Book Description
This book presents principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.

Book Description
Ecologically Based Weed Management Protect crop yields and strengthen ecosystems with this essential guide Research into weed management is an increasingly critical component of both environmental stewardship and food production. The potential cost of weed propagation can be measured in crop yield reductions, under-nourished populations, stymied economies, and more. The propagation of herbicide-resistant weed populations means that purely chemical weed management is no longer viable; food production can now be secured only with an ecological approach to weed control. Ecologically Based Weed Management details such approaches and their potential to manage weeds across a range of agricultural and environmental contexts. It emphasizes the deployment of ecological principles to prevent weed infestations, reduce crop losses, and strengthen ecosystems. In a time when growing population and changing climates are placing enormous pressure on global food production, this approach to weed management has never been more vital. Ecologically Based Weed Management readers will also find: A global team of expert contributors to a multidisciplinary approach Detailed discussion of topics like herbicide limitation, integrated weed management, and more Insights pertinent to agriculture, academia, government, industry, and more Ecologically Based Weed Management is ideal for researchers in agriculture chemistry, weed science, agronomy, ecology, and related fields, as well as for regulators and advanced students.

Book Description
Buried viable seed banks are a fundamental aspect of seed plant biology. They play a key role in the conservation and restoration of plant communities and the response of plants to changing land use and climate. There is almost no area of plant ecology in which seed banks are not implicated. Despite several recent reviews of the ecology of seed banks, there has previously been no single source of data on seed persistence in individual species. This volume, which compiles the available data from the nineteenth century up to the end of 1993, provides this source for the 1189 members of the northwest European flora. The text describes the criteria for inclusion of data and discusses seed classification systems, the relative representation of different habitats, methods and taxa, and challenges for future research. Includes PC disc with database in searchable format.

Book Description
Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.

Book Description
This 1974 book was made available as a second edition in 1979. It provides an understanding of the ways in which the various physiological processes are integrated to produce the responses shown by whole plants growing in the variable environment in the field, whilst stressing the quantitative aspects of these relationships. This was the first general text to attempt such a treatment, thereby digesting much material that had been found only in research papers or detailed monographs and complementing the reductionist approach of most standard texts of plant physiology. Most of the subject matter concerns agricultural systems, but many of the concepts and approaches are applicable to more complex natural ecosystems. Emphasis is placed on integrating knowledge from many sources and on trying to assess quantitatively the importance of each component. The result is a comprehensive account making the book a valuable background for all interested in the study of plants in the field.

Book Description
Light and Plant Development presents the Proceedings of the 22nd University of Nottingham Easter School in Agricultural Science. It discusses the spectral sensitivity of inhibition of flowering by light. It addresses the action spectrum for leaf enlargement and stem growth inhibition. Some of the topics covered in the book are the nature of the blue light photoreceptor in higher plants and fungi; re-examination of photochemical properties and absorption characteristics of phytochrome using high-molecular-weight preparations; and intermediates in the photoconversion of phytochrome. The high irradiance reaction is fully covered. The physiological evidence and localised responses, intracellular localisation and action of phytochrome are discussed in detail. The text describes in depth the immunological visualisation of phytochrome. The fractionation procedures and terminology are presented completely. A chapter is devoted to the photocontrol of enzyme levels. Another section focuses on the ribosomal RNA synthesis in developing leaves. The book can provide useful information to botanists, chemists, students, and researchers.
