Abstract: A manufactured seed is disclosed which comprises a plant embryo preferably encapsulated, or at least in contact with, a hydrated oxygenated gel. The gel can be oxygenated by passing oxygen gas through a gel solution before curing the gel or by exposing the gel to oxygen gas after curing. The gel is preferably oxygenated by adding to an uncured gel solution a suitably stabilized emulsion of a perfluorocarbon compound or a silicone oil, which compounds are capable of absorbing large amounts of oxygen, and are non-toxic and inert. The seed analog can further comprise an outer shell at least partially surrounding the gel and embryo, thereby forming a capsule. The outer shell preferably is shaped to aid the radical of a germinating embryo in protrusively rupturing the capsule, thereby facilitating successful germination and minimizing incidence of seedling malformation. Other shell materials are selected to provide requisite rigidity to the capsule while imparting minimal restriction to successful germination. In a preferred embodiment for germinating embryos having cotyledon(s), at least the cotyledons are enclosed in a porous material resistant to penetration by the growing cotyledon(s), and the embryo and porous enclosure are encapsulated in a hydrated gel.
