Abstract

In this study, soil samples were collected from cultivated fields of 1-5 year old Korean ginseng in Geumsan, Korea. Spores of arbuscular mycorrhizal fungi were extracted from soils and identified using morphological characteristics and 18s rDNA sequences of the spores. Total 10 species of AMF were identified: Acaulospora longula, Archaeospora trappei, Glomus caledonium, Glomus etunicatum, Glomus intraradices, Glomus mosseae, Glomus sp., Paraglomus occultum, Paraglomus brasilianum, and Scutellospora heterogama. Relative abundance of spores of A. trappei were increased with increase of cultivation period of the ginseng. However, relative abundance of other species of AMF and Shannon diversity (H') of AMF were significantly decreased with the increase of cultivation periods of the ginseng.

본 연구에서는 인삼(Panax ginseng C. A. Mey.) 재배 토양에서 수지상균근균(AMF)의 포자를 분리하여 동정하고 재배기간 별 AMF 다양성을 확인하였다. 충남 금산지역의 재배 기간 1~5년의 인삼 재배지에서 토양을 채집하였다. 인삼 재배지에 분포하는 AMF의 포자를 분리하여 형태 및 분자생물학적 동정을 한 결과, Acaulospora longula, Archaeospora trappei, Glomus caledonium, Glomus etunicatum, Glomus intraradices, Glomus mosseae, Glomus sp., Paraglomus occultum, Paraglomus brasilianum Scutellospora heterogama 등 총 5속 10종이 동정되었다. 연구 결과 재배기간이 오래 될수록 토양 내에 분포하는 수지상균근균의 종 다양성지수와 균등도는 유의미한 차이를 보이며 감소하였다. 그러나 A. trappei 는 재배 기간이 오래될수록 상대수도가 증가하였다.
