Torrefaction of Loblolly pine

Green Chem., 2012
The torrefaction of Loblolly pine (Pinus taeda) was examined at 250 and 300 °C, to determine the effects of treatment temperatures on the chemical structure of the torrefied Loblolly pine. Solid-state cross-polarization/magic angle spinning (CP/MAS) 13C nuclear magnetic resonance (NMR) spectroscopy was used to characterize the torrefied and native ...

Management of Loblolly Pine

Journal of Forestry, 1943
Abstract The following comments on Professor Chapman's bulletin on loblolly pine 1 are published as a contribution to our knowledge of the management of that species and also of the basic principles of forest management in general. The statement by Messrs.

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

Foliar nutrient comparisons of pitch pine, loblolly pine, and the pitch � loblolly hybrid

Plant and Soil, 1991
Foliar analysis was conducted to determine the differences between macronutrient concentrations and contents of current year's fascicles of loblolly pine (Pinus taeda L.), pitch pine (P. rigida Mill.), and first (F1) and second (F2) generation plantations of the pitch × loblolly hybrid (P. rigida × taeda). No significant differences in foliar P, K, Ca,

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 ...

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.

Pitch X Loblolly Pine Hybrids: Loblollies for the North?

Journal of Forestry, 1979
Abstract From controlled pollinations in a New Lisbon, New Jersey, orchard of selected pitch (Pinus rigida) and loblolly (P. taeda) pines, 29 test plantings have been made in nine states. Results indicate that well-formed, rapid-growing, winter-hardy trees can be produced by careful selection of parents and screening of hybrids.
