Structure and function of flexure wood in Abies fraseri
Tree Physiology, 1989Wood produced during flexure in one-year-old leaders of Abies fraseri (Pursh) Poir. (Fraser fir) was analyzed anatomically and radio-densitometrically. More xylem cells were produced in stems subjected to flexing than in stems that were not flexed. The lumens of tracheids produced in response to flexure were smaller than the lumens of tracheids in ...

Fraser Fir (Abies fraseri [Pursh] Poir.)
Forestry Sciences, 2018Fraser fir ( Abies fraseri [Pursh] Poir.) is a coniferous species native to the Southern Appalachian Mountains of the Eastern United States. Fraser fir has high economic and recreational value but is vulnerable to extinction due to introduced pests and global warming.

Abies fraseri (Pursh) Poir. (Fraser Fir)
Biotechnology in Agriculture and Forestry, 1996The genus Abies Mill. (firs) is one of the largest in the Pinaceae (Krussman 1985). Liu (1971) provided a taxonomic monograph of the genus Abies, and reported that it included two subgenera with 15 sections composed of 39 species, 27 varieties, and 9 hybrids.

Experimental cloud immersion and foliar water uptake in saplings of Abies fraseri and Picea rubens
Trees - Structure and Function, 2013Frequent cloud immersion events result in direct uptake of cloud water and improve plant water potentials during daylight hours in saplings of two dominant cloud forest species. In ecosystems with frequent cloud immersion, the influence on plant water balance can be important.

Geographical variability of monoterpenes from Abies balsamea and A. fraseri
Phytochemistry, 1972Abstract Nearly 300 trees of Abies balsamea and A. fraseri from 29 locations covering the entire ranges of these species were examined for composition of their cortical monoterpenes. Eastern A. balsamea was intermediate in terms of most of its monoterpenes, with A. fraseri and western A. balsamea representing two opposite chemical extremes.

Physiologia Plantarum, 1986
Field‐ and greenhouse‐grown Abies fraseri (Pursh) Poir. (Fraser fir) were analyzed for wind‐ or mechanically‐induced flexure changes. These changes included inhibition of stem and needle elongation, reinforcement of branch bases around the stem, and increased radial growth in the direction of the mechanical perturbation (MP).

Microchemical Journal, 2006
Abstract The Fraser fir ( Abies fraseri ) and balsam fir ( Abies balsamea ) are eastern North American conifers which have been infested by an exotic insect, the balsam woolly adelgid (BWA). BWA infestation has had particularly severe effects on Fraser fir, with up to 95% mortality rates at some sites, and is characterized by attack on mature trees ...

Effects of nitrogen form on nutrient uptake and physiology of Fraser fir (Abies fraseri)
Forest Ecology and Management, 2005Abstract Shade-tolerant conifer species are generally thought to prefer NH 4 + as a source of inorganic N and may perform poorly on recently disturbed sites or agricultural soils with high rates of nitrification. Fraser fir ( Abies fraseri ) is a highly shade-tolerant climax species characteristic of acidic forest soils that is now planted on a ...
