Loblolly pine (Pinus taeda L.) exhibits genetic resistance to fusiforrn rust disease (incited by the biotrophic fungus, Cronartiurn quercuum f. sp. fusifom) and pitch canker disease (incited by the necrotrophic fungus, Fusarium circinatum). In this study, a total of 14,015 loblolly pine cuttings from 1,065 clones were screened in controlled greenhouse conditions to identify phenotypes of clones...

The relationship between soil water availability, root extension, and shoot growth of lohlolly pine seedlings (Pinus taedu L.) was evaluated in a rhizotron sand mixture in the absence and presence of crabgrass (Digitaria spp.) competition. Heights and diameters of seedlings grown with crabgrass were reduced 33 and SO%, respectively, compared with seedlings grown in pine monoculture. Furthermore...

-We evaluated selection of nest sites by male Red-cockaded Woodpeckers (Picoides borealis) in Texas relative to the age of the cavity when only cavities excavated by the woodpeckers were available and when both naturally excavated cavities and artificial cavities were available. We also evaluated nest-cavity selection relative to the ability of naturally excavated cavity trees to produce resin,...

Loblolly pine ( Pinus taeda L.) productivity over the past century has increased significantly from genetic improvements and more intensive management practices. The current study concludes a series of assessments loblolly growth/physiological responses to continuous resource treatments weed control (W), plus irrigation (WI), fertigation (WIF). Increment cores were analyzed by X-ray densitometr...

A number of recent studies have shown reduced individual-tree growth throughout the 1970s and early 1980s in natural loblolly pine (Pinus raeda L.) stands in the southeastern United States. This study updates radial growth trends of loblolly pine in the Virginia Coastal Plain through 1989. Ring-width series were initially grouped into two age-classes (~50 or 150 years) and a clustering procedur...

[1] In two parallel but independent experiments, Free Air CO2 Enrichment (FACE) technology was used to expose plots within contrasting evergreen loblolly pine (Pinus taeda L.) and deciduous sweetgum (Liquidambar styraciflua L.) forests to the level of CO2 anticipated in 2050. Net primary production (NPP) and net ecosystem production (NEP) increased in both forests. In the year 2000, after expos...

Loblolly pine (LBP; Pinus taeda L.) stands provides two-thirds of the existing federally protected red-cockaded woodpecker (RCW; Picoides borealis) habitat in Fort Benning, Georgia, USA. However, LBP in this area is suspected to face a forest decline issue, which may risk the sustainability of the RCW population. Land managers are attempting to convert LBP stands to longleaf pine (Pinus palustr...
