PROBLEM TO BE SOLVED: To provide a method for increasing a chlorogenic acid content of a Compositae plant.SOLUTION: The present invention provides a method for increasing a chlorogenic acid content of a Compositae plant. The method includes the step of irradiating a seedling of a Compositae plant with light of 400-500 nm in wavelength in a photosynthesis effective photonic flux density of 100-300 μmol m-2 s-1 for 16 hours or longer per day.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】キク科植物のクロロゲン酸含有量を増加させる方法を提供する。【解決手段】キク科植物の幼植物体に、波長400~500nmの光を光合成有効光量子束密度100~300μmol・m-2・s-1で1日あたり16時間以上照射する工程を備える、前記キク科植物のクロロゲン酸含有量を増加させる方法。【選択図】なし
