内容説明

Seed testing centers exist in almost every country in every corner of the globe. More and more students are enrolling in programs that require knowledge of the complex and fascinating science of seed pathology. The implications of seed pathology for human health remains an important issue. For all of these reasons and more, this book is a necessary and timely reference that covers the full range of related topics, including techniques for detecting and studying microorganisms associated with seeds, their epidemiology, and control. No other book like this exists. Until now, the information has been widely scattered in journals and other sources. This is an excellent new edition - ideal for students and teachers in the agricultural and life sciences; individuals involved in seed certification; members of plant quarantine laboratories; plant pathologists doing research in seed pathology; and producers of planting seeds for the next season's crops.
