Microsatellite analysis of Pinus taeda L. in Zimbabwe

Heredity, 2000
Deducing the origin of early 20th century introductions of Pinus taeda into Zimbabwe is possible given microsatellite markers and clear population differentiation in ancestral U.S. populations. This study was designed to determine whether P. taeda introductions into Zimbabwe came from one U.S.

Hexazinone influences on Pinus taeda seedlings

Forest Ecology and Management, 1990
Abstract Twenty 0.02-ha plots, established in the Georgia Piedmont to test the influence of hexazinone on Pinus taeda L. seedling growth and survival above that resulting from control of competing vegetation, were treated with four levels of hexazinone (0.0, 0.4, 0.9 and 1.3 kg/ha active ingredient) plus glyphosate for total weed control. After three

Root and stem partitioning of Pinus taeda

Trees, 2005
We measured root and stem mass at three sites (Piedmont (P), Coastal Plain (C), and Sandhills (S)) in the southeastern United States. Stand density, soil texture and drainage, genetic makeup and environmental conditions varied with site while differences in tree size at each site were induced with fertilizer additions. Across sites, root mass was about

Influence of soil porosity on water use in Pinus taeda

Oecologia, 2000
We analyzed the hydraulic constraints imposed on water uptake from soils of different porosities in loblolly pine (Pinus taeda L.) by comparing genetically related and even-aged plantations growing in loam versus sand soil. Water use was evaluated relative to the maximum transpiration rate (E crit) allowed by the soil-leaf continuum.

Comparing EST-based genetic maps between Pinus sylvestris and Pinus taeda

Theoretical and Applied Genetics, 2003
A genetic map of Pinus sylvestris was constructed using ESTP (expressed sequence tag polymorphism) markers and other gene-based markers, AFLP markers and microsatellites. Part of the ESTP markers (40) were developed and mapped earlier in Pinus taeda, and additional markers were generated based on P.

Loblolly Pine (Pinus taeda L.)

1991
Loblolly pine (Pinus taeda L.) is the leading commercial timber species in the southern United States. Carolus Linnaeus gave loblolly pine its scientific name, Pinus taeda, over 225 years ago. Taeda is the ancient name for resinous pines. It comes from the Latin, meaning torch.

Seasonal monoterpene and sesquiterpene emissions from Pinus taeda and Pinus virginiana

Atmospheric Environment, 2010
Abstract Seasonal volatile organic compound emission data from loblolly pine (Pinus taeda) and Virginia pine (Pinus virginiana) were collected using branch enclosure techniques in Central North Carolina, USA. P. taeda monoterpene emission rates were at least ten times higher than oxygenated monoterpene and sesquiterpene emissions in all seasons.

Inhibitory Effects of Myrica cerifera on Pinus taeda

American Midland Naturalist, 1995
-Pinus taeda naturally invades Myrica cerifera thickets as the shrub community succeeds to a maritime forest on southeastern USA barrier islands. Potential mechanisms supporting the persistence of M. cerifera thickets on barrier islands were examined in an environmental chamber. The inhibitory effects of allelochemicals from M. cerifera leaf litter and

Growth impact of O3, NO2 and/or SO2 on pinus taeda

Environmental Monitoring and Assessment, 1982
Seedlings of two full-sib families of loblolly pine expressing different degrees of sensitivity to O3 were exposed to 0.05 ppm O3, 0.10 ppm NO2, and/or 0.14 ppm SO2 for 6 hr/day for 28 consecutive days. The treatments were O3, NO2, SO2 (each used alone), O3+SO2, O3+NO2, and O3+NO2+SO2.

Modeling Seed Dispersal Distances: Implications For Transgenic Pinus Taeda

Ecological Applications, 2006
Predicting forest-tree seed dispersal across a landscape is useful for estimating gene flow from genetically engineered (GE) or transgenic trees. The question of biocontainment has yet to be resolved, although field-trial permits for transgenic forest trees are on the rise.
