Exclusive accumulation of Z-isomers of monolignols and their glucosides in bark of Fagus grandifolia

Phytochemistry, 1988
In addition to Z-coniferyl and Z-sinapyl alcohols, bark extracts of Fagus grandifolia also contain significant amounts of the glucosides, Z-coniferin, Z-isoconiferin (previously called faguside) and Z-syringin. The corresponding E-isomers of these glucosides do not accumulate to a detectable level.

SPATIAL DISTRIBUTION AND DEVELOPMENT OF ROOT SPROUTS IN FAGUS GRANDIFOLIA (FAGACEAE)

American Journal of Botany, 1986
Root sprouts around 31 Fagus grandifolia parent trees, some declining due to beech bark disease, were studied to describe the pattern of sprout distribution, the ecological importance of this pattern, and the relationship between sprout patterns and parent vigor.

Resistance to water flow in Fagus grandifolia leaves

Canadian Journal of Botany, 1977
The tempo of water efflux from single Fagus grandifolia leaves has been measured. The resistance to pressure-driven water efflux has been measured for normal leaves, Rs, and for leaves in which extracellular mesophyll spaces are infiltrated with water, Rs*. The ratio Rs*/Rs is about 0.4.

DEMOGRAPHY OF A SHADE-TOLERANT TREE (FAGUS GRANDIFOLIA) IN A HURRICANE-DISTURBED FOREST

Ecology, 1998
We examined the demographic responses of Fagus grandifolia to Hurricane Kate (1985) in an old-growth Southern mixed-hardwood forest in northern Florida. Matrix population models were used to contrast pre- and post-hurricane population trends (1978- 1992) with predictions of four hypotheses of the persistence of this shade-tolerant species in hurricane ...

Species Distribution Modeling of American Beech (Fagus Grandifolia) Distribution in Southwest Ohio

International Journal of Applied Geospatial Research, 2017
The ability to predict American beech distribution (Fagus grandifolia Ehrh.) from environmental data was tested by using a geographic information system (GIS) in tandem with species distribution models (SDMs). The study was conducted in Butler and Preble counties in Ohio, USA.

Codominance of Acer saccharum and Fagus grandifolia: the role of Fagus root sprouts along a slope gradient in an old-growth forest

Journal of Plant Research, 2010
We studied how the unusual capacity of mature Fagus grandifolia to form clumps of clonal stems from root sprouts can contribute to its frequent codominance with Acer saccharum in southern Quebec, Canada. In an old-growth forest, the degree of dominance by the two species shifted along topographic gradients spanning a few hundreds of meters, with Fagus ...

Suppression and Release During Canopy Recruitment in Fagus grandifolia

Bulletin of the Torrey Botanical Club, 1990

Utilizing pigment-producing fungi to add commercial value to American beech (Fagus grandifolia)

Applied Microbiology and Biotechnology, 2011
American beech (Fagus grandifolia) is an abundant, underutilized tree in certain areas of North America, and methods to increase its market value are of considerable interest. This research utilized pigment-producing fungi to induce color in American beech to potentially establish its use as a decorative wood. Wood samples were inoculated with Trametes

The Fagus grandifolia-Acer saccharum-Podophyllum peltatum Association in Northeastern Ohio

Botanical Gazette, 1977
Ten near-climax stands in northeastern Ohio, dominated by Fagus grandifolia and Acer saccharum, are quantitatively described. Acer seedlings are much more abundant than Fagus seedlings; the two codominants are equally well represented in the larger size classes.

Functional ecology of growth in seedlings versus root sprouts of Fagus grandifolia Ehrh.

Trees - Structure and Function, 2012
We assessed growth differences and the foliar traits underpinning production in paired samples of juvenile American beech (Fagus grandifolia Ehrh.) that originated from seed versus root sprouts. Root sprouts had significantly greater relative extension growth rate and slightly greater leaf mass per unit area compared to seed-derived individuals, but ...
