1. The rhythm of sensitivity to light interruption in a long-day duckweed, Lemna gibba G 3, was examined. The rhythm was circadian and was suggested to be under the control of a physiological clock. Light given in the trough between the first and second peaks reset the rhythm. Five to 7 cycles of non-circadian photoperiodic regimes given entrained the rhythm to external periodicity, and this entrained rhythm persisted even after the plants were transferred to continuous darkness. 2. It was suggested that the induction period is not determined by the physiological clock disclosed here, but by a periodic alternation of dark-sensitivity, or by a periodic change in activity of SS (system sensitive to IPEF, induction period extending factor,) as postulated previously.
