Table II. Chl a fluorescence parameters of wild-type (Col-0), atcgl160-1, and oeAtCGL160-eGFP plants.
Leaves were exposed to 100 µmol photons m−2 s−1 for 15 min. The dark relaxation phase lasted 10 min. Averages values (n = 5–6) ± sd are provided. Fv/Fm, Maximal quantum yield of PSII; ΦII, effective quantum yield of PSII at 100 µmol photons m−2 s−1; 1-qP, excitation pressure.
