Abstract
A process to assist in germination of spruce somatic embryos. The embryos are desiccated at humidity, preferably in the range of 85 to 99%. A process that differentiates somatic embryos of conifer comprises contacting embryogenic calli with a medium containing abscisic acid. A process for determining the quality of a plant to embryo is also described. That process comprises identifying the storage protein content of the embryo and comparing that content with the storage protein content of mature embryos of the same species.
Claims5
A process for propagation of spruce somatic embryos which includes the steps of differentiating spruce somatic embryos in contact with a growth medium containing abscisic acid, separating the somatic embryos from said medium, and germinating the somatic embryos, characterized in that the embryos are matured on said medium and are partially dried prior to germination by exposing mature embryos separated from the said medium to an atmosphere having from greater than 85% up to 99% humidity.
