This book was written for those individuals who are concerned about the techniques and practices of plant cell cultures for horticultural crops. It was designed to serve as a text and reference for students and professionals in ornamental horticulture, fruit and vegetable crop pro­ duction, botany, forestry, and other areas of plant science. Research during the last twenty-five years in the area of plant tissue culture has led to many developments and changes in this field. Al­ though the techniques involved in the manipulation of plant tissue culture are now relatively straightforward, the presentation of these techniques in a short volume for the beginner in the field is generally unavailable. In addition to describing the techniques for establishment and manipulation of specific species, several chapters in this book also provide a brief, general review of important cultural parameters. Spe­ cific protocols and laboratory procedures may also be found in the appendix. I hope that this presentation of information will be helpful to those individuals wanting to apply plant tissue culture techniques for horticultural crops.
