Naturalized Offspring From An 85-Year-Old Chinese Chestnut (Castanea Mollissima) Planting: Stand Dynamics And Genetic Relationships, Amy Christel Miller
Open Access Theses
Chestnuts, members of the genus Castanea , family Fagaceae, are valuable worldwide, and all species have noteworthy ecological, economic, and cultural importance in their native ranges. Historically, American chestnut (Castanea dentata (Marshall) Borkh.) was an abundant tree species in eastern North America until its decimation in the early 20 th century by chestnut blight, caused by the fungus Cryphonectria parasitica . To regain the benefits of this prized species in North America, efforts are ongoing to produce and introduce blight-resistant hybrids of C. dentata and the blight-resistant Chinese chestnut ( C. mollissima Blume). It is important that the C. …
Evaluating The Current Status Of Chestnut-Present Forest Systems: Integrating Gigapan As A Tool For Site Assessment, Charles Taylor Brewer
Evaluating The Current Status Of Chestnut-Present Forest Systems: Integrating Gigapan As A Tool For Site Assessment, Charles Taylor Brewer
Theses, Dissertations and Capstones
The field of environmental science can directly benefit from a society driven by advances in technology. The loss of the American chestnut (Castanea denata) has had a significant negative environmental and economic impact throughout the Appalachian region. However, using an integrated approach utilizing recent advances in science and technology, we may be able to promote the re-introduction of a very similar species within this region. Using GigaPan as a tool for site assessment and data storage, and previous methods of biological field surveying within the critical detritus layer of the forest floor, we will assess the status of forest ecosystems …

Somatic Embryogenesis From Immature Cotyledons Of Some European Chestnut (Castanea Sativa Mill.) Cultivars, Beki̇r Şan, Mehmet Sezgi̇n, Hati̇ce Dumanoğlu, A. İlhami̇ Köksal
Turkish Journal of Agriculture and Forestry
In 4 European chestnut (Castanea sativa Mill.) cultivars ('Hacıibiş', 'Karamehmet', 'Osmanoğlu' and 'Sarıaşlama'), somatic embryogenesis from immature cotyledons of open-pollinated seeds collected 5, 6, 7, and 8 weeks after anthesis and cultured on Driver and Kuniyuki walnut (DKW) medium was determined in this study. The percentage of embryogenic cotyledons and the number of embryos per embryogenic cotyledon were recorded at the end of the second subculture. The results showed that the highest percentage of embryogenesis ranged from 40% to 70% and the number of embryos per embryogenic cotyledon varied from 4.04 to 7.70 among the cultivars. Cotyledons collected 5, 6, …
