摘要

臺灣原始觀音座蓮（Archangiopteris somai）因數量稀少及分布地點狹隘成為瀕危物種，本研究於其臺灣的兩處生育地進行根圈土壤叢枝菌根菌調查，以瞭解此瀕危物種之共生菌根菌組成基本資料，經調查於兩處生育地共計發現6屬10種叢枝菌根菌，植株經染根觀察，根內均發現大量菌絲、囊泡與叢枝體，確認臺灣原始觀音座蓮與叢枝菌根菌形成內生菌根。

Archangiopteris somai is an endangered species due to its rare population and distribution in narrow habitats. We investigated the arbuscular mycorrhizal fungi in two habitats of A. somai in Taiwan in order to understand the symbiosis mycorrhizal fungi composition of this endangered species. The results show that 10 AM fungi species of six genera were found in the two habitats. Abundant intraradical hyphae, vesicles and arbuscules were found in root samples, confirming the formation of mycorrhiza of A. somai with AM fungi.
