Book Synopsis Diversidade genética em cultivares brasileiras de soja [Glycine max (L.) Merrill] baseada em marcadores microssatélites by : Regina Helena Geribello Priolli
Download or read book Diversidade genética em cultivares brasileiras de soja [Glycine max (L.) Merrill] baseada em marcadores microssatélites written by Regina Helena Geribello Priolli and published by . This book was released on 2002 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Os marcadores microssatélites ou SSR (Simple Sequence Repeat) têm se constituído em excelentes ferramentas na identificação de cultivares, análises genealógicas e estimativas das distâncias genéticas entre organismos. As cultivares de soja têm sido caracterizadas principalmente por descritores morfológicos e bioquímicos. Esses descritores, entretanto, não têm sido suficientes para caracterizar o grande número de cultivares passíveis de proteção, proporcionado pela Lei Brasileira de Proteção de Cultivares. A fim de se estabelecer novos descritores para cultivares de soja, foram estudados alelos de doze locos SSR, dos quais foram estimadas as amplitudes de variação de tamanho, assim como as respectivas freqüências, num grupo de 186 cultivares de soja brasileiras. Em média, 5,3 alelos por loco foram encontrados, com uma diversidade genética média de 0,64 ł 0,12. Esses locos foram utilizados para distinguir grupos morfologicamente similares apresentando coeficiente de similaridade média de 0,46 e estabeleceram 184 perfis nas 186 cultivares. Um dendrograma foi delineado baseado no perfil dos locos SSR e concordou com as informações da genealogia das cultivares.
Book Synopsis Heranca de periodo juvenil longo em soja (Glycine max (L.) Merrill) estimado sob condicoes de dias curtos by : V.C. Pipolo

This book was released on 1996 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com o objetivo de somar conhecimentos que possibilitem explorar a variabilidade genetica e servir de suporte para o desenvolvimento de cultivares de soja (Glycine max (L.) Merrill) adaptadas a condicoes de dias curtos, foi realizado estudo da heranca da caracteristica periodo juvenil (PJL) condicionado pelo efeito complementar da recombinacao de genes entre cultivares de florescimento classico. Foram realizados dois estudos. No primeiro estudou-se o controle genetico do carater PJL na cultivar MG/BR-22 (Garimpo). Quatro cultivares de florescimento classico, isto e que florescem precocemente, (Parana, Bossier, Bragg e Davis) foram cruzadas entre si e com MG/BR-22 (Garimpo). No segundo, estudou-se o tipo de acao genica que condiciona PJL. na linhagem BR80-6778. Esses estudos foram conduzidos em condicoes de dias curtos (semeadura s antecipadas), em casa-de-vegetacao e campo, na area experimental da EMBRAPA - Centro Nacional de Pesquisa de Soja, Londrina, PR, localizado a 23o 22' de latitude sul. Avaliou-se diariamente o florescimento dos parentais e das populacoes F1, F2 e F3. Os dados obtidos foram agrupados em classes baseando-se na media, desvio padrao e amplitude de variacao. As condicoes de temperatura mais elevadas ocorridas no ambiente de casa de vegetacao contribuiu para a reducao do periodo vegetativo, comparativamente ao ambiente de campo. A condicao de plantio antecipado (setembro/ a meados de outubro) foi efetiva para evidenciar a caracteristicas PJL. As proporcoes genotipicas de 15:1 plantas precoce: plantas com PJL na populacao F2 e 9:6:1 para a populacao F3 observadas na combinacao Parana x Bossier caracterizam um caso de interacao digenica com efeito epistatico duplicado recessivo para o carater PJL. A segregacao da populacao F2 do cruzamento Parana x MG/BR-22 (Garimpo) resultou na proporcao esperada de 3:1, indicando que as cultivares MG/BR-22 (garimpo) e Parana diferem em um unico par de genes. De maneiro semelhante, no cruzamento Bossier x MG/BR-22 (Garimpo) a segregacao na propocao de 3:1 foi indicativa de que ambas cultivares diferem para o numero de dias para o florescimento em um locus genico. A cultivar Davis possue o mesmo gene para PJL. que a cultivar Parana, j 2j 2. A segregacao de F2 do cruzamento da cultivar Bragg, de florescimento classico, com MG/BR-22 (Garimpo) seguiu na proporcao de 15:1 indicando que essas cultivares diferem no florescimento para dois loci genicos. A linhagem BR 80-6778 compartilha um par de genes com a cultivar Parana, que quando em associacao com o par de alelos recessivos J 4J 4 retardam o florescimento em condicoes de dias curtos. Conclui-se dessa pesquisa que existem tres pares de genes condicionando a caracteristicas de periodo juvenil longo em condicoes de dias curtos. Foram atribuidas as seguintes constituicoes genotipicas para as cultivares Parana (j 2j 2J 3J 3J 4J 4), Bossier (J 2J 2j 3j 37 4J 4), MG/BR-22 (Garimpo) (j 2j 2j 3j 3j J 4J 4) e BR80-6778 (j 2j 2J 3J 3j 4j 4). A recombinacao dos genes j 2j 2j 3j 3 e j 2j 2j 3j 3j 4j 4 tem efeito pronunciado na manifestacao do carater. Isoladamente, com um unico locus em homozigose recessiva nao e suficiente para condicionar PJL.

