In the context of chronobiological research on trees, a high-sensitivity device was developed to measure low-potential electric currents along the bole of two trees growing under open conditions. Rhythmic variations of the (bio-)electric potentials are found, linked on the one hand to daily photoperiods and on the other to lunar periodicities, depending on the physiological phase of the trees.
