ABSTRACT Electric potential differences in living plants are explained by theories based on sap flow. In order to acquire more advanced knowledge about the spatial distribution of these electric potential measures in trees, this research aims to analyze electrical signals in a population of Aleppo pines (Pinus halepensis Mill.) in a representative Mediterranean forest ecosystem. The specific research objective is to assess some of the most significant factors that influence the distribution pattern of those electric signals: tree age, measurement type and electrode placement. The research has been conducted in representative forest stands, obtaining measurements of different representative trees. After a statistical evaluation of the obtained results, the main conclusions of our research are: A.Tree maturity influences directly on electric potential. B.Maximum electrical signals can be measured in young pines showing values of 0.6 V and 0.6 µA for voltage and current, respectively. C.The distribution patterns of both voltage and short-circuit current depending on electrode placement are uniform.

地中海森林生态系统中松树的电信号评估

摘要 基于树液流的理论解释了活植物的电势差。为了获得有关树木中这些电势测量的空间分布的更高级知识，本研究旨在分析代表性地中海森林生态系统中阿勒颇松树（Pinus halepensis Mill.）种群的电信号。具体的研究目标是评估影响这些电信号分布模式的一些最重要的因素：树龄、测量类型和电极放置。该研究在代表性林分中进行，获得了不同代表性树木的测量结果。在对所得结果进行统计评估后，我们研究的主要结论是： A. 树木成熟度直接影响电势。B. 可以在年轻的松树中测量最大电信号，电压和电流的值分别为 0.6 V 和 0.6 µA。C.电压和短路电流取决于电极放置的分布模式是均匀的。
