电化学阻抗谱(EIS)是一种研究有机和无机材料特性的方法，其基础是通过观察组织对外界电能传递的电响应来确定其被动的电学性质。材料的阻抗和相角由多频阻抗分析仪(阻抗计)测量，该分析仪能够以不同频率扫描每个样品。电化学阻抗已被广泛用于评估植物健康、营养状况、矿物质缺乏、病毒的存在、果实损伤、果实成熟过程中的结构细胞变化、冻害、对盐分的敏感性以及树木根系生长的测量。在这些研究中，EIS测量提供了一种非破坏性分析细胞膜内外电阻变化的手段。介绍了EIS在植物科学领域的基础研究和一些应用，特别是与根的生长发育、种子质量、环境胁迫和果实损伤或成熟有关的研究。
Electrochemical impedance spectroscopy (EIS) is a method to study the characteristics of organic and inorganic materials, based on their passive electrical properties, determined by the observation of the tissue electrical response to the passage of external electrical energy. The impedance and phase angles of the materials is measured by a multiple frequency impedance analyzer (impedance meter) that is able to scan each sample at different frequencies. Electrochemical impedance have been widely used to estimate plant health, their nutrient status, mineral deficiency, presence of viruses, fruit damages, structural cellular variation during fruit ripening, freeze or chill damages, sensitivity to salinity, and measurement of root system growth in trees. In all these studies EIS measurements provided a means of nondestructively analyzing variation in intra- and extracellular resistances and in the condition of the membranes.The fundamental studies and some applications of EIS for the field of plant science are described, particularly in relation to root growth and development, seed quality, environmental stresses, and fruits damages or ripening.
