    • A method and apparatus is disclosed for growing embryonic or other undeveloped plant material in a controlled, biologically sterile environment to produce plants capable of surviving in soil in an uncontrolled environment. Cloned somatic embryos of a particular plant are individually embeddeed in separate sterile plugs comprised of a soil-like particulate medium. A volume of aqueous medium comprising a source of carbon and energy for the somatic embryos, and plant growth regulating substances, if required, is added to each plug. The sterile 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. While in such isolation, the resulting plantlets develop roots and shoots. The resulting autotrophic plants are then removed from isolation and the growth medium is altered to remove the carbon and energy source to limit the capacity of the medium to support plant harming microbes. The plants are then transplanted. Several embodiments are disclosed involving compartmentalized trays and covering films or bags by which embryo-containing plugs are kept isolated from each other and from the environment during development of the embryos.
    • 公开了用于在受控的生物无菌环境中生长胚胎或其他未开发的植物材料以产生能够在不受控制的环境中在土壤中存活的植物的方法和装置。 将特定植物的克隆的体细胞胚分别嵌入由包含土壤样颗粒介质的单独的无菌塞子中。 如果需要,将一定体积的含有体细胞胚的碳源和能量的水性介质和植物生长调节物质加入到每个塞子中。 然后将无菌塞从环境环境中分离,同时允许暴露于足以在插塞中发育的胚胎中发展光合作用的光和大气。 在这种隔离下,所产生的小植株发育出根和芽。 然后从分离中除去所得的自养植物,改变生长培养基以除去碳和能源,以限制培养基支持植物伤害微生物的能力。 然后移植植物。 公开了几个实施例,其涉及分隔的托盘和覆盖膜或袋,通过该薄膜或袋,含有胚胎的塞子在胚胎发育期间彼此隔离并且与环境保持隔离。
