Abstract

Zostera caespitosa Miki has been identified to be distributed along the seacoasts of Korea and Japan. This study was intended to clarify the morphological characters and the habitat characteristics of Korean Z. caespitosa. It was confirmed that Z. caespitosa is distributed along the seacoasts of South, Yellow and East Seas of South Korea. The habitats were located in the bay and port with the depth varying from 2.5 to 5.2 m. The habitats of Z. caespitosa were rather deeper than that of mixed bed with Z. marina. The sediment in the habitats was composed of well-sorted fine sand or muddy sand. Z. caespitosa showed marked differences in several morphological characters among sites. Morphology of Z. caespitosa varied with water depths, grain size and organic contents of sediments. Flowering shoots occurred by water temperature of 6.0∼13.7℃ from January to early April.

한국산 거머리말속(Zostera, Zosteraceae) 중 포기거머리말(Zostera caespitosa Miki)의 생태 및 분류학적 특성을 파악하기 위하여 생육 환경과 형태적인 특징을 분석하였다. 한반도에 자생하는 포기거머리말읜 생물지리학적인 분포는 동해연안의 덕산항과 대변, 황해 연안의 백령도 두무진과 남해 연안의 진해에서 종의 실체가 확인되었다. 포기거머리말의 생육지는 만과 항구로 수심 2.5∼5.2 m의 사질과 사니질의 퇴적환경에서 생육하였다. 본 종은 같은 생육지에 생육하는 거머리말 군집보다 깊은 수심에서 군집을 형성하였다. 외부 형태적인 특징은 황해 연안의 개체가 동해 연안의 개체보다 크게 신장하였으며, 생식지가 출현한 시기 의 수온은 6.0∼13.7℃로 1월부터 4월초까지 개화하였다. 포기거머리말의 생육지의 수심, 퇴적물의 평균입도와 유기물함량은 개체의 형태적인 형질 변이에 영향을 미치는 것으로 나타났다.
