Impedance Spectroscopy in Frost Hardiness Evaluation of Rhododendron Leaves

Effect of bark stripping on the electrical impedance of Quercus suber leaves

“…e occurrence of one arc in a typical impedance spectrum for the leaves and the satisfactory t of the single DCE model strongly indicate the suitability of the model in the study of leaves. is result is in agreement with the previous studies of olives leaves (Mancuso 1999), Rhododendron leaves (Väinölä and Repo 2000) or of silver birch leaves (Repo et al 2004).…”

“…Several stressors a ect the EIS parameters of plants organs. e τ and the R i correlate with cold hardening in Scots pine, R e and τ decreases with increases in cellular injuries caused by frost (Repo et al 1994), the R e correlates with frost-expose in rhododendron leaves (Väinölä and Repo 2000).…”

“…EIS has been used to study stress reaction in plants (Repo et al 1994Väinölä and Repo 2000;Laarabi et al 2005aLaarabi et al , 2005b. e method provides information about the physicochemical properties of cellular structure.…”

“…erefore, information about di erent tissues features, i.e., intra and extracellular uids may be revealed by EIS (Väinölä and Repo 2000). Several stressors a ect the EIS parameters of plants organs.…”

Frequency response modelling of maritime pine (Pinus pinaster L.) wood at low frequencies

“…It has been proved in several previous studies that the frequency response of biological tissues [15,16,17,18,20] such as wood cannot be adjusted using simple elements such as resistances (R), capacitances (C), inductances (L) or diffusion impedances. This frequency dispersion is often described as a change in capacitance and is expressed in terms of Constant Phase Elements (CPE):…”
