摘要
植物盐碱化是应对盐碱土壤挑战的一种环境可持续解决方案,涉及到耐盐植物的鉴定。本研究对泰国孔敬(Khon Kaen)地下盐穹附近的铁线蕨(Fimbristylis ferruginea)和佃蕨(Fimbristylis tenuicula)进行了细致的研究,揭示了独特的土壤理化性质、形态、代谢组学反应和离子螯合机制。尽管铁线蕨的ECe较低(21.79 dS m-1,而tenuicula为41.46 dS m-1),但它在固钠方面却表现出色(504.42 g kg DW-1,而tenuicula为246.32 g kg DW-1)。Fimbristylis ferruginea 的根系在盐度胁迫下能有效锁住钠,这主要得益于青花素、鹅掌楸素和脯氨酸相容溶质。相反,在同一属和同一环境中,F. tenuicula 对盐度胁迫的反应是拉长根和茎,加强盐分储存,增加叶绿素 a 含量。生物浓缩因子和易位因子的计算结果表明,F. ferruginea 具有植物稳定作用,F. tenuicula 具有植物萃取作用。这项研究强调了对两种 Fimbristylis 植物耐盐性的评估,这两种植物可作为具有低成本影响的天然盐库。值得注意的是,铁线蕨(F. ferruginea)占优势,在其生物量中储存了高达 50%的钠。
Assessment of salt tolerance in phytodesalination candidates: Two varieties of Fimbristylis—F. ferruginea and F. tenuicula
Phytodesalination, an environmentally sustainable solution for saline soil challenges, involves identifying salt-tolerant plants. This study meticulously examined Fimbristylis ferruginea and Fimbristylis tenuicula near the underground salt dome in Khon Kaen, Thailand, revealing unique physicochemical soil properties, morphology, metabolomic responses, and ionic sequestration mechanisms. Despite F. ferruginea’s lower ECe (21.79 vs. 41.46 dS m−1 for F. tenuicula), it excelled in sodium sequestration (504.42 g kg DW−1 vs. 246.32 g kg DW−1). Fimbristylis ferruginea’s roots efficiently locked sodium, facilitated by cyanidin, pelargonidin, and proline—compatible solutes crucial under salinity stress. Conversely, F. tenuicula, within the same genus and environment, responded to salinity stress by elongating roots and stems, enhancing salt storage, and increasing chlorophyll a content. Bioconcentration factor and translocation factor calculations designated F. ferruginea for phytostabilization and F. tenuicula for phytoextraction. This research emphasizes the assessment of salt tolerance in two Fimbristylis species, serving as natural salt reservoirs with low-cost implications. Remarkably, F. ferruginea dominated, storing up to 50% sodium in its biomass.
期刊介绍:
Articles in JEQ cover various aspects of anthropogenic impacts on the environment, including agricultural, terrestrial, atmospheric, and aquatic systems, with emphasis on the understanding of underlying processes. To be acceptable for consideration in JEQ, a manuscript must make a significant contribution to the advancement of knowledge or toward a better understanding of existing concepts. The study should define principles of broad applicability, be related to problems over a sizable geographic area, or be of potential interest to a representative number of scientists. Emphasis is given to the understanding of underlying processes rather than to monitoring.
Contributions are accepted from all disciplines for consideration by the editorial board. Manuscripts may be volunteered, invited, or coordinated as a special section or symposium.
