THE ESSENTIAL OIL OF PICEA MARIANA (MILL.) B.S.P.
Canadian Journal of Research, 1950 The essential oil of Picea mariana has been prepared and its major constituents separated by fractional distillation. Evidence for the presence of 15 constituents has been obtained, and santene, tricyclene, l-α-pinene, l-camphene, l-β-pinene, myrcene, d- Δ3-carene, dl-limonene, terpinolene, dl-camphor, l-borneol, and l-bornyl acetate have been ...

Environmental Pollution, 2001
Mining operations in areas of the boreal forest have caused salinity issues to be a major concern for reclamation. One of the factors determining successful reclamation is the ability of species to self-propagate. The effects of salinity on the seedling emergence and early growth of three boreal forest conifers: Picea mariana, Picea glauca, and Pinus ...

Understorey vegetation change in a Picea mariana chronosequence
Vegetatio, 1988Eighteen black spruce (Picea mariana) stands, representing postfire ages of 26 to 120 yr, were surveyed for understorey vegetation and site/microsite characteristics at two spatial scales. This enabled comparison of within- versus among-stand compositional variation.

Growth Response of Picea mariana Seedlings to Competition for Radiation
Scandinavian Journal of Forest Research, 2000The growth response of 4-year-old black spruce seedlings (Picea mariana (Mill.) B.S.P.) to reduced radiation availability (DIFN) caused by herbaceous and woody competitors was investigated on a clay and on a loam site on a research plot in Ontario, Canada.

Differences in crown characteristics between black (Picea mariana) and white spruce (Picea glauca)
Canadian Journal of Forest Research, 2012Black spruce ( Picea mariana (Mill.) Britton, Sterns & Poggenb.) and white spruce ( Picea glauca (Moench) Voss) are phylogenetically proximal species that differ in productivity. Crown characteristics of these two species have not been extensively studied, in spite of the importance of these two species to the Canadian boreal forest and the ...

Transgenic Black Spruce (Picea mariana)
2000Black spruce (Picea mariana) is one of about 40 species of the genus Picea A. Dietr. (family Pinaceae) scattered throughout the cooler parts of the north temperate zone and higher elevations in the south (Farrar 1995). Alone or with white spruce and tamarack [Larix laricina (Du Roi) K. Koch], black spruce forms the northern boundary of tree-form growth.

A NEW GENUS OF PHACIDIACEAE ON PICEA MARIANA
Canadian Journal of Botany, 1963A new phacidiaceous genus, Micraspis, is erected to accommodate a single species, M. acicola, on Picea mariana (Mill.) B.S.P. from Northern Ontario. Its probable conidial state is described as Periperidium acicola gen. et sp. nov.

The Ureolytic Microflora in a Black Spruce (Picea mariana Mill.) Humus
Soil Science Society of America Journal, 1967Abstract The total and the ureolytic microflora in black spruce humus from an untreated plot and from a plot fertilized with 450 kg urea‐N per ha (400 lb N per acre) 2 years before sampling was studied using incubation tests. Following the addition of 3,500 ppm of urea‐N in the laboratory the total numbers of bacteria and fungi ...

Remote sensing of biophysical variables in boreal stands of Picea mariana
1995 International Geoscience and Remote Sensing Symposium, IGARSS '95. Quantitative Remote Sensing for Science and Applications, 2002Using two hybrid radiative transfer models to represent conifer canopies and stands the authors develop and evaluate algorithms to infer several important structural parameters of stands of black spruce (Picea mariana), the most common boreal forest dominant.
