Download or read book Conifers of the World written by James E. Eckenwalder and published by Timber Press. This book was released on 2009-11-14 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.
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 Yew written by Fred Hageneder and published by Reaktion Books. This book was released on 2023-04-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and richly illustrated history, Yew will appeal to botanists and other readers interested in the history and symbolism of the natural world, now in paperback. The yew is the oldest and most common tree in the world, but it is a plant of puzzling contradictions: it is a conifer with juicy scarlet berries, but no cones; deer can feast on its poisonous foliage, but it is lethal to farm animals, and it thrives where other plants cannot because of its extraordinarily low rate of photosynthesis. Exploring this paradoxical plant in Yew, Fred Hageneder surveys its position in religious and cultural history, its role in the creation of the British Empire, and its place in modern medicine. Hageneder explains the way the yew is able to renew itself from the inside by producing interior roots and how early humans, fascinated with its regenerative powers, began to associate the tree with concepts of life and death, the afterlife, and eternity. As such, it can be found at the sacred sites of Native Americans, Buddhists, and Shinto shrines in Japan, and it has become a living symbol of the resurrection for the Christian faith. He describes how churchyards saved many yews during the Middle Ages when the trees were used for the mass production of the longbow, which laid the foundation for the British Empire. Finally, he discusses the latest scientific discoveries about the yew, including its use in cancer treatments.

Book excerpt: This edited book cover over 200 mushrooms with detailed profiles of all the species. Each profile includes information on macro-morphology, molecular characterization, application and a color photograph of the same. Gujarat mushrooms gives a complete idea of mushrooms found in Gujarat, there morphological identification, molecular barcoding and documented applications. Data presented on mushrooms spans collections of three consecutive years. The collected mushrooms were identified morphologically as well as at the molecular level using ITS as a marker. 942 specimens covering 316 species were submitted to BOLD. Of these the macrofungal diversity covered around 200 species. Some of the collected mushrooms were not only edible but were found to have nutraceutical as well as industrial value. Although the mushrooms collected are from Gujarat region only they are reported from different areas around the globe. Hence the proposed book will be useful not only regionally but across countries as well. Mushrooom is a macro fungus with a distinct fruiting body. Wild mushrooms have a significant biological and economic impact. The texture and pleasant flavor of certain mushrooms make them a delicacy for mankind. Mushrooms have a very high medicinal value as well with several reports of anticancer properties of mushroom extracts. This book is a useful read for researchers and academicians interested in mushrooms.

Download or read book Navelbine and Taxot re written by Muriel Le Roux and published by Elsevier. This book was released on 2016-11-26 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the many forms of cancer treatment, chemotherapy remains an important part of the arsenal in which Navelbine and Taxotere play a major role.These medicines result from molecules discovered by French researchers of the Institut de Chimie des Substances Naturelles (ICSN) of the CNRS, directed by Pierre Potier. By recounting this history, the authors of this book attempt to illustrate how the work of themselves and others, united in a community, has helped obtain these results. After having explained the strategy of the French policy makers to promote the French chemistry of natural substances, the authors explore how the academic efforts in this field have evolved, and the alignment between science and its applications has become increasingly present. The contributions of the CNRS to the industry, and vice versa, offer an alternative image of public research relationships and industrial research, where CNRS researchers are able to extend the limits of freedom and creativity. It is to account for this complexity that the authors here have chosen to write this history together, which is in a sense exemplary.Due to an association between history and chemistry, this book explains these discoveries by placing them in their specific politic, economic and scientific contexts. - Provides an overview of how the French research system facilitated the discovery of the two molecules, Navelbine and Taxotere, and their anticancer activity - Based on a collaboration between a chemist and an historian of science, technology and innovation - Offers a unique perspective, bringing together the specific knowledge and skills of chemistry and history - Embeds chemistry in the general history thereby opening a window on science in action

Download or read book Toxicology and Human Environments written by Ernest Hodgson and published by Academic Press. This book was released on 2012-09-28 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental toxicology is generally held to be the study of the potential of constituents of outdoor environments to impact either human health or the biological structure of the ecosystems involved. This volume is a first attempt to integrate toxicological studies of all of the many human environments, both indoor and outdoor, and their complex interrelationships. Included are considerations of natural environments, the agroecosystem, occupational, urban and domestic environments as well as the environment associated with Superfund sites and military deployments. The primary emphasis is on public health, including the potential health effects of toxicants found in different environments, the bioprocessing of such toxicants in humans and surrogate animals and the principles of risk analysis. Approaches the toxicology of human environments in a new and unique way, stressing the complex interrelationships of all human environments and the implication for human and environmental health Each chapter is written by an acknowledged expert and is addressed to those interested in the broader implications of the environmental modifications that are always associated with the activities of humans living and working in them

Download or read book The Physical Geography of Northern Eurasia written by Maria Shahgedanova and published by . This book was released on 2003 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third volume in The Oxford Regional Environments series. The series volumes are devoted to major regions of the world, each presenting a detailed and up-to-date body of scientific knowledge concerning a particular region. For most topics on the physical geography of Northern Eurasia abundant literature now exists. Most of it, however, is in Russian and other East European languages and this has significantly limited the number of potential readers. This volume seeks to familiarize, at an international level, those with an interest in this area with the most significant achievements in classical and current geographical research. The Physical Geography of Northern Eurasia covers most of the territory of the former USSR. The first section discusses the individual compenents of the physical environment. These chapters cut across regional boundaries and treate the area discussed as a whole. A regional analysis follows mainly in the context of geographical zonation, though a number of specific regions are given individual treatment. The concluding chapters discuss the effects of anthropogenic activities on the physical environment. The approach is an integrative one, tying together various aspects of the physical environments with the environmental implications of human activites. Every component of the environment is treated as a step in the development of the multi-faceted landscapes which in turn provide possibilities and limitations for cultural and economic usage.
