Stratify Yellow-Popular Seed or Sow Directly?

A frequent topic of discussion among nurserymen in the Central States region is the best treatment for yellow-poplar seed before sowing. At the Marietta State Forest Nursery in Ohio, stratifying the seed in sand for one or more years has given the best results. On the other hand, State and Federal nurseries in Indiana and Illinois frequently sow seed of this species in the fall shortly after collection. This divergence of practices may be explained by a current source study of this species. The study shows that the best presowing treatment of yellow-poplar seed may vary by seed sources, conditions affecting seed formation and dormancy, or other factors not yet fully understood.
