1. For the purpose of cultivating Gloiopeltis tenax, which is widely used as a sourse of glue, it was tried to “sow” the spores directy on the rocky shores, taking advantage of their fixing habit, reported in a previous work (Suto 1948).
2. The spores were collected 30 minutes before the flood tide, by immersing the fronds in sea water, which had been collected during low tide. Then the spores were “sown” by sprinkling the spore suspension on the rocky shores just before the flood tide, during late spring.
3. 5-29% of the sown spores fixed themselves on the rocks and gave rise to young buds, in a density of ca. 10/cm2, when examined in the following autumn.
4. This method is hoped to be applicable to the aplanospores of some other algae which also grow in the tidal zone.
