Brief exposures to red light induce far red-reversible changes of 5 to 10 millivolts magnitude in the upper 1 centimeter of etiolated Avena coleoptiles. The changes begin within 15 seconds of the start of illumination and they continue for at least 12 minutes. The changes were measured using a flowing solution of 10 mm KCl to contact the surface of the coleoptile. A dark-grown coleoptile shows no change in response to far red light unless it first receives red light treatment. The second of two red light exposures is ineffective without an intervening far red treatment. Some characterization of these electric responses to light is presented.
