Effects of salinity on growth of plant species from terrestrializing fens

摘要: Abstract Terrestrializing lowland fens may be temporarily exposed to elevated surface water salinity, which have serious consequences for nature conservation. We investigated the response of five fresh fen plant species salinity. In a controlled greenhouse experiment, these were salt concentrations up 3000 mg Cl − l −1 . Total biomass together was significantly reduced salinity levels from 200 mg Four individual showed leaf death and relative growth rate reduction, with effects at 1000 mg Succisa pratensis , Thelypteris palustris Viola Myosotis scorpioides Comarum palustre no significant (.05 level) sensitivity. Biomass distribution as well. Root-shoot ratio four affected by in least two cases seemed related death. Differences specific area result only observed C. Dry matter content increased Salinity tolerance did not correspond environmental distributions species, nor could traits tolerance. Surface affect vegetation development terrestrializing low concentrations. A reduction would cause fitness some lead root mat growth. Exposure higher eventually decrease richness.
