Since 2009, deployment of full-sib families of loblolly pine (Pinus taeda L.) has gained prominence in the southeastern United States. To produce full-sib seed, a pollination bag is used to isolate female strobili from outside pollen contamination, a

A southwide efficacy test of reduced rates of azinphosmethyl (Guthion®) for control of seed and cone insects in loblolly pine seed orchards was conducted in 1992. In each of nine loblolly pine (Pinus taeda L.) seed orchards, an untreated (no protect

The phenology of 5- and 6-year old loblolly pine (Pinus taeda L.) trees was studied over two different growing seasons (1993 and 94) in southwest Georgia. These trees were from 7–9 open-pollinated families from each of four different provenances pl

Contributions of sites, rootstocks, and scion clones (and the interactions between these factors) to scion growth and reproduction were studied in loblolly pine (Pinus taeda L.). Twenty-five full-sib families were used as rootstocks. Six scion clones

When grown together in plantations, fast-growing southern and coastal sources of loblolly pine (Pinus taeda L.) often have lower wood specific gravity than northern and inland sources. This study investigated whether this phenomenon could be explaine

Open-pollinated Fraser fir (Abies fraseri [Pursh] Poir.) progeny from several elevations on each of 5 mountain sources were assessed at 8 yr (rotation age) for growth and quality traits. Seed sources varied significantly in total height, crown diamet

Wholesale values, retail values of five eastern United States lots, U.S. Dept. of Agriculture (USDA) Christmas-tree grades, and measurements of various growth and quality traits were obtained on ≥1400 Fraser fir [Abies fraseri (Pursh) Poir.] (8 yea

Open-pollinated progeny trials of Fraser fir (Abiesfraseri (Pursh) Poir.) assessed at 8 years provided genetic parameter estimates for growth, Christmas tree quality traits, and wholesale value at harvest age. Significant variation was found between

In 1991, a Southwide study to evaluate the efficacy of bifenthrin (Capture®) for cone and seed insect control was established in six loblolly pine (Pinus taeda L.) and three slash pine (P. elliottii Engelm.) seed orchards. A control (no treatment),
