Repellent-Coated Seed of Loblolly Pine can be Stratified

Germination of unstratified, repellent-coated seed of loblolly pine is often slow and irregular, increasing the chance of depredation and causing irregularity in the density of the resulting stands. Therefore, more seed is required to insure a full stand. At planting, the moisture content of repellent-coated seed must be increased so that the seeds will germinate promptly, especially if they have been redried and stored. Adding moisture to such seed poses problems because the repellents can be toxic to the forthcoming radicle.2 A study just completed shows not only that it is possible to stratify repellent-coated seed of loblolly pine safely, but also that stratification is necessary to obtain maximum germination and an increase in speed of germination.
