|Other Titles:||The Effect of Storage Conditions on the Spore Viability of Aglaomorpha Meyeniana Schott. (Polypodiaceae, Pteridophyta)|
Department of Life Science, NTNU
Aglaomorpha meyeniana Schott. is a rare fern in Taiwan. It could be propagated by artificial sexual reproduction for conservation ex situ. However, this successful reproduction is related to its spore viability, which is greatly affected by the storage condition. In this study, 6 conditions, i. e., -80 ~ -74℃, -30 ~ -20℃, 0 ~ 6℃, and 21 ~ 29℃ of dry surrounding, and 0 ~ 6℃ and 21 ~ 29℃ of water immersed, were used to store spores of Aglaomorpha meyeniana. The viability of those stored spores was detected by their germination rates every month. Results showed that germination rates were 92%, 85%, and 6% for spores stored under -80 ~ -74℃ dry condition, 21 ~ 29℃ water immersed condition, and 21 ~ 29℃ dry condition, respectively, after 10 months storage. However, 30% stored spores germinated when they were immersed in water at 21 ~ 29℃. Almost all spores which were stored under other three conditions lost their viability.
