Morphology and Ultrastructure of Root-Fungus Association of Rhododendron formosanum Hemsl. in Sanlinchi Forest of Central Taiwan

中台灣杉林溪森林中台灣杜鵑根菌結合體之形態及微細構造

摘要


本研究探討中台灣杉林溪森林中台灣杜鵑之菌根特徵。台灣杜鵑根系之根菌結合體可區分爲6種形態。其根部組織之微細構造顯示,皮層細胞內有菌絲複合體及菌絲圈之構造。自根系分離純化培養之菌株具有生長緩慢之隔膜菌絲。研究結果證實,杉林溪台灣杜鵑根系之根菌結合體屬於杜鵑類菌根。

This paper describes mycorrhizal character of the Formosan azalea (Rhododendron formosanum Hemsl.), an indigenous ericoid plant in the Sanlinchi forest of Central Taiwan. The root-fungus associations were categorized into 6 morphological types with light microscopy. The root ultrastructure examined with scanning electron microscopy revealed that hyphal complex and hyphal coil structures were present in cortical cells. The isolated fungal strains had slow-growing septate hyphae. The results suggested that the root-fungus association of the Formosan azalea belong to ericoid mycorrhiza.
