An undescribed needle nematode (Longidorus sp.) was consistently associated with stunted loblolly pine seedlings at the Flint River Nursery in south Georgia. Seedlings in affected areas had root systems that were greatly reduced in size, and lacked lateral and fine roots. In a growth chamber…

Continuing to fertilize bareroot and container seedlings during the hardening process (from cessation of height growth until lifting) can improve seedling viability. The process of fertilizing during hardening has many names, but in the last decade a new term, nutrient loading, has come into use.…

Random amplified polymorphic DNAs (RAPDs) were used to construct linkage maps of the parents of a longleaf pine (Pinus palustris Mill.) slash pine (Pinus elliottii Englm.) F1 family. A total of 247 segregating loci [233 (1:1), 14 (3:1)] and 87 polymorphic (between-parents), but non-segregating,…

Random amplified polymorphic DNA (RAPD) markers were employed to map the genome and quantitative trait loci controlling the early growth of a pine hybrid F1 tree (Pinus palustris Mill. × P. elliottii Engl.) and a recurrent slash pine tree (P. ellottii Engl.) in a (longleaf pine × slash pine) ×…

Longleaf pine (Pinus pulustris Mill.) ecosystems once occupied over 36 million hectares in the southeastern United States lower coastal plain. These fire-dependent ecosystems dominated a wide range of coastal plain sites, including dry uplands and low, wet flatlands. Today, less than 1.3 million…

We provide basic guidelines for nursery production of longleaf pine ( Pinus palustris P. Mill. [Pinaceae]) seedlings in containers. The best seedlings are spring sown, grown outdoors in full sun in cavities with a 100-ml (6 in3) volume, 11-cm (4.5 in) depth, and a density around 535 seedlings…

The objective of this study was to investigate the influence of the phenol-formaldehyde resin content level (3 percent and 7 percent), and three fungi species (Poria placenta, Gleophyllum trabeum, and Polyporus versicolor) on the dimensional stability and decay resistance of high density…

The importance of lightning as an ignition source for the fire driven Pinus palustris ecosystem is widely recognized. Lightning also impacts this system on a smaller scale by causing individual tree mortality. The objective of this study was to determine the level of mortality due to lightning…

Research has developed guides for consistent natural regeneration of longleaf pine by a shelterwood system. Key measures include hardwood control by fire and other means, timely preparatory and seed cuts, seed crop monitoring, seedbed preparation, protection of established seedlings, prompt removal…
