The hybrids of Hippeastrum, also known by gardeners as amaryllis, have long been popular indoor plants, their flamboyant blooms bringing cheer during the dark winter months. This book for gardeners describes the astonishing range of hybrids now available and explains how to get the best results from these rewarding plants whether grown indoors, outdoors, or under glass.
The volume on oilseed crops is developed as a part of a series on “Handbook of Agrobiodiversity: Conservation and Use of Plant Genetic Resources”. The handbook would function as a ready reference book for availability of PGR globally, along with specific source, wherefrom they can be procured, and used breeding programs, particularly to overcome various crop production constraints and to improve productivity and quality. The volume on floriculture and ornamental plants will be the source of basic information on origin and evolution and global dispersal of cultivated species of ornamentals. Presently, floriculture has established its credibility in improving income through increased productivity, generating employment and in enhancing exports. All research and developmental activities on ornamental crops are essentially multi-disciplinary in nature recognizing local issues as well as country issue. Floriculture is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. Floriculture has progressed both scientifically and commercially due to concentrated efforts made on multidisciplinary research. It is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. The volume will contain all information about different ornamentals. This shall be put together to develop a complete documentation of the results of the research and demonstrations conducted by different scientists. The volume will provide an illustrated horto-taxonomical account of important ornamental species and cultivars, germplasm status and their usages, propagation, nursery management, techno-economics, conventional breeding, induced mutagenesis, new varieties, cytogenetics, tissue culture, characterization of varieties, dehydration of flowers etc. This volume will give a coherent and concise account on recent developments. It will deal with all the important and relevant aspects of floriculture. The publication of this volume is planned to reveal multifarious activities done on different aspects of floriculture so that innovations made so far can be used judiciously for this sector. This book shall provide authoritative review account of many aspects of current interest and progress in the field of floriculture. The topics included in the book are interdisciplinary and cater not only classical floriculture but also relevant modern aspects. The book will provide valuable data on different aspects and will be widely accepted by by professional scientists, researchers, teachers, students, floriculturists, technocrats and planners. The volume will be an invaluable asset to floriculture scientists.
Describes the development of each variety of amaryllis from bulb to flower, discusses the natural history of the amaryllis, and provides practical advice on cultivation, storage, propagation, and hybridization.
The first complete classification for the genus, this labor of love reflects the author's long fascination with hostas. All hostas known at the time of writing are detailed, including their 3500 names and synonyms in many languages (300 in Japanese kana). Practical information on growing hostas is just as complete and detailed.
The Origin of Species by Charles Darwin must rank as one of the most influential and consequential books ever published, initiating scientific, social and religious ferment ever since its first publication in 1859. Its full title is The Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, in some editions prefaced by the word “On.” Darwin describes the book as simply an “abstract” of his ideas, which are more fully fleshed out and supported with detailed examples in his other, more scholarly works (for example, he wrote several long treatises entirely about barnacles). The Origin of Species itself was intended to reach a wider audience and is written in such a way that any reasonably educated and thoughtful reader can follow Darwin’s argument that species of animals and plants are not independent creations, fixed for all time, but mutable. Species have been shaped in response to the effects of natural selection, which Darwin compares to the directed or manual selection by human breeders of domesticated animals. The Origin of Species was eagerly taken up by the reading public, and rapidly went through several editions. This Standard Ebooks edition is based on the sixth edition published by John Murray in 1872, generally considered to be the definitive edition with many amendments and updates by Darwin himself. The Origin of Species has never been out of print and continues to be an extremely popular work. Later scientific discoveries such as the breakthrough of DNA sequencing have refined our concept of some of Darwin’s ideas and given us a better understanding of issues he found puzzling, but the basic thrust of his theory remains unchallenged. This book is part of the Standard Ebooks project, which produces free public domain ebooks.
In 'On the Origin of Species By Means of Natural Selection' by Charles Darwin, the groundbreaking text explores the process of evolution through natural selection. Written in a clear and scientific style, the book delves into the diversity of species and the mechanisms that drive their development. Darwin's careful observations and detailed explanations provide a thorough understanding of the principles of evolution, placing the work in the historical context of the scientific revolution of the 19th century. The book showcases Darwin's keen insight and analytical thinking, making it a landmark in the field of biology and evolutionary theory. From the classification of species to the concept of branching descent, 'On the Origin of Species' is a must-read for anyone interested in the origins of life on Earth. Charles Darwin, a renowned naturalist, was influenced by his extensive travels and observations, leading him to propose the theory of natural selection. His dedication to scientific research and commitment to studying the natural world culminated in this seminal work that forever changed the way we view life and its origins. For readers interested in evolutionary biology and the intricacies of natural selection, 'On the Origin of Species' by Charles Darwin is an essential read that will broaden your understanding of the processes that shape the diversity of life on Earth.
