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.

RESUMO -Foi estudada a biologia da polinização e o sistema reprodutivo de Passiflora coccinea uma Passifloraceae comum na região Amazônica, conhecida popularmente por maracujá-poranga ou tomé-assu. Este estudo foi realizado em uma área perturbada, na Estação Experimental de Silvicultura Tropical do INPA (03º06'08" S, 59º58'54" W), em agosto e setembro de 1999. Dados de morfometria, horário de abertura e tempo de vida das flores foram obtidos. Diariamente reprodução desta espécie de maracujá é a xenogamia visto que não foram produzidos frutos por apomixia e por autogamia. A taxa natural de produção de frutos aumentou de 15% para Palavras-chave: beija-flores, biologia floral, Passifloraceae.Pollination Biology and Breeding System of Passiflora coccinea Aubl. in Manaus, Amazonas, Brazil.ABSTRACT -Pollination biology and breeding system of Passiflora coccinea, a Passifloraceae common in the Amazonian region, popularly known as maracujá-poranga or tomé-assu, were studied in a clearing at the INPA's forestry experimental station (03º06'08" S, 59º58'54" W) in August and September 1999. Data were obtained on floral morphology, blooming time and life span of the flower. Visiting animals, kind of foods taken, visiting time and frequency were the fruits in the area was noted. The flower of P. coccinea presents a syndrome of the ornithophily since it has diurnal anthesis, is red, does not possess any odour, and presents large amounts of nectar. The hummingbirds Amazilia sp. and Phaethornis superciliosus were considered to be its pollinators. Two species of Hymenoptera and Lepidoptera were considered to be pollen and species' breeding system, since fruits were not produced through autogamy and apomixis.

Passion fruit has great prospective to fascinate fruit consumer for its taste and delicious fruit juice and improvement of the economic condition of the fruit grower in the developing countries. The self-incompatibility in the passion fruits is an imperative reason to be considered regarding fruit production. Pollination is an essential for self-sterile crops as passion fruit (Passiflora edulis Sims.). The experiment was conducted in the field and laboratories of the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur, Bangladesh to investigate the fruit setting behavior of passion fruits at during five flashes. We estimated to study fruit setting behavior of passion fruit at different flashes and determine effective pollination method and suitable flashes among five flashes. Result revealed that percent of fruit set of passion fruit was recorded highest; Seeds per plant were recorded highest in third flash when flowers were pollinated by hand compared with self-, and natural pollinations. Length-breadth ratios of fruits in third flashes were recorded higher when pollinates by hand. Individual fruit weight was also recorded higher at third flash. Plants required minimum days from flower anthesis to full maturity during third flash. On the other hand, fruit growth behavior of hand pollinated flowers was recorded higher during third flash of passion fruit. Results indicated that all studied characteristics of fruit and seed of passion fruit of third flash performed best.