Liedgens and published by . This book was released on 1993 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: O crescimento da planta de soja (Glycine max L. Merrrill, cultivar IAC-15). foi estudado em duas epocas de plantio. o estudo envolveu o detalhamento ao nivel da planta, dos ramos e das folhas. o crescimento tembem foi avaliado em termos de duas escalas de tempo a cronologia e baseada no indice de plastochron da planta ou do ramo. Na caracterizacao quantitativa do crescimento, foi a valiada a utilidade dos modelos matematicos definidos pelas equacoes de Richards e polinomial exponencial cubica. o crescimento das plnatas no periodo de cultivo tradicional (novembro). A diferenca foi atribuida a um periodo mais longo de desenvolvimento com condicoes ambientais mais favoraveis. o indice de [lantochron produziu resultados mais consistente que o tempo cronologico, embora a sua utilidade esteja limitada a fase de desenvolvimento vegetativo das plantas. Baseado nos coeficientes de determinacao e na analise de residuos, tanto a equacao de Richards quanto a equacao polinomial cubica tendeu a ser para os dados de planta e de ramos individuais, ao passo que a equacao de Richards determinou melhores resultados para os dados foliares. Devido a melhor correspondencia de seus parametros a realidade. biologica, a equacao de Richards deve ser usada preferencialmente. A ocorrencia de instabilidades matematico-estatisticas e de elevadas para se estimativas dos seu parametros em diversas situacoes, exigem, contudo, uma avaliacao caso a caso dos resultados.

Book Synopsis Ecologically Based Pest Management by : National Research Council
Download or read book Ecologically Based Pest Management written by National Research Council and published by National Academies Press. This book was released on 1996-03-21 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread use of broad-spectrum chemical pesticides has revolutionized pest management. But there is growing concern about environmental contamination and human health risksâ€"and continuing frustration over the ability of pests to develop resistance to pesticides. In Ecologically Based Pest Management, an expert committee advocates the sweeping adoption of ecologically based pest management (EBPM) that promotes both agricultural productivity and a balanced ecosystem. This volume offers a vision and strategies for creating a solid, comprehensive knowledge base to support a pest management system that incorporates ecosystem processes supplemented by a continuum of inputsâ€"biological organisms, products, cultivars, and cultural controls. The result will be safe, profitable, and durable pest management strategies. The book evaluates the feasibility of EBPM and examines how best to move beyond optimal examples into the mainstream of agriculture. The committee stresses the need for information, identifies research priorities in the biological as well as socioeconomic realm, and suggests institutional structures for a multidisciplinary research effort. Ecologically Based Pest Management addresses risk assessment, risk management, and public oversight of EBPM. The volume also overviews the history of pest managementâ€"from the use of sulfur compounds in 1000 B.C. to the emergence of transgenic technology. Ecologically Based Pest Management will be vitally important to the agrichemical industry; policymakers, regulators, and scientists in agriculture and forestry; biologists, researchers, and environmental advocates; and interested growers.

Book Synopsis Enhancing Biological Control by : Charles Hammond Pickett
Download or read book Enhancing Biological Control written by Charles Hammond Pickett and published by Univ of California Press. This book was released on 1998 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past ten years an increasing number of field entomologists and farmers have recognized that conservation of natural enemies is important to effective biological control in many agricultural systems. This collection addresses an important gap in the biological control literature by providing the first comprehensive summary of recent findings on habitat manipulation to control pests. Enhancing Biological Control includes contributions from experts around the world: the United States, Finland, Germany, Great Britain, People's Republic of China, and Switzerland. Chapters cover habitat modification in such areas as fields, orchards, or vineyards, and along or near the perimeters of fields, including hedges or other uncultivated areas. Generalist and specialist natural enemies are described in full, as are theoretical and practical issues. Experimental designs for studying enhancement come into play, and the editors include a modeling study that explores how the dispersal of natural enemies interacts with the positioning of refuges. This volume is an invaluable source of information to researchers, progressive farmers, and agricultural consultants.
