Available in PDF, EPUB and Kindle. Book excerpt: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10 and 0 or 25 colony forming units per gram of soil in 1991 and 1992, respectively. Plants were sampled destructively over a 4 wk period. Dry weight of foliage, fresh weight of below ground plant material, root length, and root and vascular colonization by V. dahliae were determined. In weeks 3 and 4, change in foliar dry weight in response to the level of one independent variable depended on the level of the other. This interaction between soil water pressure and inoculum density was such that foliar dry weight was reduced in infested compared to noninfested soil at -0.01 MPa but not at other soil water pressures. There were no significant main effect interactions on below ground fresh weight or on root length. There was, however, a main effect of soil water pressure on root length in which length decreased as soil water pressure increased. In both years, colony density in roots (cfu/cm or cfu/g) was reduced at -0.01 MPa compared to lower soil water pressures. Colonization of vascular tissue (cfu/ml stem sap) was significantly reduced at -0.01 MPa compared to lower soil water pressures. Although V. dahliae and soil water pressure at -0.01 MPa interactively reduced foliar growth of plants, there were no corresponding significant increases in population densities of the pathogen in roots or stems.

Download or read book Potato Ecology And modelling of crops under conditions limiting growth written by A.J. Haverkort and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato is the fourth major staple food in the world and is still rapidly gaining importance, especially in the tropics. In May, 1994 the second international potato modelling conference was held in Wageningen, the Netherlands, as a summerschool of the C. T. de Wit Graduate School. The conference was sponsored by DLO, SCRI, SSCR, W AU and the LEB-Fund. Over 80 scientists participated, coming from 16 countries. Of each crop physiological and modelling subject, a leading scientist was requested to write a review of the most recent developments in his or her field. The reviews, with highlights from the authors' own work, are such that the physiological work described is of interest to the modeller and the modelling work to the crop physiologist. Applications of the quantitative approach are also reviewed in the concluding chapters that deal with decision support systems, breeding and agro-ecological zoning. An outstanding point of this book is that both the crop ecology and the modelling of a broad range of biotic and abiotic factors are treated by scientists representing groups which are specialized in the subject. The two related disciplines met during the conference and thus wrote the chapters with each other's interest in mind. The book highlights the limitations for potato growth and development from the viewpoints of both the crop physiologist and the crop-systems analyst.

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.

Download or read book Fungal Wilt Diseases of Plants written by Marshal Mace and published by Elsevier. This book was released on 2012-12-02 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungal Wilt Diseases of Plants focuses on wilt diseases caused by the fungal genera Verticillium, Fusarium, and Ceratocystis. Special attention is given to the interactions of physiological, biochemical, and anatomical factors, as these relate to pathogenesis and mechanisms of disease resistance. Organized into 16 chapters, this book begins with a description, in a historical perspective, of the major research themes in fungal wilt diseases. It then looks into the worldwide status of this plant disease. The three subsequent chapters describe the epidemiology and life cycle of the major fungal wilt pathogens in Fusarium, Verticillium, and Ceratocystis. This book also provides an in-depth view of the genetics and biochemistry of these pathogens; the nature of pathogenesis and the effects of wilt pathogens on host-water relations; and the sources and genetics of host resistance in field and fruit crops, vegetable crops, and shade trees. Other chapters are dedicated to the biochemistry, physiology, and the anatomical aspects of resistance and to the progress in the biological and chemical control of these pathogens. This text will be of great value to graduate students and senior research scientists in plant pathology, physiology, and biochemistry, who are specifically involved in studying wilt diseases and host-parasite interactions. It will provide them the detailed background information needed to supplement their specialized research interests.

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the International Conference on Effects of Crop Rotation on Potato Production in the Temperate Zones. This conference was held in the International Agricultural Centre at Wageningen, The Netherlands, August 14 - 19, 1988, under the auspices of the European Association for Potato Research (EAPR), the Potato Association of America (PAA) and the Dutch National Council for Agricultural Research (NRLO). The length of rotations affect the performance of potato crops and yields are often reduced if rotations are too short. The kinds of crops within a rotation will also affect potato performance, especially those grown in the previous season. It was a major aim of the conference to bring together specialists of various disciplines to examine these determinants of potato yield. The Organizing Committee is glad that all relevant aspects of the theme are highlighted in these proceedings. The contents of the contributions are primarily left to the responsibility of the authors. J. Vos C.D. van Loon G.J. Bollen ORGANIZATION OF THE CONFERENCE The European Association for Potato Research (EAPR) and the Potato Association of America (PAA) nominated representatives in the Conference Committee. PAA was represented by prof. dr E.E. Ewing (Ithaca, USA) and by dr R.E. Thornton (Pullman, USA); EAPR was represented by prof. dr J.C. Holmes (Edinburgh, UK), ir C.D. van Loon (Lelystad, NL), and dr ir J. Vos (chairman; Wageningen, NL).
