        Parasitic Plants in African Agriculture

        by Lytton John Musselman, Jonne Rodenburg

        Parasitic Plants in African Agriculture brings together for the first time in a single volume, the ecology, biology, damage, and control of all groups of African parasitic plants including both the relatively few parasites introduced to the continent as well as those native parasites that have spread from within Africa. The book covers the well-known witchweeds and broomrapes but also groups and species that have received less attention including mistletoes, dodders, rice vampire weed, and other species posing threats. The book distinguishes between stem and root parasitic weeds and between holoparasites and (facultative or obligate) hemiparasites. Based on their research and experience collectively spanning six decades, the authors provide an authoritative and state-of-the-art overview of the distribution, biology and impact of these highly specialized weeds and include recommendations for their management. Since parasitic plants in African agriculture primarily affect smallholder farmers, these weeds are explicitly discussed within a context of resource limitations and global changes. Readers are informed on all parasitic plant species relevant to African agriculture and the impact these plants have on crop production and livelihoods of smallholders in a changing world. Current and future management strategies are outlined in terms of their principles and effectiveness as well as their feasibility and affordability for farmers, all of which determine farmer adoption. The final chapter synthesises some of the relevant findings and statistics regarding parasitic weed distribution and their host crops and discusses implications in terms of future crop protection concerns in African agricultural systems. Key features: · Authoritative text based on extensive field and laboratory work. · First comprehensive state-of-the-art overview of parasitic plants and their management in Africa. · Highly illustrated with photos, graphs and species distribution maps. · Reviews previous basic and applied work, with relevance to smallholder farming systems. This book will be a valuable reference for students, researchers, extension workers, development officers, national agriculture researchers, plant pathologists, food security specialists, weed scientists, agronomists and botanists.

        Lexicon of Medicinal Plants

        by Prof. Dr. Dietrich Frohne (†), in collaboration with Prof. Dr. Birgit Classen

        Indian mulberry, St. John’s wort, Hawaiian baby woodrose – whether disputed wonder drug, traditional medicinal plant or unknown exotic plant – the Lexicon of Medicinal Plants can always be relied upon. The lexical and classic knowledge about the individual medicinal plants – such as family, origin, use, effect and constituents – garnered over decades and peppered with particular anecdotes on the herbal drugs, can be regarded as unique and largely timeless. At the repeated request of readers, this reference work has therefore been reissued in book form, with its contents largely unchanged but with misprints corrected and its layout modernised. A wealth of experience that even in the fast-moving digital world preserves traditional knowledge.

        Medicinal Plants used in Traditional Persian Medicine

        by Hartwig Schulz, Seyed Ahmad Emami, Farsad Nadjafi

        Medicinal plants and the natural products within them, still remain the starting point for breakthroughs in the development of safe, pharmacologically active synthetic molecules for use in a wide variety of clinical situations. Traditional Persian Medicine (TPM) is one of the most ancient medical doctrines, and is well-documented in terms of information about diseases, diagnoses and treatments, especially by the application of medicinal plants. TPM has been used for centuries worldwide, and many of these methods are still used in Iran today. This book introduces the basics of TPM, and describes the key medicinal plants which are used for the treatment of different diseases. It also creates possible new targets for research activities in drug discovery of natural products. The book is richly illustrated with coloured figures of historic drawings from old Persian pharmacopoeia and photos of plants in their natural habitats. References to Ayurvedic, Traditional Chinese Medicine and to monastic medicine in Europe are also made. Knowledge about medicinal plants used in TPM still exists in Iran, however, there is a risk that the detailed expertise provided by the older generation will be lost in the near future. It is therefore important that this cultural heritage of humanity is properly preserved. This book provides a valuable, evidence-based resource on TPM for researchers, practitioners and students in medicinal plants, ethnobotany and herbal medicine.

        Pest Management in Cotton

        A Global Perspective

        by Graham A. Matthews, Thomas A. Miller, Zeeshan Ahmed

        This book presents a global overview of the background to, and the current state of, crop protection and pest management in cotton crops. Cotton is one of the most economically important crops in the world and has been grown for centuries but maintaining high yields of good quality requires sophisticated approaches to pest management. The introduction and use of pesticides over the decades significantly increased cotton yields but lead to many adverse environmental impacts. Over time, new and alternative insecticides were developed but overuse has enabled pests to develop significant resistance. The development of genetically modified cotton varieties with toxins derived from Bacillus thuringiensis enabled much improved control of lepidopteran larvae, including bollworms, but as the toxins had no effect on sucking pests, farmers had no choice but to continue using insecticides. Also, some of the new cotton varieties developed in recent times have not adapted to different climatic conditions and the quality of cotton fibre declined as a result. This book shows the need for more research to select cotton varieties with high quality fibres suitable for different cotton growing areas and to develop integrated pest management strategies to minimise the use of pesticides. It also demonstrates the need for an inter-disciplinary approach bringing together plant breeders, entomologists, plant pathologists, agronomists and agricultural engineers to achieve high yields of high quality cotton. In the future, farmers will need to adopt new technology to determine when and how pesticides are used in conjunction with cultural and biological control strategies. · Emphasises the importance of research on growing cotton in a world experiencing climate change · Demonstrates how crucial crop protection is in achieving high yields of high quality cotton · Shows how new technology will bring major changes in how cotton is grown in the future

