Abstract. Fluence-response and reciprocity data were collected for response to end-of-day FR in several light-grown plants. Coleoptile elongation in oat and hypocotyl elongation in sunflower and mung bean are stimulated by end-of-day FR, and anthocyanin accumulation in mung bean hypocotyls is decreased by the same treatment. All responses have threshold fluences at about 200μmol m−2 and saturation fluences between 4000 and 10,000 μmol m−2 Responses to end-of-day FR were reversible by subsequent R with threshold fluences between 2.0 and 3.0 μmol m−2 and saturation fluences between 300 and 1000 μmol m2 Rapid, reverse reciprocity failure which could not be explained by escape from photoreversibility was observed only for stimulation of oat coleoptile elongation by end-of-day FR. Oats also showed apparent reverse reciprocity failure for R, but it was entirely explainable by escape. Rapid, reverse reciprocity failure is not a ubiquitous phenomenon for responses to end-of-day irradiations.
