Reaction of photosynthetic apparatus to dark desiccation sensitively detected by the induction of chlorophyll fluorescence quenching

Original language description

Chlorophyll fluorescence parameters F0, FM, FV/FM, FV/F0, the emission and excitation spectra and induction of fluorescence quenching coefficients qP and qN were followed during the desiccation of leaf segments of spring barley (Hordeum vulgare L. cv. Akcent) and detached leaves of an endohydric moss (Rhizomnium punctatum Hedw.) exposed to the same dark-desiccation conditions (35 % air relative humidity, 24 °C). A sensitive fluorescence parameter in the initial phases of tissue desiccation was looked for. A decrease of relative water content (RWC) was much faster in the moss leaves (to 30 % RWC in 10 min) than in barley leaves (to about 30 % RWC in 17 h). A rather insensitive parameter FV/FM started to decrease at 60 % RWC for the moss and at 30 % RWCfor the barley. A more pronounced decrease in comparison with FV/FM was observed in the case of the FV/F0. The ratio of bands (F685/F735) in the emission spectra at two excitation wavelengths (436 and 475 nm) was significantly changing on
