Seed conservation and In Vitro Regeneration of Philippine Indigenous Orchids
This is a technique to conserve the biodiversity of Philippine indigenous orchids using their seeds. Materials are conserved under controlled environment and regenerated via tissue culture. This method complements other existing conservation efforts, which involve maintenance of live plants. In vitro germination of conserved seeds shows germination decreases with time, although germination of greater than 80% can still be obtained after one year of storage for species such as Dendrobium heterocarpum and Grammatophyllum scriptum. Different species respond differently to low temperatures and low moisture storage and consequently to in vitro germination. The conservation technique is applicable to specific species of Philippine indigenous orchids.
