제주도 일원 14개소의 감귤원에서 감귤 뿌리를 포함한 토양 시료를 95년 10월에 수집하여 VA균의 포자를 분리하여 관찰 동정하였다. 분리된 공생균근균은 3속 5종으로서 Acaulospora bireticulata, Glomus deserticola, G. geosporum, G. vesiculiferum, Sclerocystis pachycaulis였으며, Acaulospora sp.로 사료되는 두 가지는 아직 종동정이 되지 않았다. 이중에서 G. deserticola와 미동정된 Acaulospora sp.는 모든 시료토양에서 빈도가 매우 높게 관찰되어 우점종으로 사료되었으나, 다른 종에 속하는 포자들은 이들 종에 비하여 관찰 빈도가 매우 낮았다.

Abstract

VA-mycorrhizal spores were collected from the 14 citurs orchards of different soil textures and locations in Cheju island. Five species and two kinds of spores were identified as based on the morphological characteristics of the spores; Acaulospora bireticulata, Glomus deserticola, G. geosporum, G. vesiculiferum, and Sclerocystis pachycaulis. Additionally, two kind spores of Acaulospora were also observed but difficult to be identified in this moment. Glomus deserticola and unidentified spores of Acaulospora (brown spores sized 90 to $125\;{\mu}m$ in diameter) were most frequently observed in the all soil specimens in Cheju, while the other kinds of spores were rarely observed in the soil of Cheju.
