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.   

Key words: Plurispores, Cladosiphon okamuranus, Multiaxial, Hair, Pseudoparenchyma
