Electromagnetic 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
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 کاملDistinguishing features of loblolly and shortleaf pine seeds : implications for monitoring seed production in mixed stands
Monitoring seed production in mixed loblolly pinc shortlcaf pine (Pinus taeda L. and Pinus echinata Mill.. respectively) stands may require identifying individual weds hy species. Althuugh lublully pine seeds are UII average Ileavier and larger than thosc of shortleaf pine. there is considerable overlap in these properties for individual seeds. In this study the properties of six seer1 lnrs of ...
متن کاملAbnormal lignin in a loblolly pine mutant.
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 pathway, is the major component of the mutant's lignin, accounting for approxima...
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...
