Weeds affect everyone in the world by reducing crop yield and crop quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health, preventing water flow, as plant parasites, etc. Weeds are common everywhere and cause many $ billions worth of crop losses annually, with the global cost of controlling weeds running into $ billions.The anatomy of plants is generally well understood, but the examples used for explanations in most books are often restricted to non-weed species. Weeds have many features that make them more competitive, for example enabling them to more quickly recover after herbicide treatment. Some of these adaptations include rhizomes, adapted roots, tubers and other special structures. Until now,no single book has concentrated on weeds’ anatomical features. A comprehensive understanding of these features is, however, often imperative to the successful implementation of many weed control measures.Beautifully and comprehensively illustrated, in full colour throughout, Weed Anatomy provides a comprehensive insight into the anatomy of the globally-important weeds of commercial significance. Commencing with a general overview of anatomy, the major part of the book then includes sections covering monocotyledons, dicotyledons, brackens and horsetails, with special reference to their anatomy. Ecological and evolutionary aspects of weeds are also covered and a number of less common weeds such as Adonis vernalis, Caucalis platycarpos and Scandix pecten-veneris are also included.The authors of this book, who have between them many years of experience studying weeds, have put together a true landmark publication, providing a huge wealth of commercially-important information. Weed scientists, plant anatomists and agricultural scientists, including personnel within the agrochemical and crop protection industry, will find a great deal of useful information withinthe book’s covers. All libraries in universities and research establishments where agricultural and biological sciences are studied and taught should have copies of this exceptional book on their shelves.

Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year.

Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes:

Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds

Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.

Combines new findings on morphological aspects, the latest data on gene function in grasses, and the interaction of grasses with their habitats45% of all arable land is covered by five grass crops: wheat, maize, rice, barley and sugar cane. This book demonstrates why crops and weeds are growing in characteristic environments today, and looks at how cropping practices may change in the future and how these changes will affect weed spectra. It explains the distribution of grasses and their role for mankind and summarizes our knowledge on grass genomes. Special emphasis is placed on the function of genes at defined developmental stages and in organs of grasses. The development of grasses is then described from the germination to fruit set with many unpublished examples.Grasses: Crops, Competitors and Ornamentals provides readers with a comparative description of selected grass organs (stem, root, leaf, inflorescence) and devotes several chapters to habitats of grasses and morphological characteristics that enable grasses to grow in special environments. In addition, some chapters deal with grasses as crops and weeds, and emphasis is placed on their adaptation to modern agriculture. Predicts how cropping practices may change in the future and how these changes will affect weed spectraDetails grasses as crops and weeds, emphasizing their adaptation to modern agricultureSummarizes our knowledge on grass genomesConnects classical morphology with the latest tools in molecular biology as well as ecological aspects determining the wide distribution of grass species todayGrasses: Crops, Competitors and Ornamentals will be of great interest to agricultural scientists who want to know more about crops and weeds, grassland specialists and breeders interested in special grass traits, and molecular biologists and ecologists who study the biology and habitat of grasses.

Comprehensive reference on the characteristics of rhizomes, stems growing roughly horizontally below ground level, important for perennial and hard-to-control weeds and for the propagation of some commercially important crops. Rhizomes describes and compares rhizomes, classifies them based on their features, and presents their ecological and commercial importance. The book is divided into seven parts. After a short introduction, Part I discusses the evolution of rhizomes and their function as organs. Part II provides an introduction into rhizomes of basal tracheophytes, formerly called pteridophytes, now referred to as Lycopodiopsida and Polypodiopsida or lycophytes and ferns. Part III covers monocot rhizomes with a focus on the high diversity of rhizomes found in monocots. Part IV focuses on dicot rhizomes and their morphological diversity. Part V explores the ecological and commercial importance of rhizomes, with special information on crops and weeds with rhizomes. Lastly, findings on rhizomes in different plant groups are compared, and conclusions on the development and diversification of rhizome characters are presented. Written by two highly qualified authors with significant research experience in the field, Rhizomes covers topics such as: Difficulty in making a clear distinction between rhizomes, runners, and stolons and inner cortex cells of rhizomes differing in sheath modifications Different types of species with stem-borne roots, including dicot representatives with roots arising from the hypocotyl and plants with roots at nodes, internodes, and buds Molecular genetics research analyzing molecular mechanisms and signaling processes leading to stolon and rhizome initiation and development Rhizome producing species forming either large colonies or genetically identical groups, with advantages and disadvantages of each With English literature on rhizomes being relatively sparse, Rhizomes is a unique and highly comprehensive reference on these types of stems, ideal for agronomists, botanists, horticulturists, breeders, ecologists, and weed scientists seeking to understand their important role in agriculture and food.
