Abstract

The results of greenhouse experiments are reported aiming at an ecophysiological analysis of factors that determine the occurrence of Salicornia dolichostachya below the Mean High Water line and that of Salicornia brachystachya above this level. S. dolichostachya appeared to be better adapted to saline flooding conditions than S. brachystachya. The latter species however, tended to be more salt resistant than S. dolichostachya, a characteristic with adaptive value to the hypersaline conditions occurring in upper parts of salt marshes in dry summer periods. The two species do not seem to differ significantly in uptake by the root and translocation to the shoot of iron and manganese as found in greenhouse studies with sand and clay substrate and in nutrient solution experiments. These and other factors (a.o. morphology of the root system) are discussed to explain the vertical distribution of the two Salicornia species in salt marshes.
