Abstract
A desiccation-tolerant mature viable gymnosperm somatic embryo is characterized by a moisture content of less than about 55%. Preferably the moisture content is less than about 45%, and for optimal storage capability at freezing temperatures, less than about 36%. The embryo may have a dry weight and per embryo lipid content higher than the lipid content and dry weight of the corresponding gymnosperm zygotic embryo. Preferred desiccation-tolerant gymnosperm somatic embryos are coniferous somatic embryos having a moisture content of less than about 55%.
Claims33
A desiccated viable mature gymnosperm somatic embryo characterized by having a moisture content lower than the moisture content of its corresponding zygotic embryo and a dry weight and per embryo lipid content higher than the lipid content and dry weight of its corresponding gymnosperm zygotic embryo, said moisture content being less than about 55%.
A desiccated viable mature conifer somatic embryo characterized by having a moisture content lower than the moisture content of its corresponding zygotic embryo and a dry weight and per embryo lipid content higher than the lipid content and dry weight of its corresponding gymnosperm zygotic embryo, said moisture content being less than about 55%.
A viable mature conifer somatic embryo, said embryo having a moisture content ranging between about 32% and about 55% and a dry weight and per embryo lipid content higher than the lipid content and dry weight of its corresponding-conifer zygotic embryo.
A viable desiccated plant embryo encapsulated in a non-hydrated water soluble capsule made of a compound having a melting point ranging between 20° and 70° C., the capsule having been formed by coating a desiccation-tolerant embryo in the compound while the compound is molten and solidifying the compound to form a protective solid coating for the embryo.
A viable desiccation-tolerant gymnosperm somatic embryo having a moisture content below about 55%.
A viable desiccation-tolerant conifer somatic embryo having a moisture content below about 55%.
A viable desiccation-tolerant conifer somatic embryo having a moisture content below about 36%.
A viable desiccation-tolerant conifer somatic embryo having a moisture content ranging between about 55% and about 10%.
A viable desiccation-tolerant conifer somatic embryo having a moisture content ranging between about 36% and about 10%.
