Download or read book Frost Survival of Plants written by Akira Sakai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperature represents, together with drought and salt stress, one of the most important environmental constraints limiting the pro ductivity and the distribution of plants on the Earth. Winter survival, in particular, is a highly complex phenomenon, with regards to both stress factors and stress responses. The danger from winter cold is the result not only of its primary effect, i. e. the formation of ice in plant tissues; additional threats are presented by the freezing of water in and on the ground and by the load and duration ofthe snow cover. In recent years, a number of books and reviews on the subject of chilling and frost resistance in plants have appeared: all of these publications, however, concentrate principally on the mechanisms of injury and resistance to freezing at the cellular or molecular level. We are convinced that analysis of the ultrastructural and biochemical alterations in the cell and particularly in the plasma membrane during freezing is the key to understanding the limits of frost resistance and the mechanisms of cold acclimation. This is undoubtedly the immediate task facing those of us engaged in resistance research. It is nevertheless our opinion that, in addition to understanding the basic physiological events, we should be careful not to overlook the importance of the comparative aspects of the freezing processes, the components of stress avoidance and tolerance and the specific levels of resistance.

Download or read book Frost and Pollen written by Helen Hajnoczky and published by . This book was released on 2021-10-05 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flower and flour. Coral and choral. Lashes and luscious. Frost & Pollen is a poetry collection in two acts: "Bloom & Martyr" is a sensuous walk through a menacing garden of flowers and desire, while "Foliage" retells the Arthurian legend of Sir Gawain and the Green Knight from the point of view of the Green Knight, the mysterious figure who teases and torments Gawain. By turns earthy and lush, and punctuated by dark and unsettling undercurrents, these poems converge into an engaging yet evasive feminine exploration of nature and sexuality.

Download or read book Allergenic Pollen written by Mikhail Sofiev and published by Springer Science & Business Media. This book was released on 2012-09-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to summarize all aspects of allergenic pollen: production, atmospheric distribution, and health impacts, as well as the means of monitoring and forecasting these phenomena. Based on a four-year effort by a large group of leading European scientists, this book highlights the new developments in research on allergenic pollen, including the modelling prospects and effects of climate change. The multidisciplinary team of authors offers insights into the latest technology of detection of pollen and its allergenic properties, forecasting methods, and the influence of allergenic pollen on the population. The comprehensive coverage in this book makes it an indispensible volume for anyone dealing with allergenic pollen worldwide. Readers involved in environmental health, aerobiology, medicine, and plant science will find this book of interest.

Download or read book Conifer Cold Hardiness written by F.J. Bigras and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Cold Hardiness provides an up-to-date synthesis by leading scientists in the study of the major physiological and environmental factors regulating cold hardiness of conifer tree species. This state-of-the-art reference comprehensively explains current understanding of conifer cold hardiness ranging from the gene to the globe and from the highly applied to the very basic. Topics addressed encompass cold hardiness from the perspectives of ecology, ecophysiology, acclimation and deacclimation, seedling production and reforestation, the impacts of biotic and abiotic factors, and methods for studying and analyzing cold hardiness. The content is relevant to geneticists, ecologists, stress physiologists, environmental and global change scientists, pathologists, advanced nursery and silvicultural practitioners, and graduate students involved in plant biology, plant physiology, horticulture and forestry with an interest in cold hardiness.

Download or read book Forest Genetics and Sustainability written by Csaba Mátyás and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 4th International Consultation on Forest Genetics and Tree Building, held in 1998 in Beijing, China, leading scientists were invited to review past achievements, to redefine the role of forest genetics and breeding in contemporary forestry, and to set priorities for future research and development. On the basis of the invited presentations, the volume summarizes the state of knowledge in various fields, such as the impact of forest management and of changing environmental conditions on genetic resources, and the value of genetic markers as indicators for adaptational potential, as well as the tasks of conservation. Detailed reports from the different continents provide a comprehensive diagnosis of the global situation of forest genetics and tree breeding research. The book offers not only an overview of contemporary trends and expected future developments, but also identifies current main problems in funding and cooperation. It may prove therefore useful not only for scientists, university lecturers and advanced students in the field of forestry, ecology and conservation biology, but also for decision makers and managers in companies and conservation organizations.
