Authors:
- Describes the potential relationships, where they may exist, for direct transfer between plants, plant communication and allelopathic interactions. Defines past and present terminology and the boundaries for plant-plant allelopathic interactions. Provides a general background for plant-plant allelopathic interactions
- Provides conceptual “black box” models for hydrophilic, hydrophobic and volatile allelopathic molecules. Describes how these molecules may be partitioned in laboratory bioassay systems.
- Describes the actual and conditional physicochemical properties (e.g., pKa, Log P, log D, molecular structure, Kd and Koc) of phenolic acids such as cinnamic and benzoic acids and how these properties may be related to the partitioning of phenolic acids in solution and in soil systems and to their effects on nutrient and water uptake and growth of sensitive seedlings (in this case cucumber seedlings)
- Describes the physicochemical (e.g., soil particle sorption) and/or biological processes (e.g., microbial utilization and root uptake) that occur in seedling-solution-culture systems and in seedling-microbe-soil-sand systems
- Provides quantitative data for hypothetical models on how phenolic acids may be partitioned and may effect sensitive seedlings
- Answers the following questions: Can the physicochemical properties of phenolic acids be used as tools to understand the complex behaviour and effects of phenolic acids? What insights do laboratory bioassay provide about the potential behaviour and effects of phenolic acids in field systems? What potential role may phenolic acids play in broadleaf-weed seedling emergence in wheat no-till cover crop systems?

About this book
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 volumewas 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? Whatpotential role may phenolic acids play in broadleaf-weed seedling emergence in wheat debris cover crop no-till systems?
