description The plant-hummingbird interaction is fundamental for pollination in cloud forests. This research evaluated the effectiveness of pollination by hummingbirds in four species of plants in the Finca Zingara, Cali, Colombia. We assessed the hummingbird visits, the reproduction of the plants, the flowers’ energetic offer, and the deposition of pollen on the stigmas. We found that Guzmania multiflora was the most visited species by hummingbirds, followed by Cavendishia adenophora. In Columnea ferruginea and Columnea anisophylla we observed only four and one hermit hummingbird visits, respectively. The four species exhibit allogamy, Guzmania multiflora, and Cavendishia adenophora are auto compatible. Meanwhile, the two Columnea species are auto incompatible. The pollen that hummingbirds lay on the stigma is mainly legitime (Guzmania multiflora: 77,8% and Cavendishia adenophora: 51,6%). The higher volume of nectar accumulated during the day was produced by Guzmania multiflora: 28,53 µl and Cavendishia adenophora: 23,91 µl. The higher sucrose concentration in nectar was produced by Columnea ferruginea: 20,14% and Cavendishia adenophora: :17,4%. We conclude that hummingbirds are the effective pollinators of Guzmania multiflora and Cavendishia adenophora. Furthermore, for the hummingbirds in this study, it was more important to visit flowers of the species that produce the highest amount of nectar, than flowers of species with the highest sucrose concentration.

La interacción planta-colibrí es fundamental para la polinización en los bosques de niebla. Esta investigación evaluó la efectividad de la polinización por colibríes en cuatro especies de plantas en la Finca Zíngara, Cali, Colombia. Se evaluaron las visitas de colibríes, la reproducción de las plantas, la oferta energética de las flores y la deposición de polen en los estigmas. Se encontró que Guzmania multiflora fue la especie más visitada por colibríes, seguida por Cavendishia adenophora. En Columnea ferrugineay Columnea anisophylla sólo se observaron cuatro y una visita de una especie de colibrí ermitaño, respectivamente. Las cuatro especies de plantas presentan alogamia, Guzmania multiflora y Cavendishia adenophora son autocompatibles, mientras que las dos especies de Columnea son autoincompatibles. El polen que depositan los colibríes en el estigma es principalmente legítimo (Guzmania multiflora: 77,8%, Cavendishia adenophora: 51,6%). El mayor volumen de néctar acumulado en el día fue producido por Guzmania multiflora: 28,53 µl y Cavendishia adenophora: 23,91 µl. La mayor concentración de néctar la produjeron Columnea ferruginea: 20,14% y Cavendishia adenophora: 17,4%. Se concluye que los colibríes son polinizadores efectivos de Guzmania multiflora y Cavendishia adenophora. Además, para los colibríes en este estudio fue más importante visitar flores de las especies que producen mayor cantidad de néctar, que flores de especies con mayor concentración de sacarosa.  Universidad Pedagógica y Tecnológica de Colombia 2020-07-23 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion texto application/pdf https://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/10466 10.19053/01217488.v11.n2.2020.10466 Ciencia En Desarrollo; Vol. 11 No. 2 (2020): Vol 11, Núm.2 (2020): Julio-Diciembre; 53-63 Ciencia en Desarrollo; Vol. 11 Núm. 2 (2020): Vol 11, Núm.2 (2020): Julio-Diciembre; 53-63 2462-7658 0121-7488 spa https://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/10466/9872 Derechos de autor 2020 CIENCIA EN DESARROLLO
