Download or read book Betula written by Carl T. Bertelsen and published by . This book was released on 2020-04-24 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Betula, generally known as birch, belongs to the family Betulaceae. There are about 83 recognized species of Betula, all of which are essential ecological components of northern temperate and boreal woodlands in many parts of the world. The species of this genus have a good tolerance to freezing temperature and water deficit, as well as high sensitivity to UV-B exposure. The chemical composition of Betula pubescens Ehrh. and Betula pendula Roth. buds is assessed, providing data on their biological activities. Betula species show antiarthritic, anticancer, antidiabetic, anti-inflammatory, antimicrobial, antioxidant, antiviral, gastroprotective, hepatoprotective and immunomodulatory activities, and the authors propose that it is important to consider the biopharmaceutical properties of the secondary metabolites for further development.
Download or read book The Soil Seed Banks of North West Europe written by Ken Thompson and published by Cambridge University Press. This book was released on 1997 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buried viable seed banks are a fundamental aspect of seed plant biology. They play a key role in the conservation and restoration of plant communities and the response of plants to changing land use and climate. There is almost no area of plant ecology in which seed banks are not implicated. Despite several recent reviews of the ecology of seed banks, there has previously been no single source of data on seed persistence in individual species. This volume, which compiles the available data from the nineteenth century up to the end of 1993, provides this source for the 1189 members of the northwest European flora. The text describes the criteria for inclusion of data and discusses seed classification systems, the relative representation of different habitats, methods and taxa, and challenges for future research. Includes PC disc with database in searchable format.

Download or read book Protocols for Micropropagation of Woody Trees and Fruits written by S.Mohan Jain and published by Springer Science & Business Media. This book was released on 2007-09-18 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micropropagation has become a reliable and routine approach for large-scale rapid plant multiplication, which is based on plant cell, tissue and organ culture on well defined tissue culture media under aseptic conditions. A lot of research efforts are being made to develop and refine micropropagation methods and culture media for large-scale plant multiplication of several number of plant species. However, many forest and fruit tree species still remain recalcitrant to in vitro culture and require highly specific culture conditions for plant growth and development. The recent challenges on plant cell cycle regulation and the presented potential molecular mechanisms of recalcitrance are providing excellent background for understanding on totipotency and what is more development of micropropagation protocols. For large-scale in vitro plant production the important attributes are the quality, cost effectiveness, maintenance of genetic fidelity, and long-term storage. The need for appropriate in vitro plant regeneration methods for woody plants, including both forest and fruit trees, is still overwhelming in order to overcome problems facing micropropagation such as somaclonal variation, recalcitrant rooting, hyperhydricity, polyphenols, loss of material during hardening and quality of plant material. Moreover, micropropagation may be utilized, in basic research, in production of virus-free planting material, cryopreservation of endangered and elite woody species, applications in tree breeding and reforestation.

Download or read book Biological Fixation of Nitrogen for Ecology and Sustainable Agriculture written by Andrzej Legocki and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF) - the conversion of molecular nitrogen into ammonia - is one of the most important reactions in ecology and agriculture. It is performed exclusively by microbes (prokaryotes) that live in symbiosis with plants. This book summarizes the latest research on this reaction, the participating microbes and the genetics of how their relevant genes could be transferred into the plants. In the light of a more sustainable and less ecologically damaging agriculture, this is becoming an increasingly pressing issue.
Download or read book Trees Beyond the Wood colour written by Ian D. Rotherham and published by Lulu.com. This book was released on 2013-07-05 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trees Beyond the Wood was written for a conference organised to celebrate twenty years of work since the first major conference on the theme of ancient trees and woodlands held in Sheffield, UK. It was held almost ten years after the landmark 2003 Working and Walking in the Footsteps of Ghosts event which started to raise issues and challenge assumptions about what is 'ancient' or 'natural' and what is meant by the terms 'wood' or 'woodland'. Since then on-going work in a range of disciplines across ecology, biology, landscape history, archaeology, forestry and nature conservation has continued the process of research and evaluation across the subject area. The collection of papers by contributors from across Europe reflects this broad range of interests and disciplines.

Download or read book Environmental Standards written by Christian Streffer and published by Springer Science & Business Media. This book was released on 2003-08-04 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of the world population - nearly six-fold over the last hundred years - combined with the rising number of technical installations especially in the industrialized countries has lead to ever tighter and more strained living spaces on our planet. Because ofthe inevitable processes oflife, man was at first an exploiter rather than a careful preserver of the environment. Environmental awareness with the intention to conserve the environment has grown only in the last few decades. Environmental standards have been defined and limit values have been set largely guided, however, by scientific and medical data on single exposures, while public opinion, on the other hand, now increasingly calls for astronger consideration of the more complex situations following combined exposures. Furthermore, it turned out that environmental standards, while necessarily based on scientific data, must also take into account ethical, legal, economic, and sociological aspects. A task of such complexity can only be dealt with appropriately in the framework of an inter disciplinary group.
