- The black orchid (Coelogyne pandurata Lindl.) is an epiphytic orchid spesies that iscurrently endangered. To protect and maintain the genetic resources it is necessary to find theproper way to store seeds in a long time. The purpose this study is to determine the viability ofthe black orchid seeds sowed in organic medium with different storage period. The result showedthat the seeds sown in fresh condition has the highest percentage of growth up to 60%, seedswith storage period of 2 weeks has growth percentage of 20%, while the storage period of 4weeks has growth percentage of 2.5%. The growth phase of sowed seeds in fresh condition andseeds storage in 2 weeks periode is phase 4 (second leaf formed embryo) and seeds storage in 2weeks periode is phase 2 (green embryo). This suggest that the storage condition of black orchidseeds is influence physiology and seed viability.Keywords: Coelogyne pandurata Lindl., seed viability, storage periode
