CA1 ACE en contenedores, en septiembre 2002 en Chillán (Chile), en tres sustratos: turba, corteza de pino compostada y una mezcla de 20% tierra de algas, 30% arena y 50% cascarilla de arroz. Se fertirrigó con tres niveles de nitrógeno: 4, 8 y 16 meq L-1, en relación N: P: K de 1:2:1. La tercera formulación, recomendación tipo FAO, tenía relación 1:0,4:1. Se midió a los sustratos propiedades físicas y químicas y a las plantas: emergencia, altura, número de hojas, diámetro de tallo, peso fresco y seco aéreo y radicula, área foliar, materia seca y nitrógeno foliar. Las propiedades medidas a la tierra de algas pura confirman la necesidad de usarla en mezcla. La mezcla utilizada no resultó adecuada para el crecimiento y desarrollo del tomate. Algunos parámetros de crecimiento presentaron interacción entre sustrato y nivel de nitrógeno. A los 42 días después de siembra las características más deseables en plantas se obtuvieron en turba con las soluciones que contenian 8 y 16 meq N L-1.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.

Download or read book Banana Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Download or read book Dietary Supplements and Health written by Gregory R. Bock and published by John Wiley & Sons. This book was released on 2007-08-20 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary supplements can contain a wide variety of ingredients, either singly or in combination, including nutrients, botanicals and 'bioactive components' commonly found in foods. They are marketed and used by consumers for a range of reasons: to enhance "well-being", as traditional medicines, for health promotion or disease risk reduction, and as alternatives or complements to conventional drug therapies. On a global basis, the dietary supplement industry has enjoyed rapid growth, becoming a multi-billion dollar enterprise over the last 10 years. This growth has been associated with significant changes in both the types of products available and the reasons for using these products. In many cases, these changes have occurred without the benefit of a sound scientific basis for evaluating the safety and efficacy of these products under the new conditions of use and frequently the same limited scientific evidence is used, even though current product composition, user populations, purported beneficial effects, and conditions of use may differ significantly from the available evidence or historical usage. This book presents systematic examinations of the scientific data that are available and/or needed to substantiate and evaluate the safety and efficacy of dietary supplements. A series of case studies that are illustrative of the types of scientific challenges that have been encountered in substantiating safety and efficacy for various product types are employed to point out some of the successes but also frustrations that have occurred in recent years. Discussions among presenters and participants identify the lessons learned from these experiences and formulate ideas for improved approaches to identifying research needs and for enhancing the quality and relevance of the scientific evidence available for policy decisions. Dietary Supplements and Health constitutes a useful resource for nutritionists, biochemists, public health researchers and anyone interested in herbal, alternative medicines.
