This study reports symbiotic orchid seed germination on commonly
used orchid cultivation substrates pre-inoculated with
mycorrhizal fungi. The method efficiently yielded high percentages
of seed germination and well-developed protocorms of S.
plicata. Additionally, the established method has advantage over
in vitro symbiotic seed germination because neither laboratory
facilities nor strict axenic condition is required during the seed
germination step. This symbiotic seed germination method should
be useful for both commercial and conservation purposes. Certainly,
the efficiency of the method should be tested on more orchid
species.
