Book Synopsis Caracterização agronômica e morfológica de genótipos de gergelim by : T. R. Araújo
Download or read book Caracterização agronômica e morfológica de genótipos de gergelim written by T. R. Araújo and published by . This book was released on 2008 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: O gergelim (Sesamum indicum L.) é um vegetal que apresenta ampla adaptabilidade, sendo encontrada em regiões de clima tropical, subtropical e em zonas temperadas. O conhecimento e a quantificação da diversidade genética entre genótipos são de grande importância para o melhoramento do gergelim, tendo em vista a ausência de informações genéticas sobre a maioria do germoplasma disponível. Este trabalho teve por objetivo proceder a uma caracterização dos acessos de gergelim disponíveis da coleção de germoplasma da Embrapa Algodão, baseada em dados morfológicos e agronômicos. Para a realização desse trabalho, foi conduzido um ensaio com genótipos oriundos do BAG do gergelim, que foram semeados e avaliados na Estação Experimental de Veludo, em Itaporanga, PB, sob regime de irrigação. Os dados morfológicos e agronômicos foram obtidos de acordo com uma tabela de descritores. Para análise dos dados foram utilizados procedimentos multivariados hierárquico UPGMA e otimização de Tocher. Para obtenção da matriz de distância foi utilizado o complemento aritmético do coeficiente de Cole-Rodger. A representação gráfica simplificada das distâncias foi feita através de um dendrograma obtido pelo método UPGMA. Concluí-se que genótipos mais divergentes foram BRA 28151 e 24414 e os mais similares foram BRA 2879 E BRA 27855. Houve a variabilidade dos acessos avaliados para fins de obtenção de genótipos superiores com características de produtividade, número de frutos por planta, comprimento do fruto, cor das sementes, ciclo de maturação e número de ramificações laterais que podem ser usadas na seleção de genótipos superiores para o melhoramento genético da espécie. Dentre os acessos, os genótipos BRA 28771, BRA 28401 destacaram-se com alto potencial para produção de sementes.

Book Synopsis Caracterização da diversidade de gergelim por marcadores RAPD. by : A. L. Diniz
Download or read book Caracterização da diversidade de gergelim por marcadores RAPD. written by A. L. Diniz and published by . This book was released on 2008 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: O gergelim (Sesamum indicum L.) apresenta centenas de variedades e linhagens com ampla variação de caracteres, dos quais a deiscência dos frutos recebe destaque atualmente. Marcadores moleculares têm sido utilizados de várias formas na análise genética e em programas de melhoramento das espécies. Este trabalho objetivou caracterizar a diversidade genética de acessos de gergelim por marcadores RAPD, agrupar os acessos avaliados de acordo com o grau de similaridade genética entre eles e identificar, pelo menos, uma marca molecular associada à característica de indeiscência dos frutos. Para tanto, foram utilizados 100 acessos da coleção de germoplasma de gergelim da Embrapa Algodão. A extração do DNA e a amplificação de fragmentos polimórficos por PCR, usando primers RAPD para análise da diversidade genética, seguiram metodologias do protocolo CTAB, com modificações. Cada produto de amplificação do PCR foi considerado um marcador RAPD, os quais foram visualizados com presença ou ausência de bandas em um gel de eletroforese. Os acessos foram agrupados pelo método hierárquico aglomerativo da média aritmética entre pares não ponderados (UPGMA) e a representação simplificada das distâncias genéticas foi feita através de um dendrograma. Todos os genótipos com frutos indeiscentes foram comparados a uma cultivar deiscente, para se identificar uma marca relacionada àquela característica. A partir de 47 primers, foi gerado um total de 130 bandas polimórficas, as quais foram utilizadas no cálculo das distâncias genéticas e na construção do dendrograma. Os genótipos de maior similaridade genética correspondeu aos pares 18-19 e 53-54, ambos com divergência aproximada de 0,08. A maior divergência detectada ocorreu entre os genótipos 18 e 69. Apesar do agrupamento da maioria dos acessos com características de indeiscência, a distribuição dos genótipos aparentemente não se mostrou diretamente associada a tal característica, fato provavelmente relacionado ao caráter aleatório do marcador utilizado. Entretanto, polimorfismo foi detectado entre genótipos indeiscentes e a testemunha utilizada, tornando-se possível relacionar uma marca que provavelmente esteja associada a tal característica. Os marcadores RAPD mostraram-se eficientes para detectar polimorfismo em gergelim, podendo ser utilizados como um poderoso instrumento na obtenção de informações úteis para o manejo de coleções de germoplasma e para o direcionamento de programas de melhoramento genético.
