Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

This book was released on 2008-10-08 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree species are indispensable to support human life. Due to their long life cycle and environmental sensitivity, breeding trees to suit day-to-day human needs is a formidable challenge. Whether they are edible or industrial crops, improving yield under optimal, sub-optimal and marginal areas calls for uni?ed efforts from the s- entistsaroundtheworld. Whiletheuniquenessofcoconutaskalpavriksha(Sanskr- meaning tree-of-life) marks its presence in every continent from Far East to South America, tree crops like cocoa, oil palm, rubber, apple, peach, grapes and walnut prove their environmental sensitivity towards tropical, sub-tropical and temperate climates. Desert climate is quintessential for date palm. Thus, from soft drinks to breweries to beverages to oil to tyres, the value addition offers a spectrum of pr- ucts to human kind, enriched with nutritional, environmental, ?nancial, social and trade related attributes. Taxonomically, tree crops do not con?ne to a few families, but spread across a section of genera, an attribute so unique that contributes immensely to genetic biodiversity even while cultivated at the commercial scale. Many of these species in?uence other ?ora to nurture in their vicinity, thus ensuring their integrity in p- serving the genetic biodiversity.

Download or read book Atlas of Wild Potatoes written by and published by Bioversity International. This book was released on 2002 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This atlas describes the ecogeographic distribution of wild potatoes. They occur solely in the Americas, from the southwestern United States to central Argentina and Chile. To help the nonspecialist to understand the past and future changes in their classification, we first discuss the habitats, morphology, and taxonomy of wild potatoes. This is followed by a discussion of problems of data and information quality associated with the locality databases that were used for the maps in this atlas. Distribution maps are provided for all species and series (a taxonomic level that groups related species). Finally, statistics on ecogeographic distribution of wild potatoes, and analytical maps of species richness and series richness are provided.

Download or read book Pratylenchus Nematoda Pratylenchidae Diagnosis Biology Pathogenicity and Management written by Pablo Castillo and published by BRILL. This book was released on 2007-10-30 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root-lesion nematodes of the genus Pratylenchus are recognised worldwide as one of the major constraints of crops of primary economic importance. Pratylenchus spp. comprises around 70 nominal species of worldwide distribution which parasitize a wide variety of plants. The book consists of ten chapters and presents summarised and specialised information concerning the importance of the Pratylenchus species in: agricultural crops, and their world distribution (chapter 1); taxonomy, systematic, general morphology and diagnostic traits of Pratylenchus spp. including new technologies based on biochemical and molecular analyses (chapters 2-6); biology, epidemiology, ecology, host-parasite relationships, and pathogenicity (chapters 7-9). Finally, it illustrates different management strategies for Pratylenchus species, including, crop rotation, host-plant resistance, chemical control, soil solarisation, and biological control (chapter 10).
Download or read book The Family Trichodoridae Stubby Root and Virus Vector Nematodes written by Wilfrida Decraemer and published by Springer Science & Business Media. This book was released on 1995-11-30 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family Trichodoridae was established by Thorne in 1935 but it remained of limited taxonomie interest until 1951 when Christie and Perry associated Trichodorus christie (now Paratrichodorus minor) with a "stubby root disease" that affected certain crops in Florida, USA and interest further increased from 1960 when P. pachydermus was implicated as a vector of the economically important tobacco raule virus. Such discoveries gave an impetus to studies on many aspects of the biology of trichodorid nematodes with a consequent proliferation of new species described from different parts of the world. The number of species increased from twelve in 1957 to a present day total exceeding eighty. This rapid expansion in the number of species was accompanied by several reappraisals of the taxonomy and systematies of the family, the most notable changes being the creation of the genus Paratrichodorus by Siddiqi in 1974 and the recognition of the monodelphic genera Monotrichodorus and Allotrichodorus respectively by Andrassy in 1976 and Rodriguez-M, Sher and Siddiqi in 1978. Reliable and unambiguous identification of taxa is dependent on the known reliability of a range of characters, whieh remains of paramount importance in taxonomy even when biochemical and molecular methodology is available. In this book each of the species, including synonyms and species inquirenda, that comprise the family Trichodoridae is re-described from meticulous mieroscopie examination of type specimens, material from official nematode collections and populations in the field.

Download or read book Plant Parasitic Nematodes of Coffee written by Ricardo M. Souza and published by Springer Science & Business Media. This book was released on 2008-09-02 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: When I conceived this book, what I had in mind was what I did not know about coffee-parasitic nematodes (CPNs). Indeed, after reading many papers and several chapters in books, I felt far from having a comprehensive understanding of the subject. Not only would it be a daunting task to retrieve the numerous articles, reports, theses and dissertations on CPNs published since 1878, but it would also be impossible to learn, on my own, from all the enormous experience acquired by nematologists and coffee growers in so many countries. Therefore, this book is dedicated to those with restless minds, who want to know more about CPNs and their importance in coffee production worldwide. This book has been diligently written by top scientists in their areas of expertise or country, and it has been meticulously edited to guarantee precision without compromising an enjoyable read. I learned a lot from this book...I’m sure you will too. Finally, I’d like to thank Zuzana Bernhart from Springer, who believed in this project and decided to publish it; Susan Casement, who revised all chapters for grammatical correctness; and all the contributors, without whom this book would never have became a reality.
