DARK TRIGGER. “The time of the onset of darkness, however, had a large effect on the rhythm. In plants grown in the field and brought into 12 h darkness, starting at 12 noon, the flowers from then on showed a 24 rhythm whereby they followed the new cycle. Normally all flowers on a plant opened and closed at the same time. However, if buds on the same plant were placed in darkness at various times, they opened and closed at different times, set by the time of the onset of continuous darkness.”
