영문 초록

Germination efficiency, such as days to germination and conditions for the hybrid seeds, was tested after hybrid seeds were sown on the medium. Seeds were germinated from 67 to 126 days after seeding in all cross combinations, and germination condition was different among hybrid combinations. There was big difference on days to germination based on the different media, that is, days to germination in the hyponex medium was shorter than that in the Knudson C medium. Mutants such as MMS and NaN₃ were used to cause mutation. Germination occurred with 0.1 % NaN₃ and MMS. However, even though germination occurred in other treatments (0.01 % and 0.2% of NaN₃ and MMS), brownish phenomenon was intense, or did not proceed and got worse after 4-5 months of seeding. In addition, it was performed to choose appropriate medium for the growth of Cymbidium rhizome whose media adaptability is more different than other orchids. Different concentration of NAA and Kinetin was used. As a result, C. goeringii hybrid showed difference for the concentration of NAA and Kinetin combination.
