Loblolly Pine
In tests with Pinus taeda L., most properties of wet. formed hardboard were improved by using fiber refined from wood having short, slender tracheids with thin walls. A theoretical analysIs suggested that the fibers fail in bending while under stress induced by the pressing operation. Such bending failures improve conditions for hydrogen bonding, thus improving board properties. Trachelds havmg...
متن کاملLoblolly Pine Ssr Markers for Shortleaf Pine Genetics
—Simple sequence repeats (SSR) are highly informative DNA-based markers widely used in population genetic and linkage mapping studies. We have been developing PCR primer pairs for amplifying SSR markers for loblolly pine (Pinus taeda L.) using loblolly pine DNA and EST sequence data as starting materials. Fifty primer pairs known to reliably amplify polymorphic markers in loblolly pine were scr...

Saucier-Susquehanna complex. Slope in this complex varies from 0 to 8%, but it was closer to 1–4% on the study site. Five treatments were established: (1) no cultivation or fertilization; (2) cultivated with no fertilization; (3) cultivated with a single application of 112 kg ha 1 of NPK fertilizer (type unknown); (4) cultivated with a single application of 224 kg ha 1 of NPK fertilizer; and (5...
متن کاملElectromagnetic Treatment of Loblolly Pine Seeds
Loblolly pine (Pinus taeda L.) is the species most frequently used for reforestation in the Southern United States; in fact, over 1 billion loblolly pine seedlings are produced each year for planting (McDonald and Krugman 1985). This has lead to a great deal of interest in any treatment that may have a potential to improve the survival and -early growth of this tree species. In the early 1970’s...
متن کاملLoblolly Pine - Pushing the Limits of Growth
The age of intensive plantation forestry in the Southeastern US rapidly approaches. Based on data through age 9 from loblolly pine plantations subjected to complete weed control and multiple fertilizations, growth rates to be expected equal or exceed those for southern pines grown in other countries under intensive cultural practices. Predictions of continuing growth through age 15 and economic...
