Abstract

Vegetative reproduction is an important phenomenon in the propagation of Gelidium species, having significant implications for its ecology and commercial cultivation. This work is an experimental study of one of five sequential processes included in the vegetative propagation of Gelidium sesquipedale: the reattachment of rhizoidal filaments differentiated from apical fragments.

Two different factors: light (25 µmol m−2 s−1 and long-day conditions, and 50 µmol m−2 s−1 and short-day conditions) and life history phases (female gametophytes and tetrasporophytes) were combined in a 2 × 2 factorial experiment. Reattachment of apical portions was induced in the laboratory under spray cultivation conditions and occurs mainly at the first stage of development when in contact with the substratum. Light conditions in these experiments (photoperiod + instantaneous photon flux densities) had no effect on the percentage of reattached neofilaments per fragment. Significant differences between percentages corresponding to both phases suggest, however, a probable competitive advantage of sporophytic fronds.
