Balsam poplars

Acetophenone. Acetophenone [98-86-2] (methyl phenyl ketone) is a colorless Hquid that forms laminar crystals at low temperature (mp 20°C). It has a characteristic sweet orange blossom odor, and is soluble in alcohols and ethers. It is found in nature in oil of casatoreum, obtained from beavers oil of labdanum, recovered from plants and in buds of balsam poplar. It can be prepared by the Friedel-Crafts reaction (qv) of acetyl chloride with benzene in the presence of aluminum chloride however, this route is of Htde commercial significance.

Female flowers of dioecious trees are better defended than males. RuflFed grouse, Bonasa umbellus, prefer male flowers of quaking aspen, Populus tremuloides, in winter, and leaves of male specimens in summer (Svoboda and Gullion 1972). Ruffed grouse also feed more on male trees of balsam poplar (Bryant etal, 1991).

Thick Forest ecosystems are found only along the valley s of large rivers, occupying well-drained places of terraces, slopes and low hills, lying at an altitude of 700-750 m. White spruce (Picea canadensis), balsam poplar, aspen, and in some places white birch, are trees common to these Forest ecosystems black spruce, fir and larch are found more rarely. The latter is attracted to swampy areas. On flat, ill-drained surfaces, forest ecosystems are replaced by vast areas of bog mosses and, in relief depressions, sedge-cotton grass bog. 

The genus Populus includes hardwood trees commonly referred to as poplars, cottonwoods, and aspen, which are found throughout North America, Europe, and northern Asia. They are particularly dominant in the boreal forest and in the parkland zones of Canada and the American midwest. Widespread North American species include P. balsamifera (balsam poplar), with a range from Western Alaska to northern Quebec and Newfoundland, and P. tremuloides (trembling or quaking aspen), which is found from Alaska to Mexico. Both are prominent species of the boreal forest of Canada. P. trichocarpa (black cottonwood) is found along the Pacific coast from California to Alaska. The range of P. tremula (European aspen)... 

No information on the safety of balsam poplar in pregnancy or lactation was identified in the scientific or traditional literature. Although this review did not identify any concerns for use while pregnant or nursing, safety has not been conclusively established.

This may range from less than 0.34 for balsam poplar (i.e., Populus balsamifera) up to about 0.88 for hve oak (i.e., Quercus virginiana). If the specific gravity of wood is known, based on oven-dry weight and volume at a specified moisture content, the specific gravity at any other moisture content between 0 and 30 wt.% can be calculated using the equation ... 

Common/vernacular names Poplar buds and balsam poplar buds. 

Populus tacamahacca (balsam poplar) is a tree often up to 33 m high, trunk about 3 m in diameter, with stout, erect branches. 

Populus candicans (true halm of Gilead) has been considered as a variety of the balsam poplar only the pistillate tree is known.
