    Ajuste de curvas de producción de claveles y mini claveles en una empresa productora y exportadora en la Sabana de Bogotá mediante datos funcionales
    (Universidad del Valle, 2018) Bedoya Dorado, Evelyn; Olaya, Javier; Tovar Rios, Diego Alejandro
    Colombia es uno de los principales productores y exportadores de flores del mundo, ocupando el segundo lugar después de Holanda. Los departamentos de Cundinamarca y Antioquia concentran la mayor producción, con el 72% y 27% respectivamente. Gracias al apoyo del Ministerio de Agricultura y programas de promoción, las exportaciones se han diversificado, aunque Estados Unidos sigue siendo el principal destino, recibiendo el 75% de la producción. En 2016, las exportaciones alcanzaron 1.312 millones de dólares y 235.000 toneladas, destacándose especies como rosa, clavel y crisantemo. En este contexto, la empresa C.I. Flores de Aposentos S.A.S., dedicada a la producción y exportación de claveles y mini claveles, busca mejorar sus modelos de predicción de producción. Actualmente, sus modelos son empíricos y no se ajustan al comportamiento real de los datos; por ello, este trabajo propone ajustar las curvas de producción mediante un modelo estadístico no paramétrico que represente con mayor precisión los índices reales de producción.

    Floriculture in Colombia has great economic and social impact bringing important profit to the sector for more than 40 years. Recently, the hydrangeas flower market have the largest growths in cultivated areas and exported product, but they also have the highest rates of interceptions at the international ports. Even so, few information about the main pests affecting crops, areas or cultivars has been published. This study evaluated the pests captured on hydrangeas’ flowers inspected in a trading company of the Eastern region of Antioquia. A total of 6,272 samples (31,360 flowers), of nine cultivars from 86 farms in six municipalities collected during five months were used. The 8.61 % of the samples had at least one limiting-pest specimen for exportation. The most frequent arthropods were mites, eggs and motile stages, and in less frequency aphids, thrips and slugs. The most affected cultivars were those with blue flowers. The 90 % of the farms (n = 86) had at least one event of interception, although there was no spatial pattern associated with municipality. Our data suggest that the interceptions by quarantine pests were associated with the crop and post-harvest management rather than their geographic location or cultivars. This work provides, for the first time, information of the pests with highest incidence in exporting-type Hydrangeas. Although there is no information about the incidence of hydrangeas pests in the crops, these results could help to identify priority areas and cultivars for inspection and evaluation in the field.
