The ecological significance of seed impermeability in the annual legume pastures of southern Australia
The frequent failure of improved pastures to persist is partly due to the species or cultivar seed dormancy mechanism being unsuited to the environment. Evidence indicates that seed coat impermeability is the most important of the dormancy mechanisms controlling the germination of many annual legumes. Failures occur when the degree of impermeability in the species or cultivar is either insufficient, or excessive for the environment.
