Response of Longleaf Pine Seeds to Storage Conditions and Pregermination Treatments
Abstract:Although longleaf pine (Pinus palustris Mill.) seeds are considered the most susceptible of the southern pines to damage during collection, processing, and storage, results of these studies show that high seed quality can be assured for periods up to 20 yr through proper handling and storing techniques. Recommendations for long-term storage include drying seeds to moisture contents of 10% or less and storing at subfreezing temperatures, preferably near 0°F. Reevaluation of stratification treatments applied under operational conditions indicates that the soaking in water that is necessary for seed imbibition reduces total germination in an amount proportional to the length of the soak. Stratification is not recommended except under very controlled conditions. South. J. Appl. For. 17(4):174-179.
