Halophyte is a distinctive group of plants that can survive, even well flourish, at a concentration of Na⁺ and Cl⁻ ions along with heavy metals that would be lethal to most of the agricultural crop species. These capabilities make certain halophytes good contenders for phytoremediation through phytoextraction or phytostabilization of the salt and heavy metals (HMs) in polluted soils. Thus, the present study elucidates the phytoextraction capacity of three halophytes (Suaeda monoica, Tamarix indica and Cressa critica) growing in saline soil (EC 112 ds m⁻¹), with higher level of HMs rather than a cultivated soil. The accumulation of ions in above-ground tissue was determined in the all three studied plants, considering the fact that maintaining a stable cytosolic Na⁺/K⁺ ratio has become a crucial salinity tolerance mechanism. The higher salinity of soil resulted in high level of Na⁺ ions in leaves, increased synthesis of osmolyte components and robust antioxidant activities to combat the oxidative stress. As whole, changes in cellular metabolites were determined by using FT-IR spectroscopy, evident as differential FT-IR profiles in both leaves and stem specific to these metabolites. The considerable amounts of HMs accumulation including Zn, Fe, Mn, Cu, Cr, and Cd with highest being Fe in above-ground tissue of all three studied halophytes were obtained. These preliminary findings represent S. monoica, T. indica and C. cretica as potent phytoremediation plant using phytosequestration to accumulate HMs. The present study project a light on the use of these three plants in reclamation of degraded saline soils.

盐生植物是一种独特的植物群，在 Na ⁺和 Cl ^-离子以及对大多数农作物物种具有致命性的重金属浓度下，它们可以存活，甚至茁壮成长。这些能力使某些盐生植物成为通过植物提取或植物稳定污染土壤中的盐和重金属 (HMs) 进行植物修复的有力竞争者。因此，本研究阐明三种盐生植物（植物提取的容量碱蓬同丝水霉，柽柳籼稻和Cressa CRITICA）在盐水土壤生长（EC 112 DS中号^-1)，具有更高水平的 HMs 而不是耕作的土壤。^{考虑到维持稳定的胞质 Na +} /K ⁺比率已成为关键的耐盐机制这一事实，在所有三种研究植物中测定了离子在地上组织中的积累。土壤盐分较高导致Na ⁺叶中的离子，渗透质成分的合成增加和强大的抗氧化活性以对抗氧化应激。总体而言，细胞代谢物的变化是通过使用 FT-IR 光谱法确定的，这在叶片和茎中对这些代谢物具有特异性的差异 FT-IR 谱很明显。在所有三种被研究的盐生植物的地上组织中都获得了大量的 HMs 积累，包括 Zn、Fe、Mn、Cu、Cr 和 Cd，其中 Fe 含量最高。这些初步发现表明S. monoica、T. indica和C. cretica作为有效的植物修复植物，使用植物隔离来积累 HMs。本研究旨在阐明这三种植物在退化盐渍土开垦中的用途。
