“…However, Sa. emerici is a Mediterranean annual halophyte with few and erect branches that colonize low salt marches that are often ooded and its seed dissemination is in late autumn (Hayder et al 2022). In their natural habitat, plants are not only affected by salt stress but also by T uctuation.…”

Quantification of germination niches under salt stress, temperature, and their interaction using population-based threshold models is important to predict seedling emergence patterns. Seeds of Sarcocornia fruticosa, Sarcocornia alpini, and Salicornia emerici were treated with various temperatures at different NaCl concentrations. Results indicated that the median base NaCl concentration was roughly steady (0.68, 0.73, and 0.70M, respectively) at sub-optimal temperature, then decreased linearly at supra-optimal temperature until the ceiling temperature (Tc). The estimated base, optimum and ceiling temperatures, in water, were − 0.5, 15 and 29°C for Sarcocornia fruticosa, − 2.5, 11 and 24°C for Sarcocornia alpini, and 9.5, 25 and 40°C for Salicornia emerici, respectively. At all species, the base temperature has not changed with the salinity while both optimum and ceiling temperatures decreased. Also, Salicornia emerici showed rapid and synchronized germination when salinity decreases during the rainy season coinciding with favorable temperatures compared with other species.

Aerial biomass of the edible halophyte species Salicornia emerici Duval-Jouve and Sarcocornia alpini (Lag.) Rivas Mart. (Amaranthaceae), collected from southern Tunisia, were investigated as potential sources of functional ingredients. For that purpose, dried biomass was profiled for proximate and mineral composition, and its hydroethanolic extracts were analyzed for phenolics contents by spectrophotometric and chromatographic (HPLC-ESI-MS) methods. The extracts were then profiled for in vitro antioxidant properties (radical scavenging activity (RSA) of DPPH and ABTS radicals, and ferric reducing power (FRAP)), cytotoxicity, and enzymatic inhibition toward enzymes related with human diseases, namely acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) (Alzheimer´s disease: AD), α-amylase and α-glucosidase (type 2 Diabetes Mellitus: T2DM), and tyrosinase (skin hyperpigmentation disorders). Biomass had relevant levels of minerals, especially sodium, potassium and iron. The extracts were not toxic, contained various bioactive phenolic compounds, such as naringin and quinic acid and exhibited relevant FRAP and inhibition properties against α-glucosidase and tyrosinase. Our findings suggest that there is potential to further explore the biomass from S. alpini and S. emerici as safe and sustainable sources of nutrients and of natural products with antioxidant, anti-diabetic and anti-tyrosinase properties, which might yield significant economic benefits for the southeastern region of Tunisia.

Background Detailed studies were conducted for the first time on the floral anatomical features, anther development, megasporogenesis, embryological stages, and seed anatomical characteristics of S. fruticosa, S. alpini, and S. emerici. These species were recently identified in Tunisia through a molecular study.Methods Histological sections, observations using a light microscope, and photographs were taken.Results The results indicate that the pollen grains are characterized by a pantoporate structure of predominantly spheroidal shape. The ovary takes on an annular shape and then curves to produce a campylotropic ovule. After fertilization, the nucellus gives rise to the perisperm, which is absent in mature seeds. The mature embryo exhibits a horseshoe shape and occupies almost the entire seed. The filament length, the size of the anther, pollen, ovary, style, stigma, and seed were the most developed in S. fruticosa. The radicle is longer than the cotyledons in S. emerici, whereas they are of the same length in the other two species. Regarding seed ornamentation, S. fruticosa exhibits a verrucate exotesta with short hairs and papillae that have a blunt tip. However, in S. alpini, it shows a higher density of papillae with a round and conical apex. In S. emerici, the seed surface is covered with numerous long hairs.Conclusion To our knowledge, this is the first contribution, as these species had not been previously examined. Furthermore, the findings related to megasporogenesis, female gametophyte, and embryonic development provide evidence that further studies are required for a better anatomical characterization of the Salicornia/Sarcocornia genus.
