This book has been designed to introduce to the reader the scientific principles underlying seed science and technology, by setting them against commercial (e.g., seed supply, weed control) as well as non-commercial (e.g., habitat restoration) contexts. It seeks to make a broad understanding of the various pieces that make up the jigsaw puzzle of this science, and probes into the potential and the future of this industry. This book begins the exploration and introduction of seed science by giving an overview of the basic elements like viability, vigour, quality and dormancy. The commercial and economic relevance of this industry is given an in-depth insight into. Apart from that, the different aspects of seed response to the environment, such as effects of pre- and post harvest environment on seed and consequences of subsequent tests, have been thoroughly probed. With a compendious presentation of the subject, readers associated with agricultural science would find this book highly useful.
