Abstract:

The minute size of orchid seeds have made them difficult to observe,orchid seeds germination and mortality of seedlings in suit difficult to study.Recently,a new technique was described by which orchid seeds were sowed and retrieved in the field under natural conditions.It is possible to conduct a quantitative study of orchid germination in suit and observe seasonal growth and mortality of seedlings.The technique has also enabled us to bait appropriate fungus from the germinated seeds and young seedlings,which could be beneficial both to the orchid propagation and conservation.For the further studies,the potential issue and application perspective of this technique are also discussed in this text.

Key words: seed of orchid, mycorrhizal fungi, in suit, symbiotic germination