        Plant Development, Second Edition

        by William G. Hopkins; Series Editor: William G. Hopkins

        A plant grows by taking in carbon dioxide from the air and water, as well as nutrients from the soil. Using light energy from the sun, a plant turns these simple materials into more complex organic molecules that add to its increasing size. Plant Development, Second Edition explores this natural process, from the plant as a single cell to a mature organism, giving students a reference point for their understanding of the complex changes in both form and function of a plant's development. This is a valuable tool for students and teachers of plant biology.

        Genetics of Salt Tolerance in Plants

        a Central Dogma Perspective and Strategies for Enhancement

        by Showkat Ahmad Ganie, Shabir Hussain Wani

        Gene expression in cells follows a prescribed pathway that conforms to the Central Dogma; where the genetic information stored in DNA is transcribed into RNA and then expressed into proteins, which influences most plant traits. Plant salt tolerance research is directed towards identifying nucleotide variants that could contribute to tolerant phenotypes. This book comprehensively presents the current state of knowledge on plant salt tolerance through meticulous analysis of the processes operating across the Central Dogma. It provides a detailed account of modulation of gene expression through genome editing systems to achieve crop improvement against salt stress. It also provides state-of-the-art information on advances in breeding technologies of genome selection and accelerated de novo domestication for rapidly improving the salt tolerance of plants for global food security. This book: 1.Provides a comprehensive coverage of plant salt tolerance mechanisms. 2.Spotlights various factors functioning along the Central Dogma pathway and their regulation in response to salinity. 3.Examines how these factors function to protect the plants from high salinity. 4.Highlights advances in cutting-edge breeding technologies for improving salt tolerance. The book will be of particular value to students and researchers of plant genetics, molecular biology and physiology and those with an interest in salinity and salt tolerance.

        Biotechnology and Plant Disease Management

        by Edited by Zamir K Punja, Solke De Boer, Helene I Sanfacon

        As agricultural production increases to meet the demands of a growing world population, so has the pace of biotechnology research to combat plant disease. Diseases can be caused by a variety of complex plant pathogens including fungi, bacteria, viruses and nematodes, and their management requires the use of techniques in transgenic technology, biochemistry and genetics. While texts exist on specific pathogens or management practices, a comprehensive review is needed of recent developments in modern techniques and the understanding of how pathogens cause disease. This collection of studies discusses the key approaches to managing each group of pathogens within the context of recent developments in biotechnology. Broad themes include microbe-plant interactions, molecular diagnostics of plant pathogens and enhancing the resistance of plants.

        Ornamental Bedding Plants

        by Allan M Armitage

        Traditionally, bedding plants are those plants used to provide colour in summer garden beds. Although some writers include any herbaceous plant started under controlled environmental conditions and sold for outdoor use, embracing a number of fruit and vegetable crops, in this book ornamental bedding plants include tender herbaceous ornamental annuals and biennials only. As with other titles in this series, the aim of this book is to present scientific principles that underlie production practices. The author discusses traditional and plug methods of production, the latter having revolutionized mass market production during the last decade. The principles of propagation and growing on, including the role of nutrition and media, temperature, light, supplemental carbon dioxide and growth regulators, are described. Aspects of postproduction, diseases and pests, and mechanization, are also considered. There is also an appendix providing production guidelines for 15 major bedding plant species, including begonia, impatiens, petunia, marigolds and pansies. Written by one of America’s foremost horticultural scientists and writers, the book is invaluable for plant producers or growers, as well as for students of ornamental or amenity horticulture.

        Plant Nutrition, Second Edition

        by Alex C. Wiedenhoeft, Series Editor: William G. Hopkins

        The mineral nutrients of plants play key roles in plant growth and development, forming the underpinnings of the past, present, and future of agriculture. Plants with insufficient nutrients exhibit symptoms of sickness that can be confused with infectious plant diseases. The nutrients needed by plants are taken from the soil by the roots, and in many plants, the roots also form associations with other organisms that help them more efficiently colonize the soil or provide nutrients to the plant. All facets of plant nutrition, from the effect of nutrients on the plant to the role of plants in the global cycling of nutrients, impact the ways in which humans use and depend on plants for most aspects of our existence. Plant Nutrition, Second Edition addresses the basic chemistry, biology, physiology, and ecology of plant nutrition and shows how these topics relate to humans on a personal, social, and global scale.
