Popis: Summary The length of every primary cell (= cell issued from the division of an apical cell) from young protonema of Ceratodon purpureus is closely related to instantaneous speeds of elongation and mitosis of the filament. Under constant conditions (continued light or darkness) these different parameters present non periodic aleatory fluctuations. On the contrary, photo periodic conditions (12 h) induce a circadian rhythm of these characteristics.
