Abstract
Light transmission was studied at hourly intervals for 14 days on 2 intact and 4 rhizoidless (enucleated) cells first; 5 more intact and 2 rhizoidless cells were subsequently added with data covering 12 to 14 days. Each data series was analyzed by linear-nonlinear rhythmometry. On the average, enucleation was associated with a lengthening of the circadian period and a decrease in the circaseptan-to-circadian amplitude ratio. A shortening of the infradian period is also suggested. These results, originally reported for the first 6 series analyzed, are confirmed herein after the addition of 7 series from Acetabularia cells. A subtractive coupling between circadian and circaseptan components in the as-yet too-small sample remains to be further examined.
