“…water in succulent aerial parts, the intercellular sequestration of toxic ions and the synthesis and accumulation of compatible solutes and osmolytes (Nikalje, Bhaskar, Yadav, & Penna, 2019;Rozentsvet, Nesterov, & Bogdanova, 2017). Halophytes represent an alternative to traditional crops (Nikalje, Srivastava, Pandey, & Suprasanna, 2018;Petropoulos, Karkanis, Martins, & Ferreira, 2018) and are also useful biological models for the understanding of tolerance mechanisms and stress responses in traditional salt-sensitive plants (Srinivas et al, 2018).…”

The halophyte species Salicornia ramosissima has long been consumed as food and is currently regarded as a high-value gourmet item. However, given that these plants grow in estuarine areas, often impacted by pollution, and are prone to the accumulation of ions, the risks associated with food borne pathogens or toxic metals has to be carefully considered. The objective of this work was to gather evidence that S. ramossissima harvested locally in an estuarine system (Ria de Aveiro, Portugal) can be safely consumed as a healthy and catering-amenable food. Fresh shoots, taken as green vegetables, and dried powdered shoots (green salt) intended as seasoning, were analysed for total aerobic bacteria, total coliforms, Escherichia coli, Bacillus cereus and fungi (yeasts and moulds). The nutritional profile and the concentration of macro and micro elements, including potential toxic elements, was also established.Fresh shoots and green salt were incorporated in catering meals (soup and a meat dish) and subjected to sensory analyses. The microbiological quality of fresh shoots and green salt was compliant with the guidelines for salad greens and herbs and spices, respectively. The nutritional and elemental profile revealed that fresh shoots have a high content in fibre and NaCl. From the concentration of Na determined in green salt, a daily dose of 7 g was estimated as corresponding to the recommended daily dietary intake Na. None of the other elements was present in concentrations that could exceed the dietary intake limits. In the sensory tests, fresh shoots were well accepted as salad greens but green salt, used as seasoning, was considered as insufficient in terms of saltiness and does not completely substitute cooking salt. The results confirm the nutritional and sensory value of S. ramossisima and represent a promising prospect for the incorporation of locally harvested or crop cultivated plants in catering meals.

“…However, increasing salinity triggered the gradual accumulation of Na in shoots. As increasing salinity stress deteriorated the functioning of the photosynthetic apparatus, it can be proposed that storage of excessive Na in vacuoles (adaptive mechanism of some halophytes 45 ) is probably not efficient in R. acris . The most likely mechanism responsible for the transportation of Na to aerial organs is uncontrolled entrance of ions via bypass flow in Casparian strips of endodermis 47 followed by compulsive xylem loading.…”

Ranunculus acris L. is a native species widely distributed throughout Europe and is invasive in nonnative areas, causing substantial economic losses in pasture productivity. The present study examined the effects of sodic salinity on the growth and functioning of this species. Salinity stresses the germination process and seedling growth, indicating that the studied species experience serious limitations at 60–90 mmol dm−3 NaCl and cannot establish in habitats where salinity is equal to or greater than 150 mmol dm−3 NaCl. R. acris is tuned to subsaline habitats characteristic of temperate meadows, as its growth and functioning were the best when the plants were treated with 30 mmol dm−3 NaCl. Increasing salinity (60 and 90 mmol dm−3 NaCl) hampered growth, leaf morphology and photosynthesis but not mineral nutrition, as Na accumulation seemed to be the most outlined effect of NaCl application. Changes in leaf morphological characteristics coordinated well with Na content in those organs, which indicates that leaf appearance can be easily catchable sign of progressing salinity. Ultimately, progressing salinity reduces the competitiveness of the studied species, shifting its strategy to ruderal behavior, but under subsaline conditions, the strategy of this species seems to be most balanced.

“…Moreover, in both glycophytes and halophytes, salinity conditions are often correlated with an increased WUE. In glycophytes, the increased WUE in salinity conditions has been related to a reduced stomatal conductance (Atzori et al 2016) and to decreased water consumption (Atzori et al 2019), whereas in halophytes, i.e., A. tricolor and A. cruentus, the increased WUE was due to reduction in stomatal density (Srinivas et al 2018).…”
