Parameters extrapolated from the O-J-I-P transients during Klebsormidium sp. (SCHW) dehydration (±standard deviation) under low light (25 μmol photons m⁻² s⁻¹) and saturating light for photosynthesis (185 μmol photons m⁻² s⁻¹)

OJIP parameters during dehydration		Low light	Saturating light
F o	Minimal fluorescence in dark	0.22 (0.06)	0.44 (0.06)*
F m	Maximal fluorescence in dark	0.63 (0.14)	0.76 (0.07)
F v/F m	Maximum quantum yield	0.66 (0.06)	0.43 (0.03)*
V j	Fluorescence at the J-step	0.48 (0.17)	0.83 (0.07)*

The parameter V _j was calculated according to the equation of Strasser et al. (2000). Asterisks indicate statistically significant differences from the low light treatment
