  • The response of the drought-tolerant moss Tortula ruralis ([Hedw.] Gaertn., Meyer, Scherb.) to freezing and thawing at controlled rates has been studied. Slow freezing (at 3 C per hour to -30 C) of hydrated T. ruralis leads to only temporary, reversible changes in metabolism. These changes can be considered to result from desiccation due to extracellular ice formation. In contrast, rapid freezing in liquid N(2) and thawing in 20 C water leads to deterioration in all aspects of metabolism… CONTINUE READING
