| ABSTRACT Large-scale commercial production of pitaya is recent and there is little information on pollination and fruiting in this crop. Therefore, the objective of the present study was to investigate if the Africanized honeybee (Apis mellifera), frequent visitor of pitaya flowers (Hylocereus undatus and H. polyrhizus), plays any relevant role in the pollination of these cacti species, both in terms of fruit quantity and fruit quality. The study consisted of four treatments: natural pollination; restricted pollination; nocturnal pollination and pollination by A. mellifera, and all fruits were harvested and analyzed at 30 days after setting. Each treatment was evaluated in the number of fruits produced, total weight of the fruit; skin weight; pulp weight;... |

| ABSTRACT The present work aimed to study floral biology, pollination requirements and the behavior of floral visitors in two species of pitaya, Hylocereus undatus and H. polyrhizus, in Northeastern Brazil. The experiment was carried out through diurnal and nocturnal observations and the use of flowers bagged or accessible to visitors. Results showed that flowers of both species are similar both in anatomical and functional traits. They are large, with nocturnal anthesis onset and attract night and daytime flower visitors. The floral visitors found were sphinx moths, ants, wasps and bees, with Apis mellifera accounting for 86.1% of visits to flowers. The H. undatus species is independent of biotic pollination to set and produce large and well-shaped fruits,... |
