抄録: Eckloniopsis radicosa (KJELLM.) OKAMURA, a species of Laminariles, is distributed along middle and southern Pacific coasts of Japan and it is affined to species of Eisenia and Ecklonia. The life history of this alga was studied by laboratory and field cultures. The intergeneric hybridization between this alga and other species of Eisenia and Ecklonia were also experimented. E. radicosa collected at Ushibuka, south-western Kyushu, liberated many zoospores from the middle of July to early of September. Settled zoospores issued a germ-tube and developed into branched filamentous male and female gametophytes. Morphological forms and developmental patterns of gametophytes and young sporophytes were almost similar to those of other species of Laminariaceae described by previous investigators. When the sporophytes attained about 2-4cm long or more, white stripes appeared on the lamina, and they were consisted of numerous mucilage glands. This plant also had mucilage canals which showed networked patterns. After 3 months culture in the sea, they grew up to ovate lamina with undulate margins. From the cytological observation, chromosome number of this alga was ca. 60 in the diploid phase, and ca. 30 in the haploid phase. Hybridization experiments proved a complete interfertility between E. radicosa and Ecklonia cava, and between E. radicosa and Ecklonia kurome.
