Available in PDF, EPUB and Kindle. Book excerpt: Este libro analiza los aspectos más importantes a tener en cuenta a la hora de llevar a cabo el injerto, la poda y el aclareo en las plantaciones frutales. El injerto es una técnica de multiplicación vegetativa muy utilizada en fruticultura, ya que combina individuos distintos que funcionan como una única planta. Esto permite disponer de plantas que se adapten a determinadas condiciones edafoclimáticas, y a exigencias comerciales o de manejo del cultivo. Además, posibilita la restauración de partes de la planta dañadas y el cambio de una variedad por otra en un árbol ya establecido. Por su parte, la poda es una técnica de cultivo que se realiza de forma habitual en los frutales, con el fin de proporcionar las condiciones óptimas de desarrollo de la planta, para conseguir una producción máxima de frutos de calidad. A través de los distintos tipos de poda, se logrará formar los árboles desde su plantación, organizando y distribuyendo las ramas para que se optimice la captación de luz solar por las hojas, mantener los árboles libres de elementos indeseables, promover una buena productividad de la planta y prolongarla a lo largo del tiempo, así como renovar, cuando sea necesario, determinadas partes del árbol que se han envejecido o dañado. Con el objetivo de mejorar la calidad en la fruta producida, el aclareo de frutos es una operación de cultivo que resulta fundamental en algunas especies en las que el calibre del fruto y sus características organolépticas repercuten en el precio de venta de la fruta. Esta técnica consiste en eliminar de forma manual, mecánica o química, parte de las flores abiertas o de los frutos cuajados, para disminuir la competencia por los nutrientes entre los frutos que van a desarrollarse, lo que repercutiría negativamente en su tamaño y calidad en recolección.

Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Download or read book Sterile Insect Technique written by Victor A. Dyck and published by CRC Press. This book was released on 2021-01-06 with total page 1493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

Download or read book Maya Subsistence written by Kent V. Flannery and published by Academic Press. This book was released on 1982-02-28 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maya Subsistence: Studies in Memory of Dennis E. Puleston presents studies on the history and development of Maya subsistence in honor of Maya archaeologist Dennis E. Puleston (1940-1978). The discussions are organized around four themes: ecological models for early Maya adaptations; archaeological investigations of Pre-classic and classic Maya subsistence; contributions of geography and soil science to an understanding of ancient Maya subsistence; and Maya subsistence in the post-classic, colonial, and modern eras. Comprised of 15 chapters, this book begins with an analysis of Puleston's career and a review of the history of inquiry into Maya subsistence. Maya subsistence from the earliest Pre-classic period up to the present day is then examined, with emphasis on agriculture, hunting, wild plant collecting, animal husbandry, and trade. In particular, cultural development in the Valley of Guatemala from 1500 B.C. to the Spanish Conquest is discussed, along with the resources of the tropical lowlands and actual prehistoric cornfields miraculously preserved by volcanic ashfall in El Salvador. The book also presents evidence for Maya soil and water conservation over the entire area from Yucatan to Chiapas and central Guatemala, and looks at the traditional role of women and animals in lowland Maya economy. This monograph will be of interest to archaeologists and anthropologists.
