“…The area called El Saler or Devesa de l'Albufera, near the city of Valencia, is one of the best known botanical sites in Spain, as well as the classical site for two of the most relevant Valencian Limonium endemics, L. dufourii (Girard) Kuntze, and L. albuferae P.P. Ferrer, R.A. Rosello and E. Laguna [17][18][19][20][21][22][23][24][25]. It is located in the l'Albufera Natural Park, the most renowned protected area of the Valencian Community.…”

“…Limonium albuferae is a triploid (2n = 26), recently described as apomictic species with incompatible pollen-stigma interactions [25]. It is a perennial halophyte, multi-rosulate chamaephyte, varying from isolated rosettes (5-8 cm in width) to dense cushion-shape individuals (up to 45 cm in width) bearing tall flowering stems up to 80 cm (personal observations).…”

We have analysed the salt tolerance of two endemic halophytes of the genus Limonium, with high conservation value. In the present study, seed germination and growth parameters as well as different biomarkers—photosynthetic pigments, mono and divalent ion contents—associated to salt stress were evaluated in response to high levels of NaCl. The study was completed with an untargeted metabolomics analysis of the primary compounds including carbohydrates, phosphoric and organic acids, and amino acids, identified by using a gas chromatography and mass spectrometry platform. Limonium albuferae proved to be more salt-tolerant than L. doufourii, both at the germination stage and during vegetative growth. The degradation of photosynthetic pigments and the increase of Na+/K+ ratio under salt stress were more accentuated in the less tolerant second species. The metabolomics analysis unravelled several differences between the two species. The higher salt tolerance of L. albuferae may rely on its specific accumulation of fructose and glucose under high salinity conditions, the first considered as a major osmolyte in this genus. In addition, L. albuferae showed steady levels of citric and malic acids, whereas the glutamate family pathway was strongly activated under stress in both species, leading to the accumulation of proline (Pro) and γ-aminobutyric acid (GABA).

“…The complex of salt marshes developed in the Albufera Natural Park territory, located a few kilometres south of the city of Valencia, is of particular floristic and environmental interest (Ballester et al 2003;Soria 2006). It shelters the unique populations of endemic Limonium albuferae, only found in this area (Ferrer-Gallego et al 2016), and Limonium dufourii, which is present also in a few other salt marshes outside the Natural Park (Aguilella et al 2010).…”

Background and aims Two local threatened endemics from Valencian salt marshes were analysed from a multidisciplinary perspective combining field studies with experiments performed under greenhouse-controlled conditions. The work aimed to investigate the habitat of the two species but also to explore their limits of tolerance to severe drought and salinity and the mechanisms behind their stress responses. Methods The number of individuals in several populations, climatic conditions, soil characteristics and accompanying vegetation in the natural habitats were analysed in the field study. Plants obtained by seed germination were grown in the greenhouse and subjected to one month of water and salt stress treatments. Growth and biochemical parameters were analysed after the treatments were finalised. Results No correlation between climatic parameters and the number of individuals censed of the two Limonium species could be established. Although L. dufourii was found in more saline soils in the natural habitats, under controlled greenhouse conditions, this species was more severely affected by salt treatment than L. albuferae, which is more susceptible to water stress. A common biochemical response was the increase of proline under all stress treatments, but mostly in water-stressed plants. Oxidative stress markers, MDA and H2O2, did not indicate significant differences between the treatments. The differences in the two species' responses to the two kinds of stress were correlated with the activation of the antioxidant enzymes, more pronounced in conditions of salt stress in L. albuferae and of water stress in L. dufourii. Conclusions Although L. albuferae is found in sites with lower salinity in the natural habitats, the greenhouse experiment indicated that it tolerates higher concentrations of salt than L. dufouri, which is more resistant to drought. The two species efficiently mitigate oxidative stress by activation of antioxidant enzymes. The results obtained may be helpful for the conservation management of the two species: whereas salinity is not problematic, as the two species tolerated under controlled conditions salinities far beyond those in their natural environments, water scarcity may be a problem for L. albuferae, which proved to be more susceptible to water deficit.
