INFLUENCES OF ESTABLISHED TREES ON MYCORRHIZAS, NUTRITION, AND GROWTH OF QUERCUS RUBRA SEEDLINGS

Ecological Monographs, 2002
Established plants may facilitate the regeneration of closely related seedlings if they increase populations of mutualistic symbionts that would otherwise be limiting. In this study we examined the influence of ectomycorrhizal and vesicular-arbuscular mycor- rhizal (VAM) trees on Quercus rubra seedlings to determine how trees influence mycorrhizal ...

Phenolics of Quercus rubra wood

Phytochemistry, 1971
Abstract Sixteen phenolics are positively identified in oak wood; seven had not been reported in oaks. Several additional phenolics are tentatively identified. Bark is briefly investigated. Lyoniside is shown to be lyoniresinol 2a- O -xyloside.

Rapid temperature acclimation of leaf respiration rates in Quercus alba and Quercus rubra

Tree Physiology, 2003
We conducted controlled (chamber) and natural (field) environment experiments on the acclimation of respiration in Quercus alba L. and Quercus rubra L. Three-year-old Louisiana, Indiana and Wisconsin populations of Q. alba were placed in growth chambers and exposed to alternating 5-week periods of cool (20 degrees C mean) and warm (26 degrees C mean ...

ACROPETAL LEAF DIFFERENTIATION IN QUERCUS RUBRA (FAGACEAE)

American Journal of Botany, 1991
Northern red oak ( Quercus rubra L.) leaves were shown to mature progressively from base to tip of the lamina based on studies of growth rates, anatomical differentiation, and 14 C‐transport. Lamina expansion in both length and width ceased in the basal

Formation of tyloses in felled Quercus rubra L.

Wood Science and Technology, 1975
Tyloses form in red oak (Quercus rubra L.) sapwood in a period of hours if the wood is cut during the active growth season and stored in green condition in the laboratory. If the wood is cut during dormancy and stored in green condition, tyloses form in a period of months. Electron microscopic examination reveals that the wall of a tylosis forms from a
