VALORIZATION OF CHESTNUT BY-PRODUCT FOR GASTROINTESTINAL HEALTH
… phytochemical characterization of several chestnut by-products (bud, spiny bur, wood, pericarp and episperm), together with the exploitation of scavenging capacity, anti-inflammatory properties in intestinal (CaCo-2) and gastric (AGS and GES-1) cells, and anti-H. pylori activities. …

Small stem assay for chestnut blight resistance in segregating half-sib and full-sib families of F2 and backcross hybrid chestnut trees
Chestnut breeders routinely screen hybrid chestnut seedling progeny for resistance to chestnut blight in an orchard setting – a process that takes five to seven years. A novel technique that allows for screening in the first and second growing season is known as a small stem assay. We screened 110 …

Roles of tannase and hydrolyzable tannins in chestnut blight
… parasitica</u>(Murr.) Barr), the causal agent of chestnut blight, was able to grow in total aqueous and tannin extracts from blight-susceptible American chestnut as well as in blight-resistant Chinese chestnut bark extracts, from winter and summer bark. Differences in the amount of conidial …

An oral history of the American chestnut in southern Appalachia
… during the years preceding and following the chestnut blight pandemic. The project examined experiences from an environmental history perspective, addressing the economic and cultural significance of chestnut pre and post blight, and attitudes and feelings concerning American chestnut …

The separation of the insoluble non-tannin constituents from chestnut extract
In the preparation of tannin extract from chestnut wood chips there is present in the extract, along with the tannin, certain insoluble non-tannin constituents. If allowed to remain in the extract, these materials make the tanning solution unsuitable for use in the manufacture of leather. To …

Contemporary Sanctuary: constructing an addition to Chestnut Methodist Church, Newport News, Virginia
The project offers a design for an addition to a Methodist Church in Newport News, Virginia. The proposal includes a new sanctuary, kitchen, meeting room, and entrance. Axonometric inquiries, detailed sections, and explorations with 3-d models document the structural configuration and the inner …

Biology of virulent and hypovirulent Endothia parasitica on American chestnut (Castanea dentata)
… and intact trees of large, surviving American chestnut indicated that some have heritable blight resistance. Some degree of resistance in American chestnut possibly would assist spread of hypovirulence (H) factors. The pathogenicity of the H isolate but not the V (virulent) isolate appeared to …

Accelerated, graft-based germplasm conservation of American chestnut (Castanea dentata) in the South
… method for conservation of rare American chestnut germplasm. Particularly when in situ conditions prevent trees from reaching sexual maturity, graft-propagation allows release from shade conditions and disease pressure to promote flowering. Collection of pollen from containerized grafted …

Tree-ring studies of Chestnut (Castanea sativa) in the Belasitsa Mountain in southern Bulgaria
… research project on ecology of the European chestnut (Castanea sativa) forest which took place in Belasitsa Mountain in southern Bulgaria. I worked with experts at the Icelandic Forest Research in Mógilsá, who work in cooperation with the Forest Research Institute in Sofia. The project is …

Population biology of Cryphonectria parasitica infected with Cryphonectria hypovirus 1 on American chestnut trees
In the early 1900's the American chestnut (Castanea dentata (Marsh.) Borkh.) was nearly destroyed by the introduction of the orange-pigmented, chestnut blight fungus (Cryphonectria parasitica (Murr.) Barr). Chestnut blight is less severe in Europe, where hypovirulent (= reduced virulence) strains …

Water Chestnut: Field Observations, Competition, and Seed Germination and Viability in Lake Ontario Coastal Wetlands
Water chestnut (Trapa natans L.) has recently invaded an increasing number of sites in New York State, particularly Lake Ontario coastal wetlands. It can severely inhibit ecosystem functioning and can be costly to control. To understand this exotic invasive plant more thoroughly, field observations …

Phomopsis castanea infection levels in chestnut from the North and South Islands of New Zealand
… (Sacc.) causes serious losses to the New Zealand chestnut industry. In anticipation of the likely increased importance of the chestnut industry in New Zealand, a study was undertaken as part of the ultimate goal of eliminating or minimising this storage rot problem. This study focused on …

Evaluating the Adaptive Genomic Landscape of Remnant and Backcross American Chestnut Populations to Inform Germplasm Conservation
The American chestnut tree (Castanea dentata) is a deciduous tree that largely exists in the eastern United States along the Appalachian Mountain range. Approximately 100 years ago, a fungal pathogen (Cryphonectria parasitica) decimated chestnut populations, resulting in the loss of billions of …

Early Successional Processes of Experimentally-Reclaimed Mine Sites in Eastern Ohio and the Restoration of American Chestnut
… due to an introduced pathogen, was the American chestnut (<i>Castanea dentata</i>). The original extent of the American chestnut and the Appalachian coal fields are nearly concurrent, possibly making these experimentally reclaimed sites ideal for restoration plantings of disease-resistant …

Spread of White Hypovirulent Strains of Cryphonectria Parasitica Among American Chestnut Trees at the Lesesne State Forest
… main stems of three 16-year-old grafted American chestnut trees at the Lesesne State Forest were sampled for Cryphonectria parasitica. Cankers were sampled in 1996 and 1997 at various distances from the main stem zone on the grafts (ground to 183 cm) that was inoculated in 1982 and 1983 with a …

The seasonal occurrence, soil distribution and flight characteristics of Curculio sayi (Coleoptera: Curculionidae) in mid-Missouri
Chestnut trees were once a dominant sight across the deciduous forest of the eastern and central United States, but following a devastating blight in the early 1900's much of the native range for this tree species has been lost. As interest in the restoration of the American chestnut tree …
