Abstract
Liberated tetraspores from Catenella nipae Zanardini ((Rhodophyta, Gigartinales) collected from Kyaikkhami (Lat. 16° 05′ N, Long. 97 ° 34' E) and Setse (Lat. 15° 52′ N, Long. 97 ° 38′ E) coastal areas had been cultured under the laboratory conditions to investigate the germination pattern of this species based on the early stages of cell divisions and development of tetraspores in culture. In the tetraspores germination of C. nipae, primary rhizoid developed from lower cell after second cell division during 2 days in culture. After 5 - 10 days, tetraspore germlings continued cell divisions from 5 to 18 cells and the rhizoid cells divided into 2 - 4 cells reaching a length of 10 - 150 μm. The 15 days old germlings were observed with several cell divisions and produced another rhizoid. The initial of erect blade was observed when the lengths of rhizoids were 800 μm during the experimental period of 1 month. In addition, effects of salinity and medium on spore germination were briefly discussed.
