Book excerpt: Estudos preliminares no que se refere ao explante, tipo e concentrações de reguladores vegetais são necessário para se definir um protocolo de conservação in vitro de germoplasma, bem como garantir a fidelidade na resposta morfogenética. Avaliou-se a influência dos reguladores de crescimento vegetal ácido nafatalenoacético (ANA) e ácido giberélico (AG3) no estiolamento in vitro e posterior regeneração de plantas do abacaxizeiro hídrico PE x SC-60 (Perolera x Smooth Cayenne). Os resultados revelaram que o ANA favoreceu quanto ao estiolamento, números de gemas e diâmetro de haste estiolada, no entanto ele não foi eficiente quanto à resposta organogênica, independentemente da concentração do AG3. Foram testados também os reguladores vegetais benzilaminopurina (BAP) e paclobutrazol (PBZ) sob a taxa de multiplicação in vitro do abacaxizeiro hídrico de PE x SC-60,quando da utilização de hastes estioladas provenientes do meio de cultura MS (Murashige & Skoog,1962)sem adição de reguladores. Verificou-se que o PBZ não foi eficiente na regeneração de brotos, enquanto que a concentração de 0,5mg. L-1 de BAP propocionou uma taxa de multiplicação de 36,5 brotos por explante. Estudou-se ainda o efeito do PBZ no crescimento in vitro do referido hídrico, visando à conservação de germoplasma. Os resultados mostraram a viabilidade de se manter, por um ano, plantas deste hídrico em condições de crescimento reduzido, em ausência total deste regulador ou quando as plantas foram estabelecidas na concentração de 0,5mg. L-1 de PBZ, porém subcultivadas posteriormente para meio sem regulador.

Download or read book Micropropagação e viabilidade de regeneração de variedades silvestres de abacaxi conservadas in vitro written by Marta Taluana Santos Santos and published by . This book was released on 2008 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: O Brasil é o centro de origem e dispersão do abacaxi, abrigando uma importante diversidade genética, incluindo formas silvestres e cultivadas. Essa variabilidades é fundamental, tanto para os programas de melhoramento genético, quanto para a conservação do germoplasma. Por outro lado, parte do êxito nos programas de melhoramento depende muito da eficiência na propagação dos materiais usados como parentais ou dos selecionados. Dessa forma são importantes, tanto o estabelecimento de protocolos de propagação eficientes de variedades silvestres, como ações de conservação de germoplasma. A micropropagação e a conservação in vitro são técnicas de cultura de tecidos com potencial para dar suporte tanto ao melhoramento genético quanto á conservação de germoplasma. Em vista disso o objetivo desse trabalho foi avaliar a eficiência do cultivo de segmentos nodais de genótipos da variedade silvestre Ananas comosus var. ananassoides com vista á micropropagação e conservação in vitro, e avaliar a viabilidade e a posterior taxa de multiplicação de diferentes genótipos de Ananas comosus var. comosus conservados in vitro. Os resultados obtidos de dez genótipos de abacaxi Ananas comosus var. ananassoide (25, 203, 205, 206, 207, 232, 233, 465, 472, e 772) mostraram a eficiência no uso de segmentos nodais para incrementar a micropropagação de genótipos silvestres, sendo que dos dez avaliados o 203 foi o que apresentou o melhor desempenho, tanto na formação de segmentos nodais, como na regeneração de plantas. já a viabilidade dos acessos conservados após um período de quatro meses a um ano de incubação sob condições de crescimento mínimo mostrou que a relação entre o tempo de conservação e o estado fisiológico da planta é resultado de um forte componente genético associado ás condições de cultivo estabelecidas para a conservação in vitro.

Download or read book Environment and Climate-smart Food Production written by Charis M. Galanakis and published by Springer Nature. This book was released on 2021-11-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and food systems, forestry, the marine and the bio-based sectors are at the very heart of the climate change crisis. Evidence on climate change reveals that it will affect farming first, through changes to rainfall regimes, rising temperatures, the variability and seasonality of the climate and the occurrence of more frequent extreme events (heatwaves, droughts, storms and floods). In addition to findings ways to mitigate greenhouse gas emissions, farmers will need to develop farming systems resilient to fluctuating environmental and socioeconomic conditions. It is thus a great challenge to support ambitious climate targets while satisfying the needs for food, feed, bio-based products and energy for a global population projected to reach 10 billion by 2030. Few books on the market integrate environment studies and climate-smart food production. This book fills the knowledge gap by covering all the relevant aspects in one reference: starting with microclimate management, climate change and food systems, and resilience of mixed farming and agroforestry systems, chapters address agricultural soil management, integrated water management in small agricultural catchments, citizen-driven food system approaches in cities, and ICT-enabled agri-food systems. By focusing on the most recent advances in the field while analyzing the potential of already applied practices, this book can serve as a handbook for regulators and researchers looking to understand all aspects of food production and distribution in this changing environment.

Download or read book Conservation and Utilization of Horticultural Genetic Resources written by P.E. Rajasekharan and published by Springer. This book was released on 2019-06-25 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.
