This book was released on 2008-12-18 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of haploids is well known to geneticists and plant breeders. The discovery of anther-derived haploid Datura plants in 1964 initiated great excitement in the plant breeding and genetics communities as it offered shortcuts in producing highly desirable homozygous plants. Unfortunately, the expected revolution was slow to materialise due to problems in extending methods to other species, including genotypic dependence, recalcitrance, slow development of tissue culture technologies and a lack of knowledge of the underlying processes. Recent years have witnessed great strides in the research and application of haploids in higher plants. After a lull in activities, drivers for the resurgence have been: (1) development of effective tissue culture protocols, (2) identification of genes c- trolling embryogenesis, and (3) large scale and wide spread commercial up-take in plant breeding and plant biotechnology arenas. The first major international symposium on “Haploids in Higher Plants” took place in Guelph, Canada in 1974. At that time there was much excitement about the potential benefits, but in his opening address Sir Ralph Riley offered the following words of caution: “I believe that it is quite likely that haploid research will contr- ute cultivars to agriculture in several crops in the future. However, the more extreme claims of the enthusiasts for haploid breeding must be treated with proper caution. Plant breeding is subject from time to time to sweeping claims from ent- siastic proponents of new procedures.
Download or read book Systematic Pomology Vol 1 2 Set written by O.P. Pareek and published by Scientific Publishers. This book was released on 2017-01-01 with total page 953 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is aimed to be a treatise on the ‘Systematic Pomology’, the primary component of science of fruits, dealing with identification, nomenclature and classification of fruit species based on the descriptions of characteristics related to their morphological, genetical, physiological, biochemical, biotechnological and eco-attributes. Besides taxonomic narrative of each species under the respective orders and genera, considerable emphasis has been laid on cultivars. The treatment is based on the latest version of Nomenclature and Phylogenetic System of Classification (APG III). The book is richly illustrated with diagrams and colour plates and carries fairly exhaustive bibliography and glossary. Thus, the book is of high academic value for research workers/teachers, students and anyone interested in advanced fruit culture to provide insight in identifying and classifying fruit plants, providing standard nomenclature and terminology, in avoiding the confusion from synonymy and promoting correct labeling, to understand their genetic relations, in establishing or maintaining a garden, a germplasm block, a research orchard or even herbaria, in identification of new genotypes or cultivars for introduction and in deciding orchard management practices as well as methods of utilization, in using the correct related cultivars kept in a genetic resources repository for improvement considering the limits of hybridization, and in selecting genetic material for a breeding programme considering their taxonomic proximities and specific characters related to fruit bearing, regularity, nutritive and edible quality, resistance to biotic and abiotic stresses and plant stature and form.

Download or read book Guideline for Salinity Assessment Mitigation and Adaptation Using Nuclear and Related Techniques written by Mohammad Zaman and published by Springer. This book was released on 2018-11-28 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.
Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

Download or read book Cultural Techniques written by Bernhard Siegert and published by Fordham Univ Press. This book was released on 2015-05-01 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a crucial shift within posthumanistic media studies, Bernhard Siegert dissolves the concept of media into a network of operations that reproduce, displace, process, and reflect the distinctions fundamental for a given culture. Cultural Techniques aims to forget our traditional understanding of media so as to redefine the concept through something more fundamental than the empiricist study of a medium’s individual or collective uses or of its cultural semantics or aesthetics. Rather, Siegert seeks to relocate media and culture on a level where the distinctions between object and performance, matter and form, human and nonhuman, sign and channel, the symbolic and the real are still in the process of becoming. The result is to turn ontology into a domain of all that is meant in German by the word Kultur. Cultural techniques comprise not only self-referential symbolic practices like reading, writing, counting, or image-making. The analysis of artifacts as cultural techniques emphasizes their ontological status as “in-betweens,” shifting from firstorder to second-order techniques, from the technical to the artistic, from object to sign, from the natural to the cultural, from the operational to the representational. Cultural Techniques ranges from seafaring, drafting, and eating to the production of the sign-signaldistinction in old and new media, to the reproduction of anthropological difference, to the study of trompe-l’oeils, grids, registers, and doors. Throughout, Siegert addresses fundamental questions of how ontological distinctions can be replaced by chains of operations that process those alleged ontological distinctions within the ontic. Grounding posthumanist theory both historically and technically, this book opens up a crucial dialogue between new German media theory and American postcybernetic discourses.
