Abstract

The number and abundance of epiphytic algae growing on Sargassum thunbergii and their functional forms were examined. Thalli of S. thunbenii were collected on the nine islands of southern coast and at Gyeokpo on the western coast of Korea in summer 2001. A total of 25 species, 6 green (24%), 2 brown (8%), 17 red algae (68%) were identified in the present study. Caulacanthus okamurae, Ulva pertusa, Sphacelaria furcigera were found on the thalli of S. thunbegii that collected at the all regions. Caulacanthus okamurae, Champia bifida and Laurencia venusta grew on the lower parts of S. thunbergii thalli whereas, Polysiphonia spp. attached to the apical parts of the plants. Four functional forms, such as sheet-form (8%), filamentous-form (52%), coarsely branched-form (32%) and articulated-calcareous algal form (8%) were distinguished. The epiphytic algae on the thalli of S. thunbergii are mainly annual opportunistic algae, filamentous-form algae and smaller red algae. Also, most epiphytic seaweeds of S. thunbergii produce and release spores before pseudoperennial host plants are necrotic in late autumn.

갈조류 지충이의 표면에 부착하는 착생해조류의 종수, 풍부도, 부착위치 및 기능형을 조사하기 위하여 남해안 9개 무인도와 서해안의 격포 해안에서 2001년 여름에 지충이를 채취하였다. 지충이에 착생하는 해조류는 총 25종이 동정되었는데, 분류군 별로는 녹조류 6종(24%), 갈조류 2종(8%), 홍조류 17종(68%) 이었고 남해군의 장고섬, 노루섬, 소목과도에서 생육하는 지충이에 가장 많은 9종이 착생하였다. 착생 해조류 중에서 애기가시덤불, 구멍갈파래, 가위갯쇠털의 순으로 출현 빈도가 높았으며 애기가시덤불은 모든 해안에서 발견되었다. 또한 애기가시덤불, 두갈래사슬풀, 애기서실은 지충이 엽체의 하부에, 붉은실류는 상부에 부착하여 생육하였다. 기능형으로는 막상형 8%, 사상형 52%, 성긴분지형 32%, 유절석회조형 8%가 존재하였으며 각상형과 혁질형 해조류는 없었다. 위다년생인 지충이의 착생해조류는 봄과 여름에 관찰되는 바위두룩과 같은 종이나 사상형의 일년생 해조류가 주로 나타났으며, 유성생식을 하는 이들은 포자생성 및 방출을 숙주 해조류인 지충이의 엽체가 탈락되는 늦가을 이전에 일어난다.
