Seeds of Rhynchostylis retusa (L.) Bl. germinate faster on the KC medium than on the VW medium. Protocorms of R. retusa were successfully encapsulated in the KC solution (containing 3% sodium alginate) to get synthetic seeds and germination rate of synthetic seeds stored at 4℃ was higher than at 20℃ and 25℃ on the KC medium containing 15% coconut milk, 2 g·L^-1 peptone and 1 mg·L^-1 NAA. Time taken for germination will be longer and germination rate will decrease at different storage temperatures with the increasing of storage time. Survival rates of seedlings from the synthetic seeds stored at 4℃ for 15, 30, 45, 60 and 75 d are 93%, 89%, 80%, 75% and 63% on field transfer, respectively.
