Fig. 5. — Changes in modulated chlorophyll fluorescence in hydrated Rhytidium rugosum during slow desiccation. (A) Desiccated moss thalli were hydrated in 0.2% aqueous glutaraldehyde shortly before the measuring beam was turned on. (B) Rehydrated thalli were exposed for 1 h to 0.2% glutaraldehyde before the measuring beam was turned on. (C) Control experiment without glutaraldehyde, otherwise as in B. Saturating light pulses were given every 500 s to probe for stable charge separation in PSII RCs. Measuring beam (m. b.) was turned on and off as shown by up and down arrows, respectively.
