A bstract Experiments with Salvia occidentalis , a short‐day plant, showed that red nightbreak light which normally is effective in causing a long‐day effect, can under certain conditions antagonize the long‐day effect of a supplemental light period, thus causing a short‐day effect. This short‐day effect of nightbreak light disappears when the length of the nightbreak period is increased or when it is followed by an irradiation with far red (‐= near infra red).
