Flower Seeds: Biology and Technology
The ornamental industry has changed substantially in the last 20 years. The science of flower seed technology has also advanced rapidly to keep up with new market demands. There is much information scattered in various scientific and trade publications, and more is being kept in the proprietary domain of seed companies. Anyone searching for information on flower seeds finds it in short supply and seldom collated into one comprehensive reference.
The objective of this book is to update the reader on the current state of knowledge about flower seeds in one common resource. Because the topic is broad and complex, no one individual could have authored such a treatise. As a result, we have taken the approach of identifying experts knowledgeable in specific areas of flower seeds. As editors, our role has been twofold: (i) to ensure that each author provided comprehensive
technological detail about each subject; and (ii) to ensure a consistency in editing style and presentation for the reader.
The book is arranged in three sections. The first section (Chapters 2–4) provides an introduction to the flower seed industry and identifies the users of flower seeds. These chapters provide a historical treatment of the industry and emphasize the challenges and opportunities for the ornamental and bedding plant and wildflower industries. The second section (Chapters 5–10) considers the science of flower seed production. How do seed companies establish successful breeding programmes? What factors control flower induction so that not only the highest quality seeds are produced, but yields are maximized? What is the structure and anatomy of flower seeds? What physiological events govern seed germination, dormancy imposition and release, and seed deterioration?
These important topics are considered in detail. The third section (Chapters 11–17) discusses the technology of flower seeds. This includes chapters on cleaning, enhancements, germination, viability and vigour testing of flower seeds. Here, for the first time, are specific guidelines and information to accomplish these tasks. A chapter is also provided describing the activities of the Ornamental Plant Germplasm Center – the only governmental organization dedicated to conserving germplasm for the future genetic improvement of flower crops.
