“…Tolerance of complete submergence by halophytes has rarely been studied. Notable exceptions are growth experiments using (artificial) tidal submergence which showed greater tolerance of submergence in a coastal, compared with an inland, species of Salicornia (Langlois & Ungar, 1976); and those assessing submergence tolerance, as influenced by NaCl concentrations, in S. perennis (Adams & Bate, 1994) and in S. maritima (Adams & Bate, 1995). Stem elongation when submerged was much slower in the marsh species S. perennis , which would naturally experience short periods of tidal submergence (Adams & Bate, 1994), as compared with some glycophytic wetland species that experience more prolonged floods (c.f.…”

SummaryFlooding is a common environmental variable with salinity. Submerged organs can suffer from O 2 deprivation and the resulting energy deficits can compromise ion transport processes essential for salinity tolerance. Tolerance of soil waterlogging in halophytes, as in glycophytes, is often associated with the production of adventitious roots containing aerenchyma, and the resultant internal O 2 supply. For some species, shallow rooting in aerobic upper soil layers appears to be the key to survival on frequently flooded soils, although little is known of the anoxia tolerance in halophytes. Halophytic species that inhabit waterlogged substrates are able to regulate their shoot ion concentrations in spite of the hypoxic (or anoxic) medium in which they are rooted, this being in stark contrast with most other plants which suffer when salinity and waterlogging occur in combination. Very few studies have addressed the consequences of submergence of the shoots by saline water; these have, however, demonstrated tolerance of temporary submergence in some halophytes.New Phytologist (2008) 179: 964-974

“…Nitrogen content depends on the material, its age and environmental conditions (Langlois & Ungar 1976). Under various submergence treatments, main stems and branches of young plants of inland origin (referred to S. ramosissima ) accumulated total N of 3.0–4.3% (dry mass), representing 1.8–3.0% as protein N and 1.0–2.1% as soluble N; corresponding values for S. europaea (‘ S. stricta Dumort.’) of coastal origin were total N 4.7–5.5%, protein N 1.0–4.7% and soluble N 0.4–4.5%.…”

“…It has been indicated that considerable phenotypic plasticity exists in Salicornia and that the genetic basis of diagnostic characters has to be tested experimentally (Dalby, 1955;Ball & Tutin, 1959;Langlois & Ungar, 1976;Rozema & al., 1987). Morphometric studies using all phenotypic differences available irrespective of whether they have a genetic basis or not could not reveal distinct taxa even on a small regional scale (Ingrouille & Pearson, 1987;Ingrouille & al., 1990).…”

In this study we analysed ETS sequence data of 164 accessions belonging to 31 taxa of Salicornia, a wide‐spread, hygrohalophytic genus of succulent, annual herbs of Chenopodiaceae subfam. Salicornioideae, to investigate phylogenetic and biogeographical patterns and hypothesise about the processes that shaped them Furthermore, our aim was to understand the reasons for the notorious taxonomic difficulties in Salicornia. Salicornia probably originated during the Miocene somewhere between the Mediterranean and Central Asia from within the perennial Sarcocornia and started to diversify during Late Pliocene/Early Pleistocene. The climatic deterioration and landscape‐evolution caused by orogenetic processes probably favoured the evolution and initial diversification of this annual, strongly inbreeding lineage from the perennial Sarcocornia that shows only very limited frost tolerance. The further diversification of Salicornia was promoted by at least five intercontinental dispersal events (2× to South Africa, at least 3× to North America) and at least two independent polyploidization events resulting in rapidly expanding tetraploid lineages, both of which are able to grow in lower belts of the saltmarshes than their diploid relatives. The diploid lineages of Salicornia also show rapid and effective range expansion resulting in both widespread genotypes and multiple genotypes in a given area. Reproductive isolation through geographical isolation after dispersal, inbreeding, and comparatively young age might be responsible for the large number of only weakly differentiated lineages. The sequence data show that the taxonomic confusion in Salicornia has two major reasons: (1) in the absence of a global revision and the presence of high phenotypic plasticity, the same widespread genotypes having been given different names in different regions, and (2) striking morphological parallelism and weak morphological differentiation led to the misapplication of the same name to different genotypes in one region.
