Bending properties of loblolly pine

Industrial Crops and Products, 2017
Abstract A three-point bending test was used to assess the effects of moisture content, radial location, and tree height on the specific toughness and bending stress of loblolly pine. Test samples were collected at 20%, 40%, 60%, and 80% of the radial distance between the tree pith and bark, across four heights (0 mm/tree base, 116.84 mm/breast ...

Biomass production of loblolly pine seeded between rows of planted loblolly pine

Biomass and Bioenergy, 1993
Abstract A dual-cropping concept was tested by growing loblolly pine ( Pinus taeda L.) for energy biomass in normally unused space between rows of a newly established pine plantation. Loblolly pine seeds were spot seeded in a 1.5 m wide swath between the planted rows of loblolly pine seedlings planted at 2 by 3 m spacing.

Abnormal Lignin in a Loblolly Pine Mutant

Science, 1997
Novel lignin is formed in a mutant loblolly pine ( Pinus taeda L.) severely depleted in cinnamyl alcohol dehydrogenase (E.C. 1.1.1.195), which converts coniferaldehyde to coniferyl alcohol, the primary lignin precursor in pines. Dihydroconiferyl alcohol, a monomer not normally associated with the lignin biosynthetic

Carbon cycling in a loblolly pine plantation

Oecologia, 1977
The carbon cycle of a loblolly pine plantation in North Carolina was examined during its 12th through 16th years from planting. Net primary production during the study period averaged 2056 g C m-2 year-1. With autotrophic respiration equal to 2068 g C, the calculated gross production was 4124 g C m-2 year-1.

Xylem-specific gene expression in loblolly pine

Plant Molecular Biology, 1995
Two genes preferentially expressed in differentiating xylem of loblolly pine (Pinus taeda L.) were cloned from cDNA and genomic libraries and designated PtX3H6 and PtX14A9. Transcripts of PtX3H6 and PtX14A9 are very abundant in differentiating xylem, less abundant in needles, and very low or non-detectable in embryos and megagametophytes.

Competitive responses of loblolly pine to gradients in loblolly pine, sweetgum, and broomsedge densities

Canadian Journal of Forest Research, 1993
A factorial combination of 0, 1, 2, and 4 loblolly pine (Pinustaeda L.) seedlings and sweetgum (Liquidambarstyraciflua L.) sprouts, and 0, 4, and 16 broomsedge (Andropogonvirginicus L.) seedlings per square metre were used to determine the nature of pine response to competition (competitive response) from multiple life forms during the first season ...

Loblolly Pine (Pinus taeda L.)

1991
Loblolly pine (Pinus taeda L.) is the leading commercial timber species in the southern United States. Carolus Linnaeus gave loblolly pine its scientific name, Pinus taeda, over 225 years ago. Taeda is the ancient name for resinous pines. It comes from the Latin, meaning torch.

Early genetic evaluation of loblolly pine

Canadian Journal of Forest Research, 1981
Seedlings of five known fast-growing, open-pollinated loblolly pine (Pinustaeda L.) families and five known slow-growing families were grown from seed to 24 weeks of age in a greenhouse. Each family was subjected to four moisture regimes ranging from high stress levels to little or no stress.

Yield Estimates for Loblolly Pine Plantations

Journal of Forestry, 1979
Abstract Three stand models, representing a range of alternatives for loblolly pine (Pinus taeda L.) yield estimation, were evaluated and compared with independent data on the basis of merchantable cubic-foot yield estimates. The comparisons included a multiple regression model, a diameter distribution model, and an individual-tree ...

Loblolly Pine Regeneration from Seed

Journal of Forestry, 1963
Abstract The paper describes a 7-year study in the coastal plain of North Carolina integrating common cultural methods with dollar costs and percent increase in natural loblolly pine stocking. On heavy textured soils, neither burning nor disking can be economically justified.
