초록
최근 양식기법이 보급되어 어가의 양식이 활발해진 감태 (Ecklonia cava Kjellman)는 향후 다양한 품종개발이 예상되고, 이들의 구분을 위한 신품종 심사기준 (특성조사요령) 작성과 기초자료가 되는 자연 개체군의 변이 폭과 지역적 형태 변이에 관한 연구 필요성은 더욱 커지고 있다. 본 연구는 감태 양식 개체군과 국내 연안 16개소에서 채집한 자연개체군의 형태를 비교하고, 주요 형태 형질의 특성과 변이 폭을 규명하고자 하였다. 감태의 품종 구분에 적합한 형질은 1차엽과 2차엽, 줄기에 대한 주요 형태와 특징에 관한 14개 측정 형질과 4개 비율 형질, 총 18개 특성을 선정하였다. 군집 분석에서 전체 19개 개체군 중, 자연개체군인 장길 (E4), 소록 (S7)은 동일 지역 개체군들과 유의한 차이를 보였고, 동해와 남해의 나머지 자연 개체군은 양식 2년생인 수유 (Q6, Q8, Q10)를 포함한 2개 집단으로 구분되었고, 제주의 3개 개체군은 별도의 집단을 이루어 지역적으로 구분되었다. 주성분 분석에서도 군집 분석에서 집단을 이룬 동해와 남해 개체군을 중심으로 양식 개체군은 중앙에 모여 나타났고, 장길 (E4), 소록 (S7)과 제주 개체군들은 주성분 1 (PC1)과 주성분 2 (PC2)에 연관된 2차엽 지수, 줄기의 길이와 직경, 줄기 길이/1차엽 길이, 1차엽 길이와 너비, 2차엽 수, 2차엽 길이와 너비의 형질에 의해 각 축에 따라 구분되어 나타났다. 이상의 결과로 본 연구에서 조사한 18개 형질은 각 해역에서 유의한 차이를 보이는 개체군 구분을 위한 기준으로 유용성이 확인되었으며, 감태의 각 지역 개체군은 향후 신품종 개발 후보 종으로 가능성이 클 것으로 기대되었다.
Abstract
Ecklonia cava Kjellman, which has recently gained popularity due to the spread of farming techniques, is expected to be developed in various varieties in the future. There exist increased needs for research on the basis of natural populations and inter-regional morphological variations. We compared the morphology of the aquaculture and natural populations from 16 coastal areas in Korea. The 18 traits found suitable for distinguishing varieties were selected from 14 measurement traits and 4 ratios related to the main morphology and characteristics of primary blade, secondary blade, and stipe. In the cluster analysis, Janggil (E4) and Sorok (S7) showed significant differences from those of the same coastal region. Two groups, including Suyou (Q6, Q8, and Q10) which was the second year of farming, of the rest of the populations from East sea and southern coast were distinguished. Three populations of Jeju were divided into a regional group. In the principal component analysis (PCA), a large number of populations from East sea and Southern coast appeared in the center with aquaculture populations. PC1 and PC2 associated with traits of secondary blade index, stipe length and diameter, stipe length/primary blade length, primary blade length and width, secondary blade number, secondary blade length and width, divided E4, S7 and populations of Jeju region. As a result, the 18 characters of this study were found to be useful as criteria for discrimination of populations with significant differences in each coastal region, and these populations were expected to be candidates for new varieties.
