Soil Oxidation-Reduction in Wetlands and Its Impact on Plant Functioning

摘要: Soil flooding in wetlands is accompanied by changes soil physical and chemical characteristics. These include the lowering of redox potential (Eh) leading to increasing demand for oxygen within profile as well production phytotoxins that are by-products reduction thus, imposing potentially severe stress on plant roots. Various methods utilized quantifying responses reducing conditions measurement radial transport, enzymatic responses, assessment anatomical/morphological changes. However, properties nature environment which roots grown, including demand, other associated processes occur wetland soils, pose a challenge evaluation comparison reported literature. This review emphasizes soil-plant interactions wetlands, drawing attention importance intensity capacity proper particularly at process whole-plant levels. Furthermore, while root oxygen-deficiency may partially account phytotoxins, produced low Eh conditions, discussed need development allow differentiation reduced or anaerobic vs. emphasized.
