Abstract

This study was conducted to identify the morphological characteristics and variations level by site environment of native bermudagrass (Cynodon spp.) from costal and island region in South Korea. Soil chemical properties and morphological characteristics were investigated. There were significant differences in plant height, leaf width, leaf length, cotton on leaf blade, stolon, and number of seed per spike depending on where they were collected from natural habitat. We have discovered a variety of variation among the investigated traits in Korean native bermudagrass ecotypes. There were broad leaf and fine leaf types of native bermudgarass in S. Korea. Adaptability was in very high on inadequate environment in bermudagrass with broad leaf types, it has also been suggested that management worth in terms of use. These results may provide basic information for bermudagrass breeding development and the collected types during this investigation would be worth being preserved as genetic resources for further breeding purposes.

본 연구는 국내 해안 및 도서지역에 자생하고 있는 버뮤다그래스를 지역별로 수집하여 입지환경에 따른 형태적 변이 정도를 알아보고자 수행되었다. 이들 입지환경, 토양의 화학성과 형태적 특성을 조사하였다. 수집된 자생지에 따라 초장, 엽폭, 엽장, 잎털, 포복경 및 화수당 종자수 등에서 큰 변이를 보여 조사 형질 간에 다양한 변이를 보이는 것을 확인할 수 있었다. 광엽과 세엽 특성의 버뮤다그래스가 존재하고 있었으며, 광엽형의 버뮤다그래스의 경우 열악한 환경에서의 적응성이 매우 높아 중 저관리의 잔디면에 이용 가치가 높을 것으로 생각된다. 상기 입지 환경과 형태적 특성 조사 결과 및 수집된 유전자원들은 앞으로 유전자원으로서 보존 가치가 높으며, 유용유전자를 보존할 수 있는 체계가 마련되어야 할 것으로 판단된다.
