Abstract

Sasa borealis Makino is distributed in East Asia such as Korea, Fushun in China, and Japan. Especially the species is only found in the high altitude (above 600 m) at mountain of cold regions including The Korean Peninsula. The level of genetic diversity and population structure of this species was surveyed using starch gel electrophoresis at putative five enzyme loci from three natural populations in Korea. Results from twelve loci indicated that genetic diversity was low. In addition, analysis of fixation indices revealed a substantial heterozygosity deficiency in some populations and loci. The reasons for the deficit of heterozygosity may be partly considered inbreeding, small population sizes, and mating of demes. S. borealis can reproduce extensively by producing rhizomes and potentially by sexually produced seeds. Rhizomes are generally long, prostate stems rooting at the nodes.

조릿대(S. borealis)는 다년생 초본으로 한국, 일녈, 중국의 일부에 제한적으로 분포한다. 이 종은 자가 및 타가수분에 의한 혼합번식 형태를 취한다. 전분 전기영동을 이용한 12개의 대립 유전자좌위에서 종의 교배계를 조사하였다. 교배계에서 타가 및 자가 수분, 그리고 줄기의 변형으로 영양번식이 이루어지는 매우 복잡한 혼합 방식의 교배 양식은 제한된 분포, 고산식생대 등의 환경에서 생존할 수 있는 조릿대의 생존전략과도 관련이 있을 것으로 보인다 또한 일부 자생지 파괴에 대한 유효집단의 감소가 일어나 생물자원 확보를 위한 자생지 보존이 필요하다
