Book Description
This publication opens with the inevitable introduction, moves on to the present traditional approach to breeding for yield stability, and then enumerates a detailed discussion of the physiological approach to breeding for resistance to specific stresses. Not all environmental stresses are covered, omitting those for which little can be said today on practical breeding solutions.

Book Description
This timely work reviews the best current thinking on practicing sustainable agriculture, with contributions from agricultural, biological, environmental and social scientists. The emphasis is on temperate zones, with many of the contributions addressing U.S. agriculture. However, the principles explored here have application in any climatic or geographical region. The book discusses stewardship, biodiversity, reliance on mixed food systems and other approaches, always with a view toward reducing environmental degradation, maintaining economic viability and stabilizing rural communities.

Book Description
This volume provides a synthesis of recent work on evolutionary aspects of metal tolerance in plants. It presents contributions from scientists with a wide diversity of expertise. It covers the evolution of heavy metal tolerance in groups of plants, fungi, and protists. The book discusses the physiological, genetic and molecular aspects of metal tolerances. It deals with the evolution of populations in metal-contaminated environments. Several chapters include tolerance in animals in order to place the rest of the book on plants in proper perspective. This publication is an exciting addition for scientists with both applied and basic interest in metal toxicity and tolerance. It is of importance to those in vegetation ecology, land reclamation, agronomy, physiology, population ecology, ecological genetics, evolutionary biology and molecular biology.

Book Description
The contributions of plant genetics to the production of higher yielding crops of superior quality are well documented. These successes have been realized through the application of plant breeding techniques to a diverse array of genetically controlled traits. Such highly effective breeding procedures will continue to be the primary method employed for the development of new crop cultivars; however, new techniques in cell and molecular biology will provide additional approaches for genetic modification. There has been considerable speculation recently concerning the potential impact of new techniques in cell and molecular biology on plant improvement. These genetic engineering techniques should offer unique opportunities to alter the genetic makeup of crops if applied to existing breeding procedures. Many questions must be answered in order to identify specific applications of these new technologies. This search for applications will require input from plant scientists working on various aspects of crop improvement. This volume is intended to assess the interrelationships between conventional plant breeding and genetic engineering.

Book Description
Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

Book Description
Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas. This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

Book Description
This book presents comprehensive coverage of differentiated plant responses to changing environments. It focuses on how multiple and combined stress factors influence plant survival. It examines the latest data on the capacity of roots to alter growth patterns due to disturbances in physical and/or chemical soil constraints, water supply, and other traumas. It contains over 85% new and updated material with more than 1500 new citations, tables, drawings, and photographs.
