<p>Methods and apparatuses are disclosed for growing embryonic or other undeveloped plant material into autotrophic plants. Somatic or zygotic embryos are individually embedded in sterile plugs comprised of a soil-like particulate medium. A volume of aqueous nutritive medium is added to each plug. The plugs are then isolated from the ambient environment while permitting exposure to light and atmospheric gases sufficient to effect development of photosynthesis in the developing embryos in the plugs. The resulting autotrophic plants are then removed from isolation. Subsequent watering of the growth medium removes the carbon and energy source, thereby inhibiting growth of contaminating microorganisms. The plants are then transplanted. Embodiments include compartmentalized trays and covering films by which embryo-containing plugs are kept isolated from each other and from the environment during development of the embryos.</p> |
