Available in PDF, EPUB and Kindle. Book excerpt: Biological aspects of orchard-produced Sitka spruce (Picea sitchensis (Bong.) Carr.) seeds were studied for one seed orchard located on the Saanich Peninsula of Vancouver Island, B.C. These aspects include: the determination the level of genetic diversity in the orchard population and its comparison to the species' range estimates, the estimation of the degree of inbreeding in the orchard, seed and cone crop parental balance over two crop years, the genetic control of germination parameters and seed size , the impact of simulated long-term storage on the genetic constitution of bulk seed crops, and the relationships between seed size and genetic origin on their seedling attributes. It was found that: (1 ) Most of the polymorphic allozyme markers investigated segregated according to the expected Mendelian ratio, and no linkage between any pair of these loci was observed; (2) The level of genetic diversity present in the seed orchard population indicated that phenotypic selection of parent trees did not reduce the level of diversity; (3) Significant rates of outcrossing were detected in the seed orchard population ( t[subscript m] = 0.875 ) . Most of this inbreeding occurred in lower branches; (4) Parental imbalance was found for the two crops investigated, however, improvement over time was observed, indicating an age effect; (5) Germination parameters (GC, P V and GV) and seed size were under genetic control with estimates of broad-sense heritabilities of 0.74 - 0.78 and 0.36 , respectively; (6) Artificial aging of seed (i.e., accelerated aging) indicated that reduction in rates of germination were clone-specific; and (7) Seed size showed no effect on seedling attributes, but a significant effect on germination speed was observed.

This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fifth International Workshop on Seeds was held at the University of Reading, UK, from 10 to 15 September, 1995. Some 230 seed scientists, from a wide range of disciplines (botanists, biochemists, ecologists, agriculturalists, foresters, and commercial seedsmen), from 31 countries (Europe, the Americas, and Asia) participated in the workshop. A large number of oral and poster presentations was made during the workshop and we are pleased to publish so many of them in these Proceedings. The papers herein are listed by the sessions in which they were presented but, as is often the case, many papers cover a broader range of topics than the session titles imply. For seed physiologists, ecologists, and technologists, this book collates much of the current research on seeds.

Download or read book Seed Ecology written by M.W. Fenner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the regeneration of plants from seed under field conditions. It attempts to give a reasonably balanced overview of the many aspects of this broad topic. The first chapter introduces some general ideas about reproduction in plants. Subsequent chapters deal with the early stages in the life of a plant, from ovule to established seedling, in a more or less chronological order. The final chapter shows how the data on regeneration requirements of different species can be used to explain a number of important characteristics of whole plant communities. The study of the ecological aspects of reproduction by seed touches on a range of issues of current interest in biology. A discussion of seed size and number involves a consideration of the concepts of resource allocation, life cycles and strategies. The in teractions between plants and animals seen in pollination, seed dispersal and predation provide excellent material for the study of coevolution. Investigations on regeneration from seed have greatly our understanding of the causes and maintenance of species added to diversity. The reader will find that virtually all the experiments and field observations described in this book are conceptually very simple. Many of them merely required numerous careful measurements.

Book Synopsis Ecology and Management of Sitka Spruce by : N. Merle Peterson
Download or read book Ecology and Management of Sitka Spruce written by N. Merle Peterson and published by UBC Press. This book was released on 2011-11-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
Book Synopsis Advances in Seed Biology by : Paolo A. Sabelli
Download or read book Advances in Seed Biology written by Paolo A. Sabelli and published by Frontiers Media SA. This book was released on 2015-11-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seed plays a fundamental role in plant reproduction as well as a key source of energy, nutrients and raw materials for developing and sustaining humanity. With an expanding and generally more affluent world population projected to reach nine billion by mid-century, coupled to diminishing availability of inputs, agriculture is facing increasing challenges to ensure sufficient grain production. A deeper understanding of seed development, evolution and physiology will undoubtedly provide a fundamental basis to improve plant breeding practices and ultimately crop yields. Recent advances in genetic, biochemical, molecular and physiological research, mostly brought about by the deployment of novel high-throughput and high-sensitivity technologies, have begun to uncover and connect the molecular networks that control and integrate different aspects of seed development and help determine the economic value of grain crops with unprecedented details. The objective of this e-book is to provide a compilation of original research articles, reviews, hypotheses and perspectives that have recently been published in Frontiers in Plant Science, Plant Evolution and Development as part of the Research Topic entitled "Advances in Seed Biology". Editing this Research Topic has been an extremely interesting, educational and rewarding experience, and we sincerely thank all authors who contributed their expertise and in-depth knowledge of the different topics discussed. We hope that the information presented here will help to establish the state of the art of this field and will convey how exciting and important studying seeds is and hopefully will stimulate a new crop of scientists devoted to investigating the biology of seeds.
