Abstract
The reproductive pattern of Porphyra sp. was observed in laboratory culture. The thalli obtained from both natural populations and from cultures were monostromatic and reniform, obovate to linear-oblanceolate. Under the different culture conditions, no differentiation of sexual cells, spermatia or carpogonia, was observed; propagation occurred by archeospore formation (sensu Magne, 1991), with bipolar germination. Thirty successive generations have been obtained in culture, at temperatures of 12 °C and 15 °C, and each time a laminar gametophytic thallus was produced. It is concluded that Porphyra sp. has a strictly asexual reproductive pattern. This is interpreted as a reproductive adaptation to its epiphytic life form.
