Determination of optimum red and blue lighting conditions for production of red-leaf lettuce cultured under LEDs Open
播種からおよそ1か月の栽培期間において，赤単色光が青単色光や赤青混合光に比べて，リーフレタス（レッドファイヤー）の可食部重量を確保するのに効率の良い光であることがわかった．赤単色光に比べて青単色光では成育が小さいのは，葉面入射光強度あたりの光合成効率が低いことと葉の展開が抑制されることに起因するものと推定された．青色光は50μmol m-2 s-1以上の光強度において葉縁を紫に着色させた．しかし50μmol m-2 s-1以上の光強度で青色光が照射されると播種からおよそ１か…
