Diterpenes from pinus taeda

Phytochemistry, 1998
Abstract Solvent partition and chromatographic fractionation of the wood of Pinus taeda afforded a mixture of aliphatic ketones and esters, sitosterol, stilbene and five diterpenes namely, pimaric acid, isopimaric acid, dehydroabietic acid, 12 α ,13 β -dihydroxyabiet-8(14)-en-18-oic acid and 7 α ,9 α ,11 α -trihydroxyabiet-8(14)-en-18-oic acid.

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.

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

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.

Abscisic acid and zygotic embryogenesis in Pinus taeda

Tree Physiology, 1995
Indirect ELISA was used to quantify (+)-abscisic acid (ABA) in developing zygotic embryo and megagametophyte tissues from two loblolly pine (Pinus taeda L.) mother trees. On a dry weight basis, embryonic and megagametophytic ABA concentrations were highest during early development and decreased steadily to their lowest values at cone ripening ...

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
