Abstract

In this study, we investigated the spore diversity of arbuscular mycorrhizal fungi (AMF) in rhizospheres of a post-mining area and a natural forest area in Jecheon, Korea. The rhizospheres of the post-mining areas were dominated by Acaulospora mellea, while those of the natural forest area were dominated by Ambispora leptoticha. The number of AMF spores in rhizospheres of the post-mining area was significantly higher than that in the rhizospheres of the natural forest area. Although the diversity index of each area showed no significant difference, the community similarity of AMF within the rhizospheres of natural forest area was significantly higher than that observed within those of post-mining area. These results showed that AM fungal communities in rhizospheres could change because of the degree of disturbance.

충북 제천의 폐광산 지역의 근권 토양과 인근 일반 산림 지역의 근권 토양을 수집하여 토양 내의 수지상균근균(AMF)의 다양성 및 군집 구조를 확인하였다. 폐광산 지역의 근권 토양은 Acaulospora mellea, 일반 산림 지역의 토양은 Ambispora leptoticha가 우점하는 것을 확인하였다. 군집 구조를 분석한 결과, 폐광산 지역의 근권 토양에서 일반 산림 지역의 근권 토양보다 AMF 포자 수가 많은 것을 확인하였고, 두 지역의 종 다양성 지수에는 유의미한 차이가 존재하지 않았으나 일반 산림 토양의 군집 내 유사도 지수가 폐광산 지역의 근권 토양보다 유의미한 수준으로 높게 나타나는 것을 알 수 있었다. 따라서 본 연구는 교란의 차이에 의해 AMF의 군집이 달라질 수 있음을 보여준다.
