Abstract:
Development of plurispores and effects of temperature on their attachment to substrata were studied
using mature plurilocular sporangia of Cladosiphon okamuranus Tokida. Development of plurispore showed
the disc type, a large number of assimilatory filaments were found to develop from the middle or central part
of a disc. These compact and parallel assimilatory filaments formed pseudoparenchyma (multiaxial) with
abundant lateral branches. The attachment and development of a plurispore were affected significantly by
temperature. Suitable seeding temperature was found to be 17-26º and 26 being optimum for successful
attachment. At a temperature over 26ºC, the plurispore could not attach tightly to a substratum or developed
poorly.
