中文摘要:
      电阻抗谱法作为植物生理学研究的一种方法袁把植物组织看作一个等效电路,电阻抗谱参数的变化可以反应植物组织的生理学变化,表征植物细胞膜透性变化。通过研究电阻抗谱参数与植物细胞膜透性相关生理指标之间的关系,描述植物生理状态,具有方便、快捷、非破坏性等特征。近年来,电阻抗谱法在植物膜透性相关生理学研究中的应用正在不断扩大。因此,对电阻抗谱法在植物细胞膜透性生物学领域的逆境胁迫、果实成熟、蔬菜贮藏、嫁接成活和根系形态等方面的研究进展进行了综述。
英文摘要:
      Electrical impedance spectroscopy, as a method of research in plant physiology, treats the plant tissue as an equivalent circuit. The changes of electrical impedance spectrum parameters possibly reflect the physiological changes of plant tissue and characterize the changes of plant cell membrane permeability. By exploring the relationship between electrical impedance spectrum parameters and relevant physiological indexes of the plant cell membrane permeability, electrical impedance spectroscopy indicates the plant physiological state with the features of convenient, fast and non-destructive. And its application in plant physiological aspects of plant cell membrane permeability has a tendency to widely in recent years. This paper reviewed the applications of electrical impedance spectroscopy so far in plant adversity stresses, fruit ripening, vegetable storage, graft survival and root morphology, etc.
