Precommercial Thinning of Loblolly Pine
Journal of Forestry, 1969Abstract Machine and hand thinnings beginning at age 7 increased height growth and yield in an overly dense loblolly pine (Pinus taeda L.) stand. In order to be most profitable, it appears that precommercial thinning should be done by machine at age 2 or 3 to at least an 8- by 8-foot spacing.

Reaction kinetics of hydrothermal carbonization of loblolly pine
Bioresource Technology, 2013Hydrothermal carbonization (HTC) is a pretreatment process to convert diverse feedstocks to homogeneous energy-dense solid fuels. Understanding of reaction kinetics is necessary for reactor design and optimization. In this study, the reaction kinetics and effects of particle size on HTC were investigated.

A Laccase Associated with Lignification in Loblolly Pine Xylem
Science, 1993Peroxidase has been thought to be the only enzyme that oxidizes monolignol precursors to initiate lignin formation in plants. A laccase was purified from cell walls of differentiating xylem of loblolly pine and shown to coincide in time and place with lignin formation and to oxidize monolignols to dehydrogenation products in vitro.

Loblolly pine arginase responds to arginine in vitro
Planta, 2003Following germination of loblolly pine (Pinus taeda L.) seeds, storage proteins in the embryo and megagametophyte are broken down to provide nitrogen, in the form of amino acids, to the developing seedling. A substantial portion of the free amino acids released in this process is arginine. Arginine is hydrolyzed in the cotyledons of the seedling by the

Xylem-specific gene expression in loblolly pine
Plant Molecular Biology, 1995Two 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.

Growth of Loblolly Pine in Uruguay
Journal of Forestry, 1969Abstract In order to determine differences in rates of growth of the terminal shoots, 7 lots of Pinus taeda L., each from a different geographic source, and one of P. serotina Michx. were measured at intervals during one growing season in Uruguay.

Response of Loblolly Pine to Thinning
Journal of Forestry, 1952Abstract How and when should loblolly pine be thinned? This study suggests that thinning practices best suited to sawlog production are not necessarily the most profitable where pulpwood is the main objective.
