阿里山地區玉山杜鵑（森氏杜鵑）根菌結合體形態及其內生菌
Morphology and Endophytes of Root-Fungus Association of ＂Rhododendron pseudochrysanthum (R. morii)＂ in Alishan Area
摘要
本研究主要在探討嘉義縣阿里山鄉阿里山森林遊樂區內的玉山杜鵑之根菌結合體特性。經試驗結果得知，在光學顯微鏡下觀察，其外觀型態為膨大短棒狀；以掃描式電子顯微鏡觀察，於根菌結合體表面可發現有稀疏菌絲覆蓋，在皮層細胞中可發現菌絲圈之顯微構造。另在內生菌部分，共計誘導分離出5株內生菌，經分子生物鑑定，Rm7與Rm28菌株應屬於不完全菌Phialocephala屬；Rm9菌株應屬於子囊菌Hyaloscyphaceae科；Rm15菌株應屬於子囊菌Rhizoscyphus屬；Rm42菌株應屬於不完全菌Cryptosporiopsis屬。綜合以上研究結果得知，阿里山地區玉山杜鵑之根菌結合體是屬於杜鵑類菌根。
並列摘要
This study is an investigation of the root-fungus association characteristics of ＂Rhododendron pseudochrysanthum＂ in Alishan area. Light microscopy found the association swollen, short and stout. Under electron microscope scan, the ultrastructure showed the hyphae sparsely attached to the surface of association and the hyphal coil in its cortical cells. Molecular analysis of five strains isolated from samples demonstrated that strains Rm7 and Rm28 belong to the genus ＂Phialocephala＂, Rm9 to Hyaloscyphaceae, Rm15 to ＂Rhizoscyphus＂, and Rm42 to ＂Cryptosporiopsis＂. These results indicate that the root-fungus association of ＂R. pseudochrysanthum＂ from the Alishan area belongs to the ericoid mycorrhiza.
