Electrical impedance

Some relationship exists between frost hardiness, dormancy and electrical impedance, however, the extent of these relationships is difficult to determine. In general, electrical impedance measures the ionic or electrolytic content of the tissues, which in turn reflects their metabolic activity. The higher the ionic content, the lower the electrical impedance and the higher the metabolic activity. Conversely high impedance means low ionic content and low metabolic activity. Metabolic activity in turn is related to dormancy and frost hardiness. This is an oversimplification of the relationships, but will serve the purpose here.
