Chapter 4: Assuring Seed Quality for Seedling Production- Cone Collection and Seed Processing, Testing, Storage, and Stratification

This chapter summarizes current technology concerning cone collection and seed processing, testing, storage, and stratification for the six major conifer species—Douglas-fir, ponderosa pine, lodgepole pine, noble fir, white fir, and western hemlock -produced as seedlings in North - west bareroot nurseries. Though great advances have been made in the past 20 years, further refinements are deemed necessary to continue improving seedling-production technology, especially as use of valuable seed-orchard seed is favored ove r natural-stand seed.
