Regenerating eastern white pine: A cooperative research approach

Regenerating Shortleaf Pine: Results of a 5-year Cooperative Research Initiative

—Shortleaf pine (Pinus echinata Mill.) is unique among the southern pines. It has the widest natural range and thrives on shallow rocky soils of the Interior Highlands, where most other pine species perform poorly. Although wood quality is excellent, it has been one of the most neglected species from both research and operational standpoints. It has a history of poor performance following outpl...

A New Stocking Guide Formulation Applied to Eastern White Pine

A procedure is described for incorporating stand age, or stage in development, into the widely used stocking guides based on the crown competition factor (CCF). A simple model that predicts dbh of individual trees from crown projection area and total height is derived from a three-dimensional relationship between cumulative foliage production (crown volume) and total volume of the main stem. Pr...

Histology of White Pine Blister Rust in Needles of Resistant and Susceptible Eastern White Pine

Characterization of microsatellite markers in eastern white pine.

An enrichment cloning method was evaluated for the isolation of microsatellite loci from eastern white pine and the resulting markers were examined for polymorphisms. A 200-fold enrichment was achieved for highly abundant (AC)n repeats, but for much less abundant (ACAG)n repeats an enrichment of only 20-fold was obtained. Using a single set of PCR conditions, 19 microsatellite loci were identif...

Epicuticular Wax and White Pine Blister Rust Resistance in Resistant and Susceptible Selections of Eastern White Pine (Pinus strobus).

ABSTRACT Epicuticular wax on needles was evaluated for its influence on Cronartium ribicola infection of resistant and susceptible selections of Pinus strobus. Environmental scanning electron microscopy comparisons revealed that needles from a resistant selection of eastern white pine, P327, had a significantly higher percentage of stomata that were occluded with wax, fewer basidiospores germin...
