Drying and Storing Stratified Loblolly Pine Seeds Reinduces Dormancy

Stratified pine seeds left over at the end of the sowing season must either be stored for 6 to 12 months or discarded. This article reports the effects of drying and storage on loblolly pine (Pinus taeda L.) seeds that had received several pregermination treatments. Six separate lots of loblolly pine seeds, ranging in age from 1 to 11 years, were divided and given five pregermination treatments (Barnett 1971). The treatments tested were: (1) cold stratification in polyethylene bags, (2) aerated cold-water soaks, (3) cold soaks with twice-weekly water changes, (4) unaerated soaks, and (5) no prechilling treatment. All treatments were at 41 F. for 147 days. After treatment, samples were drawn for initial testing and the remaining seeds were dried to to about 10 percent moisture content and stored at 34° F. for testing after 6 and 12 months.
