Abstract: | Germination of caryopses and seeds of Festuca rubra L. coll. from wet, dry and dune areas in the salt marsh at Skallingen, Jutland, Denmark, was tested in deionized water and diluted sea water. A strong correlation was found between percentage of germination and the topography of the collection sites. Further it was found that salt tolerance for the most salt tolerant populations, growing on low dunes, was provided partly by the husks rather than only being a characteristic of the seed. In less salt tolerant populations from low and dry areas, husks had no influence on germination percentage in 25% sea water. |
