Comparison of Fv/Fm between lines RIL045 (black circle), RIL083 (white circle), RIL232 (white triangle), RIL272 (black square), and RIL310 (white square) depending on Glc and nitrogen supply. Fv/Fm ratio was estimated on the whole rosettes of plants grown on agar medium containing 30 mm nitrogen without sugar (HN; A) or 30 mm nitrogen with 111 mm Glc (HNG; B), or 4.7 mm nitrogen without sugar (LN; C) or 4.7 mm nitrogen with 111 mm Glc (LNG; D). Data are the means of at least 10 plants ± sd. The same biological experiment was repeated four times and gave similar results.
