Book excerpt: Excerpt from The Importance of Seed Characteristics in the Natural Reproduction of Coniferous Forests Periodicity Of the seed years is variable; so much so that it can not be considered in any practical application in planning for future forest work. It must, however, be considered in determining when the latest heavy crop Of seed was produced. The forests produce seed sometimes annually and sometimes at periods of two or three years or even more. It is sufficient to know for the purposes of management, whether the latest crop was a sparse, medium, or heavy one.

Download or read book Conifer Reproductive Biology written by Claire G. Williams and published by Springer Science & Business Media. This book was released on 2009-05-19 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: When it comes to reproduction, gymnosperms are deeply weird. Cycads and co- fers have drawn out reproduction: at least 13 genera take over a year from polli- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to w- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations. This alternation between diploid and haploid generations was eventually to become one of the key unifying ideas in plant evolution. Dr. Williams points out that alter- tion of generations in conifers shows strong divergence in the evolution of male and female gametes, as well as in the synchronicity of male and female gamete development. How are these coordinated to achieve fertilization? Books on conifer reproduction are all too rare. The only major work in the last generation was Hardev Singh’s 1978 Embryology of Gymnosperms, a book that summarized the previous century’s work. Being a book primarily about embry- ogy, it stopped short of putting conifer reproduction in a genetic or evolutionary context.

Available in PDF, EPUB and Kindle. Book excerpt: Dendrology: Cones, Flowers, Fruits and Seeds offers a comprehensive overview of the morphology of reproductive organs of woody plants of Europe in one resource. The book contains 2020 woody taxa (845 species, 58 subspecies, 38 varieties, 13 forms, 40 hybrids and 1026 cultivars), belonging to 400 genera and 121 families. It includes 447 taxa of trees and shrubs that are autochthonous in Europe and numerous ornamental species that originate from North America, Asia, South America, Australia and Africa, along with invasive woody species. Accompanied by thousands of original photographs, the book is designed to efficiently guide the reader to accurate identification. Other features include taxa organized in alphabetical order of their botanical names, flowering and fruiting time, mode of fruit or seed dispersal, and distribution range, making this a must-have reference for students and researchers in dendrology, botany, forestry, forest management and conservation, arboriculture and horticulture. Includes 2,020 taxa of trees and shrubs important for the European dendrology Provides detailed descriptions of reproductive organs and data on the reproductive biology of the described taxa Contains 6,644 original, high-quality photographs of habits, cones, flowers, fruits and seeds

This book was released on 2017-11-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first truly modern book solely devoted to seed reproduction of forest trees-from flowering to establishment, with emphasis on the interaction of environment with physiological processes. Focus is on seed function in natural settings and the application of information to natural regeneration of forests. This easy-to-read text addresses important principles and provides in-depth coverage of existing literature. Presentation of the information is organized to allow for a natural development of the main theme with full explanations of such important components as seed production, dispersal and germination, as well as the integral parts played by water, temperature, light, chemicals, animals, pathogens and aging. A highly useful book for investigators, practitioners or students.

Download or read book Resource Physiology of Conifers written by William K. Smith and published by Gulf Professional Publishing. This book was released on 1995 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coniferous forests are among the most important of ecosystems. These forests are widespread and influence both the financial and biological health of our globe. This book focuses attention on conifers and how these trees acquire, allocate, and utilize the resources that sustain this crucial productivity. An international team of experts has surveyed and synthesized information from an expanding area of inquiry. The first half of the book describes how resources are acquired both by means of photosynthesis and through root systems. The latter half of the volume focuses upon how resources are stored and used. As conifers continue as a resource and ever increasingly important contributor to the regional and global environmental sustainability, this book will help establish how much sustainability can be expected and maintained.
