Fig. 4. The content of Chl-GG (A), Chl a (B) and Pchl-GG (C) in the primary leaves of 11-day-old etiolated Cucurbita pepo 'Miranda' seedlings during illumination. In the case of ALA-treated plants, the 11-day-old seedlings were incubated for additional 3 days in 10 mM ALA solution in the dark before illumination. The data are means ± SE, n = 3–4. FW = fresh weight. The pigments were extracted and analyzed using HPLC as described in the Experimental section.
