Tetraspores liberated from the carposporic germlings grew into filamentous thalli. The tissues seperated from the surface layer of the gametophytes, erect Nemalion thalli, regenerated filaments similar to the tetrasporic germlings. When the filaments of tetrasporic germlings and gametophytic tissues were cut into small pieces with razors, they regenerated shoots and grew into new filamentous thalli. By means of cutting treatment, the filamentous thalli propagated in culture. Before cultivation, the filaments were allowed to attach on nori-nets as seedlings according to the following procedures: the filaments propagated in culture were cut into small pieces, and the pieces were scattered on the netting twines immersed in culture vessels fullfiled with culture media, and kept aeration with air compressor for 2 to 3 months. After transfer into the sea in winter, the pieces of the filamentous thalli on the netting twines gave rise to erect thalli in a week, and grew to adult cylindrical Nemalion thalli of 10 to 15cm length after 4 to 5 months.
