| 内容記述 | Previous reports by Migita (1967) and Giraud & Magne (1968) showed that the meiosis appears in the cell of conchosporangium in Porpyra, but the detail figures about the process of the meiosis has not been clear. The purpose of this paper is to investigate cytologically the process of the meiosis in three species of Porpyra, P. pseudolinearis, P. tenera and P. yezoensis in more detail, especially dealing with free-living form in vitro. In the carpospore-germlings diploid chromosomes are observed in their first cell division in P. pseudolinearis and P. tenera as in P. yezoensis reported by Kito (1967). In the filamentous somatic cells diploid mitotic nuclear division appears in all of the three species. In the cell of the conchosporangium diploid chromosomes are observed also, and meiotic nuclear division is recognized by its characteristic phase of chromosomes in their maturing ones. As for P. pseudolinearis maturing conchospoagial branches form the uniserious cells, however in P. tenera and P. yezoensis, they are often divided by a longitudinal plane twice or more. The pit-connection is clearly observed even between the cell of maturing sporangial cells in the three species. As for P. pseudolinearis the carpospore-germlings immediatly after germinating shows a pear-shape with a primary thick germinate tubu, and then, a thin germinate tubu develops secondarily from the top of the first tubu. The first nuclear division after germinating appears in the primary or secondary germinate tubu. On the other hand, a thin germinate tube develops directly from the original spore and the first nuclear division appears in the original spore in P. yezoensis and P. tenera. | |||||
