The analysis of PS II photochemical activity using single and multi-turnover excitations

Popis výsledku v původním jazyce

Paper describes chlorophyll a fluorescence measurements in algal cells, and intact plant leaves and isolated chloroplasts. It focuses on amplitude and 10 mu-resolved kinetics of variable fluorescence responses upon excitation with fluorescence-saturatingpulses (SP) and with 25 mu s saturating single turnover flashes (STF) which are exposed before, during and after a 100 s actinic illumination (AL) of low and high intensity. In addition to the amply documented suppression of the maximal variable fluorescence from F-m to F'(m), the relative proportion of the distinguished O-J-, J-I- and I-P-phases of an SP-induced response is shown to be distinctly different in dark- and light-adapted leaves. The O-J-phase in the 0.01-1 ms time range is much less sensitive to light adaptation than the other phases in the 1-200 ms range. In algae and chloroplasts, the amplitude F-m(ST) of the STF-induced response is hardly affected by a shift from the dark- to the light-activated steady state. The result
