• Under a photoperiodic regime of 12-hr light and 12-hr dark (12L-12D) and continuous illumination (24L-0D), at 24.0+__-1℃, the rate of elongation of the rhizoid cluster was 8.1 mm/day, and the presumptive site of the cluster initiation was 1.1-1.9 mm from the rhizome tip. However, the plastochron interval under 24L-0D regime was shorter (0.87 day) than under 12L-12D regime (1.18 days). Under both regimes, the plants tended to adjust their presumptive time of cluster initiation to be in the two periods of the day, 0400-0900 hr and 1800-2100 hr. None of the following seemed to correlate with the initiation of a new cluster : a certain number of hours after the initiation of the youngest cluster, a certain distance on the rhizome distal to the youngest cluster, the youngest cluster reaching to a certain length, or a certain value of the rhizoid plastochron index. This adjustment by the plants thus suggested the plants having an ability to perceive the two preferred periods for cluster initiation.
