Shift in Metabolite Profiling and Mineral Composition of Edible Halophytes Cultivated Hydroponically Under Increasing Salinity

These findings reveal that different shifts in osmolytes, mineral elements, and biomass accumulation in tested halophytes indicate species-dependent osmotic adjustment to increased salinity and may be attributed to the morphological differences among halophytic grasses, dicot halophytes, and those with succulent leaves or stems. The PCA score scatterplot results excluded the response of <i>Plantago coronopus</i> from other tested halophytes; also, it demonstrated that <i>Portulaca oleracea</i> was more sensitive to the hydroponic solution salinity compared to <i>Salsola komarovii</i> and <i>Plantago coronopus</i>.
