Inner Roots

The root system is a vital part of the plant and therefore understanding roots and their functioning is key to agricultural, plant and soil scientists. In Plant Roots Professor Peter Gregory brings together recent developments in techniques and an improved understanding of plant and soil interactions to present a comprehensive look at this important relationship, covering: Root response to, and modification of, soils Genetic control of roots’ responses to the environment Use of modern techniques in imaging, molecular biology and analytical chemistry Practical exploitation of root characters This book will be a vital tool for plant, crop, soil and agricultural scientists, plant physiologists, environmental scientists, ecologists and hydrologists. It will be a valuable addition to libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught.

The author considers neuroscience and psychobiology to identify analogies with the potential of musical expression to bring about therapeutic change, as observed during his work with children with autistic spectrum and pervasive developmental disorders.

Scientists, within a wide field, ranging from applied forestry and agriculture to physiology, ecology and the environmental sciences, are today more than ever involved in root and mycorrhizal research. New problem-oriented research fields have arisen such as the effects of fertilizers and pesticides, forest management and regeneration etc. At a time when root research is expanding into different areas, it is much more difficult for the root scientist to penetrate all the new information appearing in literature. The contributors of this volume are leading scientists from different fields of root research. The ISRR-symposium in Uppsala clearly demonstrated that there are new techniques in progress, in particular with regards to video recording of plant root systems and digital image processing. The main objectives of the symposium were (i) to provide a forum for communication between scientists from different disciplines working with root research problems, (ii) to contribute to an expansion of root studies into new areas, (iii) to use current estimates of root turnover for charting the upper and lower limit of below-ground production, and (iv) to spread knowledge of new findings and techniques of the importance of root research. This book is aimed at serving as a vehicle for improving the coherence of root research, for harmonizing methods and establishing overall objectives and gaps in the knowledge of rhizosphere dynamics.

This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. 'The Supporting Roots - Structure and Function,' 20-24 July 1998, Bordeaux, France. The meeting was held under the auspices ofIUFRO WPS 2. 01. 13 'Root Physiology and Symbiosis,' and its aim was to bring together scientific researchers, foresters and arboriculturalists, to discuss current problems in structural root research and disseminate knowledge to an audience from a wide disciplinary background. For the first time in an international conference, emphasis was placed on presenting recent reseach in the field of tree anchorage mechanics and root biomechanics. The way in which tree stability can be affected by root system symmetry and architecture was addressed, as well as how movement during wind sway can influence the development and shape of woody roots. The role of different nursery and planting techniques was discussed, in relation to effects on root system form and development. Root response to different environmental stresses, including water, temperature, nutrient and mechanical stress was addressed in detail. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere. One of the conference highlights was the presentation of new methods in root research, by a series of workshops held at LRBB-INRA, Pierroton, on the northern border of the Gascony forest.

Roots represent half of the plant body – and arguably the more interesting half. Despite its obvious importance for the whole plant, until recently our knowledge of the root apparatus was very limited, mostly due to the inadequacy of the techniques available. Recent advances in the visualization and measurement of roots have resulted in significant progress in our understanding of root architecture, growth and behaviour. In this book international experts highlight the most advanced techniques, both lab and field methods, and discuss them in detail. Measuring Roots combines academic and practical aspects of this topic, making it a universal handbook for all researchers and others interested in root-measuring methods.

Use the veterinarian’s #1 reference on general pathology and the pathology of organ systems! Pathologic Basis of Veterinary Disease, 7th Edition helps you understand and diagnose diseases of domestic animals by using the latest scientific and medical research. Focusing on dogs, cats horses, cattle, sheep, goats, and pigs, this reference describes and vividly illustrates and explores the pathogeneses of animal diseases, how cells and tissues respond to injury, and the morphology (lesions) of this injury. New to this edition is basic coverage of tumor, inflammatory, and microbial cytology. Edited by veterinary pathologist James F. Zachary and a team of expert veterinary pathologists, this book includes access to an enhanced eBook with every new print purchase, featuring a fully searchable version of the entire text, an image collection, and much more – and available on a variety of devices. Clear, up-to-date illustrations and explanations of the macroscopic (gross) and microscopic lesions resulting from diseases occurring in domestic animals Complete coverage of both general pathology and the pathology of organ systems that includes the latest research, practice, and diagnostic information on disease mechanisms, pathogenesis, and lesions. Clear explanations of disease mechanisms that describe cell, tissue, and organ system responses to injury and infection. Easy-to-follow organization for each systemic disease chapter including a brief review of the study of diseases that occur in specific tissues, organs, and organ systems, with basic principles related to anatomy, structure, and function, followed by congenital and functional abnormalities and discussions of infectious disease responses, helping students apply principles to veterinary practice. More than 2,100 full-color illustrations featuring color photographs, schematics, flow charts, and diagrammatic representations of disease processes as well as summary tables and boxes, making it easier to understand difficult concepts. Content on cellular and organ system pathology updated throughout the book, with expanded coverage of genetics and disease. Key Readings Index in each chapter with page numbers for key topics. Essential Concept boxes in each General Pathology chapter break down complicated topics that are critical to understanding lesions and pathogeneses. More than 20 recognized experts deliver the most relevant information for the practitioner, student, or individual preparing for the American College of Veterinary Pathologists’ board examination. An enhanced eBook is included with new print purchase, featuring the complete, fully searchable text plus an image collection; the text, tables, and boxes linked to the website that are cited throughout the book; ten new appendices that focus on veterinary diagnostic pathology, postmortem examination, interpretation of lesions, and more; plus an established appendix of photographic techniques used in veterinary diagnostic pathology.
