NMR studies on Fraser fir Abies fraseri (Pursh) Poir. lignins

Holzforschung, 2005
Abstract The composition of mature, juvenile uninfested and juvenile infested Fraser fir wood (Rotholz) and the structures of lignins isolated from these woods were elucidated to verify differences between juvenile and mature wood and the effect of balsam woolly adelgid (BWA) infestation.

Geographical variability of monoterpenes from Abies balsamea and A. fraseri

Phytochemistry, 1972
Abstract 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.

Structure and function of flexure wood in Abies fraseri

Tree Physiology, 1989
Wood 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 ...

Determination of volatile compounds in foliage of Fraser fir (Abies fraseri) and balsam fir (Abies balsamea)

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 ...

Cloud pattern and water relations in Picea rubens and Abies fraseri, southern Appalachian Mountains, USA

Agricultural and Forest Meteorology, 2012
Abstract The spruce-fir [Picea rubens Sarg.-Abies fraseri (Pursh) Poir.] forests of the southern Appalachian Mountains are considered refugial, endangered communities that exist on only seven mountaintop areas in Virginia and North Carolina, USA. These relict forests continue to be threatened by stress factors such as logging, acid rain deposition ...

Experimental cloud immersion and foliar water uptake in saplings of Abies fraseri and Picea rubens

Trees, 2013
Frequent 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.
