It is practically impossible to propagate orchid species
by seed in horticultural substrates. This was a bottle-neck in
orchid industry until the discovey of germination of orchid seeds in
sterilized nutrient media in vitro (since Knudson in '20es). In Nature
germination of orchids is scanty and due to the contact of seeds with particular
symbiotic fungi.
In vitro germination is performed in specialised nurseries and
is used for natural species and in order to obtain hybrids. For many hybrids
since 1960 in vitro cloning (micropropagation, which is similar to the obtention
of micro cuttings) has been used, so millions of identical plants may be
obtained.
