The gaseous molecule ethylene (C2H4), which is small in size and simple in structure, is a plant hormone most often associated with fruit ripening yet has a diversity of effects throughout the plant life cycle. While its agricultural effects were known even in ancient Egypt, the complexity of its mode of action and the broad spectrum of its effects and potential uses in plant physiology remain important scientific challenges today. In the last few decades, the biochemical pathway of ethylene production has been uncovered, ethylene perception and signaling have been molecularly dissected, ethylene-responsive transcription factors have been identified and numerous effects of ethylene have been described, ranging from water stress, development, senescence, reproduction plant-pathogen interactions, and of course, ripening. Thus ethylene is involved in plant development, in biotic and abiotic stress, and in reproduction. There is no stage in plant life that is not affected by ethylene, modulated by a complex and fascinating molecular machinery.

"a very valuable book for graduate students and researchers in the field of Laser Spectroscopy, which I can fully recommend" —Wolfgang Demtröder, Kaiserslautern University of Technology How would it be possible to provide a coherent picture of this field given all the techniques available today? The authors have taken on this daunting task in this impressive, groundbreaking text. Readers will benefit from the broad overview of basic concepts, focusing on practical scientific and real-life applications of laser spectroscopic analysis and imaging. Chapters follow a consistent structure, beginning with a succinct summary of key principles and concepts, followed by an overview of applications, advantages and pitfalls, and finally a brief discussion of seminal advances and current developments. The examples used in this text span physics and chemistry to environmental science, biology, and medicine. Focuses on practical use in the laboratory and real-world applications Covers the basic concepts, common experimental setups Highlights advantages and caveats of the techniques Concludes each chapter with a snapshot of cutting-edge advances This book is appropriate for anyone in the physical sciences, biology, or medicine looking for an introduction to laser spectroscopic and imaging methodologies.

An irreverent romp through the natural science of gardening, with eye-opening insight and practical guidance for getting the most out of your plants. Curious why caressing your cucumber plants will help them bear more fruit? Or why you should grow oranges from seed even if the fruit is inedible? Or why trees need to sleep and how to help them? Join acclaimed gardener, scientist, and author Lee Reich on a journey through the delights of your garden in this laugh-out-loud treatise on the scientific wonders of plants and soil. The Ever Curious Gardener includes information on: How to maximize both flavor and nutrition in your garden bounty Helping plants thrive during drought Outwitting weeds by understanding their nature Making the best use of compost Tips on pruning and orchard care Why the dead language of Latin can make you a better gardener.

By 2050, we will have ten billion mouths to feed in a world profoundly altered by environmental change. How will we meet this challenge? In How to Feed the World, a diverse group of experts from Purdue University break down this crucial question by tackling big issues one-by-one. Covering population, water, land, climate change, technology, food systems, trade, food waste and loss, health, social buy-in, communication, and equal access to food, the book reveals a complex web of challenges. Contributors unite from different perspectives and disciplines, ranging from agronomy and hydrology to economics. The resulting collection is an accessible but wide-ranging look at the modern food system.

First published in 1927.

The objective of this book is to organize and document the technical, analytical, and practical aspects of present-day apple processing. No collected works have been published on processed apple products for more than thirty years. During that time many changes have taken place in the apple-processing industry. There are fewer but larger plants processing apples from larger geographical areas because of advances in transportation and storage of fruit. In addition sophisti cated technical advances in the processing and packaging of apple products have also occurred. This volume is designed to serve primarily as a reference book for those interested and involved in the processed apple industry. An attempt has been made to provide a central source of historical, currently practical, and theoretical information on apple processing. References have been cited to give credibility and assist those who may wish to read further on a particular subject. If this book success fully summarizes present knowledge for readers and assists in the continued improvement of commercial fruit processing, I will be pleased. I would like to thank the many people in the apple industry who have requested information and encouraged the writing of this book. The late Dr. Robert M. Smock, Professor Emeritus, Cornell Univer sity, and coauthor of Apples and Apple Products, originally published in 1950, gave his blessings and encouragement to this undertaking.
