Abstract
This study was carried out to investigate the factors affecting seed germination of Korean native orchids, such as Habenaria radiata, Bletilla striate and Cypripedium macranthum. In general, seeds of H. radiata was effectively germinated on solid medium and the highest germination (29.6%) was achieved on Hyponex solid medium. But shoot growth was better in MS liquid medium containing $100mL\;L^{-1}$ coconut water (MSC medium). Seed germination of B. striata was effectively induced on MS solid medium. However, no seed germination was observed in all liguid medium tested. Seed germination experiments of C. macranthum were performed using 6 kinds of media and seeds harvested 90 days after cross- and self-pollination. Cross-pollinated seeds were germinated on all the media with the best germination ratio of 4.45% on MSC medium. But no germination was observed from self-pollinated seeds.
