This book was released on 1976 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foi estudado o comportamento com relacao a producao de 16 cultivares de milho. O material genetico foi classificado em cinco grupos, assim discriminados: grupo I, reunindo populacoes, grupo II, reunindo variedades melhoradas (sinteticas) grupo II, reunindo hibridos duplos, grupo IV, reunindo hibridos simples e grupo V, reunindo hibridos intervarietais. Os dados foram obtidos em 16 experimentos, nos anos agricolas de 1974 e 1975, em oito localidades a saber: Santa Ines-MA, Dom Pedro, Codo, Passagem Franca, Teresina-PI, Picos, Piripiri e Elesbao Veloso. Os resultados obtidos revelaram que o cultivar Phoenyx apresenta boa estabilidade de producao, aliada a uma alta produtividade, existindo boa estabilidade de producao, aliada a uma alta produtividade, existindo ainda certa heterose com relacao aos sinteticos paternais (Maya-x e IAC-1-VIII). Verificou-se tambem que o cultivar M-102, Centralmex, Maya-X, IAC-1-VIII e Hmd 7974 mostraram-se com alta capacidade de estabilidade fenotipica de producao, todos com rendimento alto. As variedades melhoradas Centralmex, Maya-x e IAC-1-VIII tiveram producoes semelhantes aos hibridos duplos comerciais usados como testemunha, revelando assim, capacidade em potencial para o melhoramento. Pelo objetivo do presente trabalho, as variedades melhoradas Centralmex e Maya-X externaram boa capacidade fenotipica da producao, com alta produtividade, alem de apresentarem caracteristicas agronomicas desejaveis, de maneira que esta adaptacao vem ao encontro das necessidades da agricultura (...).

This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vinte e cinco cultivares de milho foram avaliadas no ano de 1998 no Estado do Piaui, em nove ambientes, visando conhecer o comportamento e adaptabilidade e a estabilidade dessas cultivares para fins de recomendacao. Utilizou-se o delineamento experimental em blocos ao acaso com tres repeticoes. Foram detectadas, nas analises de variancia conjuntas, diferencas entre as cultivares, os ambientes e um comportamento biconsistente das cultivares frente as variacoes ambientais para as caracteristicas alturas de planta e de espiga, estande de colheita, numero de espigas colhidas e peso de graos. Em virtude da presenca significativa dessa interacao para os pesos de graos, realizou-se a recomendacao de cultivares procurando-se atenuar o efeito dessa interacao atraves da identificacao de cultivares de melhor adaptacao e maior estabilidade de producao, utilizando-se a metodologia proposta por Cruz et al. (1989). A recomendacao de variedades melhoradas e de melhor adaptacao podera contribuir para o aumento da produtividade de milho no Estado do Piaui.

Book Synopsis The Root Causes of Biodiversity Loss by : Alexander Wood
Download or read book The Root Causes of Biodiversity Loss written by Alexander Wood and published by Routledge. This book was released on 2013-11-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.

Book Synopsis Advances in Fungal Biotechnology for Industry, Agriculture, and Medicine by : Jan S. Tkacz
Download or read book Advances in Fungal Biotechnology for Industry, Agriculture, and Medicine written by Jan S. Tkacz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, filamentous fungi have grown in commercial importance not only in the food industry but also as sources of pharmaceutical agents for the treatment of infectious and metabolic diseases and of specialty proteins and enzymes used to process foods, fortify detergents, and perform biotransformations. The commercial impact of molds is also measured on a negative scale since some of these organisms are significant as pathogens of crop plants, agents of food spoilage, and sources of toxic and carcinogenic compounds. Recent advances in the molecular genetics of filamentous fungi are finding increased application in the pharmaceutical, agricultural, and enzyme industries, and this trend promises to continue as the genomics of fungi is explored and new techniques to speed genetic manipulation become available. This volume focuses on the filamentous fungi and highlights the advances of the past decade, both in methodology and in the understanding of genomic organization and regulation of gene and pathway expression.
Book Synopsis Precious Heritage by : Bruce A. Stein
Download or read book Precious Heritage written by Bruce A. Stein and published by Oxford University Press. This book was released on 2000-03-16 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
Book Synopsis Innovation in Brazil by : Elisabeth B. Reynolds
Download or read book Innovation in Brazil written by Elisabeth B. Reynolds and published by Routledge. This book was released on 2019-03-15 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 2000s, state-led and innovation-focused strategies have characterized the approach to development pursued in countries around the world, such as China, India, and South Korea. Brazil, the largest and most industrialized economy in Latin America, demonstrates both the opportunities and challenges of this approach. Over the course of nearly 20 years, the Brazilian government enacted various policies and programs designed to strengthen the country’s capacity to innovate. It increased spending on science and technology, encouraged greater collaboration between industry and universities, and fostered the creation of new institutions whose primary aim was to facilitate greater private research and development (R&D) spending. In this book, the editors unite a diverse array of empirical contributions around a few key themes, including public policies, institutions and innovation ecosystems, and firms and industries, that collectively make the case for a new, forward-looking innovation agenda aimed at addressing persistent challenges and exploiting emerging opportunities in Brazil. Its conclusions offer valuable lessons for other developing and emerging economies seeking to accelerate innovation and growth in the modern age. With its interdisciplinary and wide-ranging contribution to the study of innovation, as well as attention to broader policy implications, this book will appeal to scholars and professionals alike.

Book excerpt: Sugarcane exhibits all the major characteristics of a promising bioenergy crop including high biomass yield, C4 photosynthetic system, perennial nature, and ratooning ability. Being the largest agricultural commodity of the world with respect to total production, sugarcane biomass is abundantly available. Brazil has already become a sugarcane biofuels centered economy while Thailand, Colombia, and South Africa are also significantly exploiting this energy source. Other major cane producers include India, China, Pakistan, Mexico, Australia, Indonesia, and the United States. It has been projected that sugarcane biofuels will be playing extremely important role in world’s energy matrix in recent future. This book analyzes the significance, applications, achievements, and future avenues of biofuels and bioenergy production from sugarcane, in top cane growing countries around the globe. Moreover, we also evaluate the barriers and areas of improvement for targeting efficient, sustainable, and cost-effective biofuels from sugarcane to meet the world’s energy needs and combat the climate change.
