Electrophysiological characteristics of undergrowth shrubs in the forest-steppe zone of western Ukraine

Abstract

The article reviews the electrophysiological characteristics of pre-cambial phloem material in undergrowth shrubs. The electrophysiological properties of hazel (Corylus avellana L.), elder (Sambucus nigra L.) and other undergrowth shrubs are compared, as well as how these characteristics change depending on stand density indices. Differences in electrophysiological characteristics reveal the crucial role of light for the growth, development and persistence of undergrowth shrubs. I suggest that a quantitative assessment of electrophysiological characteristics should be undertaken when managing forest stands for the creation of desirable undergrowth.
