Size-Frequency Characteristics of Abies Fraseri Pollen as Influenced by Different Methods of Preparation

American Midland Naturalist, 1944
No study of the pollen grains of the southern balsam fir, Abies Fraseri (Pursh) Poir., from the highest mountains of Virginia, North Carolina, and Tennessee, has been published which would assist in the identification of the species in investigations of southern sedimenits.

Effect of root competition and nitrogen on growth and mineral content of Abiesfraseri

Canadian Journal of Forest Research, 1987
Three-year-old (3 + 0) Fraser fir seedlings (Abiesfraseri (Pursh) Poir.) were grown in a controlled-environment chamber under four N regimes, with and without root competition from orchard grass (Dactylisglomerata L.) or white clover (Trifoliumrepens L.). New shoot, stem, and root growth of Fraser fir were harvested 30, 60, and 90 days after budbreak.

Age-class differences in shoot photosynthesis and water relations of Fraser fir (Abies fraseri), southern Appalachian Mountains, USA

Canadian Journal of Forest Research, 2009
Fraser fir ( Abies fraseri (Pursh) Poir.) is an endemic tree species found only in refugial mountain-top forests in the southern Appalachian Mountains, USA. Very few studies have investigated the ecophysiology of this species in its natural environment.

Phenology and growth responses of Fraser fir ( Abies fraseri ) Christmas trees along an elevational gradient, southern Appalachian Mountains, USA

Agricultural and Forest Meteorology, 2017
Abstract Fraser fir (Abies fraseri) trees are endemic to locations above 1500 m in the southern Appalachian Mountains, and are also grown commercially for Christmas trees well below their native range (down to 600 m). To evaluate how phenology and growth of this species will respond to climate drivers associated with warming, we assessed the timing ...

Dormancy in Abiesfraseri seedlings at the end of the first growth cycle

Canadian Journal of Forest Research, 1982
Two experiments were conducted to examine the effect of chilling duration and postchilling photoperiod on breaking dormancy in Fraser fir (Abiesfraseri (Pursh) Poir.) seedlings. Chilling durations were 0, 2, 4, 6, 8, 10, or 12 weeks at 4 °C. Five postchilling photoperiods were used: 9, 12, 15, and 18 h, or a9-h natural day plus a3-h night light break ...

Growth and Ecophysiological Responses of Fraser Fir (Abies Fraseri) Christmas Trees Along an Elevational Gradient

Fraser fir (Abies fraseri) Christmas tree production is a $100 million dollar/year industry in North Carolina, but the future of these trees may be threatened by predicted global climate change. To evaluate how this species will respond to climate drivers associated with warming, I studied growth and ecophysiology of Fraser fir Christmas trees along an
