Deetiolation of 6-day-old etiolated wheat leaves under continuous white light (100 μmol photons m^-2 s^-1).

A) Chlorophyll content; B) Carotenoid content; Statistically insignificant differences in A and B (p > 0.01) were marked with the same letters (n = 3); C) Representative 77 K fluorescence emission spectra for M leaf fragments; Excitation at 440 nm; D) Scatter of the position of fluorescence emission maximum (indicated with a green grid line in C) in the course of greening, as representative to the pooled sample taken for SOD native PAGE analysis; E) Average relative activity of SODs for M leaf fragments calculated with respect to the total SOD activity in a single lane of gel; 3–5 gels were compared for each greening time; the data represents the mean ± SD, n = 3–5.
