Container-Grown Longleaf Pine Seedling QualityThis article is part of a larger document. View the larger document here.
This study examines the comparative hardiness of various classes or grades of container-grown longleaf pine (Pinus palustris Mill.) seedlings. Most container longleaf seedlings are grown in small ribbed containers averaging 5 to 7 cubic inches in volume and 3 to 6 inches in depth. Great variability is often exhibited in typical lots of container-grown longleaf pine seedlings. Longleaf seedlings are usually sold on a per-thousand basis and an average lot of 1000 seedlings will contain “good” or “target” seedlings, “doubles” (two seedlings per plug), “floppies” or “culls”, and “sonderegger” (hybrid loblolly x longleaf) seedlings. This study examines the relative survival rates of these four seedling types in the first growing season.
