Integration of Somatic Embryogenesis into Operational Forestry: Comparison of Interior Spruce Emblings and Seedlings during Production of 1+0 Stock

Somatic embryos from 15 different clones representing 4 open-pollinated families were germinated in vitro concomitantly with the germination of genetically related seed in the nursery. Emblings (plants produced via somatic embryogenesis) were transferred to styroblocks five weeks following germination, acclimatized to ex vitro conditions under high humidity and low light and then transferred to the nursery where they were grown alongside control seedlings. Seedlings and emblings were tested under the British Columbia Ministry of Forests operational stock quality testing standards. Both seedlings and emblings reached the desired level of frost hardiness before lifting for frozen storage. Post-storage testing showed seedlings and emblings met or exceeded all morphological stock specifications and had high root growth capacity values.
