The influence of electrical charge and indolebutyric acid on rooting of willow cuttings

R. Domański, C. Lesiewicz, S. Poliszko, S. Surma


Willow cuttings were treated by direct electrical current (DEC), with a negative or a positive electrode inserted inside them, and with the other being outside. Both directions of DEC flow between electrodes stimulated rooting as actively as growth stimulators. The mung bean or oat coleoptile straight growth test showed that the cuttings released some growth promoters into the surrounding water. However, the simultaneous release of some undetected rooting inhibitors was not excluded. The experiment, shows the possibility of changing the chemical regulatory mechanisms of tissues by the use of weak, direct electrical current which causes, the migration of particular substance{s) into or from a definite tissue or organ.
