In one aspect, the present invention provides methods of storing conifer
somatic embryo germinants germinated on a sterile germination medium for
delayed transplanting into a growth medium. The methods of the invention
comprise the steps of: (a) placing the germinants while still on sterile
germination medium into a cold environment in which the temperature is in
the range of 0.5.degree. C. to 10.degree. C. for a time period up to six
months, said germinants comprising a visible, well-defined epicotyl and
radicle; and (b) placing the germinants in water for a time greater than
about 1 hour at a temperature below about 24.degree. C. prior to
transplantation into growth medium.
