The length of the free-running periods of circadian leaf movements in the primary and secondary pulvini of Phaseolus coccineus was measured in constant darkness (DD) and continuous light (LL) of different intensities. The periods for the two pulvini do not differ from each other in DD and LL 30000 lx. However, they differ in LL 60 lx, 600 lx and 6000 lx, indicating a state of internal desynchronization. These results show a difference in the light intensity dependence of the 2 oscillations and a lack of mutual synchronization between them.
