Patent number: 7168205Abstract: The present invention relates to an improved coating for manufactured seeds wherein the coating is able to resist cracking at temperatures below about 1° C. The coating usable with the present invention is comprised of a wax impregnated cellulose substrate wherein the wax composition is comprised substantially of paraffin hydrocarbon cellulose substrata having a Gaussian distribution of carbon chain length ranging from 21 carbons per chain to 40 carbons per chain and a maximum number of paraffin hydrocarbon chains having 31 carbons per chain. One aspect of the present invention is that it provides a wax formulation able to resist cracking at low temperatures and also a wax formulation with a desirable viscosity for commercial manufactured seed coat applications.Type: GrantFiled: December 5, 2001Date of Patent: January 30, 2007Assignee: Weyerhaeuser Co.Inventors: Jeffrey E.

Patent number: 5732505Abstract: The present invention provides manufactured seeds comprising a unit of a totipotent plant tissue and methods related to their production and use. The totipotent plant tissue is preferably disposed relative to a hydrated gel, preferably an oxygenated hydrated gel, so that liquids can be transfered from the gel to the embryo. It is also preferable that the shoot of the germinating embryo is enclosed in a shoot restraint that is resistant to penetration by the growing shoot and that the totipotent plant tissue, together with the gel and/or restraint, be at least partially surrounded by a protective seed coat. The manufactured seed can be stored for long periods of time after dehydration and/or freezing.Type: GrantFiled: June 7, 1995Date of Patent: March 31, 1998Assignee: Weyerhauser CompanyInventors: William C. Carlson, Jeffrey E. Hartle

Patent number: 5701699Abstract: The present invention provides manufactured seeds and related compositions and methods. The manufactured seeds comprise a unit of a totipotent plant tissue, preferably in contact with a hydrated gel. Preferably, the shoot of the germinating embryo is enclosed in a shoot restraint that is resistant to penetration by the growing shoot. The manufactured seed may be at least partially surrounded by a protective manufactured seed coat. The gel or the seed coat can include various additives, such as nutrients, antibiotics, or plant growth regulators.Type: GrantFiled: June 7, 1995Date of Patent: December 30, 1997Assignee: Weyerhaeuser CompanyInventors: William C.

Patent number: 5687504Abstract: 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.Type: GrantFiled: March 31, 1995Date of Patent: November 18, 1997Assignee: Weyerhaeuser CompanyInventors: William C. Carlson, Jeffrey E. Hartle, Barbara K. Bower

Patent number: 5666762Abstract: The present invention provides manufactured seeds comprising totipotent plant tissue and a hydrated gel, preferably surrounded by a protective seed coat. The cotyledons of the germinating totipotent plant tissue can be enclosed in a shoot restraint that is resistant to penetration by the growing cotyledons. The manufactured seeds can be prepared for long-term storage, e.g., by sparging the hydrated gel with a respiration-limiting gas before, during, or after assembly of the manufactured seed. The seed is then preferably stored in an atmosphere containing levels of a respiration-limiting gas sufficient to keep respiration of the totipotent plant tissue at reduced levels.Type: GrantFiled: June 7, 1995Date of Patent: September 16, 1997Assignee: Weyerhaeuser CompanyInventors: William C. Carlson, Michael K. McKinnis, Jeffrey E. Hartle
