Karyotypes and microfluorometric studies in Porphyra columbina Montagne (Bangiales, Rhodophyta), with reference to morphology and sexuality

Ten morphotypes attributed to different species of Porphyra have been found in the central coast from Chile. In this paper we report the chromosome number and microfluorometric studies in P. columbina from Montemar, Chile (32°57'S - 71°33'W). Reproductive gametophytes from two morphotypes...
