Vegetative Propagation of Abies fraseri by Stem Cuttings1

HortScience, 1980
Abstract Rooting of Fraser fir [ Abies fraseri (Pursh) Poir.] stem cuttings decreased as stock plant age increased from 5 to 12 to 22 years. Indolebutyric acid (IBA) at 5000 ppm increased rooting of cuttings from 12- and 22-year old trees.

Refugial forests of the southern Appalachians: photosynthesis and survival in current-year Abies fraseri seedlings [PDF]

Tree Physiology, 2005
Fraser fir (Abies fraseri (Pursh) Poiret) is an endemic, high-elevation conifer confined to six relict mountaintop communities in the southern Appalachian Mountains, USA. High adult mortality has occurred over the past 50 years, possibly the result of an introduced insect (Adelges piceae Ratzeburg), air pollution, or both.

Propagation of Abies fraseri by Semidormant Hardwood Stem Cuttings

HortScience, 1985
Abstract Dormant hardwood stem cuttings of Fraser Fir [ Abies fraseri (Pursh) Poir.] were severed from upper and lower tree crowns and artificially chilled at 4°C for 0, 4, or 8 weeks to achieve a partial break in rest. Following chilling, the resulting semi-dormant cuttings

Thyronectria balsamea on Abies fraseri in Pennsylvania and North Carolina

Plant Disease, 1997
In August 1996, several 4- to 6-m-tall Abies fraseri (Pursh) Poir. in Adams County, PA, were found bearing numerous dead branches and/or dead tops. The trees had been severely stressed by being ball-and-burlapped and replanted in 1993. Distinct cankers occurred between the living and dead portions of stems and branches.

Isolation and characterization of microsatellite markers in Fraser fir (Abies fraseri) [PDF]

Molecular Ecology Notes, 2005
AbstractWe describe the isolation and characterization of 14 microsatellite loci from Fraser fir (Abies fraseri). These markers originated from cloned inserts enriched for DNA sequences containing tandem di‐ and tri‐nucleotide repeats. In total, 36 clones were selected, sequenced and evaluated.
