UJI VIABILITAS BENIH ANGGREK HITAM (Coelogyne pandurata Lindl.) DENGAN MASA SIMPAN YANG BERBEDA

Abstract

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