Abstract

This study was conducted to investigate the effect of thinning on ectomycorrhizal fungal communities in a forest. Ectomycorrhizal root tips were collected from forest soils in thinning and non-thinning sites and identified using morphological characteristics and molecular analysis of ITS rDNA sequences. As a result, species richness of ectomycorrhizal fungi was significantly increased and ectomycorrhizal fungal community composition was changed by thinning. These results suggest that forest management such as thinning, could be an important factor affecting mutualistic relationships and belowground microorganisms in forest ecosystems.

본 연구에서는 간벌 처리에 따른 외생균근균의 군집 구조의 변화를 확인하기 위해 간벌지와 비간벌지에서 정량적으로 토양을 채취하여 간벌에 따른 외생균근균의 종 다양성, 종 수, 외생균근 수, 군집 내 종 구성을 비교하였다. 분석 결과 간벌지와 비간벌지는 공통적으로 Russula 속이 우점하고 있으나, 간벌 처리 후 산림 토양의 외생균근균 군집의 종 구성이 달라지고 종 수가 증가되는 것을 확인하였다. 본 연구결과는 간벌이 산림 생태계의 지상부 뿐만 아니라 외생균근균과 같은 토양속의 미생물의 군집 구조에도 유의미한 영향을 미치는 중요한 요인이라는 것을 보여주고 있다.
