Ecological and genetic control of plant resistance to unfavorable environmental influences is being carried out all over the world, and new varieties and hybrids of plants are being created, resulting in rich, new information and innovative new methods of cultivation. This new volume, Temperate Horticulture for Sustainable Development and Environment: Ecological Aspects, explores the vast biotic diversity in horticulture, with a focus on sustainable development in today's deteriorating environment. The book offers new technologies for a wide range of horticultural crops, including vegetables, fruit, berries, and flowers. The information presented here is the result of original experiments and study of leading specialists in horticulture, plant breeding, and related areas. Part 1, Innovation in the Field of Vegetable Growing, looks at several completely new methods for increasing the yield of potatoes and cucumbers. The second part. The Arctic Berries: Ecology and Biochemistry presents an abundance of data on the phytocenotic properties of wild-growing and cultivated berry plants and of arctic raspberry and blueberry in natural populations of taiga zones. The authors studied berry crops, cranberry, Arctic bramble, blueberry, Arctic raspberry, cowberry, growing on the boggy soil and peatlands in taiga zones. Part 3, Decorative Plants: Breeding and Biochemistry, provides an overview of winter garden plants and their successful cultivation, looks at the range of resistance to salinization and other stresses of ornamental plants growing, and presents a biochemical analysis of biological active compounds and antioxidants among various species of the genus Aloe. Part 4, on Fruit Growing and Breeding, reviews various technologies for the cultivation of various fruits and presents an overview of data on breeding rare fruit crop. This volume will be useful for the scientific community, ecologists, geneticists, breeders, and industry professionals interested in using science to implement practical applications in production of fruits, vegetables, and flowers.

Heavy metal pollution represents a global challenge to both public health and environmental sustainability. Any means to reduce heavy metal pollution in the environment is of considerable economic significance. The use of green plants to clean up heavy metal pollution is an environmentally friendly as well as a low-cost approach to the problem. This plant-based biotechnology is commonly known as ‘phytoremediation’. Presently, there is limited application of this technology because useful plants with enhanced heavy metal resistance/tolerance are still needed to assist remediation of environments polluted with heavy metals. A key to improved phytoremediation of heavy metal pollution lies in research seeking for a better understanding of the mechanism(s) of heavy metal resistance/tolerance in plants. This E-book presents a unique treatment of the topics that have never been comprehensively brought together before in a single advanced reference. The volume explores aspects of plant biology that are critical for employing phytoremedation techniques to combat heavy metal contamination such as the specific plant biology, seed biology, plant tissue culture and enzymology. This E-book will be a useful reference to plant biologists, biotechnologists and environmental engineers seeking information about phytoremediation of heavy metals from the environment.

The 12th International Symposium on Plant Lipids was held at the University of Toronto, Canada, from July 7th to 12th, 1996. The conference was attended by over 200 scientists from university, government and corporate laboratories from 24 different countries. The topics covered in the symposium ranged from basic physiology, biochemistry and molecular biology of plant lipids to transformation and genetic engineering of crop plants. Oil seed plants were a particular focus of the symposium. There were 62 oral and 96 posters presentations. A special lecture in memory of the founder of this series of symposium, Terry Galliard, was presented by John Shanklin. This Proceedings Book has been dedicated to Grattan Roughan for his important contributions to our knowledge of plant lipid metabolism. This volume contains manuscripts submitted from most of the presentations at the symposium. It provides a useful summary of the major fields of plant lipid studies and our present state of knowledge. The papers are arranged in eight sections covering the major areas in the field of plant physiology, biochemistry and molecular biology of plant lipids. We would like to thank Valerie Imperial, Rajesh Khetarpal and Mary Williams for their invaluable help in organizing and running the meetings and excursions. John P. Williams, Mobashsher U. Khan and Nora W. Lem Toronto, Canada, October 1996 xvii DEDICATION This volume is dedicated to Grattan Roughan.

The book focuses on heavy metals that have damaged the ecosystem Earth and its life forms. It characterizes natural and anthropogenic sources of pollutants, identifies physical, chemical and biological conditions that affect their ecosystem mobility. The book describes the pathways by which potentially toxic metals can access and concentrate to toxic levels in organisms. The text reviews the different environmental assessment, monitoring samples and analytical techniques used to determine how sample types bond the metals and hence affect their bioavailibility and bioaccumulation. Consideration is given to existing remediation methodologies and those being researched. Finally, the book emphasizes how pre-planning during project studies can result in the incorporation of technologies that will prevent or at least greatly alleviate the release of toxic metals to our living environment.
