Shearing Systems for Fraser Fir (Abies fraseri) Christmas Trees [PDF]

open access: yesForests, 2018
Plantation-grown Fraser fir (Abies fraseri (Pursh) Poir.) Christmas trees were subjected to nine shearing regimes over nine years in a plantation in western North Carolina (USA). Treatments differed in the year of onset as well as the length of the residual leader (25 to 46 cm).

Sesquiterpene Induction by the Balsam Woolly Adelgid (Adelges piceae) in Putatively Resistant Fraser Fir (Abies fraseri)

open access: yesForests, 2022
Fraser fir, Abies fraseri (Pursh) Poir., is a tree endemic to the Southern Appalachians and is found only in a few isolated populations at high elevations. Fraser firs are also cultivated on a commercial scale as Christmas trees. The species is imperiled by an introduced insect, the balsam woolly adelgid, Adelges piceae Ratzeburg (BWA).

Morphology and foliar chemistry of containerized Abies fraseri (Pursh) Poir. seedlings as affected by water availability and nutrition [PDF]

open access: yesAnnals of Forest Science, 2010
We present the results of a two-year (2007-2008) greenhouse study investigating the effect of water availability and nitrogen fertilization on the growth, biomass partitioning, and foliar nutrient content of Abies fraseri (Pursh) Poir.* Fertilizer and moisture content (irrigation) were varied in a factorial experiment combining four levels of ...

Optimal Nutrition and Diagnosis for Abies fraseri Christmas Trees in Michigan [PDF]

open access: yesNorthern Journal of Applied Forestry, 2006
Abstract Fraser fir (Abies fraseri) is a species with a highly restricted native range that is now planted widely for Christmas tree production throughout the eastern US. The southeastern US has a long history of research on nutritional demands of Fraser fir, but growers in the Upper Midwest have limited locally based nutrition research ...

Recent results of Czech-American fir hybridization research

open access: yesJournal of Forest Science, 2013
Fraser fir (Abies fraseri) Christmas tree plantations in North Carolina are infested by root rot caused by Phytophthora cinnamomi. This disease kills almost 100% of Fraser fir material and leaves the soil permanently infested.
