Resumo: | ABSTRACT  Aspects related to the floral biology of Citrus sinensis ‘Pera Rio’ variety were studied in the present work aiming to obtain information about the pollination ecology in the local agriculture. Studies of flowering, anthesis, pollen / ovule ratio, stigmatic receptivity, pollen viability, nectar characterization and floral visitors were carried out. From the data studied, the following information was obtained: C. sinensis variety ‘Pera Rio’ flourishes in two annual periods (dry and rainy), the anthesis occurs from 9:00 AM with duration of 24 hours, during which period stigma receptivity, pollen viability and nectar secretion are highly significant, demonstrating that the species also possesses characteristics of allogenic plants. Apis mellifera was a floral visitor, with a greater number of individuals with a Relative Frequency (RF) of 51.1%. Melipona scutellaris obtained second place in visits with RR = 23.6%; Followed by Trigona spinipes with FR = 17.7%. The two seasons (dry and rainy) presented high similarity (Morisita index = 0.64). C. sinensis has floral biology favorable to cross pollination and bees A. mellifera and M. scutellaris are potential pollinators of this fruit in the conditions in the region of the Recôncavo Baiano. The reproductive system of C. sinensis is mixed, being favorable to entomophilic pollination.
