Orchid Flasking Growing Orchids by John Marvin Orchid flasking is a procedure in which orchids can be grown from seeds, and is necessary for producing orchid seedlings, since orchid seeds do not have an endosperm and usually require a symbiotic mycorrhizal fungus to germinate. There are two different techniques for flasking: symbiotic germination and asymbiotic germination. Symbiotic germination requires the isolation of a mycorrhizal fungus which is added to the agar in which the seeds are grown. Asymbiotic germination just uses the nutrients that the seed requires to grow.
