Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Vitality and Germination of Seeds It has long been known that the conditions under which plants are grown and the degree of maturity at the time of harvesting are fac tors which play an important part in the life of seeds. But, granting that seeds are of strong vitality at the time of harvesting, there remain to be considered the methods of gathering and curing, the water content of the seed at the time of storing, the methods of stor age, the humidity and temperature of the surrounding atmosphere, the composition of the seed, the nature of the seed coats, activities within the cells, and numerous other factors which play important parts in the life of the seed. The conditions necessary for the successful germination of a seed of good vitality and the chemical transformations accompanying these early stages of development have received considerable attention from numerous investigators. These changes and conditions are fairly well understood for many of our common seeds. However, several impor tant facts still remain unexplained, and our knowledge will not be complete until each and every species has'been carefully studied.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Rôle of Seed Coats in Delayed Germination: A Dissertation Submitted to the Faculty of the Ogden (Graduate) School of Science in Candidacy for the Degree of Doctor of Philosophy (Department of Botany) Arthur found that both seeds of the cocklebur take up water readily while in the bur. The bur, therefore, does not account for the delay. He also believes that the extremely delicate seed coats are in no way different in the two seeds and that the structure of the seeds, therefore, offers no explanation of their germinative difference.

Download or read book Effect of Light on Germination of Light Sensitive Seeds written by Wright Austin Gardner and published by Forgotten Books. This book was released on 2018-05-02 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Light on Germination of Light-Sensitive Seeds: A Dissertation Various explanations have been offered for the germination of light-sensitive seeds, and several conditions have been shown to favor or make possible the germination of such seeds. Rupture of coats, increased water supply, variation of quantity and intensity of light, reciprocal relation of heat and light, reaction of substratum and embryo, activation of enzymes, increased oxygen pressure, increased carbon dioxide pressure, and certain inhibiting agencies have been suggested as factors affecting the germination of light sensitive seeds. Although quite possible, it seems hardly probable that no one of these is the fundamental or controlling factor. It would seem quite probable that one or two of these agencies are fundamental and the others are accessory means of setting in motion the processes that finally bring about germination. Enzyme action has been suggested repeatedly as a fundamental cause of germination, but no one has ventured to demonstrate the relation of enzymes to the germination of light-sensitive seeds. An attempt has been made in this investigation to discover the fundamental relation of light to the germination of seeds, and to show just what light does to start germination. The effect of light on the germination of seeds has interested botanists for many years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from O. A. C. Review, Vol. 35: March 1923 Sweet Clover seed is characterized by having 'a very'high percentage of seeds which' are covered with a hard seed coat impermeable to water. This seed imay live -ih the soil, for several seasons without germinating, but once' the seed coat is cracked or broken, through the influence of frost or heat, and the water. Allowed to permeate, the seed will germinate and grow. This peculiar characteristic of the seed causes considerable difficulty with sweet clover in subsequent crops. In the scarifying process an attempt is made to break the seed coat by some mechanical means prior to sowing the seed, thus ensuring a large germination and less difficulty with the crop later.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.
