Using silvicultural practices to regulate competition, resource availability, and growing conditions for Pinus palustris seedlings underplanted in Pinus taeda forests
In the southeastern United States, many forest managers are interested in restoring longleaf pine (Pinus palustrisMill.) to upland sites that currently support loblolly pine (Pinus taeda L.). We quantified the effects of four canopy treatments (uncut Control; MedBA, harvest to 9 m2·ha−1; LowBA, harvest to 5 m2·ha−1; and Clearcut) and three cultural treatments (NT, no treatment; H, herbicide rel...
متن کاملIntrogression between Pinus taeda L. and Pinus echinata Mill
Loblolly pine (Pinus taeda L.) and shortleaf pine (Pinus echinata Mill.) have widely overlapping geographic ranges. Hybridization between the two species has interested tree breeders for a long time. Morphologically, the two pine species are different. The needles of loblolly pine are 6 to 9 inches long, usually with three yellow-green needles per fascicle; but shortleaf pine needles are 3 to 5...
متن کاملNutrient use and uptake in Pinus taeda.
We quantified nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) content, use (nutrient amount for one growth year), retranslocation (nutrients recycled before foliage senescence), uptake (use minus retranslocation), volume production per unit of uptake and fertilizer-uptake efficiency (percent applied taken up) in a 2 x 2 (nutrient and water) factorial experiment repl...
متن کاملXIII Genetic Transformation of Pinus palustris
Longleaf pine (Pinus palustris Mill.) is an important softwood species in the southeast United States. In presettlement times, this species occupied extensive, pure stands throughout the Atlantic and Gulf Coastal Plains from southeastern Virginia to eastern Texas, as well as south throughout the northern two-thirds of Florida. Its range also includes the Piedmont Ridge and Valley, and Mountain ...
متن کاملPhytochrome in Embryos of Pinus palustris.
Phytochrome has been shown to be involved in the germination of seeds of a number of pine species as determined by the responses of these seeds to red and far-red irradiations (4, 7, 9). Nyman (7) found that even before imbibition, germination of Pinits silvestris seeds can be promoted by red irradiation. McLemore (5) found that germination of longleaf pine seed (P. palustris) can be repeatedly...
