抄録

In this paper, the morphogenesis of zoospore derived from plurilocular sporangium produced on the thallus of Cladosiphon okamuranus, as well as the influence of water temperature, salinity and illumination on the growth of its germlings were examined in the laboratory.<br>1) The development of most zoospores from plurilocular sporangia showed the discoid type. The discoid germlings derived newly formed plurilocular sporangia and developed into the thalli of sporophyte. However, when the discoid germlings were cultured at a higher temperature (25°C<) or lower illuminance (2.5klx>), there were no growth of the erect germlings; showing only repeated generations of discoid development by the zoospores from their plurilocular sporangia.<br>2) Suitable culture conditions for the attachment of zoospores from plurilocular sporangia in the laboratory were 20-25°C in water temperature, nearly 31‰ in salinity and 1-2.5klx in illuminance.<br>3) As regards the adequate culture conditions for the growth of germlings before reaching 1 mm in height, the water temperature was 25-30°C, but when they began to develop into erect germlings, best growth occurred between 15-20°C, the adequate conditions being 15-45‰ salinity and 5-10klx illuminance.
