Floral Biology by David G. Lloyd,Spencer C.H. Barrett Pdf

Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Floral Biology by M. Percival Pdf

Floral Biology attempts to show how floral biologists conduct their experiments and what techniques they employ in floral biology. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. Organized into 11 chapters, this book begins with a discussion on sex in flowers; the biology of the floral parts; agencies of pollination; and the pollen, nectar, and nectaries. Some chapters follow on pollination by birds, bats, and insects. The features of entomophilous flowers and isolating mechanisms in flowers are also described. Some hints for students, such as the tools required, how to make them, and a schedule of procedure for examining the floral biology of a species, are given in the last chapter. This book will attract workers, who, armed with the techniques and stimulated by the findings of the investigators, can introduce the floral biology to other fields.

Understanding Flowers and Flowering Second Edition by Beverley Glover Pdf

Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.

Biology of Floral Scent by Natalia Dudareva,Eran Pichersky Pdf

As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and ob

Pollination and Floral Ecology by Pat Willmer Pdf

Pollination and Floral Ecology is the most comprehensive single-volume reference to all aspects of pollination biology--and the first fully up-to-date resource of its kind to appear in decades. This beautifully illustrated book describes how flowers use colors, shapes, and scents to advertise themselves; how they offer pollen and nectar as rewards; and how they share complex interactions with beetles, birds, bats, bees, and other creatures. The ecology of these interactions is covered in depth, including the timing and patterning of flowering, competition among flowering plants to attract certain visitors and deter others, and the many ways plants and animals can cheat each other. Pollination and Floral Ecology pays special attention to the prevalence of specialization and generalization in animal-flower interactions, and examines how a lack of distinction between casual visitors and true pollinators can produce misleading conclusions about flower evolution and animal-flower mutualism. This one-of-a-kind reference also gives insights into the vital pollination services that animals provide to crops and native flora, and sets these issues in the context of today's global pollination crisis. Provides the most up-to-date resource on pollination and floral ecology Describes flower advertising features and rewards, foraging and learning by flower-visiting animals, behaviors of generalist and specialist pollinators--and more Examines the ecology and evolution of animal-flower interactions, from the molecular to macroevolutionary scale Features hundreds of color and black-and-white illustrations

Breeding of Horticultural Crops by N. Kumar Pdf

The book has been designed with the main consideration to serve a dual purpose of being a text and reference. Keeping this thing in mind the entire book has been divided into three major parts. The first part deals with the principles and methods of breeding adopted in horticultural crops propagated both sexually and asexually. The second part deals with the achievements in breeding of perennial horticultural crops. The third part covers achievements made in breeding of annual horticultural crops.

Reproductive Ecology of Flowering Plants: Patterns and Processes by Rajesh Tandon,K. R. Shivanna,Monika Koul Pdf

Sexual reproduction is the predominant mode of perpetuation for flowering plant species. Investigating the reproductive strategies of plants has grown to become a vast area of research and, in crop plants, covers events from flowering to fruit and seed development; in wild species, it extends up to seed dispersal and seedling recruitment. Thus, reproduction determines the extent of yield in crop plants and, in wild plants, also determines the efficacy of recruiting new adults to the population, making this field important both from fundamental and applied plant biology perspectives. Moreover, in light of the growing concerns regarding food and nutritional security for the growing population and preserving biological diversity, reproductive biology of flowering plants has acquired special significance. Extensive studies on various facets of reproduction are being carried out around the world. However, these studies are scattered across research journals and reviews from diverse areas of biology. The present volume covers the whole spectrum of reproductive ecology, from phenology and floral biology, to sexuality and pollination biology/ecology including floral rewards, breeding systems, apomixis and seed dispersal. In turn, transgene flow, its biosafety and mitigation approaches, and the ‘global pollinator crisis’, which has become a major international concern in light of the urgent need to sustain crop yield and biodiversity, are discussed in detail. Given its scope, the book offers a valuable resource for students, teachers and researchers of botany, zoology, ecology, agriculture and forestry, as well as conservation biologists.

The Reason for Flowers by Stephen Buchmann Pdf

“Fascinating...Buchmann’s knowledge and enthusiasm jump off the page.” —The Wall Street Journal “An extraordinarily good book.” —Edward O. Wilson The lively and definitive story of the beauty, sexuality, lore, economics, and ecology of the world ’s flowers, written by a devoted scientist and illustrated with his stunning photographs. Flowers—and the fruits they often become—feed, clothe, and inspire us. Indeed, they have done so for all of human history. Yet although we use flowers to celebrate important occasions, to express love, and to please our senses, we know little about them, their functions in nature, or even how we depend on them. In a volume that will delight gardeners, naturalists, cooks, artists, or anyone interested in history or culture, pollination ecologist Stephen Buchmann serves as an expert guide through the fascinating world of flowers. He explains how other species relate to flowers in ways crucial to the natural world. Next he takes us on an engaging exploration of the roles flowers play in the production of food, spices, medicines, and perfumes. Flowering plants, Buchmann then shows, have long served as inspirational themes in art and literature. Flowers have in fact so thoroughly seduced us that we now buy some ten million a day, driving breeders to create infinite varieties and unusual blooms. In this cultural and natural investigation of floral history, Stephen Buchmann’s masterful narrative illuminates just why there is, indeed, a reason for flowers.
