The present invention provides manufactured seeds comprising a plant embryo or other unit of totipotent plant tissue. The totipotent plant tissue is preferably protected from mechanical damage, desiccation, and attack by pathogens, pests, etc. by a manufactured seed coat. In a preferred embodiment, at least a portion of the seed coat is impenetrable by plant tissue germinating within it, but a second portion is penetrable. Preferably, the penetrable second portion is an opening in the seed coat across which can be disposed an end seal.

The following example is based on the manufactured seed design comprising an embryo, seed coat, and hydrated gel as shown in FIG. 7 of U.S. Pat. No. 5,427,593. As the term is used below, a "seed coat plus gel" refers to a manufactured seed lacking the embryo and an end seal.
Zygotic embryos of Douglas fir are placed in a shoot restraint, then dehydrated by placement in an open dish over a saturated CaNO3 solution in a closed vessel for one week. The resulting dehydrated embryos (in shoot restraints) are then frozen by placement in a -17� C. freezer.
Before inserting the desiccated and frozen embryo in the seed coat plus gel, the seed coat plus gel is frozen by placement on a block of dry ice. After inserting the seed shoot restraint plus frozen embryo in the seed coat plus gel, the resulting assembly is sealed by placing an end seal, e.g., Parafilm� or wax-impregnated, cellulosic tissue, across the opening in the seed coat, then sealing the opening by heating or pressure applied to the end seal, respectively, to complete assembly. After assembly, the manufactured seed are transferred to a freezer at -17� C. (0� F.) for one-month storage.
