“…Previous studies have shown that salt concentration and composition can influence the growth of halophytes [9,[28][29][30][31]. The differences in growth between treatment and control groups are potentially the result of the lower chloride content in the control solution enabling higher biomass production.…”

“…Previous studies using S. europaea have already investigated how saline water affects growth, germination, and seed quality as well as demonstrated successful cultivation with seawater, sodium chloride solutions, brackish, or waste water, thereby highlighting S. europaea as a suitable model plant to test natural brines in this case study [8,9,[28][29][30][31][32]. However, to date, none of these studies have addressed cultivation with natural brines.…”

Scaling agriculture to the globally rising population demands new approaches for future crop production such as multilayer and multitrophic indoor farming. Moreover, there is a current trend towards sustainable local solutions for aquaculture and saline agriculture. In this context, halophytes are becoming increasingly important for research and the food industry. As Salicornia europaea is a highly salt-tolerant obligate halophyte that can be used as a food crop, indoor cultivation with saline water is of particular interest. Therefore, finding a sustainable alternative to the use of seawater in non-coastal regions is crucial. Our goal was to determine whether natural brines, which are widely distributed and often available in inland areas, provide an alternative water source for the cultivation of saline organisms. This case study investigated the potential use of natural brines for the production of S. europaea. In the control group, which reflects the optimal growth conditions, fresh weight was increased, but there was no significant difference between the treatment groups comparing natural brines with artificial sea water. A similar pattern was observed for carotenoids and chlorophylls. Individual components showed significant differences. However, within treatments, there were mostly no changes. In summary, we showed that the influence of the different chloride concentrations was higher than the salt composition. Moreover, nutrient-enriched natural brine was demonstrated to be a suitable alternative for cultivation of S. europaea in terms of yield and nutritional quality. Thus, the present study provides the first evidence for the future potential of natural brine waters for the further development of aquaculture systems and saline agriculture in inland regions.

“…Wang et al ( 2021) [145] performed metabolomic characterization of the leaves of S. europaea, and discovered 694 metabolites involved in the tolerance to salt conditions: flavonoids, alkaloids and coumarins, and the branched chain amino acids, glucosamine, maltose, and glucose. At a high salt concentration (500 mM NaCl), the succulence is due to the Na + content of the cell, which promotes the osmotic adjustment and increases the proline and other osmolyte content, maintaining cell turgor [146]. The first investigation on the effects of salt stress in S. europaea was elucidated in 2009 [147] by looking at the growth parameters, free proline content, ion accumulation, lipid peroxidation, and several antioxidative enzymes activities of in vitro plantlets.…”

Biological and Agronomic Traits of the Main Halophytes Widespread in the Mediterranean Region as Potential New Vegetable Crops

Salinity is one of the oldest and most serious environmental problems in the world. The increasingly widespread salinization of soils and water resources represents a growing threat to agriculture around the world. A strategy to cope with this problem is to cultivate salt-tolerant crops and, therefore, it is necessary to identify plant species that are naturally adapted to high-salinity conditions. In this review, we focus our attention on some plant species that can be considered among the most representative halophytes of the Mediterranean region; they can be potential resources, such as new or relatively new vegetable crops, to produce raw or minimally processed (or ready-to-eat) products, considering their nutritional properties and nutraceuticals. The main biological and agronomic characteristics of these species and the potential health risks due to mycotoxigenic fungi have been analyzed and summarized in a dedicated section. The objective of this review is to illustrate the main biological and agronomical characteristics of the most common halophytic species in the Mediterranean area, which could expand the range of leafy vegetables on the market.

“…However, the presence of salts may not always be detrimental to all crops (Table 3); some species require salts from the germination stage [5,11]. In halophytic plant types such as S. salsa, the prolonged absence of NaCl inhibits development and affects seed quality; as a consequence, it limits the growth of progeny seedlings in terms of biomass and seed yield [76,81]. In C. quinoa and S. aralocapsica with 0.3 M NaCl and 1.5 M NaCl, the percentage of seed germination is reduced between 10 and 20% [5,11,69].…”

Plant seeds, being sessile, are simultaneously exposed to favorable or adverse conditions from sowing to harvest. The physiological quality of the seed is affected by the type of biotic and abiotic stress to which the mother plant is exposed, especially in the stages of embryogenesis, development and seed filling. Therefore, the behavior of their progeny will be reflected when the seeds are capable of maintaining acceptable viability standards with a high-germination potential to generate a normal seedling and establish themselves without difficulties under field conditions. Most of the species cultivated under abiotic stress conditions reduce their physiological quality; however, some species are salt dependent, and prolonged absence of NaCl in the soil inhibits seed development, results in lower seed quality and thus limits progeny-seedling growth as is the case of Suaeda salsa, and typical annual extreme halophytic herb with succulent leaves develops well and produces high-quality seeds when grown under high salinity conditions. Consequently, the response of the plant to adverse factors depends on the genotype and its stage of development at the time of stress, the duration and severity of the type of stress and the environmental factors that cause it. Depending on the severity and duration of the stress, plants could activate mechanisms to adapt or tolerate abiotic stress conditions at the molecular, morphological, physiological and cellular levels.
