This book was released on 1981 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A disease of Jeffrey pines (Pinus jeffreyi Grev. and Balf.) at Lake Tahoe Basin, California, caused by Elytrodenna disease (Elytroderma deformans) was studied for 7 years after a severe outbreak of the fungus in 1971. Among 607 Jeffrey pines on six plots, about one-half were heavily infected and about one-half were moderately or lightly infected in 1971. No uninfected trees were observed. During the 7-year study, about one-half of the trees remained unchanged in vigor, disease intensity, or both, and about one-half decreased in vigor, became more heavily infected, or both. Of the original 607 trees studied, nearly one-third died before 1978. Average radial growth of surviving trees was less per year after the outbreak than before, and heavily infected trees were growing more slowly than lightly infected trees. Intensity of the disease, however, was not related to stand basal area.

Book excerpt: Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Download or read book Pine Wilt Disease and the Decline of Pine Forests written by Kazuyoshi Futai and published by Cambridge Scholars Publishing. This book was released on 2021-08-18 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: After devastating vast ranges of pine forests in Asian countries, Pine Wilt disease invaded European forests, becoming a worldwide threat. Originating in North America, the pathogen of this forest epidemic is a nematode, a long filamentous organism, only 1mm in length. Nematodes are carried from tree to tree by a long-horned beetle, where they lurk in its trachea and thereby spread the disease. The challenges raised for researchers to develop effective control methods were to discover how such tiny nematodes infect and kill large pine trees within a short period, and how the infection spreads repeatedly each year. Other key issues include how giant pine trees die within a short period of time due to infection by these small nematodes, how various organisms involved in this disease correlate to each other, how host trees differently respond to nematode invasion among pine species, and how environmental factors affect the progression and spread of the disease. This book is a record of the fantastic and ingenious research by many tenacious researchers who have worked to clarify these issues. Information on a wide range of fields, from molecular biology to microbiology, nematology, entomology, botany, and ecology, has been incorporated into pine wilt research. Therefore, this book will greatly stimulate the curiosity and research motivation of those interested in field biology and the conservation of the natural environment.
