Caracterización cualitativa de frutos de rambutan (Nephelium lappaceum L.), almacenamiento postcosecha y patógenos asociados.
Provedor de dados: Depósito Institucional Abierto de Documentos Digitales del Colegio de Postgraduados (COLPOS DIGITAL )
Autores: Hernández Arenas, Marian Guadalupe.
El rambutan (Nephelium lappaceum L.) es un frutal tropical originario de Asia e introducido a México. Es cultivado principalmente en el estado de Chiapas pero su comercialización es limitada por una corta vida en anaquel, oscurecimiento del pericarpio y enfermedades postcosecha. Los objetivos de este trabajo fueron: 1) caracterizar frutos de cinco selecciones de rambután procedentes del estado de Chiapas; 2) estudiar el efecto de una cera y dos atmósferas modificadas a temperatura ambiente y refrigeración sobre la calidad visual y vida en anaquel de los frutos y 3) identificar el agente causal de la mancha negra del rambutan en postcosecha. Los frutos fueron cosechados entre Junio y Agosto del 2007 y 2008 en Tuxtla Chico, Chiapas. Se realizaron estudios de...

Postharvest longevity of 'BRS Vitória' seedless grapes subjected to cold storage and acibenzolar-S-methyl application
Provedor de dados: Pesquisa Agropecuária Brasileira

Abstract: The objective of this work was to evaluate cold storage periods and postharvest longevity of the seedless table grape 'BRS Vitória' subjected to the application of the disease-resistance inducer acibenzolar-S-methyl (ASM). Bunches were treated or not with 1% ASM, placed individually in plastic clamshell trays and stored in a cold chamber at 2±1ºC, at a high relative humidity, for three periods (30, 45, and 60 days), followed by a 5-day period of shelf life in plastic clamshells, at 22±2ºC. After each storage period, gray mold (Botrytis cinerea) incidence was evaluated, and the physicochemical analysis was performed. A completely randomized design, with four replicates, was used in two 2x3 factorial arrangements: one evaluating ASM application and...

UV-C radiation on fresh fig quality
Provedor de dados: Scientia Agricola
Autores: Usberti,Franciane Colares Souza; Ferraz,Antonio Carlos de Oliveira.
ABSTRACT: Sanitization using chemical agents to reduce the microbiological load on the surface of agricultural products have the drawback of leaving residues. Conversely, physical treatments, such as ultraviolet radiation C (UV-C), are residue-free, non-toxic and environmentally friendly. Ripe figs are perishable, exhibiting an epidermis with low resistance to mechanical treatment, high water content and the ostiole, which is an open door that expedites undesirable microorganism penetration. In this study, the effect of different energy levels of UV-C radiation on the appearance and physico-chemical properties of the figs when stored at 10 °C and 20 °C was evaluated focusing on the technological parameters of the application of radiation. The energy levels...

Potassium permanganate effects on the quality and post-harvest conservation of sapodilla ( Manilkara zapota (L.) P.Royen) fruits under modified atmosphere
Provedor de dados: Acta Agronómica

Abstract Sapodilla (Manilkara zapota (L.) P. Royen) is a climacteric fruit, very perishable, with high metabolic activity, rapid ripening and reduced storage time at room temperature, thus making difficult its commercialization. However, this research aimed to evaluate the effect of potassium permanganate (KMnO4) on the quality and post-harvest conservation of sapodilla fruit under modified atmosphere at room temperature. The sapodilla fruits were harvested when they reached physiological maturity and then accommodated in Styrofoam trays with PVC film coating. Within each package, KMnO4 were placed at different concentrations (0, 0.250, 0.375, and 0.500 g of KMnO4 per kg of fruit, respectively), impregnated in vermiculite. In addition, were kept in storage...
