متن کاملForest regeneration composition and development in upland, mixed-oak forests.
Advance regeneration in 52 mature mixed-oak stands was analyzed and described. Red maple (Acer rubrum L.) was the most abundant species in the study area. Among oak (Quercus) species, northern red oak (Q. rubra L.) was the most abundant within the Allegheny Plateau physiographic province, whereas chestnut oak (Q. montana L.) was the most abundant within the Ridge and Valley physiographic provin...

The three major dimeric proanthocyanidins present are epicatechin(4f,>8)-catechin, catechin-(4a>8)-catechin and the 3-gallate ester of epicatechin-( 4~>8)-catech...
متن کاملSolute accumulation of chestnut oak and dogwood leaves in response to throughfall manipulation of an upland oak forest.
To determine the biochemical basis of osmotic adjustment, seasonal and treatment differences in foliar water- soluble organic solutes and inorganic ions were investigated for two hardwood species that exhibited osmotic adjustment in a Throughfall Displacement Experiment at the Walker Branch Watershed near Oak Ridge, Tennessee. Leaf samples of overstory and understory chestnut oak (Quercus prinu...
