Abstract
Conifer somatic embryos can be desiccated to a moisture content below 50%. A moisture content as low as 10% can be produced. The desiccated somatic conifer embryos have greatly increased ability to store lipids and other nutrients as compared to the corresponding zygotic embryo. The embryos are desiccated using a method which requires the utilization of ABA and PEG.
Claims8
A desiccated conifer somatic embryo having a moisture content ranging between 10 and 32%, a dry weight between 30 and 600% higher than the corresponding mean dry weight of a zygotic embryo from a mature seed of the same species, and an amount of storage lipid between 50 and 700% higher than the corresponding mean amount of lipid of a zygotic embryo from a mature seed of the same species, wherein the desiccated conifer somatic embryo is capable of germinating into a viable plant.
A desiccated conifer somatic embryo having a moisture content below about 32%, a dry weight between 30 and 600% higher than the corresponding mean dry weight of a zygotic embryo from a mature seed of the same species, and an amount of storage lipid between 50 and 700% higher than the corresponding mean amount of lipid of a zygotic embryo from a mature seed of the same species, wherein the desiccated conifer somatic embryo is capable of germinating into a viable plant.
A desiccated conifer somatic embryo, said embryo having a moisture content ranging between 32 and 50% and a dry weight and per embryo lipid content which are higher than the mean lipid content and mean dry weight of the corresponding conifer zygotic embryo from a mature seed of the same species, wherein the desiccated conifer somatic embryo is capable of germinating into a viable plant.
