Abstract
This article deals with measurement techniques of water conducting system in the trees.
Water conducting system (including xylem and phloem) indicates its importance for related physiological processes.
However, there are still problems how to measure its functioning (which variables and how), especially in the open field (e.g., forests and orchards) in order to get maximum information about it.
In this study we focused on a general description of acoustic events measurable in a wide range of their spectrum (acoustic emission method). The first aim was to detect such signals and the second to learn them and gradually analyze in order to better understand the associated processes causing their occurrence and their relations to plant life.
