| Abstract: | The germination of seeds of 10 species of Cymbidium (native of Yunnan Province) was studied. The 10 species include cpiphytic, semi-epiphytic and terrestrial species. The sceds of epiphytic and semi-epiphytic species are easy to germinate and sensitive to hormone treatment. The combination of NAA and BA promotes the bud formation of the protocorms. Whereas the seeds of terrestrial species are difficult to germinate and must be treated first with some chemicals, such as 0.1 N NaOH or 1.5% H,O, or cut with a pair of scissors. Under the influence of hormone and seed treatment, the percentage of seed germination of certain terrcstrial species amounts to 40%. |
