Storage of Longleaf Pine Seed

Studies by the Alexandria Research Center show that vigor and viability of longleaf pine seed can be preserved for at least 5 years if the seed is stored at the correct tem-perature and moisture content. Barton (1), Nelson (2), and Wakeley (3) found that low temperature and low moisture content are essential to longleaf seed storage. Their work did not include field germination, which is of great importance in direct seeding. Use of seed that had deteriorated in storage caused several failures in early seeding attempts and led to the widespread belief that only fresh seed should be sown. Consequently, three studies1 were started to determine optimum conditions for longleaf seed storage and the interrelationship between temperature and seed moisture content. All studies are continuing.
