|Title:||Reproductive Biology of Aglaomorpha meyeniana (Polypodiaceae; Pteridophyta)|
Department of Life Science, NTNU
Aglaomorpha meyeniana is an epiphytic fern native to Taiwan. It has been classified as a vulnerable species because of its rarity. This study focused on its reproductive biology and evaluated the practicality of situ sexual propagation. Sporophyll matured and released spores from May to September. Fresh spores began to germinate within 5 days. Germination rate reached 96% after 3 weeks culture. Development of gametophytes included both "Vittaria" and "Drynaria" types. Mature gametophytes were heart-shaped. Antheridia were produced after 6 weeks culture. Archegonia were not produced until after 8 weeks culture. Young sporophytes were produced by 12 weeks culture after fertilization. All sporophytes survived after 6 months culture. The culture of spores should be an effective method of reproduction and lessen the pressure of human collection.
