Somatic embryogenesis in cultured mature zygotic embryos of Abies balsamea
Plant Cell, Tissue and Organ Culture, 1994Embryo suspensor masses (ESMs) were induced by culture of isolated mature zygotic embryos of balsam fir [Abies balsamea (Mill.)] on media containing 10 μM cytokinin [6-(γ-γ-dimethylallylamino)purine (2iP), 6-benzyladenine (BA), or thidiazuron (TDZ)].

Ethylene in relation to compression wood formation in Abies balsamea shoots
Trees, 1999The terminal (1-year-old) shoot of dormant, 2-year-old balsam fir [Abies balsamea (L.) Mill.] seedlings was either left vertically oriented or tilted to an angle of 60° from the vertical (tilting experiment), or was ringed with N-1-naphthylphthalamic acid (NPA), an inhibitor of indole-3-acetic acid transport, at a concentration of 0, 1 or 10 mg g−1 ...

Chemical composition of the cortical essential oil from Abies balsamea
Phytochemistry, 1974Abstract Monoterpenoids and sesquiterpene hydrocarbons of Abies balsamea cortical oleoresin (Canada balsam) were analyzed by a combination of chromatographic and spectroscopic methods. Monoterpene hydrocarbons (21%) were composed of β-pinene, α-pinene, β-phellandrene, limonene, 3-carene, myrcene and camphene (listed in order of decreasing ...

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 ...

Microchemical Journal, 2006
Abstract The Fraser fir ( Abies fraseri ) and balsam fir ( Abies balsamea ) are eastern North American conifers which have been infested by an exotic insect, the balsam woolly adelgid (BWA). BWA infestation has had particularly severe effects on Fraser fir, with up to 95% mortality rates at some sites, and is characterized by attack on mature trees ...

An Ultrastructural Analysis of Spruce Budworm-Promoted Defoliation in Abies Balsamea
1989Balsam fir (Abies balsamea), a transcontinental gymnosperm, is of economic importance for lumber and wood pulp. Forest managers are continually faced with demands to increase wood yield. The problem is exacerbated in the case of balsam fir since spruce budworm periodically severely depletes the available wood inventory.

Ring-level models for predicting wood and fibre properties of Abies balsamea
Wood Science and Technology, 2014Wood and fibre properties such as wood density, microfibril angle, and modulus of elasticity are industrially relevant factors in determining the mechanical properties of wood. Radial ring-level predictive models of these properties were developed using balsam fir data from a long-term trial in New Brunswick (Canada), where precommercial thinning was ...

Developmental and seasonal patterns of mesophyll ultrastructure in Abies balsamea
Canadian Journal of Botany, 1975Changes in mesophyll ultrastructure with development and season are described for Abies balsamea. Cells mature sequentially during expansion of the needles. Most cells appear to be fully mature and actively photosynthesizing at the time of budbreak. Tannins appear early and accumulate throughout the growing season.

THE ESSENTIAL OIL OF ABIES BALSAMEA (L.) MILL.
Canadian Journal of Chemistry, 1953Foliage of Abies balsamea yielded 0.591% of an essential oil comprised of l-β-pinene, l-bornyl acetate, d-Δ3-carene, l-limonene, l-α-pinene, l-camphene, myrcene, santene, tricyclene, l-camphor, l-borneol, d-canadene, bisabolene, terpinolene, and a compound related to S-guiaiazulene.
