Název v původním jazyce

Effect of water content components on desiccation and recovery in Sphagnum mosses

Popis výsledku v původním jazyce

When desiccated, the hummock forming species S. fuscum and S. magellanicum lost more water before turgor started dropping than other sphagna inhabiting wet, less exposed habitats. While the osmotic potentials at full turgor were similar in all species ,hummock sphagna had clearly more rigid cell walls resulting in loss of turgor and photosynthetic activity at higher relative water contents. Nevertheless, hummock sphagna recovered more completely after rehydration than species of wet habitats. A. androgynum, species of desiccated habitats, responded to desiccation similarly to hummock sphagna suggesting that their desiccation tolerance may have a similar physiological basis. Hummock sphagna have, on the one hand, better avoidance mechanisms against desiccation and, on the other hand, also higher inherent physiological tolerance. This may help them to persist in drought exposed hummocks.
