[[alternative]]The Study of Genetic Structure of Sphaeropteris lepifera(Hook.)
, 2010 [[abstract]]筆筒樹是蕨類植物的一種，屬於欏科(Cyatheaceae)。主要分布在 亞洲大陸邊緣的島嶼上如臺灣、琉球、菲律賓。臺灣位居這一個島弧的中 點，這個島上的筆筒樹族群結構自然值得深入研究。本研究旨在檢視臺灣 各地區筆筒樹的亞族群遺傳結構情形。總共檢查十八個亞族群，十三種同 功酵素，包含十六個基因座。各採樣點的平均族群遺傳變異度理論值(HE) 為0.057，範圍介於0.050-0.063之間，實際觀測值(HO)為0.064，範圍介於 0.035-0.082之間，總遺傳變異度(HT)為0.
