A Tarif System for Loblolly Pine

Forest Science, 1985
Abstract The volume/basal area line, as the basis of a tarif system for natural and planted stands of loblolly pine in North and South Carolina, Georgia, and north Florida, is discussed and shown to be inappropriate. A new method of developing tarif tables is presented, using a nonlinear volume-dbh function harmonized by mean stand ...

Root-Grafting in Loblolly Pine

Botanical Gazette, 1965
Living loblolly pine stumps (Pinus taeda L.) appear to be relatively uncommon, but not rare. Excavation of roots and application of a P32 solution to two living stumps showed that they were connected with living trees by means of natural root grafts formed some time before the trees reached 35 years of age.

Observations on pollination in loblolly pine

Canadian Journal of Forest Research, 1987
Insitu observations of Pinustaeda L. strobili in a 26-year-old grafted seed orchard showed that emergence of pollination droplets began on unpollinated strobili as they approached full receptivity and declined thereafter. Droplets reemerged throughout the receptive period primarily during the early morning or evening until pollinated, after which they

Storing Loblolly Pine Pollen

Southern Journal of Applied Forestry, 1991
Abstract A series of controlled-pollination tests with fresh pollen and pollen stored for up to 10 years demonstrates the conditions required to maintain high pollen viability and vigor. During handling, freshly extracted pollen is highly resistant to exposure to temperatures up to 50°C for as long as 24 hours.

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.

Loblolly pine bark polyflavanoids

Journal of Agricultural and Food Chemistry, 1980
The inner bark of Pinus taeda L. contains (+ )-catechin, the procyanidin 8.1 (a C-4 to C-8 linked (-)-epicatechin to (+)-catechin dimer), and three polymeric procyanidins that have distinctly different solubility and chromatographic properties. An ethyl acetate soluble polymer (0.20% of bark, Mft = 1200) was purified by chromatography on LH-20 Sephadex.

Loblolly -- the pine for the twenty-first century

New Forests, 1999
Loblolly pine (Pinus taeda L.) was a minor component of the vast natural forests of the southern United States before the region was settled by immigrants. Extensive planting and natural regeneration of cutover forest land and abandoned farmland between 1930 and 1990 made loblolly the leading timber species in the United States.

Loblolly Pine Seed Dispersal

Journal of Forestry, 1938
Abstract During the fall and winter of 1936-37 fifty seed traps, set up in a Latin square design in and adjacent to a 70-year-old loblolly pine stand in the Duke Forest, Durham, N. C., were examined weekly. Loblolly pine seed fall started on October 14, 1936 and continued until the week of June 23, 1937.

Breeding Shortleaf × Loblolly Pine Hybrids for the Development of Fusiform Rust-Resistant Loblolly Pine

Southern Journal of Applied Forestry, 1986
Abstract A fusiform rust-resistant strain of loblolly pine (Pinus taeda L.) is being developed by interspecific hybridization with shortleaf pine (P. echinata Mill.). Backcrosses of the hybrid to loblolly pine have early height growth equal to loblolly pine and retain a high level of fusiform rust resistance.

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 ...
