The Demographic Cost of Reproduction and Its Consequences in Balsam Fir (Abies balsamea)

The American Naturalist, 1999
It is an axiom of life-history theory that reproduction involves age-specific costs in terms of survival or future reproduction. The measurement of costs of reproduction in plants is difficult, and few field studies have measured these costs in terms of fitness or demographic components, thus creating a hiatus between theory and data.

Enhanced growth and ethylene increases spiral grain formation in Picea abies and Abies balsamea trees

Trees, 2002
Spiral grain angle in Norway spruce (Picea abies) trees and balsam fir (Abies balsamea) seedlings was investigated in relation to growth rate, endogenous and applied ethylene. Trees from stands of Norway spruce, which were irrigated and fertilised in order to enhance growth, and trees having different growth rates in non-treated stands were studied ...

Identification of abscisic acid in Abies balsamea

Phytochemistry, 1972
Abstract Abscisic acid was positively identified in dormant buds of the conifer Abies balsamea on the basis of chromatographic behavior, inhibition in a bioassay, and mass spectrometry. Sublimation was a valuable adjunct to chromatographic separation techniques.

Rest in the cambium of Abies balsamea

Canadian Journal of Botany, 1974
Cuttings were collected from the field between September and May, when buds and cambia are dormant, and were placed under favorable conditions in environmental cabinets. Radial width of new xylem, measured at the midpoint of the cuttings, was used to indicate cambial activity.In bud-bearing cuttings, cambial activity was associated with bud activity ...

Composition and antibacterial activity of Abies balsamea essential oil

Phytotherapy Research, 2006
AbstractThe antibacterial activity of the essential oil of Abies balsamea (balsam fir) was evaluated against Escherichia coli and Staphylococcus aureus. The essential oil of A. balsamea was found to be inactive against E. coli (>100 µg/mL) and active against S. aureus, with an MIC of 56 µg/mL.

Breadstuff from fir (Abies balsamea)

Economic Botany, 1970
While many a professor has undertaken a study or written a book to fill the needs of his students, my work has grown out of the popular interest of families, most of them transplanted into a near-wilderness from urban centres of Canada and abroad. Thus, while so many economic botanists are concentrating on explorations of new territories and resources,

Effects of volatile substances released by foliage of Abies balsamea

Journal of Invertebrate Pathology, 1972
Abstract The principal substances released by the foliage of Abies balsamea (pinene α and β, limonene, phellandrene, fenchone, and thujone) were tested on a few entomopathogenic species of Bacillus “cereus group” and on several common bacteria such as Escherichia coli, Pseudomonas sp., and Staphylococcus sp. E. coli proved to be the most resistant of

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.
