Описание: Grasses are the foremost plant family of prairies, savannas, barrens, many agricultural landscapes, lawns, and successional habitats throughout Wisconsin, yet they are notoriously difficult to identify. This field guide to 232 species of Wisconsin grasses includes more than 1,100 illustrations. Setting a new standard as the first new, illustrated midwestern grass identification manual to appear since the 1960s, it provides up-to-date, comprehensive information for naturalists, gardeners, landscapers, nursery horticulturalists, community restoration professionals, agronomists and biologists, and any outdoors lover. The book includes: - species descriptions and distribution maps for all 232 species - more than 700 color photographs accompanying species descriptions - drawings of most species - chapters on grass morphology and grasses in natural communities - keys to all species, including an illustrated key to genera - a glossary of grass terminology.

Описание:
The grass family is one of the largest and most diverse families in the plant kingdom and is of great economic value. Grasses provide human beings and domestic animals with the main necessities of life, add diversity to the landscape and stability to the ground surface, and also provide ornamental and amenity value. The present handbook is a pictorial resource guide to the identification of different common grasses in their early growth stage. In this book, 100 of the most common grasses (palatable and unpalatable) growing in the grasslands have been characterized on the basis of the vegetative characters of the seedling. A key to the identification of the grasses at their seedling stages is provided to help easily identify the grasses at their early stage of development.
Many of the grasses described in the book are cosmopolitan, and many grow worldwide. Terms used to describe a grass seedling are used with help of photographs. Different diagnostic features of the seedling--such as growth habits, types of vernation, nodes, internodes, leaf laminas, leaf tips, leaf sheaths, ligules, auricles, and collars--have been used for their identification. The descriptions and photographs enable users to successfully and easily identify these species in a field environment.
The book has been divided into two main sections. The first section covers the characteristic features of the caryopses. It includes light and scanning electron microscopic features and a diagnostic key to the identification of the species. The second section deals with grass seedling morphology and provides a key to the identification of the species on the basis of early vegetative features. Each of the sections includes an introduction, materials and methods, and results, supplemented with microphotographs representing the features of identification.
This handbook is the first of its kind to include so many grass species that can be authentically identified with the help of pictorial diagnostic features of the seedlings and caryopses. The identifying features are solely on the basis of morphological, micromorphological, and morphometric characters.
This handbook will be an important reference book of value to students in basic grass taxonomy or ecology classes as well as to academicians, researchers, pasture management practitioners, as well as professionals working in grassland restoration.

Описание: This 1990 text brings together a detailed review by acknowledged authorities of grass reproductive biology. Essential to contemporary awareness of grasses is an understanding of their role in sustaining ecologically fragile environments, and the relative importance of annual and perennial reproduction is examined here.
Описание: This book analyzes the impacts of current and possible future GM crop applications and shows that these technologies can contribute substantially to sustainable agricultural development and food security.

Описание: Originally published in 1957, this book was created in response to serious losses in brassica crop production caused by viral diseases. The text was the product of experiments and observations carried out under a wide range of conditions in various parts of Britain. Information is provided on the causes of disease and the reaction of plants to infection.

Описание: Over many millennia, farmers across the world have domesticated literally thousands of species and developed tens of thousands of varieties of these plants. Despite the astonishing agricultural diversity that existed long ago, the world's current food base has narrowed to a dangerous level. By studying the long and dynamic history of farming in the ancient past, archaeology can play a part in helping ensure the stability of the human food supply by identifying once-important crops and showing where and how such crops were grown in the past. Thanks to this work, extinct crops might even be redomesticated from their wild progenitors. New Lives for Ancient and Extinct Crops profiles nine plant species that were important contributors to human diets and had medicinal uses in antiquity: maygrass, chenopod, marshelder, agave, little barley, chia, arrowroot, little millet, and bitter vetch. Each chapter is written by a well-known scholar, who illustrates the global value of the ancient crop record to inform the present. From eastern and western North America, Mesoamerica, South America, western Asia, and south-central Asia, the contributors provide examples of the unexpected wealth of information available in the archaeological record about ancient and extinct crops.
