The chapters in this book discuss various facets of plant environmental stress that are of critical importance to those who are concerned with the production of horticultural or agronomical plants on a large scale. Although not all aspects of plant environmental stress have been included in this publication, (for example, anerobiosis, pathogens, and pesticides) the subjects covered are those of major concern to various commodity groups in given regional sections of the United States. For example, in the northeastern, northern, Rocky Mountain, and midwest areas, freezing temperatures are a major problem. As one moves toward the northwest, west, south central, and southeast regions, chilling damage seems to be an additional dominant factor. Finally, in the arid locations of the southwest, drought, heat, and salt stress take their toll on economically important plants. Many talented scientists are involved in the study of environmental plant stress.
