Water Relations of Plants

 

Academic Press, 1983.

ISBNs 9780124250406

Colección: ScienceDirect

Resumen (en inglés): Water Relations of Plants attempts to explain the importance of water through a description of the factors that control the plant water balance and how they affect the physiological processes that determine the quantity and quality of growth.
Organized into 13 chapters, this book first discusses the functions and properties of water and the plant cell water relations. Subsequent chapters focus on measurement and control of soil water, as well as growth and functions of root. This book also looks into the water absorption, the ascent of sap, the transpiration, and the water stress and its effects on plant processes and growth.
This book will be useful for students, teachers, and investigators in both basic and applied plant science, as well as for botanists, agronomists, foresters, horticulturists, soil scientists, and even laymen with an interest in plant water relations.

Wheat Structure

Biochemistry and Functionality

 

Woodhead Publishing, 1996.

ISBNs 9781855737976

Colección: ScienceDirect

Resumen (en inglés): Understanding the structural, compositional and physicochemical properties of the wheat used in bread, biscuits, pasta and other consumer products is important. This book brings together international experts to provide an overview of the progress made to date and also to give an insight into the new approaches that can be used to solve outstanding problems. It covers progress in areas including: what grain structure; structural features of the gluten proteins; structual-functionality relationships of wheat protein; lipid-binding proteins; rheology of dough systems; and the importance of non-starch polysaccharides.

Wildlife Feeding and Nutrition

 

Academic Press, 1983.

ISBNs 9780125893800

Colección: ScienceDirect

Resumen (en inglés): Wildlife Feeding and Nutrition is the fifth in a series of books on animal feeding and nutrition. It fills a serious gap in the wildlife and animal nutrition literature by providing a discussion of the basic principles of nutrition and their application to the broader field of wildlife ecology. This book is based on lectures presented in an upper-level wildlife nutrition course taught at Washington State University.
The book discusses the five major nutritional categories of constituents that animals must acquire from their external environments: energy, protein, water, minerals, and vitamins. Subsequent chapters cover topics such as the estimation of energy and protein requirements; dietary protein requirements for captive wildlife and free-ranging populations; wildlife reproductive characteristics; the digestion and metabolism of nutrients; and food intake regulation.
The text will be invaluable to wildlife biologists, to those who are interested in captive animal nutrition and management, and to those who are interested in improving the feed supply and nutrition of free-ranging wildlife.

Wood a Agricultural Residues

Research on Use For Feed, Fuels, and Chemicals

 

Academic Press, 1983.

ISBNs 9780126545609

Colección: ScienceDirect

Resumen (en inglés): Wood and Agricultural Residues Research on Use for Feed, Fuels, and Chemicals covers the proceedings of the 1982 “Feed, Fuels, and Chemicals from Wood and Agricultural Residues” symposium, held in Kansas City and sponsored by Cellulose, Paper, and Textile Division of the American Chemical Society. Organized into seven parts encompassing 31 chapters, the book discusses the plant cell wall; the cellulose, hemicelluloses, and lignin; the lignocellulosics for ruminants; the biological and thermochemical conversion; and the approached for utilization.
The introductory part describes the anatomy, permeability, ultrastructure, and digestion of plant cell wall. The following section examines the structure, characteristics, derivatives, recycle and recovery through solvent systems, and utilization for enzyme and protein production of cellulose and hemicelluloses. This section also discusses the synthesis, structure, properties, and analysis of hydroxypropyl lignin derivatives. The third section characterizes the fibrous fractions of forages and presents traditional methods for qualitative and quantitative analyses of lignocellulosics. This text includes discussions on methods for improving utilization of unconventional feed sources by ruminants; the digestion impeding factors; and the effect of chemical, physical, and biological treatments in upgrading the digestibility and nutritive value of crop residues. The subsequent sections describe the biological, chemical, physical, and thermochemical conversion of wood fibers. Such methods include fermentation, acid and steam hydrolysis, saccharification, hydrogenolysis, and pyrolysis. The concluding section covers mechanical treatments to improve lignocelluloses properties, such as steam explosion and solvent systems.
This book is an ideal source of information for botanists and feed scientists and researchers.

Woody Plant Communities

 

Academic Press, 1981.

ISBNs 9780124241565

Colección: ScienceDirect

Resumen (en inglés): Water Deficits and Plant Growth, Volume VI: Woody Plant Communities focuses on the water relations of woody plants in a community context.
Organized into eight chapters, this book begins with a quantitative overview of sources of water available to woody plants. Separate chapters follow that discuss the water relations of coniferous, temperate hardwood, and tropical and subtropical forests and woodlands; apple and citrus orchards; closely related woody plants; and tea plantations. For each of these plant communities, emphasis is placed on hydrological cycles; water use and transpiration; absorption of water; and effects of environmental factors on soil and plant water balance. The effects of water deficits on physiological processes; vegetative and reproductive growth; yield of harvested products; drought resistance; and cultural practices affecting plant water balance and yield are also emphasized in this book.
This volume will be useful to both researchers and those involved in the practice of growing woody plants for wood and fruit crops and for esthetic values.

Working with Dynamic Crop Models

Methods, Tools and Examples for Agriculture and Environment

 

2nd ed. Academic Press, 2014.

ISBNs 9780123970084

Colección: ScienceDirect

Resumen (en inglés):

This second edition of Working with Dynamic Crop Models is meant for self-learning by researchers or for use in graduate level courses devoted to methods for working with dynamic models in crop, agricultural, and related sciences.

Each chapter focuses on a particular topic and includes an introduction, a detailed explanation of the available methods, applications of the methods to one or two simple models that are followed throughout the book, real-life examples of the methods from literature, and finally a section detailing implementation of the methods using the R programming language.

The consistent use of R makes this book immediately and directly applicable to scientists seeking to develop models quickly and effectively, and the selected examples ensure broad appeal to scientists in various disciplines.

New to this edition:

  • 50% new content – 100% reviewed and updated
  • Clearly explains practical application of the methods presented, including R language examples
  • Presents real-life examples of core crop modeling methods, and ones that are translatable to dynamic system models in other fields
