Shoot restraint for use with manufactured seeds
The present disclosure includes a shoot restraint for use with manufactured seeds comprising. In some embodiments, the shoot restraint includes a substantially porous material having a top surface and a bottom surface. The substantially porous material is formed to define a substantially cylindrical upper portion having an upper diameter; and a substantially cylindrical lower portion having a lower diameter. The upper diameter is larger than the lower diameter. A parabolic cavity extends from the top surface to the bottom surface through the upper portion and at least partially into the lower portion.
1. A shoot restraint for use with manufactured seeds comprising:
a substantially porous material having a top surface and a bottom surface, the substantially porous material being formed to define:
a substantially cylindrical upper portion having an upper diameter; and
a substantially cylindrical lower portion having a lower diameter, the upper diameter being larger than the lower diameter; and
a parabolic cavity extending from the top surface to the bottom surface through the upper portion and at least partially into the lower portion.
2. The shoot restraint of claim 1 wherein the upper portion has an upper depth and the lower portion has a lower depth, the lower depth being larger than the upper depth.
3. The shoot restraint of claim 1 wherein the bottom surface is chamfered.
4. The shoot restraint of claim 1 wherein the bottom surface is rounded.
5. The shoot restraint of claim 1 wherein upper diameter is approximately 0.20 inches to approximately 0.35 inches and the lower diameter is approximately 0.10 inches to 0.15 inches.
6. The shoot restraint of claim 5 wherein the parabolic cavity has a cavity depth, the cavity depth being approximately 0.10 inches to approximately 0.22 inches.
7. The shoot restraint of claim 1 wherein upper diameter is approximately 0.15 inches to approximately 0.24 inches and the lower diameter is approximately 0.10 inches to 0.18 inches.
8. The shoot restraint of claim 7 wherein the parabolic cavity has a cavity depth, the cavity depth being approximately 0.10 inches to approximately 0.20 inches.
9. The shoot restraint of claim 1 wherein the upper portion further comprises:
a first chamfered portion; and
a second chamfered portion.
10. The shoot restraint of claim 1 wherein the substantially porous material has a hardness strong enough to resist puncture or fracture by a germinating embryo.
11. The shoot restraint of claim 10 wherein the substantially porous material is a porcelain or a ceramic.
12. A shoot restraint for use with manufactured seeds comprising:
a substantially porous structure having a top surface and a bottom surface, the top surface having a substantially circular cross-sectional area; and
a cavity extending from the top surface to the bottom surface, the cavity having a substantially parabolic cross-sectional area.
13. The shoot restraint of claim 12 wherein:
the top surface of the structure has an upper diameter and the cavity has a cavity diameter, the cavity diameter varying along the cavity's length; and
wherein the upper diameter is approximately the same size of the cavity diameter at its widest point.
14. The shoot restraint of claim 12 wherein the cavity has a cavity depth, the cavity depth being approximately the same size as the cavity diameter.
15. The shoot restraint of claim 12 , further comprising:
a substantially cylindrical upper portion having an upper diameter; and
a substantially cylindrical lower portion having a lower diameter, the upper diameter being larger than the lower diameter.
