E. Mora Eguiguren and published by . This book was released on 1978 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este trabajo se realizo con el proposito de evaluar la indicencia (porcentaje de hojas enfermas) y la severidad (porcentaje de area foliar enferma) de cinco enfermedades del maiz (Zea mays L.) y dos del frijol comun (Phaseolus vulgaris L.). El maiz y el frijol comun se cultivan en dos sistemas de cultivos (monocultivos y asociados) durante la estacion seca. En la estacion lluvios se cultivo solo maiz, en las mismas parcelas que se habia cultivado frijol y/o maiz. Las rotaciones resultantes se cultivaron en cuatro tipos diferentes de labranzas de suelo, que incluian dos tipos de cobertura con residuos de vegetacion, no labranza y cobertura vegetal y labranza tradicional (labor mecanizada). Los datos de los indices de Incidencia y severidad de las enfermedades de maiz y frijol se obtivieron de mediciones periodicas, realizadas a partir de diciembro de 1976 y finalizadas en noviembro de 1977, en el Centro Agronomico Tropical de Investigacion y Ensenanza, Turrialba, Costa Rica. Segun los resultados que se obtuvieron, las enfermedades del maiz que mayor area dfoliar afectaron en orden de importancia decreciente fueron: tizon de la hoja (Helminthosporium turcicum) en el periodo seco y mancha Diplodia macrospora) en el periodo lluvioso. Luego considerado los dos periodos experimentaes siguen: roya tropical (Physopella zeae), roya comun (Puccinia polysora) y mancha de asfalto (Phyllachora maydis). Estas tres ultimas enfermedades presentaron mayor ataque en la epoca lluviosa. Las enfermedades de mayor importancia (...).

Book Synopsis Efecto de la poda en la produccion de semilla de frijol (Phaseolus vulgaris L.) de habito indeterminado, cv. Flor de Mayo (X-16441). by : Candido Lopez Castañeda
Download or read book Efecto de la poda en la produccion de semilla de frijol (Phaseolus vulgaris L.) de habito indeterminado, cv. Flor de Mayo (X-16441). written by Candido Lopez Castañeda and published by . This book was released on 1982 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: El frijol de habito indeterminado cv. Flor de Mayo (X-16441), cuando crece espaldera en clima templado y durante el verano ramifica profusamente y exhibe un crescimento exuberante llegando a alcanzar mas de 4m de altura, bajo estas condiciones su cultivos es impractico y se produce un excesivo autosombreo. Probablemente la planta sea poco eficiente para la produccion de semillas. El presente trabajo tuvo como objetivo estudiar el efecto de 1a poda de ramas o de yemas en la eficiencia de la planta para producir semillas. Se realizaron tres experimentos (Exp I, Exp II y III) de poda de la parte aerea (ramas o yemas), en plantas aisladas del cv. Flor de Mayo (X-16441) que se desarrollaron sobre una espaldera en condiciones de campo. Las plantas se establecieron por trasplanta 20 dias despues de la siembra a 3m entre plantas y 2.4m entre surcos, dispuestas en tresbolollo. El tallo principal y las ramificaciones de las plantas se guiaron con hilaza de algodon sobre una espalcera de tipo tripies modificado favoreciendo el desarrollo horizontal y vertical. Los tratamientos de poda de ramas y de yemas se disenaron combinando poda del tallo principal, ramas primarias y ramas secundarias en base al numero de nudos, con niveles de 9 y 17; 0,10 y 20 y 0,10, 10 nudos, respectivamnete. Se uso un deseno de bloques al azar con 3 repeticiones en donde cada planta aislada constituyo la unidad experimental. La poda de ramas se inicio a los 79 dias en el Exp I y 74 dias en el Exp II, cuando aparecio el primer boton floral. La poda de yemas (Exp III) se inicio durante la fase vegetativa, 48 dias despues de la siembra. Resultados: Se encontro que tanto la poda de ramas como de yemas afecto significativamente la altura de planta y la edad a la madurez fisiologica, reduciendo el porte de la plantas y retardando su maduracion. La poda de yemas retardo significativamnete la edad al final de la floracion. Tanto en poda de ramas como de yemas se modifico la morfologia de la planta influyendo en la distribucion del rendimiento y sus componentes en las distintas categorias de ramas. Por otro lado no fueron afectados, el rendimiento final y sus componentes, la abscision de estructuras reproductivas, el aborto de semillas y de rudimentos seminales, el numero de vainas vanas a la cosecha la acumulacion de materia seca en hojas, tallos y pericarpoi y la eficiencia de la planta para la produccion de semillas. De acuerdo con las evidencias obtenidas, la poda tanto de ramas como de yemas no afecto la mayoria de las caracteristicas de la planta incluyendo la eficiencia de esta para producir semillas, a excepcion de las edades al final de floracion y a la madurez fisiologica asi como la altura de planta. La poda tanto de ramas como de yemas permitio obtener fenotipos de menor porte que la planta intacta, pero sin lograr aumentar su eficiencia en la produccion de semillas.

Book Synopsis Handbook of Food Engineering Practice by : Kenneth J. Valentas
Download or read book Handbook of Food Engineering Practice written by Kenneth J. Valentas and published by CRC Press. This book was released on 1997-07-23 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food engineering has become increasingly important in the food industry over the years, as food engineers play a key role in developing new food products and improved manufacturing processes. While other textbooks have covered some aspects of this emerging field, this is the first applications-oriented handbook to cover food engineering processes and manufacturing techniques. A major portion of Handbook of Food Engineering Practice is devoted to defining and explaining essential food operations such as pumping systems, food preservation, and sterilization, as well as freezing and drying. Membranes and evaporator systems and packaging materials and their properties are examined as well. The handbook provides information on how to design accelerated storage studies and determine the temperature tolerance of foods, both of which are important in predicting shelf life. The book also examines the importance of physical and rheological properties of foods, with a special look at the rheology of dough and the design of processing systems for the manufacture of dough. The final third of the book provides useful supporting material that applies to all of the previously discussed unit operations, including cost/profit analysis methods, simulation procedures, sanitary guidelines, and process controller design. The book also includes a survey of food chemistry, a critical area of science for food engineers.

Download or read book Polymer Permeability written by J. Comyn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers are permeable, whilst ceramics, glasses and metals are gener ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.
