Abstract

Experimental transplantation of Eklonia stoionifera to natural rock was carried out using adhesive Blue. A plant was attached to an architecture tile ($10\times$10 cm) with the glue, and then the tile was attached to natural rock with underwater glue. Within one month, the tile were fixed to natural rock with an attachment rate of $75\%$, and 5. stoionifera grew up with an insertion rate of $66.7\%$ on the tile. After two months, number of E. stolonifera on the tile decreased. However, the attached plants were regenerated by new stolons, maintaining good growing condition. After seven months,5. stoloaifera increased 6 to 71 individuals. These results indicate that regeneration of plants was mainly affected by the recruitment of stolen around the plant.

순간접착제를 이용하여 곰피를 인공 기질에 부착시킨 후, 수중에 이식하여 인공 해중림 조성의 방안을 마련하기 위한 연구를 실시하였다. 계절별로 채집 동정된 해조류는 녹조류 8종 ($16.7\%$), 갈조류 12종 ($25.0\%$) 및 홍조류 28종 ($58.3\%$)으로 총 48종이었다. 곰피는 2000년 11월 순간접착제로 건축용 타일 ($10\times$10cm)에 부착시킨 후, 이 타일을 수중 자연암반에 고정시켜 이식실험을 실시하였다. 이식 1개월 후 타일은 성공적으로 암반에 고정되어 $75.0\%%의 부착율을 보였다. 타일에는 $66.7\%$의 높은 착생율로 22개체의 곰피가 착생하여 생장하였다. 2개월 후, 타일에 착생한 곰피는 유실된 개체로 인해 6개체가 기질에 착생하여 생장하였지만, 착생초기에 비해 새로운 포복지가 많이 재생되었으며 엽체의 생육상태도 좋았다. 이식 7개월 후인 2001년 8월, 6개체였던 곰피는 포복지가 재생되어 총 71개체로 증가하였다. 곰피는 초기 이식한 개체수가 파도에 의한 유실이나 섭식에 의한 탈락이 많았지만, 건강하게 자란 개체들의 활발한 포복지 재생에 의해서 많은 개체수로 증가하였다. 이는 낮은 착생율을 보일지라도 건강하게 자란 엽체가 있을 경우, 이들 개체로부터 많은 재생이 일어날 수 있음을 시사하였다.
