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.

Impacts of cloud immersion on microclimate, photosynthesis and water relations of Abies fraseri (Pursh.) Poiret in a temperate mountain cloud forest

Oecologia, 2008
The red spruce-Fraser fir ecosystem [Picea rubens Sarg.-Abies fraseri (Pursh) Poir.] of the southern Appalachian mountains, USA, is a temperate zone cloud forest immersed in clouds for 30-40% of a typical summer day, and experiencing immersion on about 65% of all days annually.

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

2016
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

In vitro studies of the impact of ozone and sulfur dioxide on the pollen of Fraser fir (Abies fraseri (Pursh) Poir.)

2014
The impact of in vitro ozone and sulfur dioxide fumigation on pollen from two Fraser fir populations was examined. Populations were located at Mt. Rogers, Va, and Mt. Mitchell, S.C.. Two age groups "young" (less then 30 years old) and "old" (more then 40 years old) were examined within each population. No statistically significant age group differences
