Abstract

This study was conducted to investigate the occurrence of weed flora in pastures in Jeju island of Korea and to establish the basic data for controlling them occurred in the pastures. Weed flora was investigated twice, May and July on 2003. There were a total of 207 weed species including 49 families. Among them 67 species were annual, 39 species were biennial and 101 species were perennial. The compositions of major plant families, Asteraceae, Poaceae, Polygonaceae, Rosaceae, Fabaceae were 17, 15, 8, 7, 6%, respectively. Sixty-eight species of exotics were occurred, as well. Rumex obtusifolius was the highest in importance analysis and the followings were in order of Trifolium repens, Artemisia princeps, Plantago asiatica, Potentilla anemonefolia and Rumex acetosella etc. Among the exotic weeds, R. obtusifolius, T. repens, R. acetosella and C. holosteoides var. hallaisanense might be most problematic weeds species in pastures in Jeju island in the future. And at the boundary of some pastures and mountains Smilax china, Duchesnea indica, Rosa maximowicziana, etc. 17 shrub species were also occurred.

제주도 목초지에 발생하는 잡초를 조사하여 목초지 문제 잡초의 현황을 파악하고 잡초방제의 기초자료로 활용하기 위하여 2013년 5월과 7월에 2회 실시하였다. 제주지역 목초지에 발생하는 잡초는 49과 207초종으로 일년생잡초가 전체의 32%를 차지하는 67종, 월년생잡초가 19%로 39종, 그리고 다년생잡초가 49%로 101종이었다. 그리고 과별로 보면, 국화과 17%, 화본과 15%, 마디풀과 8%, 장미과 7%, 콩과 6%, 석죽과, 십자화과, 꿀풀과 각각 3%순으로 발생하였다. 우점도가 높은 잡초로는 돌소리쟁이, 토끼풀, 쑥, 질경이, 가락지나물, 애기수영 등의 순이었다. 외래잡초는 22과 68초종으로 전체 32.9%를 차지하였으며, 이 중에서 돌소리쟁이, 토끼풀, 애기수영, 점나도나물 등은 향후 제주도 목초지에서 문제가 될 것으로 판단된다. 일부 목초지와 산지와의 경계부분에서 청미래덩굴, 뱀딸기, 용가시 등의 목본식물도 발생하였다.
