摘要

扇形文心蘭在植物分類上屬文心蘭亞族的迷你型原生種附生蘭，於原生地可週年開花。本研究以扇形文心蘭為親本，與文心蘭亞族7屬9種進行雜交試驗。共計6個雜交組合可著果，以扇形文心蘭為母本，有3個雜交組合著果，以扇形文心蘭為父本也有3個雜交組合著果。扇形文心蘭與劍葉文心蘭屬三個栽培種及紅茹氏蘭雜交產生的種子可發芽。每個雜交果實產生子數目從1至數十株不等。顯示扇形文心蘭與文心蘭亞族的異屬成員雖具有雜交親合性，但仍存在雜交障礙，幼苗生成數偏低。

Erycina pusilla is a twig epiphyte belonged to a member of Oncidiinae, flowering around the year in its native habitation. This species has short juvenility which is under one year. But this species had seldom used in oncidium breeding in the past breeding program. This study was mainly about Ery. pusilla and hybridization with 9 species or cultivars of 7 genera in Oncidiinae. The fruit set of three crosses were produced when Ery. pusilla as the seed parent or when it as the pollen parent, respectively. Rod. lanceolata and three cultivars among genus Tolumnia produced off springs when crossing with Ery. pusilla. The number of hybrid seedlings produced from per capsule was one to dozens. This result indicated that there was compatibility between Ery. pusilla and other genus in Oncidiinae, but hybridization barriers did exist, only few hybrid seedlings were produced from one capsule.
