Polytrichum formosum. Recovery of the chlorophyll-fluorescence parameter Fv/Fm after desiccation at 43 % RH in the presence of protein-synthesis inhibitors. Arrows show time of re-wetting. (A) Recovery in dark after 9 d of desiccation; circles, control; triangles, 3·0 mmol l–1 chloramphenicol (CMP); diamonds, 0·3 mmol l–1 cycloheximide (CHX). Points are means of three replicates: error bars are omitted for clarity, the sample standard deviation from a pooled estimate is 0·035 (treatment differences not significant). (B) Recovery in light (approx. 150 µmol m–2 s–1 PPFD), showing rapid decline in CMP-treated samples, and slower decline in CHX. Means of five replicates, with standard deviation.
