Interim Guidelines for Growing Longleaf Seedlings in ContainersThis article is part of a larger document. View the larger document here.
The demand for container longleaf pine (Pinus palustris Mill.) planting stock continues to increase each year. A problem facing both producers and users of container seedlings is the lack of target seedling specifications. Outplanting and evaluating performance of seedlings with a range of physiological and morphological characteristics, over a number of years, and on a wide range of sites is needed to have sufficient data to develop optimum seedling criteria. Since resources have been unavailable to conduct this needed research, we have canvassed the producers and users of longleaf container stock for their recommendations on what they consider "preferred" and "not acceptable" planting stock. The compilation of this information has been widely reviewed and all suggested revisions considered. These standards are proposed as guidance until research provides sufficient data to modify and upgrade the specifications.
