Viability of Cottonwood Seeds in Relation to Storage Temperature and Humidities

Because of its fast growth and high yields cottonwood (Populus deltoides Bartr.) is an important bottomland hardwood in eastern United States. In recent years considerable attention has been directed towards problems encountered in the production of cottonwood seedlings. Cottonwood seeds are notoriously short lived when stored at room temperatures and humidities. For this reason nurserymen commonly collect seeds and plant them immediately. However, in the northern part of the range of this species the seeds mature so late (June, July and August) that plantable seedlings cannot be grown in one year. Twoyear-old seedlings are more costly and often too large to plant efficiently. A satisfactory solution to this problem seems to hinge on earlier nursery seeding, and earlier seeding depends on carrying viable seed from one year to the next.
