This book was released on 2005 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: O abacaxizeiro (A. comosus var. comosus) é uma frutífera originária da região sul do Brasil que apresenta paladar agradável e valor nutracêutico atribuído à presença de vitaminas e sais minerais. Mesmo em se tratando de uma cultura de grande demanda no mercado mundial de frutas e de alta rentibilidade, o abacaxi ainda não conseguiu um lugar de destaque no cenário agrícola brasileiro, principalmente em função da fusariose, doença causada pelo fungo Fusarium subglutinans, que pode causar perdas de 30 a 40% na produção da cultura. A obtenção de um mapa genético do abacaxizeiro por meio de marcadores moleculares permite identificar regiões genômicas responsáveis por características da planta e do fruto que sejam de interesse agronômico. No presente trabalho objetivou-se mapear genes de resistência à fusariose em uma população intra-específica, por meio de marcadores moleculares visando identificar marcas moleculares para auxiliar programas de melhoramento genético do abacaxizeiro. A população segregante foi constituída por 179 indivíduos F1RC1, dos quais 119 são provenientes do retrocruzamento de (Perolera x Smooth Cayenne) x Smooth Cayenne e 60 do cruzamento recíproco [Smooth Cayenne x (Perolera x Smooth Cayenne)], em que o híbrido é portador do alelo de resistência Rfs1. Cada indivíduo dessa população foi clonado e inoculado com uma suspensão de esporos obtida de cultura monospórica de F. subglutinans f. sp. ananas, ajustada para 1 x 10[elevado a cinco] conídios/mL, para avaliar a resistência. Por não se saber no início o tipo de herança da resistência e para acessar tanto as bandas com segregação típica RC como F2, cinco indivíduos da progênie foram genotipados com 60 primers RAPD, dos quais 20 amplificaram pelo menos uma banda polimórfica.

Book Synopsis Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes by : A. Ciancio
Download or read book Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes written by A. Ciancio and published by Springer Science & Business Media. This book was released on 2007-12-08 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume of the IMPD series describes aspects related to the most important phytoparasitic nematodes, considering the integration of biological control methods with other management practices and technologies, including the use of predatory nematodes and microbial rhizosphere antagonists. A focus is given on regional issues. A review on nematode management in cotton is integrated by a chapter on management of nematodes on wheat. New technologies are also revised.
Book Synopsis The Palms of the Amazon by : Andrew Henderson
Download or read book The Palms of the Amazon written by Andrew Henderson and published by . This book was released on 1995 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The palms are among the most abundant, diverse, and important families of plants found in the Amazon. Based on extensive field work, this book provides a systematic treatment of all palms that occur naturally in the Amazon region. Each species is exhaustively described with reviews of their distribution, habitat, and ecology. Introductory chapters describe the physical setting of the Amazon region as well as on the biogeography and ecology of the palm family. This first modern treatment of the 135 species of Amazon palms provides a definitive account of their ecology, uses, and biogeography. It will be welcomed by students, teachers, and researchers of botany, ecology, agronomy, and conservation biology.
Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
Book Synopsis Nematode Interactions by : M. Wajid Khan
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.
