Variations of photosynthetic pigments content.

<p>(A) Chlorophyll <i>a</i> (Chl <i>a</i>; pg cell^–1), (B) Fucoxanthin (Fuco; pg cell^–1), (C) β-carotene : Chl <i>a</i> ratio, (D) Chlorophyll <i>c</i>₂ : Chl <i>a</i> ratio and (E) Chlorophyll <i>c</i>₃ : Chl <i>a</i> ratio. B-L, BR-L, BRG-L, R-L are blue, blue-red, blue-red-green, and red low light conditions, respectively; B-H, BR-H, and BRG-H are blue, blue-red, blue-red-green high light conditions, respectively. Data represent mean ± SD (<i>n</i> = 21).
