Hydrocyanic Acid Potential of Black Cherry Leaves
Black cherry (Prunus serotina L.) leaves have been known to be a source of hydrocyanic acid poisoning of cattle since the late 1800 "s. Results of early studies indicated that the black cherry was one of the most toxic of the cyanogenetic plants. An early idea which has persisted to the present has …

Genetic Engineering of Black Cherry (Prunus serotina) for Reproductive Sterility and Insect Pest Resistance
<p>Black cherry (Prunus serotina Ehrh.) is one of the most valuable hardwoods for high- end cabinetry, furniture, architectural millwork, paneling, and veneer. However, the damage caused by cambial-mining insect pests triggers gummosis in black cherry, a non-specific defense response in which …

Effect of Ozone on CO2 Assimilation and PSII Function in Plants with Contrasting Pollutant Sensitivities
… of plants, tobacco (Nicotiana tabacum L.) and black cherry (Prunus serotina) were studied. Gas exchange analysis and chlorophyll fluorometry were utilized to characterize physiological function. Two tobacco cultivars, Bel-B and Bel-W3, tolerant and sensitive to ozone, respectively, were grown …

Effects of Alternative Silvicultural Treatments on Regeneration in the Southern Appalachians
… to analyze five species groups: oak, maple, black cherry-yellow-poplar, miscellaneous, and midstory. Response variables included importance value, average height, and density compared within species group and among treatments. Differences between sprout and seedling origin regeneration were …

Herbicide Hardwood Crop Trees Release in Central West Virginia
… American beech on each plot. Crop trees, mostly black cherry (Prunus serotina Ehrh.) were chosen on a 0.025 acre subplot established at each plot center. All beech two inches and larger on the 0.1 acre plots and competing trees touching crop trees were treated in June 1998. The treatments were …

White-tailed deer density and habitat relationships
… and fruits (30%) such as acorns, apples, and black cherry. No consistent effect of deer density on forage use in meadows was observed on the CRC. Meadow utilization decreased as the growing season progressed. Meadows were utilized more at the edge than 200 m from the edge (P = 0.06). No …

Characteristics Of Rest Sites Used By Raccoons (procyon Lotor) In Richmond, Kentucky
… tree cavities. The most commonly used tree was black cherry (Prunus serotina). Raccoons significantly chose the largest trees available (mean DBH 44.1 cm, t = 3.44, P < 0.05). Most ground rest sites were associated with abandoned groundhog (Marmota monax) burrows and located in vegetated edges …

Characterizing the Respiration of Stems and Roots of Three Hardwood Tree Species in the Great Smoky Mountains
… of stems and roots of overstory and understory black cherry (<i>Prunus serotina</i> Ehrh., BC), red maple (<i>Acer rubrum</i> L., RM) and northern red oak (<i>Quercus rubra</i> L., RO) trees were monitored over two growing seasons at two contrasting sites in the Great Smoky Mountains to …

Deposition and Fate of Atmospheric Mercury in Forested Landscapes of the Adirondack Park, NY
… needles and the highest concentrations found in black cherry (Prunus serotina). Latitude and longitude were negatively correlated with Hg concentrations in foliage and humus layer soils, while elevation was positively correlated with Hg concentrations in foliage and humus layer soils. Elemental …

Seasonal movements, habitat selection, and food habits of black bears (Ursus americanus) in Shenandoah National Park, Virginia
… movements, food habits, and habitat selection of black bears (<i>Ursus americanus</i>) in Shenandoah National Park, Virginia were studied from May 1982 to April 1985. A total of 47 collared bears, including 25 adult females, 17 adult males, and 5 subadult males < 3.5 years old, was located 3973 …
