Abstract:
The inhibition of flowering in chrysanthemum by cyclic or continuous illuminations in the middle of the night was studied with mixed red/far red (incandescent) and pure red light at different intensities. Although cyclic lighting greatly enhanced the flower‐inhibitory capacity of mixed red/far red light, no such effect was obtained with pure red light. It is argued that the “dark reversion” hypothesis is not adequate to explain the differential effectiveness of cyclic lighting. A possible mechanism is suggested by which mixed red/far red light may produce more Pfr by interrupted than by uninterrupted illuminations.
