Abstract: La variedad de rosal (Rosa hybrida L.) ‘Black Magic’ por sus pétalos aterciopelados de color rojo intenso, es altamente apreciada por los productores del Estado de México debido a su demanda durante todo el año, en particular en fechas pico (14 de febrero, 10 de Mayo y 12 de diciembre). Debido a que su problema principal es el marchitamiento precoz en la fase postcosecha causado por una baja absorción de agua, en este trabajo se evaluaron tres soluciones preservantes con base en 8- citrato de hidroxiquinoleina… Show more

Flower thrips represent a complex of significant quarantine species affecting the cut flower market in Colombia. The aim of this research was to evaluate postharvest treatments using phosphine in conjunction with a plant extract for thrips control and quality control of five cut flower species. Eight treatments were used: six employed a commercial dose of magnesium phosphide as a source of phosphine, one used a double dose and a control group without phosphine application. The first six treatments followed a bi-factorial structure, incorporating three exposure times and the addition of a chili-garlic extract. Thrips control efficacy was evaluated using the Schneider-Orelli index based on field-collected samples. Postharvest quality assessments were conducted on roses, carnations, alstroemerias, chrysanthemums, and hydrangeas over an 18-d period following treatment application. Differences in efficacy were observed between the two locations (the blocking factor). Discrepancies in phosphine efficacy may be related to the variations in populations collected from different crops and locations, both in the departments of Cundinamarca and Antioquia. Variations in magnesium phosphide concentration, both at the commercial dose of 3.4 g m-3 and double this amount (2X) did not produce significant differences in treatment efficacy or flower quality. The use of chili pepper and garlic extract applied by nebulization at 3°C combined with phosphine application also did not significantly affect thrips mortality efficacy. The factor most influencing efficacy improvement was exposure time, as longer time periods led to better thrips control. Furthermore, we found that longer exposure times did not affect visual quality or vase life, assessed through changes in color, physiopathies, and chlorophyll content.

La actividad florícola es una de las principales fuentes de ingresos del Sur del Estado de México, donde la cosecha de la rosa de corte es la más importante debido al valor de la producción generado. Se realiza una revisión sobre el concepto de calidad desde dos enfoques: objetivo y subjetivo; posteriormente se profundiza en los métodos no hipotéticos (subasta experimental y análisis sensorial) para determinar la disponibilidad de pago del consumidor de la rosa de corte. El objetivo de esta investigación es determinar si la percepción de calidad del consumidor influye en la disponibilidad a pagar (DAP) en el consumo de rosa de corte mexicana. En el presente estudio, la DAP de los consumidores se evalúa mediante una subasta experimental. De acuerdo con los resultados, se puede concluir que la disponibilidad a pagar (DAP) hacia la rosa de corte está vinculada a los ingresos de los consumidores y a la percepción de calidad del consumidor de la rose de corte.
