Download or read book Modern Phytochemical Methods written by Nikolaus H. Fischer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains reviews which are based on a symposium, given th at the 30 meeting of The Phytochemical Society of North America, held at Laval University in Quebec City, Canada on August 11-15, 1990. During the past two decades, there have been major new developments in methods which can be applied toward the isolation, separation and structure determination of complex natural products. Therefore, the topic of this symposium, "Modem Phytochemical Methods", is a very timely one. The organizers of the symposium recognized that it would not be possible to cover in detail all new advances in phytochemical methodology. It was therefore decided to emphasize general reviews on recent developments of major separation techniques such as high performance liquid chromatography as well as supercritical fluid chromato graphy. In addition, advances in commonly used structure determination methods, mainly NMR and MS, are reviewed. Other topics include methodo logies of micro-sampling for isolation and analysis of trichome constituents as well as recent breakthroughs on biosynthetic studies of monoterpenes using "enriched" basal cells of trichomes. The volume concludes with a review of quantitative structure-activity relationship (QSAR) studies of biologically active natural products. In Chapter I, K. Hostettmann and his colleagues give a general review of recent developments in the separation of natural products with major emphasis on preparative separations of biologically active plant constituents. The authors present a comparison of droplet countercurrent chromatography (OCCC) with the highly rapid and more versatile centrifugal partition chromatography (CPC).

Download or read book Reproductive Ecology of Flowering Plants Patterns and Processes written by Rajesh Tandon and published by Springer Nature. This book was released on 2020-08-07 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diversity and Evolution of Land Plants provides a fresh and long overdue treatment of plant anatomy and morphology for the biology undergraduate of today. Setting aside the traditional plod through the plant taxa, the author adopts a problem-based functional approach, exploring plant diversity as a series of different solutions to the design problems facing plant life on land.

The plain facts of life from all areas of biology, including such topics as growth rates of hair and nails, and ages and weights of seeds are simply fascinating. Biology comes alive in this comprehensive and entertaining reference work. Warning: Anybody who begins browsing through this book will not easily stop reading!

Download or read book Flowering Plants written by K. Kubitzki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented.
