Method of preparing a material for an artificial seed
View Patent ↗A method of preparing a material for use in a manufactured seed is provided. The method includes providing the material having a melting temperature. The method also includes subjecting the material to a heat treatment at a temperature about 10% below the melting temperature for a predetermined period of time.
1. A method of making a component of a manufactured seed, comprising the steps of:
(a) providing a biodegradable plastic material that has been heated below the melting temperature of the biodegradable plastic material for a period of time to remove substances toxic to plant embryos;
(b) forming a component of a manufactured seed from the biodegradable plastic material that has been heated according to step (a); and
(c) disposing a plant embryo within the component of the manufactured seed formed according to step (b).
2. The method of claim 1 , further comprising annealing the biodegradable plastic material before forming the component of the manufactured seed.
3. The method of claim 1 , further comprising sterilizing the biodegradable plastic material by submerging the biodegradable plastic material in a mixture of bleach and water for a sterilization soak period of between about 10 minutes and about 40 minutes.
4. The method of claim 3 , wherein the sterilization soak period is about 30 minutes.
5. The method of claim 3 , further comprising the steps of:
(a) rinsing the sterilized biodegradable plastic material; and
(b) drying the rinsed sterilized biodegradable plastic material.
6. The method of claim 1 , wherein the biodegradable plastic material is a polyester material.
7. The method of claim 1 , wherein the biodegradable plastic material is polylactic acid or polycaprolactone.
8. The method of claim 1 , wherein the component of a manufactured seed is a seed shell.
9. The method of claim 1 , further comprising forming a primary end seal from the biodegradable plastic material that has been heated according to step (a).
10. The method of claim 8 , further comprising using the seed shell in the manufacture of a manufactured seed.
11. The method of claim 9 , further comprising using the primary end seal in the manufacture of a manufactured seed.
