La polinización natural en el maracuyá (Passiflora edulis f. flavicarpa Degener) como un servicio reproductivo y ecosistémico.

Abstract

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 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.

Folin-Ciocalteu Reaction Alternatives for Higher Polyphenol Quantitation in Colombian Passion Fruits

“…Fruits in the Passifloraceae family, mainly native to Central and South America, comprise over 450 different species [ 1 , 2 ]. More than 80 edible Passifloras are cultivated throughout the world [ 3 ]. Passiflora edulis Flavicarpa, yellow passion fruit or maracuyá, is a popular and year-long harvested Colombian fruit.…”

Abejas en Sistemas Agrícolas: Revisión De La Diversidad Taxonómica Y Funcional, Y Perspectivas De Investigación

“…Para maracuyá se encontraron cinco estudios realizados en las zonas de vida Subandina y Andina, entre los 1300 y 2200 m.s.n.m. (Calle et al, 2010;Arias-Suárez et al, 2014;González y González, 2015;Rodríguez-Calderón, 2016;Bezerra et al, 2019). Para el cultivo de palma se registraron cuatro estudios en la zona de vida tropical de la región amazónica (Guerrero-Olaya y Núñez, 2017; Núñez y Carreño, 2017), de la Orinoquia, el Pacífico (Núñez y Carreño, 2016) y de la región Caribe (Brieva-Oviedo y Núñez, 2020).…”

“…Muchos cultivos agrícolas son polinizados por abejas con rasgos funcionales específicos, como se evidencia en los cultivos de maracuyá (Calle et al, 2010;Arias-Suárez et al, 2014;González y González, 2015;Rodríguez-Calderón, 2016;Bezerra et al, 2019). Por esto, se deben ampliar las investigaciones enfocadas a la diversidad funcional de abejas y su relación con la polinización efectiva de los sistemas agrícolas donde actúan como visitantes florales, ya que los rasgos funcionales de las especies determinan la legitimidad de la polinización (Shaw et al, 2017).…”

Responses of landraces and commercial cultivars of yellow passion fruit to the prevalence of Fusarium oxysporum

“…Other descriptors that distinguished these groups are related to the flower, such as the length of the anthers and the diameter of the stigma. Passionfruit is an allogamous plant that has structures in the flower to generally attract bumblebees that assist in pollination (Arias-Suárez et al, 2014). Thus, in the principal component analysis carried out with the floral morphological data (Fig.…”
