El trabajo tuvo como objetivo evaluar la cinética de hidratación del frijol (Phaseolus vulgaris), variedad Pinto, mediante la técnica de imágenes hiperespectrales (IH).

The study aimed to evaluate the precision and accuracy of equipment that determine the quality of sheep fibres. The equipment used (total = 15) were Sirolan Laserscan, OFDA 2000, Minifiber EC and Fiber EC, belonging to nine laboratories in Peru (n=7) and Argentina (n=2). The mean values of the mean diameter fibre (MDF) were determined in relation to the tolerance limits given by IWTO 12 and IWTO 47, using samples of fibres with known diameters. The accuracy was determined from the average obtained from the subsamples minus the actual value of the samples and the precision was evaluated by the standard deviation of the repetitions. Dunnett's multiple comparisons method was used for precision and accuracy. The results showed that the equipment coded as B and C in laboratories 4 and 8 were the most accurate, while equipment B and D in laboratories 5 and 8 shoed the highest precision. Six of...

La papa (Solanum tuberosum) es el cuarto producto más consumido en el mundo. En países en vías de desarrollo, se viene trabajando en la adopción de tecnologías que incrementen la productividad y mejoren la rentabilidad de los pequeños productores; por lo que el acceso a semillas de alta calidad y de bajo costo, puede ser una adecuada alternativa. El objetivo fue comparar el comportamiento productivo y la viabilidad económica de dos sistemas de producción de semilla pre básica a partir de cultivo in vitro de S. tuberosum var. Huayro. Para ello, en condiciones de invernadero, se instalaron dos módulos experimentales, uno convencional y otro hidropónico, con densidades de 25 plantas/m2. Se calculó el peso y cantidad de tuberculillos por planta, además de la rentabilidad de cada tecnología. Aunque bajo el sistema convencional se obtuvo tuberculillos con mayor peso promedio (2...

Este trabajo de investigación tuvo como objetivo evaluar el efecto del pH, tiempo y temperatura de pasteurización de una bebida de extractos de mashua morada (Tropaoelum tuberosum Ruíz y Pavón) en su capacidad antioxidante, contenido de polifenoles totales, flavonoides, antocianinas y su aceptabilidad general.

This study addressed multi-product optimization in Cedrelinga cateniformis plantations in the Peruvian Amazon, aiming to maximize volumetric yields of logs and sawn lumber. Data from seven plantations of different ages and types, established on degraded land, were analyzed by using ten stem profile models to predict taper and optimize wood use. In addition, the structure of each plantation was evaluated using diameter distributions and height–diameter ratios; log and sawn timber production was optimized using SigmaE 2.0 software. The Garay model proved most effective, providing high predictive accuracy (adjusted R2 values up to 0.963) and biological realism. Marked differences in volumetric yield were observed between plantations: older and more widely spaced plantations produced higher timber volumes. Logs of optimal length (1.83–3.05 m) and larger dimension wood (e.g., 25.40 × 5.0...
