Symbiotic?fungus is indispensable to seed budding of orchid?plants. Habitats can affect fungus; therefore, environmental conditions in the seed germination site should be as similar as to the original habitat to keep an ideal seed germination and seedling growth. In this experiment, Dendrobium sinense seeds were germinated in different host barks as epiphytes in the local (the originally-grown site) site and the laboratory. The results were as follows. (1) D. sinense seeds sowed in the local site and laboratory began to germinate at day 75. The germination rate of D. sinense protocorms grown as epiphytes on host barks peaked at day 135 and the germination rate of protocorms from D.sinense seeds tended to be stabilized 185 days after seeding; (2) Under the laboratory condition, parts of green protocorms started disappearing at day 150; (3) A small amount of D.sinense seeds planted on Syzygium buxifolium germinated under the local and laboratory conditions. There was no germination of the seed grown on Exbucklandiatonkinensi and Pinus massoniana. D. sinense seeds on Cyclobalanopsis blake germinated only under the laboratory condition, whereas D. sinense seeds on Podocarpus neriifoliu geminated only under the local condition, indicating that germination of D. sinense protocorms was influenced by the environment conditions in the seeding site.