Download or read book Animal Nutrition written by Philip Hynd and published by CSIRO PUBLISHING. This book was released on 2019-11-01 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrition is the key driver of animal health, welfare and production. In agriculture, nutrition is crucial to meet increasing global demands for animal protein and consumer demands for cheaper meat, milk and eggs and higher standards of animal welfare. For companion animals, good nutrition is essential for quality and length of life. Animal Nutrition examines the science behind the nutrition and feeding of the major domesticated animal species: sheep, beef cattle, dairy cattle, deer, goats, pigs, poultry, camelids, horses, dogs and cats. It includes introductory chapters on digestion and feeding standards, followed by chapters on each animal, containing information on digestive anatomy and physiology, evidence-based nutrition and feeding requirements, and common nutritional and metabolic diseases. Clear diagrams, tables and breakout boxes make this text readily understandable and it will be of value to tertiary students and to practising veterinarians, livestock consultants, producers and nutritionists.
Book Synopsis Age and Gender Considerations in Psychiatric Diagnosis by : William E. Narrow
Download or read book Age and Gender Considerations in Psychiatric Diagnosis written by William E. Narrow and published by American Psychiatric Pub. This book was released on 2008-05-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to help identify major gaps in our knowledge of how gender and age affect psychiatric diagnoses and to stimulate much-needed research to fill these gaps, Age and Gender Considerations in Psychiatric Diagnosis serves as both a valuable short-term source for the DSM-V Task Force and its disorder-specific workgroups, and a long-term guide for future studies that will contribute to revised psychiatric classifications in these three areas. Here, 47 experts present findings in three areas of psychiatric research that historically have been neglected but rightfully have received increasing attention in recent years and thus are worthy of investigation into their clinical features, etiology, and course: 1. Significant gender differences in prevalence, symptom profiles, and risk factors for mental disorders, including neurodevelopmental, neurophysiological, and environmental factors for men and women that cut across diagnostic categories-for example, the critical importance of gender in how psychiatric illness develops and presents; DSM's approach to gender to date; and relevant research findings and gaps in the epidemiology, etiology, and pathophysiology of disorders and the gender-related expression of psychopathology, including the controversial and complex question of whether DSM should have different diagnostic criteria for men and women. 2. Mental disorders in infancy and early childhood, including diagnosis and measurement of psychopathology; PTSD and social and cognitive factors related to the experience of stress; reactive attachment disorder (unique in part because of its specificity to early childhood); mood and anxiety disorders and difficulties in diagnosis; sleep disorders, including two new disorders, Night-Waking Dysomnia and Sleep-Onset Dysomnia; feeding disorders, including the need to address overeating and overfeeding (especially given the alleged U.S. epidemic of obesity); early childhood manifestations of behavior disorders; and early symptoms and diagnosis of autism. 3. Mental disorders in the elderly, such as dementia and depression, once considered normal consequences of aging but now understood to represent mental disorders, including the need to identify specific brain structure abnormalities, biomarkers, and the many contributing biological, psychosocial, and environmental factors of mental illness in late life and to understand their roles in the elderly to better diagnose and monitor disease progression. Written for clinicians and researchers alike, this thought-provoking compendium contributes critical information that helps enhance our understanding of the causes of mental disorders, develop effective preventive and treatment interventions, and inform future editions of DSM and ICD.

Book Synopsis A General Theory of Magic by : Marcel Mauss
Download or read book A General Theory of Magic written by Marcel Mauss and published by Routledge. This book was released on 2005-07-05 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: First written by Marcel Mauss and Henri Humbert in 1902, A General Theory of Magic gained a wide new readership when republished by Mauss in 1950. As a study of magic in 'primitive' societies and its survival today in our thoughts and social actions, it represents what Claude Lévi-Strauss called, in an introduction to that edition, the astonishing modernity of the mind of one of the century's greatest thinkers. The book offers a fascinating snapshot of magic throughout various cultures as well as deep sociological and religious insights still very much relevant today. At a period when art, magic and science appear to be crossing paths once again, A General Theory of Magic presents itself as a classic for our times.
