    Artificial regeneration of forests through planting requires high quantities of quality seeds for growing vigorous seedlings. These seedlings are raised in nurseries, where germination capacity (GC) and speed are the most important germination parameters. Germination performance is enhanced by prescribing species-specific dormancy-breaking treatments to individual seedlots in bare-root and container nurseries. For most conifer species in British Columbia, the dormancy-breaking treatments and germination conditions have been worked out, but fine-tuning and optimization could improve germination capacity and speed of germination. Implications of inter- and intra-species variations in germination behaviour and seed quality and their influence on the development of unintentional directional selection of specific genotypes are discussed. The potential of molecular and genomics approaches to understand the underlying biology of seed germination-related problems is also discussed.
