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%.
