The natural pollination in yellow passion fruit (Passiflora edulis f. flavicarpa Degener) as a reproductive and ecosystem service.

The goal of this research was to study the mechanism of pollination in the yellow passion fruit and to identify natural pollinators of importance. The study was carried out in 2010-2011 in the Palestina (Caldas) to 1050 masl, by performing five treatments of pollination: natural (P.N), hand pollinat...

La polinización natural en el maracuyá (Passiflora edulis f. flavicarpa Degener) como un servicio reproductivo y ecosistémico. Arias Suárez, Juan Carlos Ocampo Pérez, John Alberto Urrea Gómez, Ramiro The goal of this research was to study the mechanism of pollination in the yellow passion fruit and to identify natural pollinators of importance. The study was carried out in 2010-2011 in the Palestina (Caldas) to 1050 masl, by performing five treatments of pollination: natural (P.N), hand pollination (P.M.D), spontaneous and assisted self-pollination (A.P, A.P.E.) and geitonogamy/autogamy (G) in 48 accessions of yellow passion fruit. The results showed significative differences between treatments, the highest percentage of set fruit (88%) was observed during P.N carried by bumblebees from genus Xylocopa spp, followed by P.M.D. (60%). In contrast self-pollination treatments (A.P.E, A.P, G) achieved only a 3% set fruit. Likewise, the P.N showed the highest fruit weight average (203 g), and the highest flesh to seed ratio (47%), followed closely by P.M.D (187.5 g and 44.7%, respectively). The activity and effectiveness of pollinators showed a correlation with the maximum daytime temperature (r=0.69), solar irradiance (r=0.56) and relative humidity (r=0.64). However, the highest percentage of fruiting was achieved when the first two environmental variables decreased simultaneously below 26°C and three hours per day less. El objetivo de esta investigación fue estudiar los mecanismos de la polinización en el cultivo del maracuyá y la importancia de los polinizadores naturales. El estudio se realizó en los años 2010–2011, en el municipio de Palestina, Caldas, Colombia a 1050 msnm. Se emplearon cinco tratamientos de polinización: natural (P.N), manual dirigida (P.M.D), autopolinización manual y espontánea (A.P, A.P.E) y geitonogamia (G), en 48 accesiones de maracuyá. Los resultados mostraron diferencias significativas entre tratamientos, la P.N realizada por abejorros del género Xylocopa spp. obtuvo el mayor porcentaje de frutos formados (88%), seguido por P.M.D (60%), y solo un 3% en los tratamientos de autopolinización (A.P.E, A.P, G). De igual manera, la P.N presentó mayor peso promedio del fruto (203 g) y porcentaje de pulpa más semilla (47%) en comparación a P.M.D (187,5 g y 44,7%). La actividad y efectividad de los polinizadores estuvo correlacionada con la temperatura máxima diurna (r=0,69), brillo solar (r=0,56) y humedad relativa (r=0,64). Cuando las dos primeras variables descendieron simultáneamente por debajo de 26°C y menos de tres horas por día, se alcanzaron los mayores porcentajes de fructificación. 2014-04-09 2016-05-02T20:54:16Z 2016-05-02T20:54:16Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistas.ucr.ac.cr/index.php/agromeso/article/view/14200 10.15517/am.v25i1.14200 http://hdl.handle.net/10669/17578 spa Array Copyright (c) 2014 Agronomía Mesoamericana application/pdf Universidad de Costa Rica Mesoamerican Journal of Agronomy; Agronomía Mesoamericana: Vol. 25, Nº 1; 73-83 Agronomía Mesoamericana; Agronomía Mesoamericana: Vol. 25, Nº 1; 73-83 Agronomía Mesoamericana; Agronomía Mesoamericana: Vol. 25, Nº 1; 73-83 2215-3608 1021-7444
