Download or read book Trease and Evans Pharmacognosy written by William Charles Evans and published by Elsevier Health Sciences. This book was released on 2009-05-27 with total page 3322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy. No other book provides such a wealth of detail. A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'. Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique. Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas. New chapter on 'Neuroceuticals'. Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation. Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'. More on the study of safety and efficacy of Chinese and Asian drugs. Quality control issues updated in line with latest guidelines (BP 2007).

Download or read book Biotechnology and Ecology of Pollen written by David L. Mulcahy and published by Springer. This book was released on 2011-11-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.

Download or read book Mites of Greenhouses written by Zhi-Qiang Zhang and published by CABI. This book was released on 2003-01-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mites are among the most important arthropods in greenhouses, both as pests causing economic injury to greenhouse crops, and as natural enemies used in the biological control of pest insects and other mites. Because of their minute size, mites are much less well known than insects. This book describes the biology, identification and control of such mites and the topics covered include an introduction to the Acari, illustrated keys to orders, families and selected species, the control of pest mites, and the role of beneficial mites in biological control. The book will be of interest to those working in entomology, crop protection and horticulture.

Download or read book Conservation and Utilization of Horticultural Genetic Resources written by P.E. Rajasekharan and published by Springer. This book was released on 2019-06-25 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.

Download or read book Tyrophagus Acari Astigmata Acaridae written by Qing-Hai Fan and published by Manaaki Whenua Press. This book was released on 2007 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Tyrophagus comprises a group of primarily fungivorous mites, including the mould mites, commonly found in stored food products and decaying organic matter. They are also associates of various insects, or inhabitants of vertebrate nests. They are the most abundant and economically important mites inhabiting stored food and products. Some Tyrophagus species are also facultatively phytophagous and can cause economic damage to plants, including both ornamental flowers and vegetables grown in greenhouses. Tyrophagus belongs to the supraorder Acariformes, order Astigmata, family Acaridae. Currently, it comprises about 35 species and is worldwide in distribution. In this contribution species of the genus Tyrophagus present in New Zealand are comprehensively revised, along with species found in Australia and other Oceanian countries. Ten species, including two new species, are described and illustrated from New Zealand. Identification keys to adult males and females are given, along with taxonomic references, hosts/habitats and distribution data of each species. This will help identification and facilitate requests for rapid quarantine decisions from trading partners."
