The seed shell is a structure having an open end and a closed end. The restraint comprises a parabolic cavity. A seal assembly is disposed on the open end of the seed shell in a configuration effective to seal the seed shell. ## Claims ### Claim 1 A manufactured seed comprising: a seed shell comprising a structure having an open end and a closed end; a restraint disposed within the seed shell, the restraint comprising a parabolic cavity; and a seal assembly disposed on the open end of the seed shell in a configuration effective to seal the seed shell. ### Claim 2 (depends on 1) The manufactured seed of claim 1, further comprising an embryo disposed within the parabolic cavity. ### Claim 3 (depends on 2) The manufactured seed of claim 2 wherein the embryo is disposed in the parabolic cavity in a substantially perpendicular configuration with respect to a plane in which the sealing assembly is arranged. ### Claim 4 (depends on 3) The manufactured seed of claim 3 wherein the embryo comprises a root end and a shoot end and the embryo is disposed in the parabolic cavity shoot end first. ### Claim 5 (depends on 2) The manufactured seed of claim 2 wherein the embryo is disposed in the parabolic cavity in a substantially parallel configuration with respect to a plane in which the sealing assembly is arranged. ### Claim 6 (depends on 5) The manufactured seed of claim 5 wherein the secondary end seal comprises one or more parabolic dimples. ### Claim 7 (depends on 2) The manufactured seed of claim 2 wherein the embryo is disposed in the parabolic cavity in a substantially skew configuration with respect to a plane in which the sealing assembly is arranged. ### Claim 8 (depends on 7) The manufactured seed of claim 7 wherein the one or more parabolic dimples are coated, at least partially, in a paraffin oil. ### Claim 9 (depends on 2) The manufactured seed of claim 2 wherein the embryo comprises a tree embryo. ### Claim 10 (depends on 2) The manufactured seed of claim 2 wherein the embryo comprises an agricultural crop embryo. ### Claim 11 (depends on 1) The manufactured seed of claim 1 wherein the open end of the seed shell has a seed shell diameter D1 and the restraint further comprises: an upper portion having an upper diameter D2, the seed shell diameter D1 being larger than the upper diameter D2; and a lower portion having a lower diameter D4, the upper diameter D2 being larger than the lower diameter D4. ### Claim 12 (depends on 11) The manufactured seed of claim 11 wherein the parabolic cavity has a cavity diameter D5, the cavity diameter D5 being at least as large as the lower diameter D4. ### Claim 13 (depends on 12) The manufactured seed of claim 12 wherein the upper restraint portion has an upper depth L2, and the parabolic cavity has a cavity depth L5, the cavity depth L2 being substantially larger than the upper depth L5. ### Claim 14 (depends on 13) The manufactured seed of claim 13 wherein the cavity depth L5 is approximately 0.10 inches to approximately 0.20 inches. ### Claim 15 (depends on 13) The manufactured seed of claim 13 wherein the upper depth L2 is approximately 0.15 to approximately 0.30 inches. ### Claim 16 (depends on 13) The manufactured seed of claim 13 wherein the upper depth L2 is approximately 0.20 to approximately 0.30 inches. ### Claim 17 (depends on 11) The manufactured seed of claim 11 wherein the seed shell has a seed shell diameter D1 and the parabolic cavity has a cavity diameter D5, the cavity diameter D5 being substantially the same size as the seed shell diameter D1. ### Claim 18 (depends on 17) The manufactured seed of claim 17 wherein the seed shell diameter D1 is approximately 0.30 inches to approximately 0.40 inches, the upper diameter D2 is approximately 0.20 inches to approximately 0.35 inches, the lower diameter D4 is approximately 0.10 to 0.15 inches, and the cavity diameter D5 is approximately 0.10 inches to approximately 0.30 inches. ### Claim 19 (depends on 17) The manufactured seed of claim 17 wherein the seed shell diameter D1 is approximately 0.20 inches to approximately 0.30 inches, the upper diameter D2 is approximately 0.15 to approximately 0.25 inches, the lower diameter D4 is approximately 0.10 to approximately 0.18 inches and the cavity diameter D5 is approximately 0.10 to approximately 0.20 inches ### Claim 20 (depends on 1) The manufactured seed of claim 1 wherein the seal assembly further comprises a primary end seal and a secondary end seal.
