Abstract

In this work we report a novel method that can monitor in vivo the salt permeation process into a plant Vigna angularis using two Ag/AgCl electrodes. The method is based on the electromotive force (emf) measurement using two Ag/AgCl electrodes, one inserted into the V. angularis pith cavity and the other placed into saline ([NaCl]=1 M) surrounding the roots. Temporary change of emf ranging from 0 to ca. 0.115 V was measured in vivo using the system, and the possible physiological phenomenon during the period was discussed.

摘要

在本研究中，我们报告了一种新颖的方法，该方法可使用两个Ag/AgCl电极在体内监测盐分渗透到豇豆中的过程。该方法基于使用两个Ag/AgCl电极测量电动势（emf），一个电极插入豇豆的髓腔中，另一个置于根部周围的盐溶液（[NaCl]=1 M）中。使用该系统在体内测量到电动势的临时变化范围为0至约0.115 V，并讨论了在此期间可能出现的生理现象。
