Allelopathy is the study of the chemical interactions of plants. This concept has been known since antiquity, and first appears unambiguously in written form in about 350 B.C. in the works of Theophrastus. This book provides a detailed account of the concept of allelopathy as it has occured through the course of botanical literature from the earliest recorded writings to the modern era. In the ancient world, the negative and positive interaction of plants was expressed within the framework of antipathy and sympathy of things. As such, antipathy and sympathy were more widely understood than generally appreciated, and indeed were assimilated in aspects of culture outside of botany and agriculture. This book firstly addresses the question of what is allelopathy, as allelopathy is one of these unfortunate terms in ecology that has no unified definition. The book then examines the major episodes in the history of allelopathy: the writings from classical Greece and Rome; mediaeval Arabic, Indian and Chinese work; the advent of printing and promulgation of information in the 16th and 17th centuries; the 18th century and the theory of root excretion; the 19th century and the influence of A.P. de Candolle; the early 20th century and the work of Pickering and the USDA Bureau of Soils; and the years leading to the current era. The work draws extensively on original sources, and consequently many of the assertions published in relation to the background of allelopathy, are shown to be incorrect, or at best very inadequate. There is a great deal of information presented, in a consolidated or accessible form, for the first time. The book endeavours to set the history of allelopathy within both a scientific and sociological context.

In the first volume the author suggested that we could improve our understanding of plant-plant allelopathic interactions in the field by making laboratory bioassays more holistic. Reflections after the volume was published lead the author to conclude that a more detailed analysis of the factors making up laboratory bioassays was needed in the hope that such an analysis would provide clearer and more useful directions on how to design more holistic or more relevant laboratory bioassay systems. The more holistic being a theoretical goal and the more relevant being a more pragmatic goal. This volume has been written specifically for researchers and their graduate students who are interested in studying plant-plant allelopathic interactions. The author hopes that this retrospective and at times critical analysis of laboratory bioassays will provide a foundation for better and more field-relevant laboratory designs in the future. This volume has 7 chapters describing: 1. background for designing plant-plant allelopathic laboratory bioassays, 2. the fundamentals of laboratory bioassays, 3. the issues and challenges associated with designing more relevant laboratory bioassays, 4. a set of hypothetical standard screening laboratory bioassays, 5. the known effects of putative allelopathic compounds such as phenolic acids, the physicochemical and biotic factors that modify their effects, and their modes of action, 6. a set of standard hypothetical cause and effect laboratory bioassays, and 7. the differences between field systems and laboratory bioassay systems, ways to minimize the impacts of atypical factors in laboratory bioassays, and future directions.

This volume continues the retrospective analyses of Volumes I and II, but goes beyond that in an attempt to understand how phenolic acids are partitioned in seedling-solution and seedling-microbe-soil-sand culture systems and how phenolic acid effects on seedlings may be related to the actual and/or conditional physicochemical properties (e.g., solubility, hydrophobicity, pKa, molecular structure and soil sorption/desorption) of simple phenolic acids. Specifically, it explores the quantitative partitioning (i.e., source-sink relationships) of benzoic and cinnamic acids in cucumber seedling-solution and cucumber seedling-microbe-soil-sand systems and how that partitioning may influence phenolic acid effects on cucumber seedlings. Regressions, correlations and conceptual and hypothetical models are used to achieve these objectives. Cucumber seedlings are used as a surrogate for phenolic acid sensitive herbaceous dicotyledonous weed seedlings. This volume was written specifically for researchers and their students interested in understanding how a range of simple phenolic acids and potentially other putative allelopathic compounds released from living plants and their litter and residues may modify soil chemistry, soil and rhizosphere microbial biology, seedling physiology and seedling growth. In addition, this volume describes the potential relationships, where they may exist, for direct transfer of organic compounds between plants, plant communication and plant-plant allelopathic interactions and addresses the following questions: Can physicochemical properties of phenolic acids be used as tools to help understand the complex behavior of phenolic acids and the ultimate effects of phenolic acids on sensitive seedlings? What insights do laboratory bioassays and the conceptual and hypothetical models of laboratory systems provide us concerning the potential behavior and effects of phenolic acids in field systems? What potential role may phenolic acids play in broadleaf-weed seedling emergence in wheat debris cover crop no-till systems?

In an effort to implement conservation measures farmers have used a variety of production methods including reduced or zero tillage. With the implementation of these methods there has been an increase in the use of small grain and legume cover crops and their residues. One benefit of these production methods has been early season weed control. Presently the most promising cover crops and their residues for annual broadleaf weed control in temperate regions of the world are the small grains such as wheat and rye. The literature suggests that a variety of mechanisms are involved in regulating weed seedling emergence, among them the allelopathic effects of phenolic acids. This book addresses the following questions: How likely are the necessary phenolic acid concentrations and environmental conditions present in wheat no-till cropping systems for inhibition of annual broadleaf weed seedling emergence? and Do phenolic acids have a dominant role in regulating annual broadleaf weed seedling emergence or are phenolic acids just one component of a larger promoter/modifier/inhibitor complex in wheat no-till cropping systems? The book has four chapters covering: 1. allelopathic plant-plant interactions, 2. laboratory experiments, 3. field and associated laboratory experiments, and 4. conclusions and suggested future research. There are several things that are unique about this book: a. The format is that of a research paper published in scientific journals. b. It differs from the journal format in that logic, reasons, and justifications for various procedures are provided. c. The Scientific Method and its approach to research are emphasized. For example, if-then hypotheses and cons and pros are provided so that readers can draw their own conclusions. and d. Although a broad range of literature is included, this book is a retrospective analysis of some 20 plus years of research on plant-plant allelopathic interactions at North Carolina State University.

Allelopathy in Sustainable Agriculture and Forestry Zeng, Ren Sen; Mallik, Azim U.; Luo, Shi Ming (Eds.) Simply put, allelopathy refers to an ecological phenomenon of plant-plant interference through release of organic chemicals (allelochemicals) in the environment. These chemicals can be directly and continuously released by the donor plants in their immediate environment as water leachates volatiles in the air or root exudates in soil - or they can be the microbial degradation products of plant residues. Allelochemicals may interfere with survival and growth of neighboring or succeeding plants, and may also discourage insects and pathogens. Black walnut, eucalyptus, sunflower, sorghum, sesame and alfalfa are common examples of plants with allelopathic properties. Likewise, staple crops such as rice, wheat, barley and sorghum also exhibit allelopathic characteristics. Knowledge of this form of plant interference on other plants and on disease causing organisms has been used in agriculture since prehistoric time. By manipulating cropping pattern and sequence through mixed cropping or crop rotation, farmers have been able to maintain sustained productivity. However, use of numerous agrochemicals - including a wide range of herbicides, pesticides, fertilizers and genetically modified high yielding crops - has become the characteristic feature of modern industrial agriculture. Not only is the sustainability of crop yield called into question in this form of agriculture, but the extensive long-term and often irreversible environmental degradation including ground water contamination and food safety associated with industrial agriculture are now serious concerns worldwide. This book reports on the latest advances in allelopathy through the contributions of leading scientists in the field. The book addresses the history of allelopathy, the science of allelochemicals, and the application of allelopathy in agriculture and forestry. An emphasis on both methodology and application makes Allelopathy a truly practical reference for scientists, researchers and students of plant science, agriculture, forestry, terrestrial ecology and environmental science.
