First bioimpedance assessment for detecting eects caused by environmental stimuli on Grapevine (Vitis vinifera L.): preliminary results

Abstract

Plants comprise biological tissues where bioimpedance could be measured.Changes in values of these impedance parameters within tissues are the result of changes inthe chemical composition of the sap, cellular depolarization, and ion transport in response toexternal stimuli such as water availability, diseases, and photosynthesis activity, among others.Therefore, the environmental eects on the plant change its morphology and physiology wouldbe related to bioimpedance. In this way, bioimpedance could become a novel and powerfultechnique used to analyze, in-situ and in real-time, the physiologic activity and status. In thisstudy, we assess the Evaluation Board AD5933EBZ as a bioimpedance low-cost measurementdevice to perform observations of module and phase of the bioimpedance, aimed to correlatethem with the eects of environmental stimuli such as irrigation, CO2 concentration, sunexposure and temperature level in the grapevine.
