Resting spores germinated more rapidly if dried and apparently only in the presence of host roots. In air-dry soil resting spores survived 56 days at -24°C. Minimum, optimum and maximum temperatures for infection of roothairs were below 11°, 14°- 20°, and 22°-25°, respectively. Between pH values of 5.2 and 7.5, soil pH had hardly any influence on invasion of root-hairs. At 16° to 20° the incubation period for tuber and root infection was less than 3 weeks.

Book Synopsis Post-Harvest Diseases and Disorders of Fruits and Vegetables by : Anna L. Snowden
Download or read book Post-Harvest Diseases and Disorders of Fruits and Vegetables written by Anna L. Snowden and published by CRC Press. This book was released on 2010-07-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.

Book Synopsis Ecology of Root Pathogens by : S.V. Krupa
Download or read book Ecology of Root Pathogens written by S.V. Krupa and published by Elsevier. This book was released on 2012-12-02 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Root Pathogens discusses the significance of fungi infecting the roots, and emphasizes the significant diseases of roots and their symptoms. This book also names the genera and species of fungi that cause diseases of roots, and classifies and characterizes the root and pathogen interaction in soil. The book describes the behavior of plant pathogenic bacteria, such as Agrobacterium, Corynebacterium, Xanthomonas, Pseudomonas, Erwinia, and Streptomyces. It also explores how plants and plant-produced stimuli affect the associated population of plant parasitic nematodes and how these plant parasitic nematodes affect higher plants in certain ways. In addition, this book discusses the morphology, classification, nomenclature, multiplication and translocation of viruses infecting the plants. It also describes the symptoms of the virus infection in roots. The book includes a discussion on the fundamentals of biological control, which include the pathosystem concept, the behavior of the soil microflora in the soil, the reservoirs for infection, the processes of pathogen decline, and the integrated effects on the decline of the pathogen. This discussion on biological control also presents the natural and artificially induced biological control. This book will be of great value to soil microbiologists and plant pathologists.

Download or read book The Mycetozoans written by Lindsay Olive and published by Elsevier. This book was released on 2012-12-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mycetozoans brings together, for the first time in a single volume, comprehensive information on the biology and classification of the mycetozoans and associated groups. The mycetozoans and their associates remain of prime interest to taxonomists and phylogenists because major new taxa continue to be discovered among them. This book informs the reader where to find mycetozoans, how to isolate and culture them, their life cycles and ultrastructure, and some of the experiments that may be performed with them. It presents studies on Protostelia (protostelids); Dictyostelia (dictyostelid cellular slime molds); Myxogastria (myxomycetes); Acrasea (acrasid cellular slime molds); Plasmodiophorina (plasmodiophorids); and Labyrinthulas (labyrinthulina and thraustochytrids). This text can serve as a reference tool in courses on mycetozoans, protozoology, mycology, and developmental biology of lower organisms, and as a concentrated source of information for research workers in all aspects of the biology and taxonomy of these organisms.

Book Synopsis Vectors of Plant Pathogens by : Kerry F. Harris
Download or read book Vectors of Plant Pathogens written by Kerry F. Harris and published by Academic Press. This book was released on 2013-10-02 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vectors of Plant Pathogens is a collection of papers that discusses the interrelationship of plant pathogens with their vectors. This collection deals with the numerous vector groups associated with plant pathogens. One paper describes the biology, feeding behavior and distribution of aphids, leafhoppers, plant hoppers, mealy bugs, whiteflies, psyllids, membracids. Another paper addresses the virus transmission characteristics of the mealy bugs during preliminary fasting or feeding, acquisition access time, post-acquisition fasting or feeding, and the inoculation access time. Other papers also discuss the involvement of insects in transmitting bacterial and fungal pathogens; the authors list unresolved issues such as the role of insects in overwintering of bacterial pathogens or the association of the fungus with a particular vector. One author describes some suspected fungi transmission such as the pea stem necrosis virus, red clover necrotic mosaic virus, and the tomato bushy stunt virus. Another paper examines the fate of plant viruses in mite vectors and convectors particularly the viruses found in wheat, barley, or brome grass. Agriculturists, botanists, and researchers in the field of botany, conservation, and plant genealogy will find this book useful.

Book Synopsis Systematics and Evolution by : David J. McLaughlin
Download or read book Systematics and Evolution written by David J. McLaughlin and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an exciting time to produce an overview of the systematics and evolution of the fungi. Molecular and subcellular characters have given us our first view of the true phylogeny of the fungi. The systematic chapters present detailed illustrated treatments of specific fungal groups with the authors' interpretation of the systematics of that group as well as a survey of specific economic, ecological, morphological, ultrastructural, molecular and cultural data. Other chapters, in addition to treating techniques useful in modern mycology, provide the reader with views of the place of the fungi among the Eukaryotes and relationships within the Mycota. Volume VII, Part A, includes an overview of the fungal hierarchy, Pseudomycota, Chytridiomycota, Zygomycota, Ascomycota and their yeasts, and anamorphic states. Volume VII, Part B, includes the Basidiomycota and their yeasts, and chapters on speciation, molecular evolution, preservation, computer techniques, and nomenclature.
