Effects of cone storage on seed quality were evaluated in studies conducted in Mississippi and Alabama on drying rates and storage conditions (bag vs. crate). The drying study found that: (1) Cone drying was equally rapid in indoor and outdoor covered conditions and slower in unprotected outdoor conditions; (2) seed extraction efficiency was significantly affected by all treatments with the best efficiency from cones stored outdoors unprotected; and (3) germination rate was more sensitive to treatment conditions than total germination. The second study compared burlap bags to 20-bushel wirebound crates as storage containers for loblolly (Pinustaeda L.) or slash (P. elliottii Engelm.) pine cones stored for varying periods. Study results reveal that (1) either bags or crates provide satisfactory storage if handled properly and (2) cone storage (4 weeks for slash, 5 to 7 weeks for loblolly) enhances seed quality through apparent improved maturation.
