Book excerpt: Excerpt from The Search in Foreign Countries for Blight-Resistant Chestnuts and Related Tree Crops In July, 1924, P. H. Dorsett, long connected with the work of the Office of Foreign Plant Introduction, left for northeastern China, accompanied by his son, James H. Dorsett. The explorations made by Dorsett and Dorsett have resulted in procuring additional chestnut material, including nuts from wild and cultivated trees from the regions north and northeast of Peking. In view of the great interest in substitutes for our native chestnut that may prove able to withstand the blight and be utilized in breed ing work, looking to the supplying of timber, tannin, and food, it has seemed desirable to bring together certain data bearing on the species already introduced or that may be introduced. This seems particularly necessary, inasmuch as there is considerable confusion and some misunderstanding as to the real merits of the introductions heretofore made.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Chestnut, a Bibliography: A Bibliography of References to Castanea Dentata and Other Chestnut Species, and on Chestnut Blight and Its Causal Pathogen of the Fungal Genus Endothia or Cryphonectria In working with a bibliography over a period of 12 years, trends in research and publication become apparent. Jean Q. Wade carefully tabulated the entries by time period and subject, providing the data for a few observations here: The interest in fungi, particularly pathogens, was strong in the 19th Century and continues today. In contrast, nucleic acid and other biochemical studies are relatively recent. In the early blight period, there was a major effort to understand the life cycle, spread, and pathogenic action of the blight fungus. There has been only one attempt to summarize the history of the blight and research related to the blight, Fifty years of Chestnut Blight in America (beattie and Diller, They observed that, All of the cooperative work (among Federal and State scientists) slowed and almost came to a close in 1914 and 1915 when chestnut blight appropriations were greatly reduced. The organizations were broken up and the men scattered to do other work. The attempt to understand and stop the blight was meager. From 1906 to 1910, (while the disease was spreading north, south, and west from New York City), only a few hundred dollars a years of Federal money were In that year (1911) Congress appropriated In 1912 an appropriation of was made, and this was repeated the following the Pennsylvania legislature appropriated for the 1913-14 biennium (beattie and Diller.

This book was released on 2018-05-03 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chestnut Blight in the Southern Appalachians The chestnut blight is caused by a fungus introduced into this country on nursery stock from Asia. The organism attacks the bark Of the chestnut and forms cankers. These ultimately girdle and kill the parts affected, the dead foliage remaining persistent. A county by county survey begun in 1924 and still in progress has discovered infections at the southern limit Of commercial chestnut. Westward the spread Of the disease has been less rapid than south ward. It is believed that by 1930 more than half, and by 1935 nine tenths, Of the counties in the southern Appalachians will have reached the stage at which more than 80 per cent Of their trees will be infected. NO practical control is known, but if salvaged before deterioration sets in the lumber from blight-killed trees is equal to that cut from live trees. Great need exists for increased cutting and use Of chest nut, so that this timber may be utilized and other species conserved.

Download or read book Old Southern Apples written by Creighton Lee Calhoun and published by Chelsea Green Publishing. This book was released on 2011-01-20 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book that became an instant classic when it first appeared in 1995, Old Southern Apples is an indispensable reference for fruit lovers everywhere, especially those who live in the southern United States. Out of print for several years, this newly revised and expanded edition now features descriptions of some 1,800 apple varieties that either originated in the South or were widely grown there before 1928. Author Lee Calhoun was one of the foremost figures in apple conservation in America. This masterwork reflects his knowledge and personal experience over more than thirty years, as he sought out and grew hundreds of classic apples, including both legendary varieties (like Nickajack and Magnum Bonum) and little-known ones (like Buff and Cullasaga). Representing our common orchard heritage, many of these apples are today at risk of disappearing from our national table. Illustrated with more than 120 color images of classic apples from the National Agricultural Library’s collection of watercolor paintings, Old Southern Apples is a fascinating and beautiful reference and gift book. In addition to A-to-Z descriptions of apple varieties, both extant and extinct, Calhoun provides a brief history of apple culture in the South, and includes practical information on growing apples and on their traditional uses.

Download or read book American Chestnut written by Susan Freinkel and published by Univ of California Press. This book was released on 2009-04 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In prose as strong and quietly beautiful as the American chestnut itself, Susan Freinkel profiles the silent catastrophe of a near-extinction and the impassioned struggle to bring a species back from the brink. Freinkel is a rare hybrid: equally fluid and in command as a science writer and a chronicler of historical events, and graced with the poise and skill to seamlessly graft these talents together. A perfect book."—Mary Roach, author of Stiff and Spook "A spellbinding, heart wrenching, and uplifting account of the American chestnut that asks the vastly important question: Have we learned enough, and do we care enough, to begin healing some of the wounds we've inflicted on the natural world?"—Scott Weidensaul, author of Return to Wild America and Mountains of the Heart "This is a beautifully written account of the passing of one of the botanical wonders of the North American landscape, the American chestnut tree, which was nearly extirpated by a plague that entered the ecosystem and swept these great trees away. Freinkel, a gifted writer whose research is impeccable and whose reporting is topnotch, tells of the impassioned work of scientists over the past century and up to today, trying to bring the American chestnut back from the brink of extinction. Only a person in love with trees could have written this lovely book."—Richard Preston, author of The Hot Zone and The Wild Trees "Graceful, provocative, and inspiring. Thoreau would be proud."—Alan Burdick, author of Out of Eden, a 2005 National Book Award finalist "In this beautifully written volume, Susan Freinkel ably describes the marriage of science and passion that is being brought to bear to save this majestic American tree from extinction. The people whose ancestors lived among chestnut trees and their places come alive for the reader, as does the appearance and spread of the blight and the heroes who are struggling with it today. The book concludes with a tantalizing vision of chestnuts in the forests again—a thought of making the world right where it has gone wrong."—Peter H. Raven, Director of the Missouri Botanical Garden
Download or read book Forest Health and Biotechnology written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-04-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.
