited photosynthesis.
