Download or read book Genus Medicago Leguminosae written by K.A. Lesins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: In introducing ourselves it should be told that in our native Latvian language our name is written LesiJ;l. s. In most English publications, as in this work, the writing has been simplified to Lesins, and often only the first initial has been used. Our interest in Medicago was first aroused during 1936-38, while em ployed as teachers in the agricultural and home economics school at Be brene, Upper Zemgale, Latvia. Some plants of alfalfa (M. varia, M. media), locally called 'lucema', were found growing wild along roadsides in that area, though no alfalfa fields had been seen in the vicinity within the me mory of local farmers. Some roadside plants were dug out and transplanted to the garden, but their seedset was poor. During the next few years we paid only slight attention to alfalfa, the reason being that Latvia is a country with Atlantic climatic features (annual precipitation 600-700 mm; mild win ters for its 56°-58° N. Lat. , with January isotherms between -3° and -7° C; moderately warm summers, with July isotherms between 16° and 18° C), which together with its soils, mostly of acidic, podzolic type, is not well suited for alfalfa production. It was not until 1945 in Sweden that work on alfalfa came to the foreground, when the senbor author was assigned investi gations on alfalfa seed setting by Dr. Erik Akerberg, then director of the Swedish Seed Association branch station at ffituna.
Download or read book Red Clover Science written by N.L. Taylor and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 246 pages.

Download or read book Molecular Systematics of Plants II written by Pamela Soltis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the five years since the publication of Molecular Systematics of Plants, the field of molecular systematics has advanced at an astonishing pace. This period has been marked by a volume of new empirical data and advances in theoretical and analytical issues related to DNA. Comparative DNA sequencing, facilitated by the amplification of DNA via the polymerase chain reaction (PCR), has become the tool of choice for molecular systematics. As a result, large portions of the Molecular Systematics of Plants have become outdated. Molecular Systematics of Plants II summarizes these recent achievements in plant molecular systematics. Like its predecessor, this completely revised work illustrates the potential of DNA markers for addressing a wide variety of phylogenetic and evolutionary questions. The volume provides guidance in choosing appropriate techniques, as well as appropriate genes for sequencing, for given levels of systematic inquiry. More than a review of techniques and previous work, Molecular Systematics of Plants II provides a stimulus for developing future research in this rapidly evolving field. Molecular Systematics of Plants II is not only written for systematists (faculty, graduate students, and researchers), but also for evolutionary biologists, botanists, and paleobotanists interested in reviewing current theory and practice in plant molecular systematics.

Download or read book Flora of Alaska and Neighboring Territories written by Eric Hultén and published by Stanford University Press. This book was released on 1968 with total page 1050 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.
Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.
Download or read book Fungal Ecology written by Neville J. Dix and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi play vital roles in all ecosystems, as decomposers, symbionts of animals and plants and as parasites. Thus their ecology is of great interest. It has been estimated that there may be as many as 1. 5 million species of fungi, many of which are still undescribed. These interact in various ways with their hosts, with their substrates, with their competitors (including other fungi) and with abiotic variables of their environment. They show great variation in morphology, reproduction, life cycles and modes of dispersal. They grow in almost every conceivable habitat where organic carbon is available: on rock surfaces, in soil, the sea and in fresh water, at extremes of high and low temperature, on dry substrata and in concen trated solutions. Fungal ecology is therefore an enormous subject and its literature is voluminous. In view of this we have had to be selective in the material we have included in this book. We have chosen to concentrate on subjects in which we have some personal experience through either research or teaching. We preferred to tackle a few subjects in depth instead of attempting to cover a wider range of topics superficially. We are conscious of the extensive gaps in coverage: for example on the ecology of lichens, of fungal plant pathogens and of the complex interactions between fungi and animals. It is some justification that book-length treatments of these subjects are available elsewhere.
