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.

Genomic variability in the vascular cambium of Abies balsamea

Canadian Journal of Botany, 1989
DNA content was measured cytophotometrically in Feulgen-stained nuclei of fusiform cambial initials from 1- (twig) and 19-year-old (stem base) cambia of balsam fir (Abies balsamea) trees throughout the season. Telophase (2C) and prophase (4C) DNA contents varied with both cambial age and time of year.

Sapin baumier -  Abies balsamea (L.) Mill

Hegel
Le sapin baumier (Abies balsamea (L.) Mill., Pinaceae) est une espèce de conifère dont l’oléorésine et les fractions aromatiques ont occupé une place importante dans les pratiques de soin traditionnelles, avant d’être intégrées à des usages domestiques, cosmétiques, parfumaires et thérapeutiques contemporains.

Phyllotactic patterns and transitions in Abies balsamea

Canadian Journal of Botany, 1985
Phyllotactic patterns, as indicated by the number of helices in opposed parastichy pairs, were determined in elongated shoots. Twelve patterns were found, including very rare patterns such as tetrajugy and secondary bijugy. Typically, the same pattern was repeated each year along a particular axis.

The hydraulic architecture of balsam fir (Abies balsamea)

Physiologia Plantarum, 1984
Leaf‐specific conductivities (LSCs – hydraulic conductivity per dry weight of supplied leaves). Huber values (transverse sapwood area per dry weight of supplied leaves), specific conductivity (hydraulic conductivity per transverse sapwood area) and tracheid diameters were measured throughout the trunk and crown of 20‐year‐old trees of Abies balsamca (L.

Factor in Abies balsamea Responsible for Coremia Formation of Ceratocystis piceae

European Journal of Forest Pathology, 1972
AbstractCompounds are present in sapwood of Abies balsamea (L.) Mill., triggering the formation of coremia by Ceratocystis piceae (Münch) Bakshi. From several unsaturated fatty acids, linoleic acid is the most active coremia inducer.
