Change in dark-sensitivity of a long-day duckweed, Lemna, gibba G3, under varied photoperiodic conditions was studied. When photoperiod shorter than 12hr was given to phase I (the first half of the first cycle) or a short-day was given as the first cycle, the sensitive system to light interruption appeared in phase II(the second half of the first cycle), and the inhibition of flowering caused by darkened phase III(the first half of the second cycle) could be alleviated by light interruption given to darkened phase III. In other words, the phase in which the sensitive system was most active was different from the phase in which this system actually worked. This system could also enhance the function of the light period given to the first half of the next cycle. Probably owing to this mechanism, the long-day plant can flower when the nyctoperiod of short-day regime to which the plant is subjected is interrupted by light.
