In Lupinus shoots an electrical stimulus (DC) produces a voltage wave identical in character to the action potential wave (AP) in stimulated simple plant cells or in nerves and muscles. This fact served as basis for investigations undertaken to establish whether the dependences, known in neurophysiology as Pflüger's laws of contraction, are also true in the case of plant stimulation. Experiments were performed both in a system analogous to that of Pflüger (Variant I), and in more varied system (Variant II). The validity of these laws in plants has been fully confirmed. Other investigations (Paszewski and Zawadzki 1973a, 1973b, 1974) showed that such laws as the strength-duration relation and the all-or-nothing law prove correct in plants
